android - 具有Android注释的Robolectric

Question

我在项目中使用android-annotations，然后开始学习单元测试。我正在尝试使用robolectric执行测试，但没有成功(Android Studio 8.6和Gradle)。
通过一些教程，我可以配置build.gradle，如果执行简单的测试而不访问任何 Activity ，则测试会生成OK结果。但是，当我尝试执行访问 Activity 的测试时，会发生错误。

错误

LoginActivityTest > testActivityAA2 FAILED
java.lang.RuntimeException at LoginActivityTest.java:33
Caused by: java.lang.reflect.InvocationTargetException at LoginActivityTest.java:33
Caused by: java.lang.IllegalStateException at LoginActivityTest.java:33

我的测试

@Config(manifest = "./src/main/AndroidManifest.xml", emulateSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class LoginActivityTest extends InstrumentationTestCase {

    //This is OK
    @Test
    public void testNumbers() throws Exception{
        final int expected = 5;
        final int reality = 5;
        assertEquals(expected, reality);
    }

    // this occurs error
    @Test
    public void testActivityAA2() throws Exception {
        LoginActivity_ loginnActivity = new LoginActivity_();
        loginnActivity.onCreate(null);
        assertNotNull(loginnActivity);
    }
}

你能帮我吗？

您不应该像Robolectric测试那样初始化Activity。
使用Robolectric.buildActivity()(文档:http://robolectric.org/activity-lifecycle/)

例如:
Robolectric.buildActivity(LoginActivity.class).create()。get()

根据您需要测试的内容，您可以链接其他方法，例如visible()，start()等。
