@Before 不在 java Cucumber Step 中执行

@Before doesn't execute in java Cucumber Step

提问by Peter Wilkinson

I've got a Cucumber Step class that i'm attempting to initialise a page model for all scenarios. So I added a @Before annotated method :

我有一个 Cucumber Step 类，我正在尝试为所有场景初始化页面模型。所以我添加了一个@Before 注释方法：

@Before()
private void beforeScenario() {
    LOGGER.info("Running before!");
    loginPage = BrowserDriver.getPageModel(LoginPage.class);
}

I've then got a bunch of steps that rely on loginPage being set. e.g.

然后我有一堆依赖于 loginPage 设置的步骤。例如

@When("^I click the help link$")
public void I_click_the_help_link() {
    loginPage.clickHelpLink();
}

I have multiple Step classes. Both of the methods above are in the same same Step class. However loginPage is always null. The beforeScenario method is never being called. Have I completely misunderstood how @Before is meant to work? Any tips on how to get what I want to work?

我有多个 Step 类。以上两种方法都在同一个 Step 类中。但是 loginPage 始终为空。beforeScenario 方法永远不会被调用。我是否完全误解了@Before 的工作原理？关于如何获得我想要的工作的任何提示？

Edit : I also have an @After annotated method that does get run after every scenario as expected.

编辑：我还有一个@After 注释的方法，它确实按预期在每个场景之后运行。

1. Make sure you are using cucumber.annotation.Beforerather than org.junit.Before. Cucumber will not process JUnit annotations. (More information in the Scenario Hooks section of this blog post.)

2. Make sure your @Before method is public, not private.

1. 确保您使用的是cucumber.annotation.Before而不是org.junit.Before. Cucumber 不会处理 JUnit 注释。（更多信息请参见本博文的 Scenario Hooks 部分。）

2. 确保您的 @Before 方法是public，而不是private。

There is an accepted answer to this question, but I wanted to point out the comment made by Matt Watson which solved the issue for me and for which I have not seen similar advice elsewhere:

这个问题有一个公认的答案，但我想指出马特沃森的评论，它为我解决了这个问题，我在其他地方没有看到类似的建议：

I've had a play about with some of my cucumber-jvm tests and I think I've spotted it. Your @Beforemethod should be publicrather than private

我玩了一些我的黄瓜 jvm 测试，我想我已经发现了。你的@Before方法应该是public而不是private

The @Beforemethod mustbe public.

该@Before方法必须是public.

Hello I know that is an old post, but none of these solutions work for me. So I'm going to share my solution.

您好，我知道这是一篇旧帖子，但这些解决方案都不适合我。所以我要分享我的解决方案。

I created the class Hooksunder the package: com.mycompany.automation.util

我在Hooks包下创建了类：com.mycompany.automation.util

package com.mycompany.automation.util;

import com.mycompany.automation.rest.database.AS400DBManager;
import cucumber.api.java.After;
import java.sql.SQLException;

/**
 * @author <a href="[email protected]">Julian Mesa</a>
 * @version 0.1.0
 * @since 0.1.0
 */

    public class Hooks {

      @After
      public void beforeScenario() throws SQLException, ClassNotFoundException {
        System.out.print("Closing connection.");
        AS400DBManager.getInstance().closeConnection();
      }

    }

and then I specified the package in the glue options in the runner:

然后我在 runner 的胶水选项中指定了包：

@RunWith(CucumberWithSerenity.class)
@CucumberOptions(
    features = "src/test/resources/features",
    glue = {"com.mycompany.automation.features.steps",
        "com.mycompany.automation.util"}
)

And it worked.

它奏效了。

In my case worked the addition of a package where @Before was defined to the glue parameter:

在我的情况下，添加了一个包，其中 @Before 被定义为胶水参数：

@CucumberOptions(glue = {"cucumber.hook", "cucumber.steps"})

I know this issue is old, but in case somebody runs into the same problem using IntelliJ:

我知道这个问题很老，但如果有人使用 IntelliJ 遇到同样的问题：

Check the "Glue"-Property in your Run/Debug Configuration. This is the list of paths that Glue (the autowirering-system from Cucumber) uses to find Classes to wire.
It seems like IntelliJ is generating this property, if it is not specifically defined in the the Template for "Cucumber Java"-Configs.

检查运行/调试配置中的“胶水”属性。这是 Glue（来自 Cucumber 的自动装配系统）用来查找要连接的类的路径列表。
如果 IntelliJ 没有在“Cucumber Java”-Configs 的模板中专门定义它，则它似乎正在生成此属性。

I don't know how it is generated, but for me the package that contains my class with the Before-Method in question did not exist. After adding it everything worked normally.

我不知道它是如何生成的，但对我来说，包含我的类和有问题的 Before-Method 的包不存在。添加后一切正常。

Found out more background-info. The IntelliJ Cucumber Plugin does not use Junit oder TestNG, but his own implemented runner suite. This runner does NOT interepret the Annotation-Based configurations from Cucumber, only the ones from the Cucumber Property-File or System-Properties. The TestNG-Suite however always overwrites the Glue-Path, not matter if it was actually set or is present. The most consistent way I found was to configure it both using annotations and properties. That way you are always sure that you're config ist used (Gradle-Runner, TestNG-Runner, IntellijCucumber-Runner)

发现更多背景信息。IntelliJ Cucumber Plugin 不使用 Junit 或 TestNG，而是使用他自己实现的运行器套件。此运行程序不解释来自 Cucumber 的基于注释的配置，仅解释来自 Cucumber 属性文件或系统属性的配置。然而，TestNG-Suite 总是覆盖 Glue-Path，不管它是实际设置还是存在。我发现的最一致的方法是使用注释和属性来配置它。这样，您始终可以确保使用了配置（Gradle-Runner、TestNG-Runner、IntellijCucumber-Runner）

I know this Is an old issue but I found a Solution using the 5.5.0 version of cucumber java: I added the Hooks class into the Steps package, having only the glue="Step classpath" and it worked fine for me :)

我知道这是一个老问题，但我找到了一个使用 5.5.0 版本的 Cucumber java 的解决方案：我将 Hooks 类添加到 Steps 包中，只有胶水 =“Step classpath”，它对我来说很好用 :)

Hope that helps!!

希望有帮助！！

In my case, it has worked when I put "dryRun = false" in the Cucumber options.

就我而言，当我在 Cucumber 选项中放置“dryRun = false”时它起作用了。
