The page.waitForFunction method allows to wait for a general predicate.
The predicate will be continiously polled for in page, until
it either returns true or the timeout happens.
The polling parameter could be one of the following:
- 'raf' - to poll on every animation frame
- 'mutation' - to poll on every dom mutation
- <number> - to poll every X milliseconds

This patch:
- implements a basic public API coverage based on 'helper.tracePublicAPI' methods
- adds `npm run coverage` command which reports coverage after running all of the unit tests
References #50.
This patch:
- removes Body.arrayBuffer. This method is redundant since there's
already a Body.buffer() method
- removes Body.bodyUsed getter.
References #106
This patch:
- renames page.setHTTPHeaders into page.setExtraHTTPHeaders
- starts using Map instead of Object to align with other headers
arguments
Fixes#112.
This patch improves on page.evaluate to accept a string.
The string can have a trailing '//# sourceURL=' comment which would
name the evaluation to make stacks beautiful.
In order to make sourceURL comments possible, this patch:
- removes wrapping of the client function into `Promise.resolve()`
- stops passing `awaitPromise` parameter to `Runtime.evaluate`
- starts to await promise via the `Runtime.awaitPromise` if the return type of the evaluation
is promise
closes#118
This patch renames page.evaluateOnInitialized into
page.evaluateOnNewDocument to better align with the protocol and with
what the method is actually doing.
Fixes#119.
Refactor Frame.waitForSelector to make room for Frame.waitForFunction
implementation.
This patch:
- removes AwaitedElement class which proved to be confusing, and
introduces a more straight-forward WaitTask.
- refactors the mutation observer to return true in case of successful
waiting or false in case of timeout.
References #91
This patch:
- introduces helper.addEventListener/helper.removeEventListeners
to simplify event management
- moves NavigatorWatchdog over to the helper.addEventListener to
stop leaking event listeners
This patch:
- adds Mouse class which holds mouse state and implements mouse primitives,
such as moving, button down and button up.
- implements high-level mouse api, such as `page.click` and `page.hover`.
References #40, References #89
This patch:
- introduces page.waitForSelector to wait for the selector to appear
- introduces polymorphic page.waitFor method, which accepts
either string (and in this case is a shortcut for page.waitForSelector)
or number (and in this case it's a promisified timeout).
References #91.
This patch implements timeout option for page.waitFor. The function
will throw if the selector doesn't appear during timeout milliseconds
of waittime.
References #89, #91.
This patch adds a 'visible' option to the Page.waitFor method, making
it possible to wait for the element to become actually visible.
References #89, #91.
This patch:
- gets rid of `page.emulate` and `page.emulatedDevices`
methods. Instead, it is suggested to use `page.setViewport()`
and `page.setUserAgent()` methods.
- moves DeviceDescriptors to the top level of the puppeteer so that
it is convenient to require them.
- improves on documentation to describe the suggested emulation
approach.

The unit testing on mac is unreliable, making the last tests to hang.
This seems to be related to the upstream bug: crbug.com/741689
For now, this patch restarts the browser in the middle of unit testing.
This should be reverted once the upstream is fixed.
References #100.
Currently, it's impossible to do screenshots in parallel.
This patch:
- makes all screenshot tasks sequential inside one browser
- starts activating target before taking screenshot
- adds a test to make sure it's possible to take screenshots across
tabs
- starts waiting for a proper page closing after each test. This might
finally solve the ECONNRESET issues in tests.
References #89
This patch:
- resolves pending callbacks in connection once it gets closed
- fixes one of Page.screenshot() tests to wait for all the screenshots
- starts handling ECONNRESET error in test server to avoid throwing with no
good reason
This patch introduces Page.waitForNavigation which allows to wait
for render-initiated navigation.
This patch also does a nice refactoring, replacing Navigator with NavigatorWatcher which
is not a part of a page state.
References #89
This patch:
- renames Page.printToPDF into page.pdf
- adds a 'path' option to the page.pdf options instead of a separate
`filePath` parameter
- improves on the documentation for the `page.pdf`
References #39.
