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.
These getters are introduced as a more convenient substitute for
a `require('puppeteer/Errors')` and
`require('puppeteer/DeviceDescriptors')`.
This way we can make cross-browser story nicer - a single require
of `puppeteer` or `puppeteer-firefox` fully defines Puppeteer
environment.
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 aligns all Puppeteer tests so that they never throw the
"UnhandledPromiseRejection" when run with Puppeteer-Firefox.
With this patch, the `npm run funit` passes 275 of 460 Puppeteer tests.

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.

Method `page.setDefaultTimeout` overrides default 30 seconds timeout
for all `page.waitFor*` methods, including navigation and waiting
for selectors.
Fix#3319.
This patch starts executing frame.waitForSelector and frame.waitForXPath
in secondary world. As a result, websites that mutate page global
context (e.g. removing global MutationObserver) don't break Puppeteer's
behavior.
Fixes#609
`page.waitForSelector` should return `null` if waiting for `hidden:
true` and there's no matching node in DOM.
Before this patch, `page.waitForSelector` would return some JSHandle
pointing to boolean value.
