我想在我的 Android 应用程序中测试我的 MainActivity。因此,我创建了第一个测试按钮功能的测试用例。如果用户单击此特定按钮,则应打开一个新 Activity 。

这是我的代码:

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {

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

@Test
public void startNewActivityTest() {
Intents.init();
onView(withId(R.id.main_new)).perform(click());
intended(hasComponent(NewActivity.class.getName()));
Intents.release();
}

@Before
public void setup() {
closeSoftKeyboard();
}

}

不幸的是,我得到以下异常:

junit.framework.AssertionFailedError: No tests found in package.MainActivityTest
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:191)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:176)
at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:554)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1701)

这是我的 Gradle 文件:

apply plugin: 'com.android.application'

android {
compileSdkVersion 19
buildToolsVersion "23.0.1"

lintOptions {
abortOnError false
}

defaultConfig {
applicationId "package"
minSdkVersion 14
targetSdkVersion 19
}

signingConfigs {
debug {
storeFile file(RELEASE_STORE_FILE)
storePassword RELEASE_STORE_PASSWORD
keyAlias RELEASE_KEY_ALIAS
keyPassword RELEASE_KEY_PASSWORD
}
release {
storeFile file(RELEASE_STORE_FILE)
storePassword RELEASE_STORE_PASSWORD
keyAlias RELEASE_KEY_ALIAS
keyPassword RELEASE_KEY_PASSWORD
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}

dependencies {
compile 'com.android.support:support-v4:19.1.0'
compile 'com.google.android.gms:play-services:4.2.+'
androidTestCompile 'com.android.support:support-annotations:19.0.1'
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'
// Set this dependency if you want to use Hamcrest matching
androidTestCompile 'org.hamcrest:hamcrest-library:1.3'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
}

最佳答案

Set the instrumentation runner

Add to the same build.gradle file the following line in android.defaultConfig: testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

apply plugin: 'com.android.application'

android {
...

defaultConfig {
...

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
}

dependencies {
// App's dependencies, including test
compile 'com.android.support:support-annotations:23.0.1'

...
}

我从未使用过 Espresso Intents,但也许您需要 this喜欢here :

Use IntentsTestRule instead of ActivityTestRule when using Espresso-Intents. IntentsTestRule makes it easy to use Espresso-Intents APIs in functional UI tests. This class is an extension of ActivityTestRule, which initializes Espresso-Intents before each test annotated with @Test and releases Espresso-Intents after each test run. The activity will be terminated after each test and this rule can be used in the same way as ActivityTestRule.
