我使用的是Android Studio 1.2,Robolectric 3.0-rc2。
我有两个测试类,一个名为MotdTest
,其中一个测试方法测试POJO json序列化&反序列化。另一个名为UserInfoTest
,其中包含4个测试方法,用于测试我设置为SharedPreferences
的用户信息。如果我单独运行UserInfoTest
,则所有4种测试方法都会通过。但是,如果我运行所有测试,MotdTest
中的测试会成功,但UserInfoTest
的两种方法总是失败。我现在通过调用./gradlew test
当我运行所有测试时,有谁知道为什么我的某些测试失败了?在我的UserInfoTest中,我正确地使用@After
带注释的方法,通过在SharedPreferences.Editor
上调用clear()。commit()进行清理。
UserInfoTest:
testOnSignIn()
在assertThat(6, equalTo(prefs.getAll().size()));
失败,因为prefs
的大小为0.
testIsSignedIn()
<{1}}失败,assertThat(UserInfo.isSignedIn(), is(false));
@RunWith(MyRoboRunner.class)
@Config(constants = BuildConfig.class)
public class UserInfoTest {
private String mExpectedId;
private String mExpectedName;
private String mExpectedEmail;
private String mExpectedToken;
private String mExpectedKey;
@Before
public void setUp() throws Exception {
ShadowLog.stream = System.out;
mExpectedId = "someiD";
mExpectedName = "johnny boy";
mExpectedEmail = "some@email.com";
mExpectedToken = "Session Token";
mExpectedKey = "Session Key";
}
@After
public void tearDown() {
SharedPreferences prefs = RuntimeEnvironment.application.getSharedPreferences(
UserInfo.PREFERENCES, Context.MODE_PRIVATE);
prefs.edit().clear().commit();
mExpectedId = null;
mExpectedName = null;
mExpectedEmail = null;
mExpectedToken = null;
mExpectedKey = null;
}
@Test
public void testOnSignIn() {
SharedPreferences prefs = RuntimeEnvironment.application.getSharedPreferences(
UserInfo.PREFERENCES, Context.MODE_PRIVATE);
UserInfo.onSignIn(mExpectedId, mExpectedName, mExpectedEmail, mExpectedKey, mExpectedToken);
assertThat(mExpectedKey, equalTo(UserInfo.getSessionKey()));
assertThat(mExpectedToken, equalTo(UserInfo.getSessionToken()));
assertThat(mExpectedId, equalTo(UserInfo.getUserId()));
assertThat(mExpectedEmail, equalTo(UserInfo.getUserEmail()));
assertThat(mExpectedName, equalTo(UserInfo.getUserName()));
assertThat(6, equalTo(prefs.getAll().size()));
}
@Test
public void testOnSignOut() {
UserInfo.onSignIn(mExpectedId, mExpectedName, mExpectedEmail, mExpectedKey, mExpectedToken);
// Set Over21 to make sure we unset this value on Signout
UserInfo.setIsOver21(true);
UserInfo.onSignOut();
SharedPreferences prefs = RuntimeEnvironment.application.getSharedPreferences(
UserInfo.PREFERENCES, Context.MODE_PRIVATE);
assertThat(UserInfo.getSessionKey(), nullValue());
assertThat(UserInfo.getSessionToken(), nullValue());
assertThat(UserInfo.isOver21Set(), is(false));
assertThat(prefs.getAll().size(), equalTo(0));
}
@Test
public void testIsSignedIn() {
assertThat(UserInfo.isSignedIn(), is(false));
UserInfo.onSignIn(mExpectedId, mExpectedName, mExpectedEmail, mExpectedKey, mExpectedToken);
assertThat(UserInfo.isSignedIn(), is(true));
UserInfo.onSignOut();
assertThat(UserInfo.isSignedIn(), is(false));
}
@Test
public void testIsOver21Set() {
assertThat(UserInfo.isOver21Set(), is(false));
UserInfo.setIsOver21(false);
assertThat(UserInfo.isOver21Set(), is(true));
}
}
的UserInfo:
App
是Application
子类,App.getInstance()
是单身。
private static final SharedPreferences PREFS = App.getInstance()
.getSharedPreferences(PREFERENCES, Context.MODE_PRIVATE);
public static void onSignIn(String userId, String fullName, String email, String sessionKey,
String sessionToken) {
SharedPreferences.Editor editor = PREFS.edit();
editor.putString(PROPERTY_USER_ID, userId);
editor.putString(PROPERTY_USER_NAME, fullName);
editor.putString(PROPERTY_USER_EMAIL, email);
editor.putString(PROPERTY_SESSION_KEY, sessionKey);
editor.putString(PROPERTY_SESSION_TOKEN, sessionToken);
editor.putStringSet(PROPERTY_PENDING_SCANS, new HashSet<String>());
editor.commit();
}
public static boolean isSignedIn() {
return getSessionToken() != null;
}
MyRoboRunner:this的修改版本,因为我在Mac上,也因为我在我的项目中瞄准API 22,但是robolectric还不支持,所以我运行我的测试反对API 21.
public class MyRoboRunner extends RobolectricGradleTestRunner {
public MyRoboRunner(Class<?> klass) throws InitializationError {
super(klass);
}
protected AndroidManifest getAppManifest(Config config) {
AndroidManifest appManifest = super.getAppManifest(config);
String moduleRoot = getModuleRootPath(config);
//can use this line instead dynamic path resolution when AS bug is fix, or use @Config
//FsFile androidManifestFile = appManifest.getAndroidManifestFile();
FsFile androidManifestFile = FileFsFile.from(moduleRoot,
appManifest.getAndroidManifestFile().getPath()
.replace("bundles", "manifests/full"));
FsFile resDirectory = FileFsFile.from(moduleRoot, appManifest.getResDirectory().getPath());
FsFile assetsDirectory = FileFsFile
.from(moduleRoot, appManifest.getAssetsDirectory().getPath());
return new AndroidManifest(androidManifestFile, resDirectory, assetsDirectory) {
@Override
public int getTargetSdkVersion() {
//lollipop bc it's highest that robolectric 3.0 supports
return Build.VERSION_CODES.LOLLIPOP;
}
@Override
public int getMinSdkVersion() {
return Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1;
}
};
}
private String getModuleRootPath(Config config) {
String moduleRoot = config.constants().getResource("").toString().replace("file:", "");
return moduleRoot.substring(0, moduleRoot.indexOf("/build"));
}
}
答案 0 :(得分:1)
您在SharedPreferences
中保留对PREFS
的静态引用。我认为只要您在tearDown
方法中重置测试或删除静态参考,您的测试就会得到修复。如果删除静态引用,则SharedPreferences
本身将清除Robolectric
文件 - 无需在tearDown
中再次清除它。
还有一点需要提及 - 我也在使用Mac
,我对RobolectricGradleTestRunnner
没有任何问题。有时我必须在运行测试之前运行clean
,但没有别的。
你提到的另一件事robobolectric-gradle-plugin
。 Android Studio v1.1 +和android gradle插件v1.1 +
答案 1 :(得分:0)
使用robolectric gradle plugin并设置此属性已通过我的所有测试:
robolectric {
// Specify max number of processes (default is 1)
maxParallelForks = 2
}
但是,我仍然不知道为什么这会影响我的测试时单独运行和一起运行。此外,似乎不再需要robolectric gradle插件,因为我在Android Studio 1.2上,但我无法弄清楚如何在没有它的情况下让它工作并手动设置maxParallelForks属性。
