由于’android.content.res.Resources $ NotFoundException’导致检测运行失败

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:当LoginActivity调用MyService.java并且MyService需要整数资源(即R.integer.number_of_days)时,会导致“android.content.res.Resources $ NotFoundException”。 此资源在gradle(版本1.5.0)模块中的R.integer.xml文件中定义。

我的考试class:

 @RunWith(AndroidJUnit4.class) @LargeTest public class LoginActivityTest extends ActivityInstrumentationTestCase2{ @Rule public ActivityTestRule 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?

如果在测试和ActivityTestRule使用JUnit4,则不需要扩展ActivityInstrumentationTestCase2 ,也不需要构造函数。 修复你的代码,使它看起来像这样,然后再试一次:

 @RunWith(AndroidJUnit4.class) @LargeTest public class LoginActivityTest { @Rule public ActivityTestRule 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:请参阅代码中的注释

我遇到了同样的问题,问题出在build.gradle中

我降低了浓缩咖啡的速度
