Functions

func RunGpuCUJ

func RunGpuCUJ(ctx context.Context, cr *chrome.Chrome, params TestParams, serverURL, traceDir string) (
	retPV *perf.Values, retCleanup lacrosperf.CleanupCallback, retErr error)

RunGpuCUJ runs a GpuCUJ test according to the given parameters.

Types

type TestParams

type TestParams struct {
	TestType TestType
	Rot90    bool // Whether to rotate the screen 90 or not.
}

TestParams holds parameters describing how to run a GpuCUJ test.

type TestType

type TestType string

TestType describes the type of GpuCUJ test to run.

	// TestTypeMaximized is a simple test of performance with a maximized window opening various web content.
