    JBehave

    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：

    1. Write story
    2. Map steps to Java
    3. Configure Stories
    4. Run Stories
    5. View Reports


    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

    loginYahoo.story：
    Narrative:
     
    In order to show the yahoo function
    As a user
    I want to login yahoo
     
    Scenario: normal login
     
    Given yahoo login address by.bouncer.login.yahoo.com
    Then print successful

    　　

    另一个是模拟浏览的story:

    TestStroies.story：
    Browse Etsy.com
     
    Meta:
    @category browsing
    @color red
     
     
    Narrative:
     
    In order to show the browsing cart functionality
    As a user
    I want to browse in a gallery
     
    Scenario: Browsing around the site for items
     
    Given I am on localhost
    Then 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
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    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
    2
    3
    4
    5
    6
    7
    8
    9
    10
    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

    23
    24
    25
    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

    12
    13
    14
    15
    16
    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

     @Before
     public void setUp() throws Exception {
     }
     @After
     public void tearDown() throws Exception {
     }
      
     // @Test : 表示这是一个测试用例，只有标识了改符号的函数才会被执行测试
     
     @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
     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);
     }
    }

    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。
