According to
https://www.typescriptlang.org/docs/handbook/module-resolution.html#base-url,
`baseUrl` affects all non-relative imports. Additional `paths` mapping
can be specified for more control. However, if none of the `paths`
matches, it still falls back to the default `*:*` mapping. Confirmed by
invoking `tsc` with different configs.
Fixes#22663.
Previously, we would use any error that was added during the step
execution as an error for this particular step.
This produces false positives, for example failing `page.click` call
that happened during `context` teardown was producing an error and
marking teardown is failed. However, in reality, the test itself has
failed, while teardown has not.
New approach uses test step hierarchy to inherit errors from child steps
to the parent step. This does not regress the original fix where
`expect.soft` errors are surfaced in the parent step.
See also #19973 that introduced the original logic.
There was a single test fixture scope that covers all hooks, modifiers
and test function. Now beforeAll-like modifiers, beforeAll and afterAll
hooks get a scope each.
Fixes#22256.
Attachments with `path` are stored as `resources/sha1.ext` zip entries
and extracted under `report-dir/tmp` when merging. This way normal
fs.readFile keeps working as before even thought the file path is
different. The clients should rely on `attachment.name` instead of
`attachment.path` when deriving user visible titles in the UI. If this
turns out not to be the case we can reconsider later.
#10437
This patch:
- changes the `childProcess` fixture to reliably SIGKILL all descendants
(children and grand-children, regardless of their process group).
This is achieved using the `ps` command to build the process tree, and
then send
`SIGKILL` to the descendant process groups.
- changes the `runCLI` fixture to **not** auto-close codegen by default;
the `childProcess` fixture will clean up all processes. This makes
sure that all `runCLI.waitFor()` commands actually wait until the
necessary
output.
- for a handful of tests that do actually want to auto-close codegen,
introduce an optional `autoCloseWhen` flag for the `runCLI` fixture
that makes sure to close the codegen once a certain output was reached.
With two contexts in the same test, we can get:
- `<testId>.network` and `<testId>-1.network` files;
- for export, we can copy `<testId>.network` into `<testId>-1.network`
and try to copy into a file when another trace is reading from it.
Fixes#22089.
`x-playwright-debug-log: value` headers are printed to `pw:browser`
debug log.
`x-playwright-attachment: name=value` headers are attached to each test.
Fixes#21619.
We point `tracesDir` inside `test-results`, so it is removed between
test runs, while reused context is still writing there.
To fix the issue, we can now pass `env.PW_TEST_REUSE_CONTEXT`.
References #21993.
The intent of default test match is allowing `example.spec.ts` and
`example.test.ts` files. However, it was also matching `test.example.ts`
that should not be considered a test by default.
Fixes#21979.
The new message looks like this:
```
Test finished within timeout of 500ms, but tearing down "playwright configuration" ran out of time.
Please allow more time for the test, since teardown is attributed towards the test timeout budget.·
```

BREAKING CHANGE: Drop support for React 17 and earlier
Support for React 17 an earlier is provided by
`@playwright/experimental-ct-react-17`
Closes#19923
This enables `allowDeclareFields` flag that allows code like:
```ts
class Foo {
declare prop: string;
}
```
Declaring is a workaround for inheritance vs property initialization
issues.
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#the-usedefineforclassfields-flag-and-the-declare-property-modifier
For `allowDeclareFields` to work, we have to run
plugin-transform-typescript before plugin-proposal-class-properties and
few others, so this change migrates from preset-typescript that always
runs last to individual plugin-transform-typescript, and reorders some
plugins.

There is currently a bug when running `node@18.14.2` when running with
experimentalLoader
```

This came from my test `vrt.spec.ts` which had a non package import
inside of it
```ts

```
The test run failed due to node imports not returning fileUrls when
resolved.

This reverts commit 303c5998f8.
Reason for revert: I tried enabling `ssim-cie94` by default on
ionic-framework test suite, and it proves to be overly strict for their
usecase.
This implementation is based on the [original
PR](https://github.com/microsoft/playwright/pull/19691) by @kevin940726.
It makes the reporter produce single file when there is no sharding and
multiple out-of-line report-x-of-y.zip reports which are automatically
merged together when put in one folder.

