【问题描述】：
我正在尝试在我的 Android 应用程序中添加一个基本的浓缩咖啡测试。我的测试文件（位于 androidTest/java 文件夹中）由“记录浓缩咖啡测试”功能生成，如下所示：
package info.my_xxxx.activities;
import android.support.test.espresso.ViewInteraction;
import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;
import android.test.suitebuilder.annotation.LargeTest;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewParent;
import org.hamcrest.Description;
import org.hamcrest.Matcher;
import org.hamcrest.TypeSafeMatcher;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;
import info.my_xxxx.R;
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.allOf;
@LargeTest
@RunWith(AndroidJUnit4.class)
public class AdviceDisplay2 {
@Rule
public IntentsTestRule<SplashActivity> mActivityTestRule = new IntentsTestRule<>(SplashActivity.class);
@Test
public void adviceDisplay2() {
// Added a sleep statement to match the app's execution delay.
// The recommended way to handle such scenarios is to use Espresso idling resources:
// https://google.github.io/android-testing-support-library/docs/espresso/idling-resource/index.html
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
ViewInteraction appCompatImageView = onView(
allOf(withId(R.id.third_button),
childAtPosition(
allOf(withId(R.id.linear_layout),
childAtPosition(
withId(R.id.bottom_button),
0)),
2),
isDisplayed()));
appCompatImageView.perform(click());
ViewInteraction textView = onView(
allOf(withId(R.id.advice),
childAtPosition(
allOf(withId(R.id.RelativeLayout01),
childAtPosition(
withId(android.R.id.content),
0)),
1),
isDisplayed()));
textView.check(matches(isDisplayed()));
}
private static Matcher<View> childAtPosition(
final Matcher<View> parentMatcher, final int position) {
return new TypeSafeMatcher<View>() {
@Override
public void describeTo(Description description) {
description.appendText("Child at position " + position + " in parent ");
parentMatcher.describeTo(description);
}
@Override
public boolean matchesSafely(View view) {
ViewParent parent = view.getParent();
return parent instanceof ViewGroup && parentMatcher.matches(parent)
&& view.equals(((ViewGroup) parent).getChildAt(position));
}
};
}
}
如您所见，它只是单击视图并检查视图是否存在...我的 gradle 文件（模块级别）是：
buildscript {

maven { url 'https://maven.fabric.io/public' }

classpath 'io.fabric.tools:gradle:1.+'

}
}
所有依赖项似乎都可以，但是从 android studio 运行测试时，几分钟后我收到了这条消息：
android.support.test.espresso.AppNotIdleException：循环 2969 迭代超过 60 秒。以下空闲条件失败。在 dalvik.system.VMStack.getThreadStackTrace（本机方法）在 java.lang.Thread.getStackTrace(Thread.java:1536) 在 android.support.test.espresso.base.DefaultFailureHandler.getUserFriendlyError(DefaultFailureHandler.java:90) 在 android.support.test.espresso.base.DefaultFailureHandler.handle(DefaultFailureHandler.java:52) 在 android.support.test.espresso.ViewInteraction.waitForAndHandleInteractionResults(ViewInteraction.java:312) 在 android.support.test.espresso.ViewInteraction.desugaredPerform(ViewInteraction.java:167) 在 android.support.test.espresso.ViewInteraction.perform(ViewInteraction.java:110) 在 info.xxx.activities.AdviceDisplay2.adviceDisplay2(AdviceDisplay2.java:56) 在 java.lang.reflect.Method.invoke(Native Method) 在 org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) 在 org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) 在 org.junit.runners.model.FrameworkMethod.invokeExplosively（FrameworkMethod.java:47） 在 org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) 在 android.support.test.rule.ActivityTestRule$ActivityStatement.evaluate(ActivityTestRule.java:433) 在 org.junit.rules.RunRules.evaluate(RunRules.java:20) 在 org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) 在 org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) 在 org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) 在 org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) 在 org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) 在 org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) 在 org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) 在 org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) 在 org.junit.runners.ParentRunner.run(ParentRunner.java:363) 在 org.junit.runners.Suite.runChild(Suite.java:128) 在 org.junit.runners.Suite.runChild(Suite.java:27) 在 org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) 在 org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) 在 org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) 在 org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) 在 org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) 在 org.junit.runners.ParentRunner.run(ParentRunner.java:363) 在 org.junit.runner.JUnitCore.run(JUnitCore.java:137) 在 org.junit.runner.JUnitCore.run(JUnitCore.java:115) 在 android.support.test.internal.runner.TestExecutor.execute(TestExecutor.java:58) 在 android.support.test.runner.AndroidJUnitRunner.onStart(AndroidJUnitRunner.java:375) 在 android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:2074)
测试运行完成。
第 56 行是：
appCompatImageView.perform(click());

如何将 Espresso 集成到您的项目中。我像你一样使用它的依赖，但它没有定义。
