Functions ¶
func ConfirmPixelCountInActivitySurface ¶
func ConfirmPixelCountInActivitySurface(ctx context.Context, cr *chrome.Chrome, a *arc.ARC, clr color.Color, nonScaledPixelCount int, act *arc.Activity) error
ConfirmPixelCountInActivitySurface confirms that 1.25 scaling has been correctly applied by checking the number of clr pixels drawn.
func MeasureDisplayDensity ¶
MeasureDisplayDensity initializes the display and returns its physical density.
func RunTest ¶
func RunTest(ctx context.Context, cr *chrome.Chrome, a *arc.ARC, packageName string, testSteps []Change, activity string, expectedInitialPixelCount float64) error
RunTest takes a slice of activity names and a slice of density changes and executes them.
func SetUpApk ¶
SetUpApk enables developer option for density changes, and installs the specified apk.
func StartActivityWithWindowState ¶
func StartActivityWithWindowState(ctx context.Context, tconn *chrome.TestConn, a *arc.ARC, windowState arc.WindowState, activity string) (*arc.Activity, error)
StartActivityWithWindowState starts the view activity with the specified window state. It is the responsibility of the caller to close the activity.
Types ¶
type Change ¶
type Change struct {
// The action that should be performed to the current density.
Name string
// The corresponding key sequence to perform the action.
KeySequence string
// The expected pixel count after performing the current action.
BlackPixelCount float64
}
Change is a struct containing information to perform density changes.
