Android Espresso：如何测试按钮点击是否会迁移到新屏幕？

Question

onView(withId(R.id.BUTTON))
    .perform(click())
    .check(matches(withContentDescription(R.id.my_layout)));
onView(withId(R.id.tp_layout))
    .check(matches(isDisplayed()));

I am trying to test whether button click migrates to next screen or not.. how can I match, with this only first test is running and it displays tests failed.

You can use Espresso extension - Espresso-Intents.

Here is the official tutorial .

Short quote:

Espresso-Intents records all intents that attempt to launch activities from the application under test. Using the intended API (cousin of Mockito.verify), you can assert that a given intent has been seen.
