我是JBehave的新手,並試圖使用JBehave-JUnit-Runner在Eclipse Luna(在Ubuntu 12.04上)的JUnit中很好地顯示測試結果。我正在使用JBehave-JUnit-Runner 1.1.2,JUnit 4.12-beta-1和JBehave-core 4.0-beta-9。當我右鍵單擊我的故事文件並選擇「以JUnit測試運行」時,一切都很順利。然而,當我把@RunWith(JUnitReportingRunner.class)在我的故事類的頂部,需要JBehave-的JUnit亞軍,我得到以下錯誤:JBehave-Junit-Runner投擲NullPointerException

這裏是我的測試工具類。一個方法,非常簡單:
package org.felimar;
public abstract class StringManipulation
{
public static boolean stringBlank(final String src)
{
return src.matches("^\\s*$"); //$NON-NLS-1$
}
}
爲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|
步驟類:
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);
}
}
最後,故事類:
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中是否有任何明顯的錯誤他編碼,還是應該退出使用beta庫?
乍一看,代碼看起來很好。 我還沒有嘗試過4.0版本。同一個例子是否與穩定版本的JBehave一起工作?如果是的話,我想問你,在github上跟蹤器中爲此創建一個問題:https://github.com/codecentric/jbehave-junit-runner/issues – AndreasEK 2014-09-01 05:04:57
你可以嘗試的一件事是使用 JUnitReportingRunner.recommandedControls(configuredEmbedder()); 在你的構造函數中作爲最後一行,如下所示: https://github.com/codecentric/jbehave-junit-runner#enabling – AndreasEK 2014-09-01 05:15:11
謝謝你的建議Andreas。我已經回答了我的問題,以解釋您的哪些建議對我有用,並根據您的要求在GitHub(#70)提出了一個問題。 – Flic 2014-09-03 14:37:54
