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.
Page subtargets (e.g. out-of-process iframes and others) sometimes
die before we send the 'detach' command.
This is harmless to us, but we shouldn't have an unhandled promise
rejection in this case.

This patch drops the markdown-toc module and instead rolls out
our own simple markdown table-of-contents generator.
As a side effect, it fixes links to `page.$` and `page.$$`.
Some of the worker tests were failing on the bots. After investigating, I found one race in the test, and one race upstream in Chromium which I filed upstream as https://crbug.com/846099. But I added a small hack here as a temporary workaround.

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.
Scrollbars look different on different platforms, so must be made invisible in tests. As a drive-by, xdescribe was broken with the new test runner.

Previously protocol.d.ts was generated on `npm run tsc`. This was inconvenient because it meant that vscode checking was wrong until type checking was run manually, and was inefficient because it necessarily regenerated the types even if no new Chromium was downloaded. This patch generates the types when npm install is run from the github checkout, assuming a new Chromium revision was downloaded.
Docs about `page.$$eval` and `frame.$$eval` are not accurate and might be confusing. `document.querySelectorAll` returns `NodeList`, while `frame.$$eval` is actually doing `Array.from(querySelectorAll(selector))`, which actually returns an array.
This makes things this possible:
`await page.$$eval('div', divs => divs.map...)`
This patch fixes docs to mention that $$eval is actually performing:
`Array.from(querySelectorAll(selector))`
Which will let the user understand that the element he receives is an array, and not a NodeList.
This adds `page.workers()`, and two events `workercreated` and `workerdestroyed`. It also forwards logs from a worker into the page `console` event.
Only dedicated workers are supported for now, ServiceWorkers will probably work differently because they aren't necessarily associated with a single page.
Fixes#2350.
This patch starts explicitly passing allowed options to the `Browser`
class. This, for example, makes it impossible to pass `appMode` as
an option to the `pptr.connect`.
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.
Today, `page.close()` method doesn't run page's beforeunload listeners.
This way users can be sure that `page.close()` actually closes the
page.
This patch adds an optional `runBeforeUnload` option to the
`page.close()` method that would run beforeunload listeners. Note:
running beforeunload handlers might cancel page closing.
Fixes#2386.
