ViewAction
java.lang.Object | |
↳ | android.support.test.espresso.action.RepeatActionUntilViewState |
Enables performing a given action on a view until it reaches desired state matched by given View
matcher. This action is useful in the scenarios where performing the action repeatedly on a view
changes its state at runtime. For example, if there is a ViewFlipper
on which user can
swipe through the views and it automatically flips between each child at a regular interval, it
is not always certain which of the child is displayed at a given point of time. In this case, in
order to perform click on child no. 4 (assuming child no. 4 contains a text "Child 4"), repeat
action can be used as follows:
int maxAttempts=10; onView(withId(R.id.my_pager)) .perform(repeatedlyUntil(swipeUp(), hasDescendant(withText("Child 4")), maxAttempts), click());
