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.
Prior to this change, we were pre-maturely stopping a worker (since it
was deemed redundant under a race condition), and then we immediately
created a new worker with the same hash to finish off the test run. The
worker creation is expensive, so this slowed down the overall test run
time.
See the following for logs of the old code illustrating the extra stops and starts: https://gist.github.com/rwoll/1c592ed9e8f9169274fa972674de6703
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.
```
To make launch/connect not affect the test timeout:
- `browser` fixture is declared with `timeout: 0`.
- Default timeouts are set to 30sec for launch and 3min for connect.
Previously, we were guessing whether something is optional from the
comment (looking for stuff like "defaults to" or "optional").
To remove this error-prone technique, every optional property or
argument (but not option) is explicitly marked with "?".
As a result, fix documentation issues:
- Removed `TestStep.data` that is not a thing.
- Added `TestConfig.name` documentation.
- Refined a lot of optional types in the documentation.
- Aligned `test.fail()` and `test.slow()` docs with `test.skip()`.
- Strict set of docs vs types inconsistensies in the generator
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.
fix: wait for worker to be ready before initializing
The test dispatcher waits until a worker is ready before sending the
`init` message. This guarantees that the worker process is listening for the
message. Otherwise, the worker process might miss the `init` message and
the subsequent `run` message would crash the worker.
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.
5 | const { test } = pwt;
6 | test('explodes', () => {
> 7 | expect.soft(1).toBeLessThen();
| ^
8 | });
9 |
```
Fixes#13218
This has two values:
- `"hide"` to hide input caret for taking screenshot
- `"initial"` to keep caret behavior unchanged
Defaults to `"hide"`.
Fixes#12643
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.
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`.
Currently, running `npx playwright test` in a subfolder of your project
will result in a `test-results` folder created in your `cwd`.
This is unexpected; instead, we should always resolve all paths
against `rootDir` - directory that contains config.
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.
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"`
New default is based on the very (unscientific) output of repeated a few
times:
```
$ for i in `seq 5 13`; do time npm run ctest -- --reporter=line --workers=$i 'page/*' 'selector*' 'channels*' 'resource-timing*'; done
```
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.
