我是新的 Jbehave。我试图找到一种通过 Jbehave 实现黄瓜世界的方法。我使用 jbehave 和 pico 原型生成了项目。我试图并行运行两个故事。我将 pom.xml 中的线程更新为 2。考虑如下示例 stepdef 类

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 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 MyStories 类，它扩展了 JUnitStories，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，它们会成功。当我并行运行故事时，它们失败了。

我找不到有关如何与 Jbehave 和 pico 并行运行测试的文档。此外，我需要在我的 stepdef 类之外有一个模型，因为我将拥有多个共享同一个模型实例的 stefdef 类。

在阅读更多内容并尝试使用 Spring 的 Jbehave 之后，1. 我认为没有办法让每个线程创建不同的 stepdef 实例。2. 在 Jbehave 中，没有相当于 cucumber 的world线程安全对象。

正如@VaL 在问题的评论中提到的那样，我们必须明确地使 thinks 线程安全。

这是我目前的理解。如果有更好的方法 - 请告诉我。