The option defines a comparator to be used to compare images.
Possible values are `"pixelmatch"` and `"ssim-cie94"`.

I had to manually inject `window.playwrightReportBase64` data into
`playwright/packages/html-reporter/index.html` when developing,
wondering if there's any method I don't know.
Introduce config.globalScripts. Tests from the matching files will run
before all projects. We'll only allow beforeAll/afterAll instead of
tests in such files (next PR).
Global scripts are executed as part of 'Global Scripts' project which is
not present in FullConfig.projects but may be referenced by
corresponding global setup Suites.

#19576 introduced a regression where the CLI reporters displayed some
times with way too many decimals. e.g. 7.123456789ms.
Prior to #19576, there were two monotonicTime implementations; that PR
updated the reporters to use the common definition that had existed in
utils.ts. However, that introduced a regression in the base.ts reporters
which used the ms duration humanizing package which did not account for
the more precise decimals used by the shared monotonicTime function.
This fix removes the dependency on the third-party ms package and now
consistently uses Pavel's humanize function which the HTML reporter had
been using and proved to have better defaults for decimals.
Additionally, we add more test coverage to limit future regressions
since this was caught in passing.
Closes#19556.
Relates #19576.
Note: this keeps existing behavior of `undefined` in `test.use()`
reverting to the config value and not to the original default value.
References #19615.
This patch implements a new image comparison function, codenamed
"ssim-cie94". The goal of the new comparison function is to cancel out
browser non-determenistic rendering.
To use the new comparison function:
```ts
await expect(page).toHaveScreenshot({
comparator: 'ssim-cie94',
});
```
As of Nov 30, 2022, we identified the following sources of
non-determenistic rendering for Chromium:
- Anti-aliasing for certain shapes might be different due to the
way skia rasterizes certain shapes.
- Color blending might be different on `x86` and `aarch64`
architectures.
The new function employs a few heuristics to fight these
differences.
Consider two non-equal image pixels `(r1, g1, b1)` and `(r2, g2, b2)`:
1. If the [CIE94] metric is less then 1.0, then we consider these pixels
**EQUAL**. (The value `1.0` is the [just-noticeable difference] for
[CIE94].). Otherwise, proceed to next step.
1. If all the 8 neighbors of the first pixel match its color, or
if the 8 neighbors of the second pixel match its color, then these
pixels are **DIFFERENT**. (In case of anti-aliasing, some of the
direct neighbors have to be blended up or down.) Otherwise, proceed
to next step.
1. If SSIM in some locality around the different pixels is more than
0.99, then consider this pixels to be **EQUAL**. Otherwise, mark them
as **DIFFERENT**. (Local SSIM for anti-aliased pixels turns out to be
very close to 1.0).
[CIE94]: https://en.wikipedia.org/wiki/Color_difference#CIE94
[just-noticeable difference]:
https://en.wikipedia.org/wiki/Just-noticeable_difference
The behavior regarding filters (both in config, command line and .only)
is the following:
- if some of tests match and none of setup match then we'll run all
setup files and all matching tests
- otherwise the filters apply to setup files the same way as to regular
tests
Running `npx playwright test file:123` will have the following behavior
- if only test files match then only matching subset of tests will run
but all setup files will run as well
- if only setup files match the filter then only those setup tests will
run
- if both setup and test files match an error will be thrown
This patch:
- updates documentation to lead users from `TestConfig.snapshotDir` and
`testInfo.snapshotSuffix` to `TestConfig.snapshotPathTemplate` as a
better and more flexible alternative.
- drops `{snapshotSuffix}` from documentation
- stops using `snapshotSuffix = ''` in our own tests and switches us
to the `snapshotPathTemplate`.
- adds `{testName}` token.
- Use `snapshotPathTemplate` for docker screenshots in html-reporter
- Mark the snapshot path template test as slow since it re-spawns
worker for each project.
- Fix docker smoke tests
This configuration option allows to set a string with template
values for precise control over snapshot path location.
