We now commit protocol.ts files during the roll.
New utils/roll_browser.js helps with that.
This makes our installation very shallow:
- build installer;
- download browsers.
When innerWindow is restored from the history state, we do not receive
content-document-global-created notification, but would still like to know
that window is now using a different inner window to reset the state.
This introduces a new notification juggler-dom-window-reused.
At the same time, goBack()/goForward() sometimes do not initiate
navigation synchronously, so our check for pendingNaivgationId() does
not work. Instead, we rely on canGoBack, and assume that client will
not need the navigationId synchronously.
This patch:
- makes environment a simple class with optional methods `beforeEach`, `afterEach`, `beforeAll`, `afterAll`, `globalSetup` and `globalTeardown`
- removes capability to have multiple hooks of the same name inside suite
- removes default environment for test. (`dit` now adds a `TraceTestEnvironment` to the test)
- extracts all environments that we use in our tests in `//test/environments.js`
Downsides:
- we no longer know hook locations for the environments. This, however, should not be a big deal since stack traces (if any) will still point into it.
- this also regresses hook locations for suites for simplicity. We can get them back, but it shouldn't be pressing since we now have only one hook of each kind in every suite.
Firefox and WebKit require native promises to provide awaitPromise
functionality. When the Promise is overwritten, all evaluations
in the main world produce wrong Promise, so we wrap with async
function to get a native promise instead.
We now query selector and take textContent synchronously. This
avoids any issues with async processing: node being recycled,
detached, etc.
More methods will follow with the same atomic pattern.
Drive-by: fixed selector engine names being sometimes case-sensitive
and sometimes not.
We currently return undefined whenever we had an error trying
return the evaluation result by error. The most common error
is "execution context destroyed".
This produces very unexpected undefined from methods that do not
ever expect undefined. Instead, we should throw because we were
not able to return the result.
