Not updating Prettier because newer versions impose significant formatting
changes. In particular, 2.0 changes every function definition from
`function() {` to `function () {` with no way to opt out. I'm not willing
to accept that kind of churn just becuse the Prettier devs changed their
mind about what color the bikeshed should be.
We'll most likely stay on Prettier 1.17 for as long as it remains viable,
then either switch to an autoformatter that offers stability or just
remove it.
Node 16 will reach EOL no later than a few months after Jasmine 5 is
released. Experience with Node 12 and Node 14 has shown that our
dependencies, especially dev dependencies, move on from past-EOL Node
versions fairly quickly. That can make it difficult to continue supporting
them. Since long term support for past EOL Node versions is a non-goal and
many users expect that Node versions will only be dropped in major
releases, it's better to drop it in 5.0.
This is intended to support parallel execution, which is planned for a
future release of Jasmine. Because the execution of unrelated suites will
interleave when run in parallel, reporters will not be able to assume
that the most recent `suiteStarted` event identifies the parent of the
current suite/spec. By adding this feature now, we allow reporters to
support both parallel execution and at least some 4.x versions without
having to implement two different ways of finding the parent suite.
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
