This adds an exit sanitizer to ensure that code being tested or
dependencies of that code can't accidentally call "Deno.exit"
leading to partial test runs and false results.
This commit renames two assertion functions to better align with JS API:
- assertStringContains -> assertStringIncludes
- assertArrayContains -> assertArrayIncludes
Currently, the documentation makes it sound like the test subcommand's filter
flag could accept some kind of pattern matching value like a glob or a regex,
although the function "createFilterFn" accepts a regex as an argument, there's
no way to pass an actual regex value from the CLI.
This commit makes it possible to pass a string that could be cast as regex
when string matches "^/.*/$".
With this change, a user can use the filter flag as follow:
deno test --filter "/test-.+/"
Also tested that `\` get escaped properly, on MacOS at least, and this is
also a valid flag:
deno test --filter "/test-\d+/"
