* feat: Set which browser to launch via PUPPETEER_PRODUCT
This change introduces a PUPPETEER_PRODUCT environment
variable as a first step toward using Puppeteer with
many different browsers. Setting PUPPETEER_PRODUCT=firefox, for
example, enables Firefox-specific Launcher settings.
The state is also exposed as `puppeteer.product` in the API
to support adding other product-specific behaviour as needed.
The bulk of the change is a refactoring in Launcher
to decouple generic browser start-up from product-specific
configuration.
Respecting the puppeteer-core restriction for PUPPETEER_
environment variables, lazily instantiate the Launcher
based on a `product` Puppeteer.launch option, if available.
* test: Distinguish Juggler unit tests from Firefox
The funit script is renamed to fjunit (j for Juggler, which is
used only by the experimental puppeteer-firefox package.
In contrast, the funit script now refers to running Puppeteer
unit tests against the main puppeteer package with Firefox.
To do so with Firefox Nightly, run:
`BINARY=path/to/firefox npm run funit`
A number of changes in this patch make it easier to run
Puppeteer unit tests in Mozilla's CI.
This patch:
- updates Flakiness Dashboard format to define version per-build
and to pass COMMIT information
- drops the README.md generation - we'll move on to a designated flakiness
dashboard viewer
We used to track API Coverage for public events, but this was regressed in the refactoring that
introduced `//lib/Events.js`.
This patch:
- Brings back API Coverage for events
- Combines all coverage-generated tests into a single one. This way
we can generate less data for flakiness dashboard.
This patch introduces a dashboard that records test results and
uploads them to https://github.com/aslushnikov/puppeteer-flakiness-dashboard
Since many bots might push results in parallel, each bot pushes
results to its own git branch.
FlakinessDashboard also generates a simple README.md with a flakiness
summary. If this proves to be not enough, we can build a website that
fetches flakiness data and renders it nicely.
This patch adds new TestRunner options:
- `disableTimeoutWhenInspectorIsEnabled` - disable test timeout if
testrunner detects enabled inspector.
- `breakOnFailure` - if testrunner should terminate test running on
first test failure
Firefox used to have a bug that prevented adding iframes with the
same URL as main frame. In this case, we used the EMPTY_PAGE2
so that it doesn't clash with top-level EMPTY_PAGE.
The bug seems to be fixed after we rolled onto a fresh Firefox;
there's no more need for this test asset.
This patch:
- introduces new testRunner methods `addTestDSL` and `addSuiteDSL`
to add annotated test / suite.
- introduces new test/suite declaration methods: `it_fails_ffox` and
`describe_fails_ffox`. These are equal to `it`/`describe` for chromium
tests and to `xit`/`xdescribe` for firefox.
- marks all unsupported tests with `it_fails_ffox`
- adds a new command-line flag `'--firefox-status'` to `//test/test.js`.
This flag dumps current amount of tests that are intentionally skipped
for Firefox.
End goal: get rid of all `it_fails_ffox` and `describe_fails_ffox`
tests.
Drive-By: remove cookie tests "afterEach" hook that was removing
cookies - it's not needed any more since every test is run in a
designated browser context.

This patch:
- adds support to `FFOX` env variable for Puppeteer testsuite
- install Firefox preferences when running tests with custom firefox
executable
References #3889
This patch:
- changes Puppeteer-Firefox plumbing of defaultBrowserOptions to align
with the way we do it for Puppeteer.
- plumbs puppeeteer-dependent Errors and DeviceDescriptors down to every
test.
- unifies a few tests between Puppeteer-Firefox and Puppeteer.
**Note:** in future, we should expose errors as `puppeteer.errors` and
device descriptors as `puppeteer.devices` to make it easy to pass around
Puppeteer/Puppeteer-Firefox instance.
References #3889.
Introduce a `npm run funit` script that runs puppeteer tests
against Puppeteer-Firefox.
