使用Jbehave和pico (Jbehave Pico)并行执行

Question

我是新来的。我正在试图找到一种方法来实现黄瓜与Jbehave的世界。我生成了带有jbehave和pico原型的项目。我正在尝试并行运行两个故事。我将pom.xml中的线程更新为2。

public class PojoSteps {

    public Pojo pojo;

    public PojoSteps(Pojo pojo){
        this.pojo = pojo;
        System.out.println(" @@" + new Timestamp(System.currentTimeMillis()) + " * this is " + this + ". In PojoSteps constructor. Pojo created is:" + this.pojo + ". Thread = " + Thread.currentThread().getId());
    }

    @Given("I have a pojo with $i")
    public void iHaveAPojoWith1(int i){
        pojo.setI(i);
        System.out.println(" @@" + new Timestamp(System.currentTimeMillis()) + " * this is " + this + ".In iHaveAPojoWith1. pojo = " + this.pojo +". Value of To be set = " + i +". Value set Pojo.getI() = " + this.pojo.getI() + ". Thread = " + Thread.currentThread().getId());
    }

    @When("I wait for some time")
    public void randomWait() throws InterruptedException {
        Thread.sleep(new Random().nextInt(200));
    }

    @Then("my pojo should still have $expectedi")
    public void myPojoShouldStillHave1(int expectedi){
        System.out.println(" @@" + new Timestamp(System.currentTimeMillis()) + " * this is " + this +". In myPojoShouldStillHave1. pojo = " + this.pojo + ". expected = " + expectedi + ". actual = " + this.pojo.getI() + ". Thread = " + Thread.currentThread().getId());
        Assert.assertEquals(this.pojo.getI(), expectedi);
    }
}

我有如下的Pojo模型

  public class Pojo {

    private int i;

    public void setI(int i){
        this.i = i;
    }

    public int getI(){
        return this.i;
    }
}

我的两个故事如下PojoOne.story

    Scenario: scenario description
       Given I have a pojo with 1
       When I wait for some time
       Then my pojo should still have 1

PojoTwo.story

 Scenario: random description
     Given I have a pojo with 2
     When I wait for some time
     Then my pojo should still have 2

我有一个扩展JUnitStories的MyStories类，如下所示

public class MyStories extends JUnitStories {
   ....
       private PicoContainer createPicoContainer() {
        MutablePicoContainer container = new DefaultPicoContainer(new Caching().wrap(new ConstructorInjection()));
        container.addComponent(PojoSteps.class);
        container.addComponent(Pojo.class);
        return container;
    }
 }

当我不并行运行故事时，它们就会成功。当我并行运行故事时，它们是失败的。

我找不到关于如何与Jbehave和pico并行运行测试的文档。此外，我需要在stepdef类之外有一个模型，因为我将有多个stefdef类，它们将共享相同的模型实例。

Answer 1

在阅读了更多的内容并尝试了Jbehave with spring之后，1.我认为没有办法为每个线程创建不同的stepdef实例。2.在Jbehave中，没有等同于cucumber的world对象的threadsafe。

正如@VaL在问题的评论中提到的，我们必须显式地使threadsafe。

这是我到目前为止的理解。如果有更好的办法--请让我知道。
