我是JBehave的新手,并试图使用JBehave-JUnit-Runner在Eclipse Luna(在Ubuntu 12.04上)的JUnit中很好地显示测试结果。我正在使用JBehave-JUnit-Runner 1.1.2,JUnit 4.12-beta-1和JBehave-core 4.0-beta-9。当我右键单击我的故事文件并选择“以JUnit测试运行”时,一切都很顺利。然而,当我把@RunWith(JUnitReportingRunner.class)在我的故事类的顶部,需要JBehave-的JUnit亚军,我得到以下错误:JBehave-Junit-Runner投掷NullPointerException

这里是我的测试工具类。一个方法,非常简单:
package org.felimar;
public abstract class StringManipulation
{
public static boolean stringBlank(final String src)
{
return src.matches("^\\s*$"); //$NON-NLS-1$
}
}
为JBehave的故事文件:
Utilities for managing character strings
Narrative:
In order to easily manipulate and investigate character strings
As a development team
I want to use a group of string-related utilities
Scenario: A string contains zero or more characters
Given a source string with value <value>
Then the method should return <return>
Examples:
|value|return|
|""|true|
|" "|true|
|"Normal Non-Blank"|false|
步骤类:
package org.felimar.steps;
import static org.felimar.StringManipulation.stringBlank;
import org.felimar.StringManipulation;
import org.jbehave.core.annotations.Given;
import org.jbehave.core.annotations.Named;
import org.jbehave.core.annotations.Then;
public class StringManipulationSteps
{
private String m_srcString;
public String getSrcString()
{
return m_srcString;
}
@Given("a source string with value $value")
public void givenValue(@Named("value") final String srcString)
{
setSrcString(srcString);
}
public void setSrcString(final String srcString)
{
m_srcString = srcString;
}
@Then("the method should return $value")
public void stringBlankRtrns(@Named("value") final boolean isBlank)
{
if (stringBlank(getSrcString()) != isBlank)
throw new RuntimeException("stringBlank did not determine *" +
getSrcString() + "* was " + isBlank);
}
}
最后,故事类:
package org.felimar.stories;
import static java.util.Arrays.asList;
import static org.jbehave.core.reporters.Format.CONSOLE;
import static org.jbehave.core.reporters.Format.TXT;
import java.util.List;
import org.felimar.StringManipulation;
import org.felimar.steps.StringManipulationSteps;
import org.jbehave.core.configuration.MostUsefulConfiguration;
import org.jbehave.core.junit.JUnitStories;
import org.jbehave.core.reporters.StoryReporterBuilder;
import org.jbehave.core.steps.InjectableStepsFactory;
import org.jbehave.core.steps.InstanceStepsFactory;
import org.junit.runner.RunWith;
import de.codecentric.jbehave.junit.monitoring.JUnitReportingRunner;
@RunWith(JUnitReportingRunner.class)
public class StringManipulationStories extends JUnitStories
{
public StringManipulationStories()
{
super();
super.useConfiguration(
new MostUsefulConfiguration().useStoryReporterBuilder(
new StoryReporterBuilder().withDefaultFormats().withFormats(
CONSOLE, TXT)));
}
@Override
public InjectableStepsFactory stepsFactory()
{
return new InstanceStepsFactory(configuration(),
new StringManipulationSteps());
}
@Override
protected List<String> storyPaths()
{
return asList("org/felimar/stories/StringManipulationStories.story");
}
}
t中是否有任何明显的错误他编码,还是应该退出使用beta库?
乍一看,代码看起来很好。 我还没有尝试过4.0版本。同一个例子是否与稳定版本的JBehave一起工作?如果是的话,我想问你,在github上跟踪器中为此创建一个问题:https://github.com/codecentric/jbehave-junit-runner/issues – AndreasEK 2014-09-01 05:04:57
你可以尝试的一件事是使用 JUnitReportingRunner.recommandedControls(configuredEmbedder()); 在你的构造函数中作为最后一行,如下所示: https://github.com/codecentric/jbehave-junit-runner#enabling – AndreasEK 2014-09-01 05:15:11
谢谢你的建议Andreas。我已经回答了我的问题,以解释您的哪些建议对我有用,并根据您的要求在GitHub(#70)提出了一个问题。 – Flic 2014-09-03 14:37:54
