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.
Stop wrapping/prepending error messages so that we do not loose the stack trace. For this, update a few manually thrown errors with better messages (usually including a file path).
Speed up locations by doing manual `sourceMapSupport.wrapCallSite()` for a single call site. Performance gain in the runner process with 100 files x 100 tests each:
- 25% on the fresh run without babel cache;
- 80% on the cached run where babel is almost instant.
Also some obvious cleanups around stack traces (removing unused code).
This fixes an issue where we incorrectly labeled and assigned ids for tests
that declared tests in require'd files or used test wrappers.
See new tests for examples.
