我正在尝试运行安卓仪器测试，似乎在模拟器上运行给出了测试结果，但在真实设备上它不起作用，输出为"测试运行失败：没有测试结果">
下面是我的build.gradle文件
apply plugin: 'com.android.application'

下面是我的简单测试用例，我从活动中找到一个按钮并将按钮文本与静态字符串进行比较
import android.widget.Button;
import androidx.test.ext.junit.runners.AndroidJUnit4;
import androidx.test.rule.ActivityTestRule;
import org.junit.After;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import salesken.app.R;
import static com.google.common.truth.Truth.assertThat;
@RunWith(AndroidJUnit4.class)
public class LoginActivityTest {
@Rule
public ActivityTestRule<LoginActivity> loginActivityTestRule = new ActivityTestRule<LoginActivity>(LoginActivity.class);
private LoginActivity loginActivity= null;
@Before
public void setUp() throws Exception {
loginActivity =loginActivityTestRule.getActivity();
}
@After
public void tearDown() throws Exception {
loginActivity = null;
}
@Test
public void testLaunch(){
Button view = loginActivity.findViewById(R.id.login);
assertThat(view.getText().toString()).isEqualTo("LOG IN");
}
}
我不明白为什么它不能在真实设备上工作。 以下是我在真实设备上运行测试时生成的日志

在OnePlus上运行测试之前，您应该去
设置 ->电池 ->电池优化 -> 您的应用程序(不是 package.test but application( -> 不要优化 -> 完成
这将禁用后台限制，测试将正常工作。
