Functions ¶

func CheckFeatureMatrix ¶

func CheckFeatureMatrix[K comparable](t *testing.T, fm internal.FeatureMatrix[K])

func CheckFeatureTest ¶

func CheckFeatureTest(t *testing.T, fn func() error)

func ClangBin ¶

func ClangBin(tb testing.TB) string

func Contains ¶

func Contains[T, I any](i I) bool

Contains checks if interface value I is of type T. Use with qt.Satisfies:

qt.Assert(t, qt.Satisfies(p, testutils.Contains[*ebpf.Program]))

func CreateCgroup ¶

func CreateCgroup(tb testing.TB) *os.File

func DupFD ¶

func DupFD(tb testing.TB, fd int) int

func Files ¶

func Files(t *testing.T, files []string, fn func(*testing.T, string))

Files calls fn for each given file.

The function errors out if the pattern matches no files.

func GetCgroupIno ¶

func GetCgroupIno(t *testing.T, cgroup *os.File) uint64

func Glob ¶

func Glob(tb testing.TB, pattern string, excludes ...string) []string

Glob finds files matching a pattern.

The pattern should may include full path. Excludes use the same syntax as pattern, but are only applied to the basename instead of the full path.

func IsDeepCopy ¶

func IsDeepCopy[T any](got, want T) qt.Checker

IsDeepCopy checks that got is a deep copy of want.

All primitive values must be equal, but pointers must be distinct. This is different from reflect.DeepEqual which will accept equal pointer values. That is, reflect.DeepEqual(a, a) is true, while IsDeepCopy(a, a) is false.

func IsVersionLessThan ¶

func IsVersionLessThan(tb testing.TB, minVersions ...string) bool

Check whether the current runtime version is less than some minimum.

func LockOSThreadToSingleCPU ¶

func LockOSThreadToSingleCPU(tb testing.TB)

LockOSThreadToSingleCPU force the current goroutine to run on a single CPU.

func NativeFile ¶

func NativeFile(tb testing.TB, path string) string

NativeFile substitutes %s with an abbreviation of the host endianness.

func Rand ¶

func Rand(tb testing.TB) *rand.Rand

func SkipIfNotSupported ¶

func SkipIfNotSupported(tb testing.TB, err error)

func SkipIfNotSupportedOnOS ¶

func SkipIfNotSupportedOnOS(tb testing.TB, err error)

func SkipOnOldKernel ¶

func SkipOnOldKernel(tb testing.TB, minVersion, feature string)

Skip a test based on the Linux version we are running on.

Warning: this function does not have an effect on platforms other than Linux.

func TempBPFFS ¶

func TempBPFFS(tb testing.TB) string

TempBPFFS creates a temporary directory on a BPF FS.

The directory is automatically cleaned up at the end of the test run.
