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。

我的测试类:
@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());
}
}

如何解决此问题?

如果您在测试和ActivityTestRule
中使用JUnit4,那么您不需要扩展ActivityInstrumentationTestCase2<LoginActivity>
并且不需要构造函数。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<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());
}
}

我遇到了同样的问题,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'