An example of `snapshotPathTemplate` usage:
```ts
// playwright.config.ts
// Notice the `testDir` configuration!
export default {
testDir: './tests',
snapshotPathTemplate: './__screenshots__/{platform}/{projectName}/{testFilePath}/{arg}{ext}',
}
```
Currently supported "magic tokens" inside the `snapshotPathTemplate`
are:
- `{testDir}` - project's `testDir`
- `{snapshotDir}` - project's `snapshotDir`
- `{platform}` - `process.platform`
- `{projectName}` - Project's sanitized name
- `{testFileDir}` - Directories in relative path from `testDir` to test
file path (e.g. `page/` in the example below)
- `{testFileName}` - Test file name (with extension) (e.g.
`page-click.spec.ts` in the example below)
- `{testFilePath}` - Relative path from `testDir` to test file path
(e.g. `page/page-click.spec.ts` in the example below)
- `{ext}` - snapshot extension (with dots)
- `{arg}` - joined snapshot name parts, without extension (e.g.
`foo/bar/baz` in the example below)
- `{snapshotSuffix}` - `testInfo.snapshotSuffix` value.
Consider the following file structure:
```
playwright.config.ts
tests/
└── page/
└── page-click.spec.ts
```
The following `page-click.spec.ts`:
```ts
// page-click.spec.ts
import { test, expect } from '@playwright/test';
test('should work', async ({ page }) => {
await expect(page).toHaveScreenshot(['foo', 'bar', 'baz.png']);
});
```
Fixes#7792
Per discussion in #12950, adding sanitized name to the output filename
prefix. This can make debugging easier, and the filename structure more
human friendly.
We have to reliably know whether test timed out or not, and soft expect
error could have marked it with `status=failed` but it would still time
out. Now we have a separate `_didTimeout` flag for this.
Fixes#18023.
Fixes#17412.
Supercedes #17413.
- if configured via playwright.config.ts, relative paths should be
relative to the config.
- if configured via env var, should be relative to `cwd`
Allows to set workers as a percentage of logical CPUs, for example
"50%".
Examples :
```bash
npx playwright test --workers 3
npx playwright test --workers 50%
```
```js
const config: PlaywrightTestConfig = {
// ...
workers: '33%',
}
```
This patch opts into the `__screnshots__` folder snapshot management
for docker.
With this patch, docker-originating snapshots will be stored in the
following folder:
```
{testDir}/__screenshots__/{projectName}/{testFilePath}/{snapshotName}
```
Where `{testFilePath}` is a test file path relative to `testDir`
Drive-by: introduce and document the `PLAYWRIGHT_DOCKER` environment
variable that enables docker integration.
This moves some expect() matchers tests from test runner tests to page tests,
because these are implemented through a library call anyway.
Makes tests more readbable, faster and easier to test specific details.
Also, exlude certain errors from triggering this message:
- `no tests found`
- `duplicate test titles are not allowed`
- `--forbid-only found a focused test`
- `Timed out waiting 3600s for the entire test run`
In the following example, `locale` inside the `describe`
would be reverted to the default value:
```js
test.use({ locale: 'en-GB' });
test.decsribe(() => {
test.use({ locale: undefined });
});
```
Line reporter now shows stats in addition to the test name:
```
[chromium] › page/page-click-react.spec.ts:108:1 › should not retarget when element changes on hover
[21/93] Passed: 17 Flaky: 0 Failed: 0 Skipped: 4 (7s)
```
fix(test runner): more firendly test duration
Reported test duration now does not include time spent in
`beforeAll`, `afterAll` and fixtures that have a separate timeout.
This is to avoid different reported test execution time,
depending on the test execution order.
Fixes#8206.
Since #8206 is a long-awaited (~ 1 year old), popular (~ 45 reactions, frequently requested in community channels, etc.), this PR aims to unblock folks.
Notably, we do not innovate on the `webServer` API, despite knowing we're not in love with it. We'll save the innovation for either Plugins or a new `LaunchConfigs` option. (We haven't yet arrived at a Plugin API we like, and instead of launching a new option guessing what the "better" launchConfig API would be, let's wait and see how folks use this new Array-variant of `webServer` which—despite its name—can be used for non-Web Server launches!
When running without tty, line reporter outputs a line for each
percent of the tests, thus limiting the output to ~100 lines.
