This patch makes it so that we only refer to specific Node.js versions like `10.19.0` when we really mean to use exactly that version. Usually we just want to test the latest version in a major range, e.g. `10`.
It also adds an inline comment that makes it easier to update the versions across the file in the future (e.g. when Node.js 10 goes EOL in April 2021).
Issue: #6561
* chore: run unit tests on node 10.15
We saw in https://github.com/puppeteer/puppeteer/issues/6548 that the
`fs.promises` module was experimental in Node <10.17 and as such we
introduced issues for users on 10.15.
Until we can drop Node v10 (it's EOL is 30-04-20201
https://github.com/nodejs/Release#release-schedule) we should run our
tests on an old Node 10 to avoid regressing in this area.
* chore: helper for importing fs safely
* chore(agnostification): common/helper.ts
The `readProtocolStream` method uses `fs` only if you want to write to a
file. So we gate at the start of the function and ensure that if we got
given a path we are not in a Node environment.
They are generating a lot of noise in PRs. This commit removes them from git, but updates CI to generate them - to ensure there are no errors when generating the new documentation.
Further commits will:
1. Introduce linting to enforce methods are documented.
2. Generate previews of the new docs via GitHub actions or similar.
* chore: Use devtools-protocol package
Rather than maintain our own protocol we can instead use the devtools-protocol package and pin it to the version of Chromium that Puppeteer is shipping with.
The only changes are naming changes between the bespoke protocol that Puppeteer created and the devtools-protocol one.
Now the async hooks helper is gone api.ts was only used by the coverage
tools and by doclint.
DocLint is nearing the end of its lifespan with the TSDoc work, so I
focused on how best to define a list of modules for the coverage
tooling. They define an object of classes, and the path to that module.
They need the full path because we also check if the module exports any
events that need to be emitted - the coverage tool asserts that the
emitting of those events is also tested.
It's not _great_ that DocLint relies on a constant defined in the
coverage utils, but it should only be this way for a short period of
time and no one is actively working on DocLint (bar the effort to remove
it) so I don't think this is worth worrying about.
This change also broke the DocLint tests; based on the fact that DocLint is on its way out it doesn't feel worth fixing the tests, so this commit also removes them.
* chore: Don't store revisions in `package.json`
It's quite messy to have to require the `package.json` file in multiple
places purely to find out what revision of a given browser we want to
use. We can also achieve better type safety by placing it in an actual
source file.
This commit makes that change and also tidies up our reliance on
`package.json` within the source code generally; we now only use it to
find the location of the Puppeteer root such that we know where to
install downloaded browsers to.
To avoid using `package.json` to parse the name of the module, we also
now explicitly have an entry point for the Puppeteer module and the
Puppeter Core module. This will make it easier in the future to ship
less code as part of core (e.g. core never needs to download a browser,
so why ship that code?). Core can also then not have any revisions based
info contained in it.
The test install script has also been updated to ensure that
puppeteer-core can be installed correctly too.
Finally, the `install` script has been moved to TypeScript for nicer
typechecking and safety. The functionality of it has not changed.
* chore: ensure new-docs are up to date
This adds a Travis check that if we re-generate the docs we get the
exact output (by checking if the Git tree is dirty).
We do the dirty check by using `git status --porcelain`, seeing how many
lines that outputs, and using that as the exit code (taking only the
first 255 lines to avoid invalid exit codes). `--porcelain` makes the
output be empty if the repo is not dirty in anyway which translates into
an exit code of 0.
We can't use `git diff-index --quiet HEAD` as it exits with 0 if there are
untracked files in the repo but we want that to cause a failure.
This script generated an `index.d.ts` file but that file was never
commited to git nor included in Puppeteer when we ship. As of right now
people who want TS types can install from the DefinitelyTyped repo and
we are working on shipping types from Puppeteer itself.
Therefore this script is not adding any value and can be removed.
* chore: fix invalid SSL assertion on Catalina
The error Chrome gives with an invalid cert changes between older Mac
versions and Catalina as detailed here:
https://support.google.com/chrome/thread/18125056?hl=en.
This PR changes Travis to run Catalina (and we think most devs run up to
date OS versions) so this fix ensures the test behaviour is consistent
locally and on Travis.
For those on older Mac versions I've left a comment by the tests to
hopefully save them debugging!

* 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.

* chore: enforce src/protocol.d.ts is in sync
On CI we run `npm run compare-protocol-d-ts` which checks that the file
on disk is up to date with the protocol we fetch from the browser.

* Increased the timeout to a flat 25 second for every build because we
still see the odd, non-reproducible timeout on a variety of machines.
* Removed an extraneous `npm run test-install` which meant we did that
check twice on each CI run.
* chore: add test for npm package installing correctly
This command packs up the module and installs it again to check we're
correctly bundling everything we need to allow users to do a fresh
install.
* install realpath
* chore: migrate `src/USKeyboardLayout` to typescript
Don't think we need to expose the interface type for the keycodes so
I've left it local for now.
* retry windows unit tests
* 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.
Our CI build has been incredibly flaky across all three of our current CIs:
* Appveyor: Chromium + Windows
* Travis: Firefox + Linux, Chromium + Linux
* Cirrus: Chromium + Linux, Chromium + Mac
Legitimate issues and errors have been missed because it's expected that the CI is red and therefore it's not seen as an issue when a PR's build fails.
We should have a build that covers the full combo of browsers and operating systems but it's more important to have a consistent, reliable green build where failures are genuine. So this commit strips our CI back to Chromium on Linux on Travis, and nothing more. Once this is stable we will expand out into more operating systems and bring back Firefox, too.
* chore: update relevant Node.js versions from 8 to 10
* chore: remove node6 and node8 folders from puppeteer-firefox ci
* fix: loosen definition for proc.stdio
* fix: update typescript version used in npm run test-types
* 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.
Apparently all the issues happen because we switched from travis.org
to travis.com. So this enctryption key was generated with:
```sh
travis encrypt <KEY> --add deploy.api_key --com --repo
GoogleChrome/puppeteer
```
This patch:
- adds "browser" field to the package.json with default
bundling options.
- introduces "bundle" and "unit-bundle" commands to
create bundle and test bundle
- starts running bundle tests on Travis Node 8 bots
Fixes#2374.
