android - 使用 Espresso 测试启动 Activity Intent

Question

我想做一个简单的 UI 测试，按下一个按钮并启动一个 Activity 。

我试过基于this documentation. (安卓开发者)

SplashActivity 代码:

public class SplashActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);

    findViewById(R.id.launch_register_activity_btn).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent intent = new Intent(SplashActivity.this, RegisterActivity.class);
            startActivity(intent);
        }
    });
}
}

测试代码:

@RunWith(AndroidJUnit4.class)
public class SimpleIntentTest {

@Rule
public IntentsTestRule<SplashActivity> intentsRule = new IntentsTestRule<>(SplashActivity.class);

@Test
public void newActivityLaunchingTest() {


    onView(withId(R.id.launch_register_activity_btn)).perform(click());

    Log.i("register-package_name", RegisterActivity.class.getPackage().toString());
    Log.i("register-class_name", RegisterActivity.class.getName());
    Log.i("register-short_name", RegisterActivity.class.getSimpleName());


    intended(allOf(
            hasComponent(hasShortClassName(".RegisterActivity")),
            toPackage("re.example.common")
    ));


}
}

日志:

01-22 13:37:51.615: I/register-package_name(25292): package re.example.common, Unknown, version 0.0
01-22 13:37:51.615: I/register-class_name(25292): re.example.common.RegisterActivity
01-22 13:37:51.615: I/register-short_name(25292): RegisterActivity

包结构:

测试输出:

android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: Wanted to match 1 intents. Actually matched 0 intents.

IntentMatcher: (has component: has component with: class name: an instance of java.lang.String package name: an instance of java.lang.String short class name: is ".RegisterActivity" and resolvesTo: re.example.common)

Matched intents:[]

无论我如何尝试，测试都无法验证我是否启动了 RegisterActivity。测试失败。

据我所知，我所做的与上面链接中的 Espresso 测试示例完全一样。

我做错了什么？

我也试过:

<强>1。删除 . (点)来自“.RegisterActivity”

intended(allOf(
            hasComponent(hasShortClassName("RegisterActivity")),
            toPackage("re.example.common")
    ));

<强>2。删除 . (点)来自 ".RegisterActivity" 和 toPackage("re.example.common")

intended(allOf(
            hasComponent(hasShortClassName("RegisterActivity"))
    ));

我的 RegisterActivity 的包名称是 "re.example.common.RegisterActivity"。简称 名称是“RegisterActivity”。不是吗？

为什么测试失败？

这是怎么回事，我有什么误解或误解？

提前致谢。

Answer 1

Application id (app package name is) is: re.example (source gradle)

Activity 的全名是:re.example.common.RegisterActivity

这样，hasShortClassName 意味着 .common.RegisterActivity 作为 shortName 而不是 .RegisterActivity 也不是 注册 Activity

嗯。