In addition, reporters now support PLAYWRIGHT_LIVE_TERMINAL
env variable to force tty mode.
Useful to set some options without coming up with an artificial name.
```js
test.describe(() => {
test.use({ colorScheme: 'dark' });
test('my test', () => {});
})
```
Currently, it is possible to run a function, e.g. a second `beforeEach` hook,
that will receive `null` for the fixture that has already failed before.
This PR skips running any user function that uses a fixture that has already
failed, just like if the fixture would be initialized again and failing for
the second time.
Currently, if `text.fixme()` or `test.skip()` is used within a test, we
add a `fixme` or `skip` annotation. However, if the wrapper style is
used:
```
test.fixme('should work', () => {…})
```
the annotations were missing. This change adds annotations for the
above.
These annotations are important for reporting purposes and knowing
exactly what flavor of "skipped" was used.
Fixes#15239.
Some of the current timeout error messages are confusing, because they do not suggest that the issue is most likely a slow test. This PR updates timeout messages as follows:
- Test timeout of 30000ms exceeded.
- Test timeout of 30000ms exceeded while setting up "browser".
- Test timeout of 30000ms exceeded while tearing down "context".
- Test timeout of 30000ms exceeded while setting up "playwright configuration".
- Test timeout of 30000ms exceeded while running "beforeEach" hook.
- Test timeout of 30000ms exceeded while running "afterEach" hook.
- "beforeAll" hook timeout of 30000ms exceeded.
- "afterAll" hook timeout of 30000ms exceeded.
- Worker teardown timeout of 30000ms exceeded.
- "skip" modifier timeout of 30000ms exceeded.
- Fixture "myCustomFixture" timeout of 5000ms exceeded.
Previously, screenshot was taken after hooks and fixtures teardown.
However, hooks can easily modify the state of the page, and
screenshot would not reflect the moment of failure.
Instead, we take screenshots immediately after the test function
finishes with an error.
These mean "I don't want to specify this fixture/option"
instead of "I want the value of undefined", aligned with how TypeScript works.
We already do similar things in the config.
Fixes#14904.
This is done to make looking at the raw contents of the report
friendlier when using a file browser. However, it should be noted, the
public API of the HTML Reporter makes no guarantees of its contents
structure/layout/naming-conventions.
If the tests are in an explicitly configured testDir (either at the global config level or per project) .gitignore filters are not applied.
Fixes#14381
There are a few issues this covers:
- Some fixtures like `page` and `context` are not allowed in `beforeAll`
hooks, so using them in automatic fixture makes it throw.
- Running automatic fixture solely for `afterAll` is unexpected.
This currently happens when `afterAll` is run for cleanup after
fixture timeout/throw.
For built-in playwright fixture, we keep `'all-hooks-included'` auto mode.
Added a doc explaining the execution order.
Note: all toHaveScreenshot tests still use `__screenshots__` directory
for their expectations. One more test was added to make sure that
by default, `toHaveScreenshot` uses old snapshots.
feat: support experimental doc entries
- Params/options/members are marked as experimental in the docs.
- `experimental.d.ts` is generated that contains all types and
includes experimental features.
- `experimental.d.ts` is references in our tests so that we
can test experimental features.
- `fonts` option is restored as experimental.
- Always show a fixture that was running during timeout.
- Give custom titles to built-in fixtures.
- Specify setup/teardown fixture phase in the message.
- Split connect vs launch browser fixtures for better naming.
Example timeout message:
```log
Timeout of 2000ms exceeded while running fixture "built-in playwright configuration" teardown.
```
A few changes:
- `Matchers<R, T>` now carries both return and argument type.
- Based on the argument type, we apply playwright-specific Page/Locator matchers.
- Return type is usually void, unless wrapped with `expect.resolves`,
`expect.rejects` or `expect.poll()`.
- To preserve compatibility with any extended types in the wild,
argument type is optional.
If you typo'd an `expect` property, you got a cryptic error message:
```
Uncaught TypeError: Cannot create proxy with a non-object as target or handler
```
Now we get this nice friendly message:
```
1) a.spec.ts:6:9 › explodes ======================================================================
Error: expect: Property 'toBeLessThen' not found.
