junit.framework.AssertionFailedError：TextView包含正確的文本

我有簡單的robolectric類，我檢查了我的textView的字符串值。測試只是檢查我們的TextView是否存在並且具有文本「Hello World！」junit.framework.AssertionFailedError：TextView包含正確的文本

@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())); 
    } 
}

當我運行它雖然，我得到以下錯誤。

的第一件事是，你可以代替assertTrue的使用的assertEquals。但我認爲這可能無法幫助你。 – toshkinl

不，它不能與assertEquals一起工作:( – Theo

嘗試在聲明前添加一些文本到該TextView中） tvHelloWorld.setText（「」）; – toshkinl

問題固定!!!我刪除了assertTrue，並將此行

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