Functions ¶

func ExitIfSmallMachine ¶

func ExitIfSmallMachine()

ExitIfSmallMachine emits a helpful diagnostic and calls os.Exit(0) if the current machine is a builder known to have scarce resources.

It should be called from within a TestMain function.

func Go1Point ¶

func Go1Point() int

Go1Point returns the x in Go 1.x.

func NeedsGo1Point ¶

func NeedsGo1Point(t Testing, x int)

NeedsGo1Point skips t if the Go version used to run the test is older than 1.x.

func NeedsGoBuild ¶

func NeedsGoBuild(t Testing)

NeedsGoBuild skips t if the current system can't build programs with “go build” and then run them with os.StartProcess or exec.Command. android, and darwin/arm systems don't have the userspace go build needs to run, and js/wasm doesn't support running subprocesses.

func NeedsGoPackages ¶

func NeedsGoPackages(t Testing)

NeedsGoPackages skips t if the go/packages driver (or 'go' tool) implied by the current process environment is not present in the path.

func NeedsGoPackagesEnv ¶

func NeedsGoPackagesEnv(t Testing, env []string)

NeedsGoPackagesEnv skips t if the go/packages driver (or 'go' tool) implied by env is not present in the path.

func NeedsTool ¶

func NeedsTool(t Testing, tool string)

NeedsTool skips t if the named tool is not present in the path. As a special case, "cgo" means "go" is present and can compile cgo programs.

func SkipAfterGo1Point ¶

func SkipAfterGo1Point(t Testing, x int)

SkipAfterGo1Point skips t if the Go version used to run the test is newer than 1.x.

Types ¶

type Testing ¶

type Testing interface {
	Skipf(format string, args ...interface{})
	Fatalf(format string, args ...interface{})
}

Testing is an abstraction of a *testing.T.
