我正在使用AndroidJUnitRunner和Espresso。
我写了一个简单的测试,但始终收到此异常。根据Stackoverflow的回答,问题是弄乱JUnit3和JUnit4,但我从未在我的项目中使用过JUnit3。
junit.framework.AssertionFailedError:在com.walletsaver.app.test.espresso.SignUpPopupTest中找不到测试
package com.walletsaver.app.test.espresso;
import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;
import android.test.suitebuilder.annotation.SmallTest;
import com.walletsaver.app.activity.LoginActivity;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import static android.support.test.espresso.Espresso.onView;
import static android.support.test.espresso.action.ViewActions.click;
import static android.support.test.espresso.matcher.ViewMatchers.withText;
@RunWith(AndroidJUnit4.class)
@SmallTest
public class SignUpPopupTest {
@Rule
public ActivityTestRule<LoginActivity> mActivityRule =
new ActivityTestRule<>(LoginActivity.class);
@Test
public void checkSignUpPopup() throws Exception {
onView(withText("Sign Up")).perform(click());
}
}

我发现了问题。
它在主模块的build.gradle
中丢失了代码。
如果你有这个问题,我建议先添加这一行:
android {
...
defaultConfig {
...
testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
}
...
}
