如何在浓缩咖啡中从另一个启动一个活动测试用例

Question

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

    package venki.estest;

第二活动（Test2）的测试用例如下：

Answer 1

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
}
