func RepoRoot ¶

func RepoRoot() string

RepoRoot returns the project root by walking up from the caller's source file to the nearest directory containing go.mod.

func RunTimestamp ¶

func RunTimestamp() string

RunTimestamp returns a stable timestamp for the current test binary run. All tests in the same `go test` invocation share the same value.

func ShortSHA ¶

func ShortSHA() string

ShortSHA returns the abbreviated commit hash of HEAD.

func TestResultsDir ¶

func TestResultsDir(t *testing.T, baseDirFn func() string) string

TestResultsDir returns a persistent results directory for a test:

test/results/<timestamp>-<RootTestName>/<subtest/path>/

All subtests of the same root test share one timestamped parent directory. The directory is created automatically.

baseDirFn optionally overrides the base directory (the directory containing test/results/). When nil, RepoRoot() is used. Pass a custom function when the results path must be remapped (e.g. Docker host path translation).