Did you mean 'toBeLessThan'?
See https://playwright.dev/docs/test-assertions for available options and documentation.

```
Fixes#13218
Previously, we always formed groups consisting of a single test.
Now, we group tests that share `beforeAll`/`afterAll` hooks into
`config.workers` equally-sized groups.
This patch:
- starts using directory of `package.json` to resolve default
output directory path
- starts using either `package.json` directory or configuration
directory to resolve all relative paths
References #12970
Resolves#11318.
* Adds `TestConfig.attachments` public API. (We opted to not implement an analog to the async `TestInfo.attach(…)` API.)
* Adds `TestConfig.attachments` to common reporters.
* Dogfoods some git and CI-info inference to generate useful atttachments
* Updates HTML Reporter to include a side bar to present a pre-defined set of attachments (a.k.a git/commit context sidebar)
Here's what it looks like:
<img width="1738" alt="Screen Shot 2022-03-21 at 3 23 28 PM" src="https://user-images.githubusercontent.com/11915034/159373291-8b937d30-fba3-472a-853a-766018f6b3e2.png">
See `tests/playwright-test/reporter-html.spec.ts` for an example of usage (for dogfood-ing only). In the future, if this becomes user-facing, there the Global Setup bit would likely become unnecessary (as would interaction with attachments array); there would likely just be a nice top-level config and/or CLI flag to enable collecting of info.
This patch aligns the strategies that are used to generate new
screnshot expectations and to compare screenshot expectations against
baseline.
With this patch, `toHaveScreenshot` will:
- when generating a new expectation: will wait for 2 consecutive
screenshots to match and accept the last one as expectation.
- when given an expectation:
* will compare first screenshot against expectation. If matches,
resolve successfully
* if first screenshot doesn't match, then wait for 2 consecutive
screenshots to match and then compare last screenshot with the
expectation.
An example of a new detailed call log:
```
1) a.spec.ts:3:1 › should work ===================================================================
Error: Screenshot comparison failed:
20000 pixels (ratio 0.03 of all image pixels) are different

By default, fixtures share timeout with the test they are instantiated for.
However, for more heavy fixtures, especially worker-scoped ones, it makes
sense to have a separate timeout.
This introduces `{ timeout: number }` option to the list of fixture options
that opts the fixture into a dedicated timeout rather than sharing it
with the test.
Turns out relying on PWTRAP in stack is not reliable: depending on the
call structure, the stack might be cut unpredictably by Node.js.
This patch removes PWTRAP and instead plumbs explicit stack and
pre-set `apiName` all the way down to `wrapApiCall`.
This patch:
- adds call logs to track screenshot timeouts, e.g. due to
waiting for web fonts
- makes sure all snapshot expectations have `.png` extension
- throws a polite error when given a buffer or a string instead of a
page or a locator
- removes stray NL between error description and call log
- makes sure `apiName` is always correct (and adds a test for it)
- Line reporter now shows stats in addition to the test name:
```log
[chromium] › page/page-click-react.spec.ts:108:1 › should not retarget when element changes on hover
23% [21/93] Passed: 17 Flaky: 0 Failed: 0 Skipped: 4 (7s)
```
- When connected to a TTY or with `env.PLAYWRIGHT_LIVE_TERMINAL`
set to anything but `'0'` or `'false'`, line reporter updates in place.
- When not connected to a TTY, line reporter prints an update
after each ~1% of tests done, so it never prints more than 100 lines.
- Updated tests to the golden style.
Use a top-level .env file to control the internal testing setup.
This allows for easy manipulation of environment variables regardless
of your setup (VSCode Extension, CLI, etc.).
This patch adds support to multiple diffs. These are possible
due to soft assertions.
Drive-by: rename second screenshot in `toHaveScreenshot` failure when
re-generating expectations from "expected" to "previous".
This patch:
- Enables configuration of certain defaults for some options of `expect.toHaveScreenshot` method via `TestProject.expect.toHaveScreenshot` property
- Sets sensible defaults for these options:
* `fonts: "ready"`
* `animations: "disabled"`
* `size: "css"`
This patch reverts 2 commits that removed the feature from the method:
- "fix: explicitly ignore maxDiffPixels in toMatchSnapshot (#12570)"
commit b8af8458d6.
