How to make UI Automator wait until TextView's text value changes

I am currently doing some cross-app functional UI testing.

There is a TextView that exists and that I must test for its text value. I must thus find a way to wait for the TextView's text value to change.

Here is my usecase : 

final UiSelector contextualInformation = new UiSelector().resourceId(resourceId);
final UiObject contextualInformationUiObject = mDevice.findObject(contextualInformation);

// I would like to find something to fulfill this statement
Boolean conditionWasMet = contextualInformationUiObject.wait(Until./*a search condition for text to contain given substring*/, timeout);

assertThat(conditionWasMet, is(notNullValue()));
assertThat(conditionWasMet, is(true));
assertThat(contextualInformationUiObject.exists(), is(true));
assertThat(contextualInformationUiObject.getText(), containsString(/*given substring*/));

I am well aware of the existence of Until.textContains(/*substring*/) but I do not know how to apply it to/with contextualInformation or contextualInformationUiObject here.

Solution

  • As far as I know, if your process doesn't possess any onFinished callback, there is no way but to use Thread.sleep(). This is what I did on my latest project:

    final long waitingTime = 5000L;
Thread.sleep(averageWaitingTime);

    You can just adjust the waitingTime. The idea is to buy enough time for your process to finish.
