Either running these once total or running them once per process
would be the wrong choice for a significant chunk of users, so do
neither. Later we'll add a new API for exactly-once setup and teardown
in parallel mode.
Each spec file is only loaded in a single worker, so top level
before/afterEach can't behave consistently.
beforeEach/afterEach are still supported in:
* Helper files
* describe() blocks
* At the top level of spec files in non-parallel mode
* Generally simplifies error handling in browsers
* Makes Jasmine's own integration tests easier to debug
* Stack traces will be provided for more global errors
* ... but less error information will be provided in some browsers if the
error comes from a file:// URL (use `npx serve` or similar instead)
* Jasmine will no longer override existing onerror handlers in browsers
* Setting window.onerror will no longer override Jasmine's global error
handling (use jasmine.spyOnGlobalErrors instead)
* Avoid setTimeout in Node, because we don't need the overhead there.
* Still call setTimeout in browsers to prevent the tab from being killed.
* Use queueMicrotask in Safari, because it's dramatically faster than
MessageChannel there.
* Continue to use MessageChannel in other supported browsers becuase it's
somewhat faster than queueMicrotask there.
* Don't use setImmediate any more because there's a faster alternative in
all supported envs.
In jasmine-core's own test suite, this yields a roughly 50-70% speedup
in Node, ~20% in Edge, and 75-90%(!) in Safari.
* The `boot` function exported by the core module returns the same object
every time it's called.
* Removed node_boot.js. Use the exported `boot` function instead
* JasmineStartedInfo does not have totalSpecsDefined or order in parallel mode
* JasmineDoneInfo does not have order in parallel mode
* Added incompleteCode and numWorkers to JasmineDoneInfo
Previously, an error that occurred after Jasmine started to report the
suiteDone or specDone event for the current runable would not be reliably
reported. Now such an error is reported on the nearest ancestor suite whose
suiteDone event has not yet been reported.
