Certain Puppeteer methods do expose the inner browser - e.g.
`browser.version()` depends on the browser we run.
Split out these tests into a vendor-specific test suites.
References #3889
Introduce a `npm run funit` script that runs puppeteer tests
against Puppeteer-Firefox.
Next steps:
- bring Puppeteer-Firefox unique tests to Puppeteer
- skip failing tests and run Puppeteer-Firefox on CI
- work through tests to pass them all with Puppeteer-Firefox
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.
Introduce `//lib/api.js` that declares a list of publicly exposed
classes.
The `//lib/api.js` list superceedes dynamic `helper.tracePublicAPI()` calls
and is used in the following places:
- [ASYNC STACKS]: generate "async stacks" for publicy exposed API in `//index.js`
- [COVERAGE]: move coverage support from `//lib/helper` to `//test/utils`
- [DOCLINT]: get rid of 'exluded classes' hardcoded list
This will help us to re-use our coverage and doclint infrastructure
for Puppeteer-Firefox.
Drive-By: it turns out we didn't run coverage for `SecurityDetails`
class, so we lack coverage for a few methods there. These are excluded
for now, sanity tests will be added in a follow-up.
This patch aligns Puppeteer testing infrastructure with the approach
we use in Puppeteer-Firefox.
This patch:
- makes all tests accept Puppeteer object as a function argument
rather than require it statically. This way we can pass either
Puppeteer or Puppeteer-Firefox to drive tests.
- renames the `puppeteer.spec.js` into `launcher.spec.js`. The
`puppeteer.spec.js` is now the entry point for all cross-browsers
tests.
Tracing is working on a per-browser level, not per-page. In order
to paralellize these tests effectively and properly, each should run
a designated browser.
Drop requirement for matching "origin" and "content-type" headers
in requests and request interceptions. This way javascript redirects
that use form submission start working.
Fix#3684.
ExecutionContext.evaluateHandle accepts arguments that are either
serializable, or JSHandles. A potential confusion is that it *does not*
accept arguments that *contain* JSHandles.
This patch adds a log message warning when it encounters that situation.
Fixes#3562
This patch teaches `page.setContent` to await resources in
the new document.
**NOTE**: This patch changes behavior: currently, `page.setContent`
awaits the `"domcontentloaded"` event; with this patch, we can now await
other lifecycle events, and switched default to the `"load"` event.
The change is justified since current behavior made `page.setContent`
unusable for its main designated usecases, pushing our client
to use [dataURL workaround](https://github.com/GoogleChrome/puppeteer/issues/728#issuecomment-334301491).
Fixes#728
NavigatorWatcher subscribes to Connection to get a `Disconnected` event,
causing us to hit the default max of 10 listeners constraint.
Technically we don't leak anything here and can safely bump
the maxListenersCount to Infinity.
However, we conveniently have `CDPSession`, and
can re-dispatch the event on it and keep the safety check in place.
This adds `page.accessibility.snapshot()`. It serializes and returns the accessibility tree for the page. By default, uninteresting nodes are filtered out of the snapshot.
fixes#2033
This patch enables cookie test. The actual upstream patch
that fixed the issue:
- https://crrev.com/599696 - Headless: support cookie encryption
Fixes#921.
This patch fixes a case in which computeQuadArea calculates the area size correctly, but returns the area as a negative number.
This occurs when DOM.getContentQuads returns quads in a specific order.
E.g. the array: [ { x: 463, y: 68.5 },{ x: 437, y: 68.5 },{ x: 437, y: 94.5 },{ x: 463, y: 94.5 } ] will receive area size of -676.
CSS stylesheets can still be parsed and added events emitted during the CSS.stopRuleUsageTracking call. It needs to be awaited before calling CSS.disable, otherwise the text content of those style sheets will be unavailable.
If nobody forces a layout, CSS coverage is inconsistent. This causes some flakes on the bots. The test in this PR fails 90% of the time on my local machine.
This adds `browser.waitForTarget` and `browserContext.waitForTarget`. It also fixes a flaky test that was incorrectly expecting targets to appear instantly.
This patch:
- adds experimental "transport" option to pptr.connect
- uses "transport" option to make sure Puppeteer-Web works with
Target.exposeDevToolsProtocol
Drive-by: add `browser.target()` to access browser target.
This patch introduces API to manage frame navigations.
As a drive-by, the `response.frame()` method is added as a shortcut
for `response.request().frame()`.
Fixes#2918.
This patch traces all public async methods and wraps them
in a helper method that tags the sync stack trace.
Later on, if the method call throws an exception, we add
a captured stack trace to the original stack trace with the "--ASYNC--"
heading.
An example of a stack trace:
```
Error: net::ERR_ABORTED at http://localhost:8907/empty.html
at navigate (/Users/lushnikov/prog/puppeteer/lib/Page.js:622:37)
at process._tickCallback (internal/process/next_tick.js:68:7)
-- ASYNC --
at Page.<anonymous> (/Users/lushnikov/prog/puppeteer/lib/helper.js:147:27)
at fit (/Users/lushnikov/prog/puppeteer/test/page.spec.js:546:18)
at process._tickCallback (internal/process/next_tick.js:68:7)
```
If referer is passed to the options object its value will be used as the referer instead of the value set by `Page.setExtraHTTPHeaders()`.
