Otherwise, we might split the `beforeAll`-grouped test group into
`workers` parts instead of `shard.total` parts as the user would expect.
Fixes#33077.
The diff is now shown inline in the errors list.
There are 2 possible failures of toHaveScreenshot
* Previous and actual snapshot mismatch. In this case html report will
show diff between Actual/Previous and have Expected as a separate
screenshot.
* Actual/Previous are equal but they differ from the expected. In this
case html report only contains Actual/Expected images and the diff.

Fixes https://github.com/microsoft/playwright/issues/30160
### Description:
This pull request introduces the ability to specify custom locations for
test steps in Playwright. By enabling the provision of arbitrary
locations to the test.step method, it resolves the limitation where
helper methods obfuscate the original call site, providing more accurate
and meaningful location data in test reports.
### Motivation:
To enhance the utility and clarity of test reports in Playwright.
Specifically, it addresses the need to trace test steps back to their
precise location in the code, which is especially important when steps
are abstracted in helper functions. This feature is crucial for
maintaining accurate documentation and facilitating debugging processes.
### Changes:
Added functionality to pass a custom location object to test.step.
### Expected Outcome:
This PR is expected to significantly improve the precision and
usefulness of diagnostic data in test reports by allowing specific
locations within helper functions to be accurately documented. It
facilitates better tracking of test executions and simplifies the
debugging process, making it easier for developers to understand and
address issues within complex tests.

**Code Check**
I conducted tests on this new feature by integrating it into some
existing test codes, and it worked well. I will attach the code used for
testing and a screenshot showing the successful outcome.

Closes https://github.com/microsoft/playwright/issues/32578.
Adds a buffer mode that can be toggled by pressing <kbd>b</kbd>. When
engaged, changed test files are collected and shown on screen. The test
run is then kicked off by pressing <kbd>Enter</kbd>.
This changes the signal to start a test run from <kbd>Cmd+s</kbd> to a
<kbd>Enter</kbd> press in the test terminal. It should help users with
auto-save and make it easier to run on long-running tests. It feels very
similar to running `npx playwright test`, but without having to write a
filter.

Changes `expect.extend` behaviour so that it doesn't mutate the global
instance and behaves closer to what users expect. This is formally a
breaking change, and I had to remove a test that asserts the breaking
behaviour.
TODO:
- [x] decide wether this is a separate method or a flag for
`expect.extend`
- [x] figure out if we need to change docs
We now hopefully align with `moduleResolution: bundler` tsconfig option,
allowing directory imports in every scenario, and allowing proper module
imports when not going through the type mapping.
This regressed in #32078. Fixes#32480, fixes#31811.
Instead of plumbing it through a custom unspecified config field, make
it a part of plugin interface.
Additionally, use task runner for starting/stopping dev server.
This pull request introduces initial support for the WebDriver BiDi
protocol in Playwright. The primary goal of this PR is not to fully
implement BiDi but to experiment with the current state of the
specification and its implementation. We aim to identify the biggest
gaps and challenges that need to be addressed before considering BiDi as
the main protocol for Playwright.
Closes https://github.com/microsoft/playwright/issues/32076.
This PR rewrites `watchMode.ts` to use `TestServer` under the hood. It's
essentially a complete rewrite, so don't pay too much attention on the
old implementation. Note that there's no changes to tests, so all
behaviour we have specced out there still works.
To make this work without a superfluous WebSocket connection, I had to
refactor `TestServerConnection` a little. Originally, I pulled this into
a [separate PR](https://github.com/microsoft/playwright/pull/32132), but
then realised how small the refactoring is. So it's in this PR now. Let
me know if you'd like to land it separately.
Our CI operates on shallow clones. In vcs.ts, we perform a check for
shallow clones in `process.cwd()` instead of the test directory. This
makes the test in
3c208aeeff/tests/playwright-test/only-changed.spec.ts (L201)
failing in CI, but only for PRs. The fix is to perform the check on. the
test directory.
Closes https://github.com/microsoft/playwright/issues/32331
We're already passing the `outputDir` param to the UI, but the UI isn't
passing it back to the TestServer. This PR fixes that. I've added it to
`listTests`, which is requires to that
`TestServerDispatcher#_ignoredProjectOutputs` is populated with the
correct output dir. And i've added it to `runGlobalSetup`, which is what
the bug report was about.
Closes https://github.com/microsoft/playwright/issues/32256
We were expecting all errors to be of type `ExpectError`, but apparently
`expect` propagates rejections in the polling functions right through.
So we also need to handle that case.
I wonder if we have more cases of this. Would it make sense to enable
`useUnknownInCatchVariables` in TypeScript?
Closes https://github.com/microsoft/playwright/issues/32180
I was briefly wondering if we should output a log line a la "no tests
found", but my understanding is that that's the reporters job - so I
didn't change anything in that regard.
When two fixtures have different time slots, timeout in the first one
should not prevent the second one from tearing down.
Similarly, timeout in afterEach hook should not prevent fixture
teardowns.
This allows any time slot that has a legitimate timeout of zero to be
updated later on. See test for an example.
Previously, setting timeout to zero at any moment was considered a
"debug mode" and any subsequent timeouts were ignored.
Closes https://github.com/microsoft/playwright/issues/32070. We were
applying `additionalFileMatcher` not just to `filteredProjectSuites`,
but also to `projectSuites`. `projectSuites` is where we take dependency
projects from, though - so `--only-changed` led to empty dependency
projects, resulting in the reported bug.
The fix is to only apply `additionalFileMatcher` on
`filteredProjectSuites`.
Supercedes https://github.com/microsoft/playwright/pull/31915, closes
https://github.com/microsoft/playwright/issues/31811.
When TypeScript resolves a specifier via path mapping, it does not
interpret `package.json`. If path mapping resolves to a directory, it
only looks at the `index.js` file in that directory if it's in CommonJS
mode.
We need to mirror this in our `esmLoader.ts`.

