* use subclass of unittest.TestCase for all test cases
* allow to run single test file (eg. python tools/integration_tests.py)
* test filtering (via --pattern/-p CLI flag)
* use common CLI parser for all tests:
usage: test.py [-h] [--failfast] [--verbose] [--executable EXECUTABLE]
[--release] [--pattern PATTERN] [--build-dir BUILD_DIR]
optional arguments:
-h, --help show this help message and exit
--failfast, -f Stop on first failure
--verbose, -v Verbose output
--executable EXECUTABLE
Use external executable of Deno
--release Test against release executable
--pattern PATTERN, -p PATTERN
Run tests that match provided pattern
--build-dir BUILD_DIR
Deno build directory
* respect NO_COLOR variable
