Similar to UiController but with one additional method that enables interrupting Espresso
tasks.
Provides base-level UI operations (such as injection of MotionEvents) that can be used to
build user actions such as clicks, scrolls, swipes, etc. This replaces parts of the android
Instrumentation class that provides similar functionality. However, it provides a more advanced
synchronization mechanism for test actions. The key differentiators are:
test actions are assumed to be called on the main thread
after a test action is initiated, execution blocks until all messages in the main message
queue have been cleared.
if the event couldn't be injected because it would
interact with another application. @Deprecated Please use injectMotionEventSequence this
method will be removed in future.
Types a string into the application using series of KeyEvents. It is up to the
implementor to decide how to map the string to KeyEvent objects. If you need specific
control over the key events generated use injectKeyEvent(KeyEvent).
if the events couldn't be injected because it would
interact with another application.
loopMainThreadForAtLeast
public abstract void loopMainThreadForAtLeast (long millisDelay)
Loops the main thread for a specified period of time.
Control may not return immediately, instead it'll return after the provided delay has passed
and the queue is in an idle state again.
Parameters
millisDelay
long: time to spend in looping the main thread
loopMainThreadUntilIdle
public abstract void loopMainThreadUntilIdle ()
Loops the main thread until the application goes idle.
An empty task is immediately inserted into the task queue to ensure that if we're idle at
this moment we'll return instantly.