Introduce `--tsconfig` to specify a single config to be used for all
imported files, instead of looking up tsconfig for each file separately.
Fixes#12829.
This allows a dynamic import of a TS file to be processed by Babel.
For some reason, Playwright used to revert the CJS transforms. However,
ESM loader and transforms are always active, so CJS should be too.
Closes https://github.com/microsoft/playwright/issues/22211
Currently, when the server notifies the UI about changed files, the UI
determines what files to re-run based on an old test list. By listing
tests before that, we make sure that the test list is up-to-date, and
that added tests are included in the next run.
I've also removed the `listChanged` event as discussed in the team sync.
The event isn't used anywhere and fires in exactly the same cases where
`testFilesChanged` fired, so i've folded them into one another. This allowed simplifying `Watcher`.
Introduces an `--only-changed [base ref]` option.
`playwright test --only-changed` filters the test run to only run test
suites that have uncommitted changes.
`playwright test --only-changed=foo` runs only tests that were changed
since commit `foo`.
In pull request CI, this can be used to run changed tests first and fail
fast: `--only-changed=$GITHUB_BASE_REF`.
During local development, it can be used to quickly filter down to the
touched set of tests suites.
In some rare usecases, this can also help to cut down on CI usage for
pull requests. Tread with caution though.
File dependencies are taken into account to ensure that if you touched a
utility file, all relevant tests are still executed.
Closes https://github.com/microsoft/playwright/issues/15075
Broken out of https://github.com/microsoft/playwright/pull/31727 as per
@dgozman's
[request](https://github.com/microsoft/playwright/pull/31727#discussion_r1685793229).
The PR goal is to remove the `suite` argument from the Component
testing's Vite Plugin. `suite` is used to enrich Vite's dependency graph
with information about dependencies between test suites and helper
files. It essentially merges the Vite graph with the
`compilationCache.ts > fileDependencies` graph, and then writes the
result back into `compilationCache.ts > externalDependencies`.
By refactoring this to make the connection on the reading end in
`collectAffectedTestFiles`, we can drop the `suite` parameter.
We didn't yet have a test that depended on the dependency graph being
connected correctly between `fileDependencies` and
`externalDepedencies`, so I've [extended an existing
test](53a539938b)
to capture that.
Previously, only the "actual" attachment was created, pointing to the
file in `test-results`. Now, the "expected" attachment pointing to the
file in `__screenshots__` is also created. This will help any reporters
that would like to know the "expected" path, for example to do a manual
accept/decline of the baseline.
Fixes#30693.
... unless an array of file-system-friendly parts is provided.
Motivation: attachment name is used as a file system path when
downloading attachments, so we keep them fs-friendly.
References #30693.
When used in a terminal, the `list` reporter prints out information
about test steps to help debugging. In non-TTY environments like GitHub
Actions, currently it doesn't.
This PR changes that, so that in non-TTY environments you'll see the
"step end" messages appearing, but not the "step begin" messages. This
is a good middleground, because it helps the user understand test
progress, without being too verbose.
Closes https://github.com/microsoft/playwright/issues/31674
Retaining traces in the following scenarios:
- browser crash;
- manual `browser.close()`;
- implicit `browser.close()` from the `browser` fixture upon test end.
This does not affect the library, where `browser.close()` will not
retain the trace and will close the browser as fast as possible.