- "chore: remove `maxDiffPixels` from toMatchSnapshot (#12539)"
commit a3dff45974.
The `screenshotsDir` option controls the expectation storage
for `toHaveScreenshot()` function.
The new expectation management for screenshots has the following
key properties:
- All screenshots are stored in a single folder called `screenshotsDir`.
- Screenshot names **do not** respect `snapshotDir` and `snapshotSuffix`
configurations.
- `screenshotsDir` is configurable per project. This way a "smoke tests"
project can re-use screenshots from "all tests" project.
- Host platform is a top-level folder.
For example, given the following config:
```js
// playwright.config.ts
module.exports = {
projects: [
{ name: 'Mobile Safari' },
{ name: 'Desktop Chrome' },
],
};
```
And the following test structure:
```
smoke-tests/
└── basic.spec.ts
```
Will result in the following screenshots folder structure by default:
```
__screenshots__/
└── darwin/
├── Mobile Safari/
│ └── smoke-tests/
│ └── basic.spec.ts/
│ └── screenshot-expectation.png
└── Desktop Chrome/
└── smoke-tests/
└── basic.spec.ts/
└── screenshot-expectation.png
```
Previously, we used to skip all the tests from the same file when
any `beforeAll` fails in the file.
Now, we only skip the rest of the tests affected by this particular
`beforeAll` and continue with other tests in the new worker.
Reland: worker.stop() before worker.run() was hanging because
`_runFinished` promise was not initially resolved.
---
This moves `beforeAll`, `afterAll` and some modifiers from running
as a separate entity into running inside a test.
Pros:
- All errors are reported as test errors.
- All artifacts are collected as test artifacts.
- Reporters support this out of the box.
Details:
- Each test computes the necessary hooks to run and runs them.
- Teardown is usually performed during the test (on test failure or worker stop).
- `skipRemaining` is added to `DonePayload` to preserve the behavior
where `beforeAll` hook failure skips subsequent tests.
This behavior can now be improved to only target tests affected by this hook.

- All artifacts are collected as test artifacts.
- Reporters support this out of the box.
Details:
- Each test computes the necessary hooks to run and runs them.
- Teardown is usually performed during the test (on test failure or worker stop).
- `skipRemaining` is added to `DonePayload` to preserve the behavior
where `beforeAll` hook failure skips subsequent tests.
This behavior can now be improved to only target tests affected by this hook.
This uses `Module._resolveFilename` to intercept module resolution and
check `tsconfig.paths` similarly to pirates usage ot `Module._compile`.
Previously, we resolved during compilation that required reproducible
resolution due to caching. Now we can resolve as we go and support
all `tsconfig.paths`.
- `stdout.isTTY` controls whether list reporter updates lines or just adds them;
- `env.CI` is used in a few places to affect the defaults:
- whether to open interactive html;
- default reporter dot/line;
- default terminal reporter added to non-terminal reporters;
- `env.PWTEST_SKIP_TEST_OUTPUT` is removed;
- `env.PW_TEST_DEBUG_REPORTERS` is introduced specifically for tests.
This way we control the timeout error message from the runner,
so that later on we can differentiate between test timeout, fixture
timeout and hook timeout.
This patch prepares for the `toHaveScreenshot` implementation
by splitting common parts from `toMatchSnapshot`.
Drive-by: fix default extension generation from `.bin` to `.dat`
for unknown buffers.
This patch adds additional options to `toMatchSnapshot` method:
- `pixelCount` - acceptable number of pixels that differ to still
consider images equal. Unset by default.
- `pixelRatio` - acceptable ratio of all image pixels (from 0 to 1) that differ to still
consider images equal. Unset by default.
Fixes#12167, #10219
In experimental ESM mode a child process is forked in order to run the tests. Currently the exit code of this child process is not propagated to the exit code of the parent process, which means that the process exits with a status code of `0` even if some of the tests failed.
This makes it difficult to use Playwright in CI in experimental mode, as the CI pipeline as a whole will pass despite the test failures.
This change addresses this by propagating the exit code in the case where it is non-zero.
