java - 测试android应用报错

Question

现在有一天我正在完成教程，我在 testApplication 中发现了这种类型的错误。 我应该怎么办？ 这是一个简单的 HeloAndroidTest 应用程序。

错误是

来自 future 的你好!

super("com.example.helloandroid", HelloAndroid.class)

已弃用。你需要在你的测试中有一个无参数的构造函数，这样将 Activity 传递给 super :

 public MyTest() {
        super(MyActivity.class);
    }

这就是此错误的原因和解决方法。
