Function TestRunnerOptionsFromFlags

tools/celtest/test_runner.go:184–211

TestRunnerOptionsFromFlags returns a TestRunnerOption which configures the following attributes of the test runner using the parsed flags and the optionally provided test runner and test compiler options: - Test compiler - The `file_descriptor_set`, `base_config_path` and `config_path` flags are use

(testResourcesDir string, testRunnerOpts []TestRunnerOption, testCompilerOpts ...any)

//     evaluated by the test runner.
//   - Enable coverage - The `enable_coverage` flag is used to enable coverage calculation and reporting.
