不能使我的Espresso UI測試工作。問題在哪裏？
我應該爲這個簡單的應用程序考慮它的工作結果？Android Espresso：測試運行失敗。沒有測試結果空的測試套件。爲什麼？
我有「android.support.test.runner.AndroidJUnitRunner」用於儀表亞軍Edit Confirurations。
從AndroidManifest.xml中：
<instrumentation
android:name="android.support.test.runner.AndroidJUnitRunner"
android:targetPackage="my.package"/>
從的build.gradle：
defaultConfig {
applicationId "my.package"
minSdkVersion 18
targetSdkVersion 22
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
packagingOptions {
exclude 'LICENSE.txt'}
repositories { jcenter()}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:support-annotations:22.2.0'
androidTestCompile 'com.android.support.test:runner:0.3'
androidTestCompile 'com.android.support.test:rules:0.3'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'
testCompile 'junit:junit:4.12'}
MainActivity.java
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText editText = (EditText)findViewById(R.id.edit_text);
Button button = (Button) findViewById(R.id.confirm);
final TextView textView = (TextView)findViewById(R.id.you_entered);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
textView.setText("You entered: " + editText.getText());
}
});
}
}
ApplicationTest.java
public class ApplicationTest extends ApplicationTestCase<Application> {
public ApplicationTest() {
super(Application.class);
}
}
MainActivityTest
public class MainActivityTest extends ActivityInstrumentationTestCase2 <MainActivity> {
Activity activity;
public MainActivityTest() {
super(MainActivity.class);
}
@Override
public void setUp() throws Exception {
super.setUp();
activity = getActivity();
}
@SmallTest
public void testInputOutput() {
Espresso.onView(ViewMatchers.withId(R.id.edit_text)).perform(ViewActions.click())
.perform(ViewActions.typeText("Espresso"));
Espresso.onView(ViewMatchers.withId(R.id.confirm)).perform(ViewActions.click());
Espresso.onView(ViewMatchers.withId(R.id.you_entered)).check(ViewAssertions.matches
(ViewMatchers.withText("Espresso")));
assertEquals(((TextView)ViewMatchers.withId(R.id.you_entered)).getText(), "Espresso");
}
}
