我是Espresso的新手。我正在为Android应用程序编写测试用例。 我的问题是如何从First活动中启动第二个活动的测试用例。
第一次激活的测试用例如下

答案 0 :(得分：0)
为什么你会两次测试同样的东西？
即使您愿意，我认为从另一个测试方法中手动调用测试方法（相同或其他活动）也不是一个好方法。这就是为什么这些首先是单独的测试。
但是，您可以将Test2的测试代码包含在ztest方法中，如下所示：
@Test
public void zlaunch(){
onView(withId(R.id.next)).perform(click());
// here instead of launching test cases of Second Activity
// you can copy/paste the same code from Test2 again as below
// Spoon.screenshot(mActivity, "initial_state");
onView(withId(R.id.user_name)).perform(typeText("invalid"),closeSoftKeyboard());
onView(withId(R.id.submit)).perform(click());
//and so on
}
