上篇我们说到如何从Github上clone出一个JBehave项目，既是为了学习JBehava，也是为了熟悉下Github。
从clone下来的项目看来，基本没什么问题，稍微捋一捋就可以运行，但是就clone下来的代码来看，自己还是遇到一个问题（不知道是代码问题，还是我自己的操作有问题），就是没有办法运行（后面会详说）。
正如上篇所说，构建一个JBehave的应用的5大步骤：
这里，我们结合clone下来的项目分别对应这五个步骤了解JBehave是如何运行的并完成测试的。
1.Write story，设定一个story，给出一个情景，使用通用语言进行表示，不管是开发或是非开发的都能看懂
本项目有两个测试案例，一个是模拟登录的story:
|
1

10
11
|
loginYahoo.story：Narrative:In order to show the yahoo functionAs a userI want to login yahooScenario: normal loginGiven yahoo login address by.bouncer.login.yahoo.comThen print successful |
另一个是模拟浏览的story:

TestStroies.story：Browse Etsy.comMeta:@category browsing@color redNarrative:In order to show the browsing cart functionalityAs a userI want to browse in a galleryScenario: Browsing around the site for itemsGiven I am on localhostThen print hello world!--Examples:!--|host|hello|!--|localhost|hello world|!--|www.baidu.com|hello baidu| |
2.Map steps to Java， 将上述的每个story细分成每一个step，给出Given条件，则会得到Then的结果，从而将通用语言转换成可以通过代码逻辑描述的问题
loginYahoo.story对应的steps类TestLogin.java:
|
1

|
public class TestLogin { @Given("yahoo login address $url") public void getHostPage(String url){ System.out.println("++++++++++++++++++++++++++++++"+url); } @Then("print $successful") public void hello(String successful){ System.out.println("++++++++++++++++++++++++++++++"+successful); }} |
TestStories.story对应的steps类TestStep.java:
|
1

3
4
5
6
7
8

11
|
public class TestStep { @Given("I am on $host") public void getHostPage(String host){ System.out.println("----------------------"+host); } @Then("print $hello") public void hello(String hello){ System.out.println("----------------------"+hello); }} |
3.Configure Stories 配置一些映射关系，比如如何找到并加载story文件等

public class EmbedderBase extends Embedder{ @Override public EmbedderControls embedderControls() { return new EmbedderControls().doIgnoreFailureInStories(true).doIgnoreFailureInView(true); } @Override public Configuration configuration() { Class<? extends EmbedderBase> embedderClass = this.getClass(); //MostUsefulConfiguration使用默认的配置 return new MostUsefulConfiguration() //设置story文件的加载路径 .useStoryLoader(new LoadFromClasspath(embedderClass.getClassLoader())) //设定生成报告的相关配置 .useStoryReporterBuilder(new StoryReporterBuilder() .withCodeLocation(CodeLocations.codeLocationFromClass(embedderClass)) .withFormats(Format.CONSOLE, Format.TXT) .withCrossReference(new CrossReference())) //设定相关参数的转换 .useParameterConverters(new ParameterConverters() .addConverters(new DateConverter(new SimpleDateFormat("yyyy-MM-dd")))) // use custom date pattern .useStepMonitor(new SilentStepMonitor()); }} |
4.Run Stories

public class TraderStoryRunner { @Test(groups={"test"}) public void runClasspathLoadedStoriesAsJUnit() { // Embedder defines the configuration and candidate steps Embedder embedder = new TestStories(); List<String> storyPaths = new StoryFinder().findPaths(CodeLocations.codeLocationFromClass(this.getClass()),"**/TestStories.story",""); // use StoryFinder to look up paths embedder.runStoriesAsPaths(storyPaths); } @Test(groups={"test"}) public void runClasspathLoadedStories() { // Embedder defines the configuration and candidate steps Embedder embedder = new loginYahoo(); List<String> storyPaths = new StoryFinder().findPaths(CodeLocations.codeLocationFromClass(this.getClass()),"**/loginYahoo.story",""); // use StoryFinder to look up paths embedder.runStoriesAsPaths(storyPaths); }} |
这里可以看出，声明了两个类TestStories和loginYahoo。
TestStories.java
|
1
2
3
4
5
6
7
8
|
public class TestStories extends EmbedderBase { @Override public InjectableStepsFactory stepsFactory() { return new InstanceStepsFactory(configuration(), new TestStep());//设定需要映射的step类 } } |
loginYahoo.java:
|
1
2
3
4
5
6
7
8
|
public class loginYahoo extends EmbedderBase { @Override public InjectableStepsFactory stepsFactory() { return new InstanceStepsFactory(configuration(), new TestLogin());//设定需要映射的step类 } } |
这两个类是一个桥梁的作用，用于设定从story到step的映射，注意这里的两个类是继承类EmbedderBase的，而EmbedderBase类又是Embedder的子类。
这是项目给出的测试类TraderStoryRunner，但是这里有一个问题，就是没有找到运行的入口，点击右键，除了一些maven的操作，并没有其他可以运行的指标，比如junit。
所以通过摸索，按照自己的方法，发现首先要做的就是添加junit测试库，这是必须的。具体步骤：
右键项目->Build path->Configured build path
打开对话框，选择Libraries->Add Library->JUnit,点击next，选择junit4->finished。
添加完Junit后，新建一个Junit测试类
将TraderStoryRunner类的主体方法放进去，命名为Tc.java

至此，这个项目是可以运行起来了。

大体的思路，是将story和step对应起来，将story中的条件、参数传入step对应的类中，如果满足则通过测试，得到then给出的结果，否则得不到理想的结果。
