问题描述



我必须确保robolectric-xxjar出现在android.jar之前,否则我会得到可怕的RuntimeException(Stub!)。

我该怎么做? 解决方案

这是我完整的 build.gradle ,用于针对使用RoboGuice的Android应用程序运行Robolectric测试:

  apply plugin:'java'

androidJar = new File(System.getenv('ANDROID_HOME'),'/ platforms / android-7 / android.jar')

配置{robo}

依赖关系{
robo('com.pivotallabs:robolectric:1.0-RC1')
testCompile ('org.roboguice:roboguice:1.1.2')
testCompile('junit:junit:4.8.2')
testCompile项目(':app')
testCompile文件(androidJar)
}

sourceSets.test.compileClasspath =配置。 robo + sourceSets.test.compileClasspath
sourceSets.test.runtimeClasspath = configurations.robo + sourceSets.test.runtimeClasspath

test {
excludes = ['** / MyRobolectricTestRunner.class ']
}

我必须为测试运行器添加一个排除项,否则Gradle将会抛出一个异常。


$ b MyRobolectricTestRunner.java 看起来像这样:

  package com.acme.myapp; 

import java.io.File;
import org.junit.runners.model.InitializationError;
导入roboguice.application.RoboApplication;
导入roboguice.inject.ContextScope;
import com.google.inject.Injector;
import com.xtremelabs.robolectric.Robolectric;
import com.xtremelabs.robolectric.RobolectricTestRunner;

public class MyRobolectricTestRunner扩展了RobolectricTestRunner {
public MyRobolectricTestRunner(Class<> testClass)throws InitializationError {
//告诉Robolectric在哪里可以找到AndroidManifest.xml和res /
super(testClass,new File(../ app));
}

/ **
*启用注入测试以及...
* /
@Override
public void prepareTest对象测试){
RoboApplication myApplication =(RoboApplication)Robolectric.application;
注射器注射器= myApplication.getInjector();
ContextScope contextScope = injector.getInstance(ContextScope.class);
contextScope.enter(myApplication);
injector.injectMembers(test);
}

}

下面是一个示例测试,注入:

  package com.acme.myapp; 

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.RunWith;
导入roboguice.inject.InjectResource;

@RunWith(MyRobolectricTestRunner.class)
public class StringFormattingTest {

@InjectResource(R.string.info_pending_amount)
private String pendingAmountPattern;

@Test
public void testFormatInfoPendingAmount(){
String s = String.format(pendingAmountPattern,20.0d,EUR);
assertEquals(只有部分股份(20,00 EUR)被接受,s);
}

}


I need to control the ordering of jars in the testRuntime configuration.

I must make sure that robolectric-x.x.jar comes before android.jar, or else I get the dreaded RuntimeException("Stub!").

How do I do that?

解决方案

Here is my complete build.gradle for running Robolectric tests against my Android app, which uses RoboGuice:

apply plugin: 'java'

androidJar = new File(System.getenv('ANDROID_HOME'), '/platforms/android-7/android.jar')

configurations { robo }

dependencies {
    robo('com.pivotallabs:robolectric:1.0-RC1')
    testCompile('org.roboguice:roboguice:1.1.2')
    testCompile('junit:junit:4.8.2')
    testCompile project (':app')
    testCompile files(androidJar)
}

sourceSets.test.compileClasspath = configurations.robo + sourceSets.test.compileClasspath
sourceSets.test.runtimeClasspath = configurations.robo + sourceSets.test.runtimeClasspath

test {
    excludes = ['**/MyRobolectricTestRunner.class']
}

I had to add an exclusion for the test runner, or else Gradle will throw an exception.

MyRobolectricTestRunner.java looks like this:

package com.acme.myapp;

import java.io.File;
import org.junit.runners.model.InitializationError;
import roboguice.application.RoboApplication;
import roboguice.inject.ContextScope;
import com.google.inject.Injector;
import com.xtremelabs.robolectric.Robolectric;
import com.xtremelabs.robolectric.RobolectricTestRunner;

public class MyRobolectricTestRunner extends RobolectricTestRunner {
    public MyRobolectricTestRunner(Class<?> testClass) throws InitializationError {
        // Tell Robolectric where to find AndroidManifest.xml and res/
        super(testClass, new File("../app"));
    }

    /**
     * Enable injection into tests as well...
     */
    @Override
    public void prepareTest(Object test) {
        RoboApplication myApplication = (RoboApplication) Robolectric.application;
        Injector injector = myApplication.getInjector();
        ContextScope contextScope = injector.getInstance(ContextScope.class);
        contextScope.enter(myApplication);
        injector.injectMembers(test);
    }

}

And here's a sample test that illustrates injection:

package com.acme.myapp;

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.RunWith;
import roboguice.inject.InjectResource;

@RunWith(MyRobolectricTestRunner.class)
public class StringFormattingTest {

    @InjectResource(R.string.info_pending_amount)
    private String pendingAmountPattern;

    @Test
    public void testFormatInfoPendingAmount() {
        String s = String.format(pendingAmountPattern, 20.0d, "EUR");
        assertEquals("Only a part of your stake (20,00 EUR) was accepted", s);
    }

}
