我想知道如何在JUnit中将我的测试标记为@Test，因为到目前为止我必须使用＆＃39;测试...＆＃39;名称。这意味着：
@Test
private void creatingAcc(){
而不是
private void testCreatingAcc(){

是的，你可以做到。请按照以下步骤实现：
转到您的应用build.gradle文件并添加如下所示的测试依赖关系：
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support:support-annotations:24.1.1'
compile 'com.jayway.android.robotium:robotium-solo:5.6.1'
现在你的build.gradle应该是这样的：
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.1"
defaultConfig {
applicationId "com.example.piotr.myapplication"
minSdkVersion 15
targetSdkVersion 21
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.android.support:design:24.1.1'
androidTestCompile 'com.android.support.test:runner:0.4.1'
androidTestCompile 'com.android.support.test:rules:0.4.1'
androidTestCompile 'com.android.support:support-annotations:24.1.1'
compile 'com.jayway.android.robotium:robotium-solo:5.6.1'
}
然后你需要转到你的androidTest目录并创建Java类并命名为例如MyActivityTestRule
在此文件中输入以下代码：
@Beta
public class MyActivityTestRule<T extends Activity> extends UiThreadTestRule {
private static final String TAG = "ActivityInstrumentationRule";
private final Class<T> mActivityClass;
public Instrumentation getInstrumentation() {
return mInstrumentation;
}
private Instrumentation mInstrumentation;
private boolean mInitialTouchMode = false;
private boolean mLaunchActivity = false;
private T mActivity;
/**
* Similar to {@link #MyActivityTestRule(Class, boolean, boolean)} but with "touch mode" disabled.
*
* @param activityClass The activity under test. This must be a class in the instrumentation
* targetPackage specified in the AndroidManifest.xml
* @see MyActivityTestRule#MyActivityTestRule(Class, boolean, boolean)
*/
public MyActivityTestRule(Class<T> activityClass) {
this(activityClass, false);
}
/**

* activity under test once per

}

嗯，说实话，这是标准ActivityTestRule带有额外的getter getInstrumentation()，我将在我的测试类中使用。
创建一个新的Java类 - 它将是您的测试类并将代码放在下面：
@RunWith(AndroidJUnit4.class)
public class MainActivityTest {
private Solo solo;
private static final String MAIN_ACTIVITY = MainActivity.class.getSimpleName();
@Rule
public MyActivityTestRule<MainActivity> mActivityRule = new MyActivityTestRule<>(MainActivity.class);
@Before
public void setUp() throws Exception {
solo = new Solo(mActivityRule.getInstrumentation(), mActivityRule.getActivity());
}
@Test
public void checkIfMainActivityIsProperlyDisplayed() throws InterruptedException {
solo.waitForActivity("MainActivity", 2000);
solo.assertCurrentActivity(mActivityRule.getActivity().getString(
R.string.error_no_class_def_found, MAIN_ACTIVITY), MAIN_ACTIVITY);
solo.getText("Hello World").isShown();
}
}
正如你所看到的那样并不困难。
希望它会有所帮助
