如何在Eclipse和Ant中使用不同的Junit Testrunner



我有几个我想从蚀和蚂蚁进行的JBEHAVE测试。在Eclipse中,我想看到一棵在图形输出中执行的所有不同故事,场景和步骤的树,因此我在执行此操作的测试中添加了自定义跑步者:

@RunWith(de.codecentric.jbehave.junit.monitoring.JUnitReportingRunner.class)
public class MyStoryTest extends org.jbehave.core.junit.JUnitStories
{
    // ...
}

但是,相反,当使用ANT和连续的集成服务器运行测试时,我只想将每个故事都视为输出中的一个项目。这通常是没有任何注释而实现的:

public class MyStoryTest extends JUnitStories
{
    // ...
}

那么,我该如何告诉蚂蚁(Junit Ant Task)使用与Eclipse不同的跑步者?为了使事情变得更加复杂:目前,我使用Eclipse(不在ANT)中的测试套件进行测试:

@RunWith(org.junit.extensions.cpsuite.ClasspathSuite.class)
@org.junit.extensions.cpsuite.ClassnameFilters("foo.mypackage.tests.*")
public class MyStoriesTestSuite
{
    // Nothing more to say ;)
}

有什么想法?

我几周前做了一些黑客,这可以满足您的需求。我意识到,如果单位测试运行始终包含以其名称的软件包,则由Eclipse执行的Java命令。因此,如果这给出了True,则可能是您在Eclipse下进行测试:

System.getProperty( "sun.java.command" ).contains( "org.eclipse.jdt" )

我知道,它不是100%的解决方案,而是通常有效,而且它总比没有好

我为您创建并测试了一个跑步者 注释对:

注释

package org.junit.annotation;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import org.junit.runner.Runner;
import org.junit.runners.JUnit4;
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Target( ElementType.TYPE )
public @interface RunWithInEnvironment {
    Class<? extends Runner> eclipse();
    Class<? extends Runner> defaultRunner() default JUnit4.class;
}

默认情况下,它使用junit4作为defaultrunner,这实际上是junit4的默认值。

跑步者,使用注释的信息:

package org.junit.runners;
import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.fail;
import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;
import org.junit.annotation.RunWithInEnvironment;
import org.junit.runner.Description;
import org.junit.runner.Runner;
import org.junit.runner.notification.RunNotifier;
public class EnvironmentDependentRunner extends Runner {
    protected Class<?> testClass;
    protected Runner delegate;
    public EnvironmentDependentRunner(Class<?> testClass) {
        super();
        this.testClass = testClass;
        RunWithInEnvironment annotation = findAnnotationInClassHierarchy(testClass);
        assertNotNull( EnvironmentDependentRunner.class.getSimpleName() + " can be used only with test classes, that are annotated with " + RunWithInEnvironment.class.getSimpleName() + " annotation somewhere in their class hierarchy!", annotation );
        Class<? extends Runner> delegateClass = null;
        if ( System.getProperty( "sun.java.command" ).contains( "org.eclipse.jdt" ) && annotation.eclipse() != null ) {
            delegateClass = annotation.eclipse();
        }
        else {
            delegateClass = annotation.defaultRunner();
        }
        try {
            Constructor<? extends Runner> constructor = delegateClass.getConstructor( Class.class );
            delegate = constructor.newInstance(testClass);
        } catch (NoSuchMethodException e) {
            fail( delegateClass.getName() + " must contain a public constructor with a " + Class.class.getName() + " argument.");
        } catch (SecurityException e) {
            throw new RuntimeException("SecurityException during instantiation of " + delegateClass.getName() );
        } catch (InstantiationException e) {
            throw new RuntimeException("Error while creating " + delegateClass.getName() );
        } catch (IllegalAccessException e) {
            throw new RuntimeException("Error while creating " + delegateClass.getName() );
        } catch (IllegalArgumentException e) {
            throw new RuntimeException("Error while creating " + delegateClass.getName() );
        } catch (InvocationTargetException e) {
            throw new RuntimeException("Error while creating " + delegateClass.getName() );
        }
    }
    private RunWithInEnvironment findAnnotationInClassHierarchy(Class<?> testClass) {
        RunWithInEnvironment annotation = testClass.getAnnotation(RunWithInEnvironment.class);
        if (annotation != null) {
            return annotation;
        }
        Class<?> superClass = testClass.getSuperclass();
        if (superClass != null) {
            return findAnnotationInClassHierarchy(superClass);
        }
        return null;
    }
    @Override
    public Description getDescription() {
        return delegate.getDescription();
    }
    @Override
    public void run(RunNotifier arg0) {
        delegate.run(arg0);
    }
}

用法示例

@RunWithInEnvironment( eclipse=JUnit4.class, defaultRunner=Parameterized.class)
@RunWith( EnvironmentDependentRunner.class)
public class FooTest {
...
}

因此,此测试将与Eclipse中的Junit4 Runner一起进行,并带有参数性的Eclipse。
