test: move shared module to test/common

Trott · targos · commit b2a465e616a0 · 2024-07-28T09:51:47.000+02:00
`test/fixtures/process-exit-code-cases.js` is a shared module and should be in `test/common` (so it gets linted, etc.) and documented in `test/common/README.md`.

+The `process-exit-code-test-cases` module provides a set of shared test cases

+* `isWorker` [\<boolean>][<boolean>]

+Returns an array of test cases for testing the exit codes of the `process`. Each
+test case is an object with a `func` property that is a function that runs the
+test case, a `result` property that is the expected exit code, and sometimes an
+`error` property that is a regular expression that the error message should
+match when the test case is run in a worker thread.
+
+The `isWorker` parameter is used to adjust the test cases for worker threads.
+The default value is `false`.