Next steps:
- bring Puppeteer-Firefox unique tests to Puppeteer
- skip failing tests and run Puppeteer-Firefox on CI
- work through tests to pass them all with Puppeteer-Firefox
Introduce `//lib/api.js` that declares a list of publicly exposed
classes.
The `//lib/api.js` list superceedes dynamic `helper.tracePublicAPI()` calls
and is used in the following places:
- [ASYNC STACKS]: generate "async stacks" for publicy exposed API in `//index.js`
- [COVERAGE]: move coverage support from `//lib/helper` to `//test/utils`
- [DOCLINT]: get rid of 'exluded classes' hardcoded list
This will help us to re-use our coverage and doclint infrastructure
for Puppeteer-Firefox.
Drive-By: it turns out we didn't run coverage for `SecurityDetails`
class, so we lack coverage for a few methods there. These are excluded
for now, sanity tests will be added in a follow-up.
This patch aligns Puppeteer testing infrastructure with the approach
we use in Puppeteer-Firefox.
This patch:
- makes all tests accept Puppeteer object as a function argument
rather than require it statically. This way we can pass either
Puppeteer or Puppeteer-Firefox to drive tests.
- renames the `puppeteer.spec.js` into `launcher.spec.js`. The
`puppeteer.spec.js` is now the entry point for all cross-browsers
tests.
Tracing is working on a per-browser level, not per-page. In order
to paralellize these tests effectively and properly, each should run
a designated browser.
This adds `page.accessibility.snapshot()`. It serializes and returns the accessibility tree for the page. By default, uninteresting nodes are filtered out of the snapshot.
fixes#2033
This patch adds a new require, `puppeteer/Errors`, that
holds all the Puppeteer-specific error classes.
Currently, the only custom error class we use is `TimeoutError`. We'll
expand in future with `CrashError` and some others.
Fixes#1694.
This allows us:
- dogfood browser contexts the way we want them to be used
- simplifies the dance around service workers / cookies setting up and tier down.
I have seen some flaky test failures where it would be nice to have run the tests with `DEBUG=puppeteer:error`. Instead of always running tests like that, I am redirecting `debugError` to the output category of the test. This is the same thing that we do for Chromium's stderr.
As a drive-by, I added an additional `debugError` where we were usually a try..finally pattern.
This patch:
- adds `worker.evaluate` and `worker.evaluateHandle` methods as a shortcut to their execution context equivalents.
- makes the error messages a bit nicer when interacting with a closed worker (as opposed to a closed page).
- moves the worker tests into their own spec file.
Since Node 10, `console.assert` no longer throws an AssertionError.
(This is generally good since it aligns Node.js with Browsers.)
This patch migrates all usages of `console.assert` in our codebase.
- All the `lib/` and testing code is migrated onto a handmade `assert`
function. This is to make Puppeteer transpilation / bundling easier.
- All the tooling is switched to use Node's `assert` module.
Fixes#2547.
This patch allows logging the output of the Chromium process to be enabled in tests by passing in the environment variable `DUMPIO=true`.
Additionally, the `stderr` of the Chromium process will always be logged in the the "Output" section of failing page tests.
This patch introduces Browser Contexts and methods to manage them:
- `browser.createIncognitoBrowserContext()` - to create new incognito
context
- `browser.browserContext()` - to get all existing contexts
- `browserContext.dispose()` - to dispose incognito context.
Fixes#85.
This patch fixes puppeteer navigation primitives to work with
same-document navigation.
Same-document navigation happens when document's URL is changed,
but document instance is not re-created. Some common scenarios
for same-document navigation are:
- History API
- anchor navigation
With this patch:
- pptr starts dispatching `framenavigated` event when frame's URL gets
changed due to same-document navigation
- `page.waitForNavigation` now works with same-document navigation
- `page.goBack()` and `page.goForward()` are handled correctly.
Fixes#257.
