* Warn when given unsupported product name.
Fixes#5844.
This change means when a user launches Puppeteer with a product name
that is not supported (which at the time of this commit means it's not
`firefox` or `chrome) we will warn them about it.
Decided on just a warning vs an error because the current behaviour is
that we fallback to launching Chrome and I don't think this warrants a
breaking change.
* chore: update how we track coverage during unit tests
The old method of tracking coverage was causing issues. If a test failed
on CI, that test's failure would be lost because the test failing would
in turn cause the coverage to fail, but the `process.exit(1)` in the
coverage code caused Mocha to not output anything useful.
Instead the coverage checker now:
* tracks the coverage in memory in a Map (this hasn't changed)
* after all tests, writes that to disk in test/coverage.json (which is
gitignored)
* we then run a single Mocha test that asserts every method was called.
This means if the test run fails, the build will fail and give the error
about that test run, and that output won't be lost when the coverage
then fails too.

The codebase was incredibly inconsistent with the use of spacing around
curly braces, e.g.:
```
// this?
const a = {b: 1}
// or?
const a = { b: 1 }
```
This extended into import statements also. Google's styleguide is no
spacing, so we're going with that.
* chore: Add Windows to Travis
This commit runs the unit tests on Windows.
There are two tests failing on Windows that we skip.
I spoke to Mathias B and we agreed to
defer debugging this for now in favour of getting tests running on
Windows. But we didn't want to ignore it forever, hence giving the test
a date at which it will start to fail.
This commit updates all the non-Puppeteer unit tests to run using Mocha and then deletes the custom test runner framework from this repository. The documentation has also been updated.
Rather than maintain our own test runner we should instead lean on the community and use Mocha which is very popular and also our test runner of choice in DevTools too.
Note that this commit doesn't remove the TestRunner source as it's still used for other unit tests, but they will be updated in a future PR and then we can remove the TestRunner.
The main bulk of this PR is updating the tests as the old TestRunner passed in contextual data via the `it` function callback whereas Mocha does not, so we introduce some helpers for the tests to make it easier.
See the large code comment in the diff for a full explanation but we can't rely on the functions being referentially equivalent so instead we test the behaviour in duplicate tests across the deprecated method and the new method.
They fail because cookies in Firefox return a `sameSite` key which the tests don't expect.
This is a solution that at least gets the Travis Firefox build (hopefully!) green again. Longer term it'd be great to allow the assertion to change based on the browser, rather than skip these tests entirely.
Rather than use our own custom expect library, we can use expect from npm [1], which has an API almost identical to the one Puppeteer has, but with more options, better diffing, and is used by many in the community as it's the default assertions library that comes with Jest.
It's also thoroughly documented [2].

* (feat) Add option to fetch Firefox Nightly
Add Firefox support to BrowserFetcher and the install script.
By default, the latest Firefox Nightly is downloaded
directly from archive.mozilla.org (dmg, tar.bz2 and zip)
This also required changes that impact `puppeteer.launch()`
and `puppeteer.executablePath()`

* 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.
Node.js v6 was end-of-life'd in April, 2019, with AWS Lambda prohibiting updaets to the Node.js v6 runtime since June 30, 2019.
This makes it quite safe for us to remove the Node 6 support from the repository.
We'd like to pass an abortion signal inside Helper.waitForEvent in order to interrupt it when browser/page closes. Several approaches have been considered:
1. Pass CDPSession instance as a another parameter to the helper method and listen to Disconnected event on it. It would introduce undesired dependency on the session object.
2. Listen to the CDPSession closure at the call sites (e.g. waitForRequest) and pass an abortion promise which would be fulfilled when such event is fired. The listeners would have to be removed from the session on successful completion of waitForEvent so we'd have to pass some kind of DisposablePromise which would be disposed during cleanup. Such parameter looked somewhat hairy.
3. Create DisconnectPromise on CDPSession. One potential risk with that is all chained promises would hang around until the event is fired which might inadvertently cause memory leaks. On the other hand, adding such promise to Promise.race will remove dependency as soon as the race is finished. So this is the approach we're taking with one tweak: the promise is created locally inside Page.
Ideally the disconnectPromise would throw when the session is closed but it may lead to uncaught promise errors if all chained promises are resolved, to avoid that the promise is resolved with an Error and Helper.waitForEvent throws it later.
Fix#4733
Our magical node6 transpiler can't handle object spreads :(
Drive-by: use "includes" instead of "startsWith" for devtools URL
since I remember that it used to be "chrome-devtools://", and somehow
I saw it as "devtools://" somewhere.
This roll includes:
- https://crrev.com/681997 - Turn on default SiteInstance by default.
The SiteInstance by default was breaking "devtools: true" option, so
there's a new feature we disable now by default.
This keeps pressuring us towards OOPIF support since that's an
inevitable future.
`testRunner.run()` might have 4 different outcomes:
- `ok` - all non-skipped tests passed
- `failed` - some tests failed or timed out
- `terminated` - process received SIGHUP/SIGINT while testrunner was running tests. This happens on CI's under certain circumstances, e.g. when
VM is getting re-scheduled.
- `crashed` - testrunner terminated test execution due to either `UnhandledPromiseRejection` or
some of the hooks (`beforeEach/afterEach/beforeAll/afterAll`) failures.
As an implication, there are 2 new test results: `terminated` and `crashed`.
All possible test results are:
- `ok` - test worked just fine
- `skipped` - test was skipped with `xit`
- `timedout` - test timed out
- `failed` - test threw an exception while running
- `terminated` - testrunner got terminated while running this test
- `crashed` - some `beforeEach` / `afterEach` hook corresponding to this
test timed out of threw an exception.
This patch changes a few parts of the testrunner API:
- `testRunner.run()` now returns an object `{result: string,
terminationError?: Error, terminationMessage?: string}`
- the same object is dispatched via `testRunner.on('finished')` event
- `testRunner.on('terminated')` got removed
- tests now might have `crashed` and `terminated` results
- `testRunner.on('teststarted')` dispatched before running all related
`beforeEach` hooks, and `testRunner.on('testfinished')` dispatched after
running all related `afterEach` hooks.
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
