问题描述
要在步骤之间传递变量，我有步骤方法属于同一类，并使用该类的字段作为传递的信息。
To pass variables between steps I have the step methods belong to the same class, and use fields of the class for the passed information.
这里是一个示例，如下：
Here is an example as follows:
Feature: Demo
Scenario: Create user
Given User creation form management
When Create user with name "TEST"
Then User is created successfully
带有步骤定义的Java类：
Java class with steps definitions:
public class CreateUserSteps {
private String userName;
@Given("^User creation form management$")
public void User_creation_form_management() throws Throwable {
// ...
}
@When("^Create user with name \"([^\"]*)\"$")
public void Create_user_with_name(String userName) throws Throwable {
//...
this.userName = userName;
}
@Then("^User is created successfully$")
public void User_is_created_successfully() throws Throwable {
// Assert if exists an user with name equals to this.userName
}
我的问题是，在之间共享信息是否是一个好习惯脚步？或者将功能定义为更好：
My question is if it is a good practice to share information between steps? Or would be better to define the feature as:
Then User with name "TEST" is created successfully
推荐答案
为了在步骤之间共享共同点，需要使用。在Java中，它不像在Ruby中那样清晰。
In order to share commonalities between steps you need to use a World. In Java it is not as clear as in Ruby.
引用黄瓜的创建者。
-
场景之间的隔离状态。
Isolate state between scenarios.
在场景中的步骤定义和挂钩之间共享数据。
Share data between step definitions and hooks within a scenario.
此实现的方式是特定于语言的。例如，在ruby中，
步骤定义中的隐式 self 变量指向当前方案的
的World对象。默认情况下，这是
对象的实例，但是如果您使用World钩子，它可以是您想要的任何东西。
How this is implemented is language specific. For example, in ruby,the implicit self variable inside a step definition points to thecurrent scenario's World object. This is by default an instance ofObject, but it can be anything you want if you use the World hook.
在Java中，您有许多（可能是连接的）World对象
In Java, you have many (possibly connected) World objects.
与Cucumber-Java中的World等效的是带有钩子或stepdef批注的所有对象
。换句话说，任何带有
方法并带有@ Before，@ After，@ Given等注释的类，对于每种情况都将被实例化一次
。
The equivalent of the World in Cucumber-Java is all of the objectswith hook or stepdef annotations. In other words, any class withmethods annotated with @Before, @After, @Given and so on will beinstantiated exactly once for each scenario.
此实现第一个目标。要实现第二个目标，您有两种
方法：
This achieves the first goal. To achieve the second goal you have twoapproaches:
a）对所有步骤定义和钩子使用单个类
a) Use a single class for all of your step definitions and hooks
b）使用按责任划分的几个类[1]并使用依赖项
注入[2]将它们彼此连接。
b) Use several classes divided by responsibility [1] and use dependencyinjection [2] to connect them to each other.
选项a）由于您的步骤定义而迅速崩溃代码
变得一团糟。这就是为什么人们倾向于使用b）。
Option a) quickly breaks down because your step definition codebecomes a mess. That's why people tend to use b).
