test: adding tests for initHooks API
Async wrap providers tested:
- crypto.randomBytes
- crypto.pbkdf2
- fs event wrap
- fsreqwrap access
- fsreqwrap readFile
- getaddrinforeq wrap
- getnameinforeq wrap
- pipe connect wrap
- query wrap
- pipewrap
- processwrap
- shutdown wrap
- tcpwrap
- udpwrap
- send wrap
- detailed signal wrap
- statwatcher
- timerwrap via setTimeout
- timerwrap via setInterval
- for Immediate
- http parser request
- http parser response
- connection via ssl server
- tls wrap
- write wrap
- ttywrap via readstream
- ttywrap via wriream
- zctx via zlib binding deflate
Embedder API:
- async-event tests
- one test looks at the happy paths
- another ensures that in cases of events emitted in an order that
doesn't make sense, the order is enforced by async hooks throwing a
meaningful error
- embedder enforcement tests are split up since async hook stack
corruption now the process
- therefore we launch a child and check for error output of the offending code
Additional tests:
- tests that show that we can enable/disable hooks inside their lifetime
events
- tests that verify the graph of resources triggering the creation of
other resources
Test Helpers:
- init-hooks:
- returns one collector instance
- when created an async hook is created and the lifetime events are
registered to call the appropriate collector functions
- the collector also exposes `enable` and `disable` functions which call
through to the async hook
- hook checks:
- checks invocations of life time hooks against the actual invocations
that were collected
- in some cases like `destroy` a min/max range of invocations can be
supplied since in these cases the exact number is non-deterministic
- verify graph:
- verifies the triggerIds of specific async resources are as expected,
i.e. the creation of resources was triggered by the resource we expect
- includes a printGraph function to generate easily readable test
input for verify graph
- both functions prune TickObjects to create less brittle and easier
to understand tests
