Is there a way of implementing callback methods for cucumber in java?
问题
我最近遇到一个需求，在执行测试步骤之前需要进行一些预处理。我必须同时为JUnit 5（使用Jupiter引擎）和Cucumber测试框架进行这样的预处理。我已经为JUnit 5做了相同的处理（因为它支持扩展），使用了BeforeEachCallback并且使用了@extendWith注解。
但是我在如何为Cucumber做相同处理方面遇到了困难。在Cucumber中是否有一种方法可以注册一个回调方法，在调用每个步骤之前调用该方法？我知道有@Before钩子，但我希望这个方法是通用的，会在所有特性的每个步骤之前被调用。
类似于下面的代码：
public void preProcessor() {
// 这个方法应该在每个步骤之前被调用
// 通过方法上下文，我指的是目标方法的名称（在JUnit中，我可以轻松地从context.getTargetMethod()中获取它）
}
有没有人能给我一些关于上述内容的方向或想法呢？
英文:
I recently came to a requirement where I have to do some preprocessing before test steps. I had to do this for both JUnit 5 (with Jupiter engine) and cucumber framework. I had done the same for JUnit 5 (as it supports for extension) using BeforeEachCallback and using @extendWith annotation.
But I am struggling in how to do the same for cucumber. Is there a way in cucumber by which I can register a callback method which will be called before every step is invoked? I know about @Before hooks but I want this method to be a common and generic one which will be called before every step for all features.
Something like below:
public void preProcesser() {
//This method should be called with method context before each step
//by method context I mean the targetMethod name (in JUnit I can easily get it from context.getTargetMethod()
}
Can anyone give me some direction/idea on the above please?

可以，在特性文件的开头添加一个 Background 步骤，该步骤充当前提条件，并在所有后续场景之前运行。
@Tag
Feature: 测试特性
Background: 前提步骤
Given 执行某项任务
Then 导航到主页
Scenario: 测试场景
Then 执行其他测试
...
所有场景的执行流程将是：
Given 执行某项任务
Then 导航到主页
Then 执行其他测试
英文:
Yes, you can add a Background step at the beginning of the feature file and that step acts as a prerequisite and runs before all the following scenarios.
@Tag
Feature: Test Feature
Background: Prerequisite step
Given I perform some task
Then navigate to home page
Scenario: Test Scenario
Then I perform other tests
...
The execution flow for all your scenarios will be -
Given I perform some task
Then navigate to home page
Then I perform other tests
