如何从espresso中推出另一个活动测试案例

我对Espresso非常陌生。我正在编写android应用程序的测试用例。我的问题是如何从第一个活动启动第二个活动的测试用例。如何从espresso中推出另一个活动测试案例

首先activty的测试用例是如下次活动（的Test2）的

你为什么要考同样的事情两次？

即使你想，我认为它不是一个很好的方法来从另一个测试方法中手动调用（相同或其他活动的）测试方法。这就是为什么这些是首先进行单独测试的原因。

但是，可以包括的Test2的测试代码到下面的ZTEST方法：

@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 
}
