When an evaluation causes a navigation, for example:
```js
await page.evaluate(() => window.reload());
```
sometimes we process the ExecutionContextDestroyed event before the ack from the evaluate. When we do get the ack from the evaluate, we try to build a JSHandle for it, and try to find the execution by id. But it is gone, and we throw an error. This patch switches createJSHandle to accept an ExecutionContext instead of just an id.
This bug was making the test `should throw a nice error after a navigation` flaky.
In accordance with its declared type, `Map<string, Function>`.
Currently, it is used as a plain old JS object. The compiler marks this
usage as an error when `noImplicitAny: true`. This change switches to
use the appropriate Map methods `has/get/set`.
Fixes#3000
Unfortunately, disabling javascript in page prevents any microtasks
to be executed even from puppeteer-originating javascript. As a
result, the IntersectionObserver hack we use to conditionally
scroll into view doesn't work.
To workaround this, we start always scrolling before clicking if
page's javascript is disabled.
Fixes#2898
This patch:
- adds `worker.evaluate` and `worker.evaluateHandle` methods as a shortcut to their execution context equivalents.
- makes the error messages a bit nicer when interacting with a closed worker (as opposed to a closed page).
- moves the worker tests into their own spec file.
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 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.
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.
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.
This patch introduces a new `pipe` option to the launcher to connect over a pipe.
In certain environments, exposing web socket for remote debugging is a security risk.
Pipe connection eliminates this risk.
This patch:
- introduces `page.waitForXPath` method
- introduces `frame.waitForXPath` method
- amends `page.waitFor` to treat strings that start with `//` as xpath queries.
Fixes#1757.
feat: expose raw devtools protocol connection
This patch introduces `target.createCDPSession` method that
allows directly communicating with the target over the
Chrome DevTools Protocol.
Fixes#31.
This patch introduces a new `page.coverage` namespace with two methods:
- `page.coverage.startJSCoverage` to initiate JavaScript coverage
recording
- `page.coverage.stopJSCoverage` to stop JavaScript coverage and get
results
The patch converts all the getters in the codebase into the methods.
For example, the `request.url` getter becomes the `request.url()`
method.
This is done in order to unify the API and make it more predictable.
The general rule for all further changes would be:
- there are no getters/fields exposed in the api
- the only exceptions are "namespaces", e.g. `page.keyboard`
Fixes#280.
BREAKING CHANGE:
This patch ditches getters and replaces them with methods throughout
the API. The following methods were added instead of the fields:
- dialog.type()
- consoleMessage.args()
- consoleMessage.text()
- consoleMessage.type()
- request.headers()
- request.method()
- request.postData()
- request.resourceType()
- request.url()
- response.headers()
- response.ok()
- response.status()
- response.url()
This refactors the page.content and page.setContent methods to be defined on the Frame class. This allows access from the Page still but also on all frames.
Fixes#754
