type DetectedLanguage ¶ added in v1.6.0

type DetectedLanguage struct {
	Language string   // detected language ("java", "python", etc.)
	RunCmd   string   // run command ("java", "python3", etc.)
	RunArgs  []string // run arguments (e.g. ["-cp", ".", "TestE01"])
}

DetectedLanguage holds the runtime info for a language detected by CompileStep Language="auto". Populated by the framework in Phase 2; consumed by TestFunc via harness.DetectedLang.

type TestCaseHarness ¶

type TestCaseHarness struct {
	// Logger is to be used for all logs generated from the test function.
	Logger *logger.Logger

	// SubmissionDir is the directory containing the student's submission.
	// Use this for direct file access without needing your_program.sh.
	SubmissionDir string

	// Executable is the program to be tested (may point to SubmissionDir if no ExecutableFileName).
	Executable *executable.Executable

	// DetectedLang is the auto-detected language info from CompileStep Language="auto".
	// nil when Language is not "auto". TestFunc reads RunCmd/RunArgs to run the test driver.
	DetectedLang *DetectedLanguage
	// contains filtered or unexported fields
}

TestCaseHarness is passed to your TestCase's TestFunc.

For TensorHero courses that don't use your_program.sh, use SubmissionDir directly:

if !harness.FileExists("hello.c") {
    return fmt.Errorf("hello.c does not exist")
}

For long-lived programs (like a Redis server), use Executable:

if err := harness.Executable.Start(); err != nil {
   return err
}
harness.RegisterTeardownFunc(func() { harness.Executable.Kill() })

For scripts that run and exit (like a Git command):

result, err := harness.Executable.Run("cat-file", "-p", "sha")
if err != nil {
    return err
}
