我尝试在 Android Studio 1.5.1 中使用 espresso 2.2.1 运行测试。当我运行 LoginActivityTest 时，我收到此错误：“android.content.res.Resources$NotFoundException”在 LoginActivity 调用 MyService.java 并且 MyService 需要整数资源（即 R.integer.number_of_days）时引起。此资源在 gradle（版本 1.5.0）模块的 R.integer.xml 文件中定义。

项目结构：

RootFolder/ ├----projectA/ │ ├----build.gradle │ ├----settings.gradle │ └----src/androidTest/java/.../LoginActivityTest │ └----src/main/java/.../LoginActivity │ └----Module/ ├----krill/ │ └----build.gradle │ ├----settings.gradle │ └----src/main/ | └----java/service/MyService.java | └----res/value/integers.xml │ └----otherModule/ └----build.gradle

我的测试课：

@RunWith(AndroidJUnit4.class)
@LargeTest
public class LoginActivityTest extends ActivityInstrumentationTestCase2<LoginActivity >{

@Rule
public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule(LoginActivity.class);

public LoginActivityTest() {
    super(LoginActivity.class);
}

@Test
public void testConfigDialog() {
    onView(withId(R.layout.login_custom_view));

    onView(withId(R.id.id_username)).perform(clearText());
    onView(withId(R.id.id_password)).perform(clearText());
}
}

我该如何解决这个问题？

如果您在测试中使用 JUnit4，ActivityTestRule那么您不需要扩展ActivityInstrumentationTestCase2<LoginActivity>也不需要构造函数。修复您的代码，使其看起来像这样，然后重试：

@RunWith(AndroidJUnit4.class)
@LargeTest
public class LoginActivityTest {

    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule(LoginActivity.class);

    @Test
    public void testConfigDialog() {
        onView(withId(R.layout.login_custom_view)); //you can't use layout id here there must be a view id

        onView(withId(R.id.id_username)).perform(clearText());
        onView(withId(R.id.id_password)).perform(clearText());
    }
}

更新：查看代码中的注释

我有同样的问题，问题出在 build.gradle

我降级浓缩咖啡

androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
