We used to sort based on workerHash, and that changes depending on
the exact worker fixtures list. Now we replace workerHash with
an ordinal when constructing the TestGroup list to preserve the
natural order.
- `TestResult.startTime`
- `Suite.location` is optional now
- `Test.status()` renamed to `Test.outcome()` to differentiate against a
`Test.expectedStatus` and `TestResult.status` of the different type.
This makes our suite structure the following:
```
Root(title='') > Project(title=projectName) > File(title=relativeFilePath) > ...suites > test
```
Removed `fullTitle()` because it is not used directly by anyone.
Default reporters now report each test as
```
[project-name] › relative/file/path.spec.ts:42:42 › suite subsuite test title
```
- `Location` with `file`, `line` and `column`.
- `fullTitle` does not include project name.
- `titlePath` method.
- All methods of `Reporter` are optional.
- Removed `Test.skipped` property that is superseeded by `Test.status()`.
- Replaced `Suite.findTest()` with `Suite.allTests()`.
- Removed `Test.suite` property.
We now have Suites and Tests. When running multiple projects the whole
suite is cloned for each project. Same happens for repeatEach.
This simplifies the reporters API, but there is still room for improvement.
JSON reporter continues to produce old json output.
This avoids problems with `toMatchSnapshot('../../dir/file.png')`
where we append this path to `snapshotDir` and end up in some random
place.
Also added a note to documentation.
This fixes two issues:
- Sudden worker process exit is properly accounted for.
- We can stop() workers willy-nilly, e.g. after reaching maxFailures.
Details:
- DonePayload does not send `reamining` anymore, and worker does not track it.
- Instead, `Dispatcher._runJob` track remaining tests and acts accordingly.
- Upon worker exit, we emulate a fatal error for all remaining tests.
Drive-by:
- Do not report onTestBegin after reaching maxFailures to avoid confusion.
Before, we did report onTestBegin, but not onTestEnd.
- List reporter aligned between "running" and "finished" state - it was
one character misplaced.
- Added a SIGINT test.
