android-espresso - 在 Android 北极狐上运行测试类时未检测到 Espresso 测试

Question

我刚刚开始为现有的 android 应用程序进行 UI 测试，我确实按照文档设置了 espresso，我也在测试设备上禁用了动画。

然后我在里面创建了一个新的测试类src/androidTest，内容如下：

package com.myApp.customer.ui;

import androidx.test.espresso.Espresso;
import androidx.test.espresso.ViewInteraction;
import androidx.test.ext.junit.rules.ActivityScenarioRule;
import androidx.test.ext.junit.runners.AndroidJUnit4;

import android.view.View;
import android.view.ViewGroup;
import android.view.ViewParent;

import static androidx.test.espresso.action.ViewActions.*;
import static androidx.test.espresso.assertion.ViewAssertions.*;
import static androidx.test.espresso.matcher.ViewMatchers.*;

import com.shahry.customer.R;

import org.hamcrest.Description;
import org.hamcrest.Matcher;
import org.hamcrest.TypeSafeMatcher;
import org.hamcrest.core.IsInstanceOf;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

import static org.hamcrest.Matchers.allOf;
import static org.hamcrest.Matchers.anything;
import static org.hamcrest.Matchers.is;

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {

    @Rule
    public ActivityScenarioRule<MainActivity> activityRule
            = new ActivityScenarioRule<>(MainActivity.class);

    @Test
    public void checkBrowseButton_IsDisplayed(){
        ViewInteraction materialButton = Espresso.onView(
                allOf(withId(R.id.bBrowse), withText("Browse products"),
                        isDisplayed()));
        materialButton.check(matches(withText("Shop Online")));

    }
    @Test
    public void mainActivityTest() {
        ViewInteraction materialButton = Espresso.onView(
                allOf(withId(R.id.bBrowse), withText("Browse products"),
                        isDisplayed()));
        materialButton.perform(click());

        ViewInteraction linearLayout = Espresso.onView(
                allOf(withId(R.id.wPayOffline),
                        withParent(allOf(withId(R.id.llAppBar),
                                withParent(IsInstanceOf.<View>instanceOf(android.view.ViewGroup.class)))),
                        isDisplayed()));
        linearLayout.check(matches(isDisplayed()));

        ViewInteraction textView = Espresso.onView(
                allOf(withId(R.id.tvShopOnline), withText("Shop Online"),
                        withParent(allOf(withId(R.id.llAppBar),
                                withParent(IsInstanceOf.<View>instanceOf(android.view.ViewGroup.class)))),
                        isDisplayed()));
        textView.check(matches(withText("Shop Online")));
    }
}

当我尝试运行这个内部包含 2 个测试的测试类时，测试没有运行，如下面的屏幕截图所示，表明里面有 n 个测试。
