12bc1e1a62 feat(coverage): add an option to collect coverage of anonymous scripts (#2796)

73f9c48081 feat: nicer protocol error messages (#2742)
This patch:
- stops appending `undefined` to our protocol messages unnecessarily.
- rewrites `Cannot find execution context id` to `Execution context was destroyed, most likely because of a navigation.` when it occurs from a Puppeteer ExecutionContext. The error message is left alone if it occurs via a CDPSession.

chore: stop using console.assert everywhere (#2646)
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.

93fe2b57d6 feat(Page): introduce workers (#2560)
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.

8c54f41552 chore(types): generate a d.ts file for protocol types (#2325)
This uses the `/json/protocol` endpoint to generate type definitions for the protocol.

Currently it is lacking protocol events and commands, but I will add those later.

feat(ExecutionContext): introduce ExecutionContext.frame() (#1972)
This patch introduces ExecutionContext.frame() that returns Frame
associated with this Execution Context.

This allows to associate console messages with the originating frame,
if any.

fix(Frame): postpone evaluations until execution context gets created (#1415)
In Blink, frames don't necesserily have execution context all the time.
DevTools Protocol precisely reports this situation, which results in
Puppeteer's frame.executionContext() being null occasionally.

However, from puppeteer point of view every frame will have at least a
default executions context, sooner or later:

- frame's execution context might be created naturally to run frame's
  javascript
- if frame has no javascript, devtools protocol will issue execution
  context creation

This patch builds up on this assumption and makes frame.executionContext()
to be a promise.
As a result, all the evaluations await for the execution context to be created first.

Fixes #827, #1325

BREAKING CHANGE: this patch changes frame.executionContext() method to return a promise.
To migrate onto a new behavior, await the context first before using it.

5c92ba222a fix(page.evaluate): jsonValue should ignore toJSON property (#1098)
Currently, JSHandle.jsonValue() is implemented as in-page JSON.stringify
call and consequent JSON.parse in node. This approach proved to be
unfortunate for automation purposes: if page author overrode the
Object.prototype.toJSON method, then it's harder for puppeteer to
interact with the page.

This patch switches JSHandle.jsonValue to use protocol serialization
that ignores toJSON property. THis also changes the `page.evaluate`
behavior since it is based on JSHandle.jsonValue().

Fixes #1003.

BREAKING CHANGE:
`page.evaluate` no longer calls toJSON when generating return value.
For the old behavior, do JSON.parse/JSON.stringify manually:

```js
const json = JSON.parse(await page.evaluate(() => JSON.stringify(obj)));
```

e59172de83 chore: Use Typescript to lint JSDoc annotations (#986)
This patch starts using typescript to lint JSDoc annotations.

Note: this uses typescript's bleeding edge. We should migrate to stable once
it has all the necessary bugfixes.

0d0f9b7984 feat(JSHandles): introduce JSHandles (#943)
This patch:
- introduces ExecutionContext class that incapsulates javascript
  execution context. An examples of execution contexts are workers and
  frames
- introduces JSHandle that holds a references to the javascript
  object in ExecutionContext
- inherits ElementHandle from JSHandle

Fixes #382.
