junit.framework.AssertionFailedError：TextViewに正しいテキストが含まれています

Question

私は単純なrobolectricクラスを持っています。私はtextViewのString値をチェックします。テストでは、TextViewが存在し、テキストが "Hello World！"であるかどうかを単純にチェックします。

@Config(constants = BuildConfig.class, sdk = Build.VERSION_CODES.LOLLIPOP) 
@RunWith(RobolectricGradleTestRunner.class) 
public class MainActivityTest { 
private MainActivity activity; 


@Test 
public void validateTextViewContent() { 
    activity = Robolectric.setupActivity(MainActivity.class); 
    TextView tvHelloWorld = (TextView) activity.findViewById(R.id.tvHelloWorld); 

    assertNotNull("TextView could not be found", tvHelloWorld); 
    assertTrue("TextView contains correct text", 
      "Hello world!".equals(tvHelloWorld.getText().toString())); 
    } 
} 

私はそれを実行すると、次のエラーが発生します。

junit.framework.AssertionFailedError: TextView contains correct text

Answer 1

問題が修正さ

おかげで!!!私がいるassertTrueを取り除き、

assertEquals(tvHelloWorld.getText().toString(), "Hello World!");