This is the correct way to set referer header: otherwise, the `referer` header will override all the document subrequests.
Fixes#3090.
Introduce an API to manage permissions per browser context:
- BrowserContext.overridePermissions(origin, permissions)
- BrowserContext.clearPermissionOverrides()
Fixes#846.
This roll includes:
- https://crrev.com/584293 - DevTools: execute scripts in addScriptToEvaluateOnLoad in order
- https://crrev.com/585630 - DevTools: introduce Browser.grantPermissions
- https://crrev.com/587156 - Revert "[Base] Use background mode for ThreadPriority::BACKGROUND threads (behind feature) (reland)."
The "revert" patch fixes headless functionality on windows.
References #846.
Fixes#3106.
It turned out that almost any usecase requires helper methods to access
DOM inside the ExecutionContext.
Instead of exposing execution contexts as-is, we should introduce
IsolatedWorld as a first-class citizen that will hold execution contexts
inside.
This patch adds a new require, `puppeteer/Errors`, that
holds all the Puppeteer-specific error classes.
Currently, the only custom error class we use is `TimeoutError`. We'll
expand in future with `CrashError` and some others.
Fixes#1694.
This allows us:
- dogfood browser contexts the way we want them to be used
- simplifies the dance around service workers / cookies setting up and tier down.
This changes sendCharacter to use document.execCommand instead of sending a `'char'` event from the protocol. This is more aligned with how input would come in from emoji keyboards, and removes the 3ish byte limit on characters that can be sent which prevented larger emoji from being rendered correctly.
Emoji will still fail to type correctly if typing them into an iframe that is in shadow dom.
fixes#1096
This patch rolls Chromium to r579032. The patch includes:
- https://crrev.com/577366 - DevTools: report redirect responses only if response interception is enabled
- https://crrev.com/577212 - DevTools: intercept requests resulting from redirects
- https://crrev.com/578934 - DevTools: Add a protocol method to insertText
Interception Logic in DevTools protocol has changed regarding redirects;
this patch migrates interceptions to dispatch "request" events based on
requestWillBeSent event.
I have seen some flaky test failures where it would be nice to have run the tests with `DEBUG=puppeteer:error`. Instead of always running tests like that, I am redirecting `debugError` to the output category of the test. This is the same thing that we do for Chromium's stderr.
As a drive-by, I added an additional `debugError` where we were usually a try..finally pattern.
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
Chrome DevTools shows anonymous scripts with yellow background and names
them with `debugger://VM<scriptId>` prefix.
This patch starts reporting the same debugger:// urls for anonymous
scripts in puppeteer's JS coverage. This might simplify debugging, e.g.
using `debugger;` statement to reveal the script in DevTools and later
matching it against the one in the coverage.
This patch:
- simplifies test reusing the `offscreenbuttons.html` asset
- aligns IntersectionObserver usage with the one we have for
`ElementHandle._scrollIntoViewIfNeeded`.
This patch adds `reportAnonymousScripts` option to the `coverage.startJSCoverage` method. With this option, anonymous scripts are reported as well.
Fixes#2777
EmualationManager used to be injecting touch hooks to properly
support touch emulation.
However, these are no longer necessary, since https://crbug.com/133915
is long fixed.
Originally, we use `Element.scrollIntoViewIfNeeded` to make sure
button is on screen before trying to click it.
However, `Element.scrollIntoViewIfNeeded` doesn't work in certain
scenarios, e.g. when element is partially visible and horizontal
scrolling is required to make it fully visible.
This patch polyfills `element.scrollIntoViewIfNeeded` using
IntersectionObserver and `Element.scrollIntoView`.
Fixes#2804.
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.
This patch eliminates a common race condition with WaitTask, that
happens when predicate function gets resolved right before the execution
context gets destroyed.
This situation results in a "Cannot find context with specified id undefined"
exception.
Credits go to @jakub300 for his wonderful [investigation](https://github.com/GoogleChrome/puppeteer/issues/1325#issuecomment-395472092).
Fixes#1325.
`Data.prototype.toString` may return non-ASCII characters, which aren't accepted by `setHeader`.
E.g., on Russian locale, it might look like this:
```
> new Date().toString()
'Thu Jun 14 2018 13:11:50 GMT+0300 (Финляндия (лето))'
```
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.
This patch disables OOPIF by default.
**NOTE**: this is a temporary bandaid for the time we're crafting
the full-fledged support for site isolation over DevTools protocol.
References #2548.
It's impossible to launch chromium without initial page.
This patch makes sure that `puppeteer.launch()` always returns a browser
with at least one page user can connect to.
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.
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.
References #2632
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.
References #2524
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 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.
