我只是想用Robolectric测试一个fragment中是否有特定的视图。 我的单元测试如下:
ActivityController controller = Robolectric.buildActivity(FragmentActivity.class);
FragmentActivity activity = (FragmentActivity) controller.create().start().resume().visible().get();
F fragment = new MyFragment();
activity.getSupportFragmentManager().beginTransaction()
.add(fragment, FRAGMENT_TAG).commit();
View view = fragment.getView().findViewById(R.id.my_view);
assertEquals(view.getVisibility(), View.VISIBLE);
我正在使用最新的android gradle插件1.1.3,robolectirc 2.4和robolectric gradle插件1.0.1,并且我的单元测试位于test
文件夹中(而非androidTest
)。但是我无法编译该代码,因为编译器无法解析R.java
。
我的build.gradle
文件:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.1.3'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
classpath 'org.robolectric:robolectric-gradle-plugin:1.0.1'
}
}
apply plugin: 'com.android.library'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'org.robolectric'
android { ... }
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
// Testing
testCompile 'org.robolectric:robolectric:2.4'
testCompile 'junit:junit:4.12'
// Other dependencies
...
}
我该如何使用Robolectric编写单元测试?
更新: 以下是完整代码:
public class TestFragment extends Fragment {
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_listview_ptr, container, false);
}
}
public class MyFragmentTest {
private static final String FRAGMENT_TAG = "fragment";
private ActivityController controller;
private FragmentActivity activity;
@Test
protected void displaysContentView(boolean pullToRefreshSupported) {
controller = Robolectric.buildActivity(FragmentActivity.class);
activity = (FragmentActivity) controller.create().start().resume().visible().get();
Fragment fragment = new TestFragment();
FragmentManager manager = activity.getSupportFragmentManager();
manager.beginTransaction()
.add(fragment, FRAGMENT_TAG).commit();
// Compile errors here
View loadingView = fragment.getView().findViewById(R.id.loadingView);
View contentView = fragment.getView().findViewById(R.id.contentView);
View errorView = fragment.getView().findViewById(R.id.loadingView);
Assert.assertNotSame(loadingView.getVisibility(), View.VISIBLE);
Assert.assertNotSame(errorView.getVisibility(), View.VISIBLE);
Assert.assertEquals(contentView.getVisibility(), View.VISIBLE);
}
}

build.gradle
文件吗?前4行可以替换成下一行代码F fragment = new MyFragment(); FragmentTestUtil.startVisibleFragment( fragment );
。 - Eugen Martynovbuild.gradle
文件。我知道可以使用FragmentTestUtils
替代它。但我没有使用FragmentTestUtils
的原因是我没有使用FragmentActivity
,而是另一个使用特殊 dagger 模块和测试 mocks 的 Activity。出于简单起见,我将其省略了。 - sockeqwe
