earlgrey

Can I see the exact UI hierarchy that EarlGrey uses to locate elements?

I am writing a test that fails with following error:

Error Domain=com.google.earlgrey.ElementInteractionErrorDomain Code=0 "No element found." UserInfo={NSLocalizedDescription=No element found.}

I can see in the generated screenshot that the element I am trying to match exists. I stepped through the code and saw that earlgrey uses element providers. When my test failed, I saw a ui hierarchy dump. I want to print the exact same ui hierarchy at specific breakpoints instead. How can I do that?

Solution

  • You can use the GREYElementHierarchy class to print the element hierarchy at any point in your EarlGrey test.

    UIWindow *hierarchy = [[[UIApplication sharedApplication] delegate] window]);

    NSLog(@"Hierarchy: %@", hierarchy);
