robolectric을 실행할 때 알 수없는 오류가 발생했습니다.

Question

robolectric을 처음 사용하기 때문에 간단한 테스트 만 실행하면됩니다.

내가 사용하는 안드로이드 스튜디오 => Gradle을

내 샘플 테스트를 실행하여

@RunWith(RobolectricTestRunner.class) 
public class ExampleTest extends InstrumentationTestCase { 

@Test 
public void test() throws Exception { 
    final int expected = 5; 
    final int reality = 5; 
    assertEquals(expected, reality); 
} 
} 

Gradle을

./gradlew clean test --stacktrace 

나는 예외 가지고

 

    test.ExampleTest > test FAILED 
     java.lang.RuntimeException 
      Caused by: java.lang.NullPointerException 

    1 test completed, 1 failed 
    :app:testDebug FAILED 

    FAILURE: Build failed with an exception. 

    * What went wrong: 
    Execution failed for task ':app:testDebug'. 
    > There were failing tests. See the report at: file:///Users/gburanov/code/mobile/Medoo.Android/app/build/test-report/debug/index.html 

    * Try: 
    Run with --info or --debug option to get more log output. 

    * Exception is: 

    org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:testDebug'.

어떻게 찾을 수 정말 그렇게 오류의 요지? 널 포인트 예외 어디?

Answer 1

Robolectric의 경우 InstrumentationTestCase를 확장하면 안됩니다.

Answer 2

더 실패 세부 사항에 당신의 경로 여야합니다
