Example 62 with UiController

use of android.support.test.espresso.UiController in project iosched by google.

the class MatchersHelper method getText.

/**
 * This returns the text for the view that has been matched with {@code matcher}. The matched
 * view is expected to be a {@link TextView}. This is different from matching a view by text,
 * this is intended to be used when matching a view by another mean (for example, by id) but
 * when we need to know the text of that view, for use later in a test.
 * <p/>
 * In general, this isn't good practice as tests should be written using mock data (so we always
 * know what the data is) but this enables us to write tests that are written using real data
 * (so we don't always know what the data is but we want to verify something later in a test).
 * This is enables us to write UI tests before refactoring a feature to make it easier to mock
 * the data.
