Android的ES preSSO错误没有发现测试 [英] Android espresso error no tests found

问题描述

我尝试使用长者preSSO测试框架来测试我的应用程序。

I try to use Espresso test framework for testing my app.

ENV：

Android的工作室RC1（从金丝雀）
最新的Andr​​oid摇篮插件，0.14 +

Android Studio RC1 (from canary) Latest Android Gradle plugin, 0.14+

我说这里所描述（的 HTTPS：//$c$c.google.com/p/android-test-kit/wiki/Es$p$psso#Getting_Started ）

dependencies {
    //espresso - test framework

    androidTestCompile files('libs/espresso-1.1.jar',
            'libs/testrunner-1.1.jar',
            'libs/testrunner-runtime-1.1.jar')

    androidTestCompile 'com.google.guava:guava:14.0.1',
            'com.squareup.dagger:dagger:1.1.0',
            'org.hamcrest:hamcrest-core:1.1',
            'org.hamcrest:hamcrest-integration:1.1',
            'org.hamcrest:hamcrest-library:1.1'
}

 packagingOptions {
        exclude 'LICENSE.txt'
    }

defaultConfig {
        //espresso - test framework
        testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"
    }

此外，我创建了简单的测试：

Also I created simple test:

public class StartActivityTest extends ActivityInstrumentationTestCase2<StartActivity> {
    public StartActivityTest(Class<StartActivity> activityClass) {
        super(activityClass);
    }

    @Override
    public void setUp() throws Exception {
        super.setUp();
        // Espresso will not launch our activity for us, we must launch it via getActivity().
        getActivity();
    }

    public void testStartVisibility() {
        onView(withId(R.id.app_title))
                .check(matches(isDisplayed()));

        onView(withId(R.id.app_thumb))
                .check(matches(isDisplayed()));

        onView(withId(R.id.label))
                .check(matches(isDisplayed())
                );

        onView(withId(R.id.label)).check(matches(withText("Hello Espresso!")));
    }

}

但我得到一个错误：

But i get an error:

com.android.builder.testing.ConnectedDevice > hasTests[Nexus 5 - 5.0] FAILED 
No tests found.                           
:app:connectedAndroidTest FAILED          

FAILURE: Build failed with an exception.

推荐答案

好吧，我知道了。

我有如下使用默认的构造函数：

I have to use default constructor as below:

public StartActivityTest() {
    super(StartActivity.class);
}

这是固定的问题。
