我成功地让Robolectric在一个gradle项目中工作。现在我在使用Android Annotations时遇到问题。因此,我已经加入了测试包和主程序包(Android Annotations的Generated类只有包可见性)。我在https://github.com/excilys/androidannotations/wiki/Unit-test-your-application阅读了有关单元测试的部分。
任何与活动无关的测试都有效,例如:
@Test
public void testTrueIsTrue() throws Exception {
Assertions.assertThat(true);
}
现在的问题是,当尝试执行有关活动及其生命周期的测试时,测试会因NoClassDefFoundError而失败。您是否知道如何测试活动?关于此的测试是例如:
@Test
public void testActivity() {
MainActivity_ mainActivity = new MainActivity_();
mainActivity.onCreate(null);
Assert.assertNotNull(mainActivity);
}
或
@Test
public void testRobolectricActivity() {
ActionBarActivity activity = Robolectric.buildActivity(MainActivity_.class).create().get();
Assert.assertNotNull(activity);
}
最后一次测试的结果错误及其堆栈跟踪是:

我很感激一些帮助。提前谢谢。

我还没有使用过roboelectric,但听起来AA要么没有产生类别。
在apt_generated文件夹中查找MainAcitvity_,检查文件是否存在,并且它具有hasviews方法。
其次,这会对非生成类
产生影响@Test
public void testActivity() {
MainActivity mainActivity = new MainActivity_();
mainActivity.onCreate(null);
Assert.assertNotNull(mainActivity);
}

我有类似的问题。问题是由于错误仍然找不到生成的类。 而且我看到你也在使用SNAPSHOT版本,我也有。
我不确定,但在我的情况下,Android Annotations没有告诉我在我的带注释的代码中有错误,但我检查了最近编码的方法,并意识到我用@Background注释的一个方法具有私有访问权限。这是问题所在。在制作包装之后,一切都恢复了。
另一个问题可能是您没有在tests vm选项中正确指定构建目录。因此,您必须执行以下操作:
将编辑配置下的vm选项重置为-ea(默认值)。 之后你会得到一个STUB!执行测试时出现异常,它抱怨junit版本。将异常控制台顶部的所有内容(它稍微灰色,你必须打开它)复制到编辑器中,删除-classpath之前的所有内容以及不属于类路径的所有内容(意味着不用以下分隔:和追加构建目录的最后一个路径:
在我的案例中看起来像这样:
-classpath /home/user/.gradle/caches/modules-2/files-2.1/junit/junit/4.12-SNAPSHOT/d0f5ec9e335da2ea2827c781a46a02d8b6bbd556/junit-4.12-SNAPSHOT.jar:/home/user/android-studio/lib/idea_rt.jar:/home/user/android-studio/plugins/junit/lib/junit-rt.jar:/home/user/android-sdk/platforms/android-19/android.jar:/home/user/android-sdk/platforms/android-19/data/res:/home/user/android-sdk/tools/support/annotations.jar: [... deleted some dependencies here ...] /home/user/.gradle/caches/modules-2/files-2.1/org.robolectric/robolectric/2.4-SNAPSHOT/78161192eaadd6c7c56f6cf48040fa46897163d0/robolectric-2.4-SNAPSHOT.jar:/home/user/.gradle/caches/modules-2/files-2.1/org.ow2.asm/asm-util/5.0.1/7c8caddfbd0b2d7b844f8fcc75175b9cb9cf4724/asm-util-5.0.1.jar:/home/user/.gradle/caches/modules-2/files-2.1/com.google.code.gson/gson/2.3-SNAPSHOT/90850100a41d5695e2780773e2fc33198dea70d/gson-2.3-SNAPSHOT.jar:/home/user/development/App/app/build/generated
之后应找到课程。
我希望这会有所帮助......

如果没有看到您的项目设置,我不明白您的问题。我能告诉你robolectric和android注释一起工作。这是我的示例应用模板,其中包含活动测试https://github.com/nenick/android-gradle-template
