我是 android 测试的新手。如果用户单击按钮并且 TextView 为空,我试图让测试失败。有没有办法在 Espresso 中执行此操作,因此如果 TextView 为空,它将失败。我不想检查 TextView 是否包含特定文本,我想检查它是否不为空。
最佳答案
试试这个:
import static android.support.test.espresso.Espresso.onView;
import static android.support.test.espresso.action.ViewActions.click;
import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.isDisplayed;
import static android.support.test.espresso.matcher.ViewMatchers.withId;
import static android.support.test.espresso.matcher.ViewMatchers.withText;
import static org.hamcrest.Matchers.not;
@RunWith(AndroidJUnit4.class)
public class MainActivityInstrumentedTest {
@Rule
public ActivityTestRule<MainActivity> mActivityTestRule =
new ActivityTestRule<>(MainActivity.class);
@Test
public void checkTextView_isDisplayed_and_notEmpty() throws Exception {
// perform a click on the button
onView(withId(R.id.button)).perform(click());
// passes if the textView does not match the empty string
onView(withId(R.id.textView)).check(matches(not(withText(""))));
}
}
只有当 textView 包含任何文本时,测试才会通过。
关于android - 使用 Espresso 测试 TextView 值不为空,如果 TextView 值为空则失败,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/46598149/
