我应该将Junit @Category的接口类放在哪里?

问题描述

我想定义项目范围的接口，以在@Category批注中使用，并配置Maven以在构建整个项目时排除其批注的测试.

I'd like to define project-wide interfaces, to be used in @Category annotations, and configure Maven to exclude their annotated tests when building the whole project.

在 application 项目中，有一个我要分类的测试:

In the application project there's a test I'd like to categorize:

@Category(Integration.class)
@Test
public void testExternalResource() { ... }

设置:

我已经建立了一个多模块的Maven项目:

The setting:

I've set up a multi-module maven project:

/container (has a pom with <modules> element)
    /parent (all other modules inherit from its pom. has no source, only pom)
    /util (other modules are depending on it)
    /infra
    /application (depending on infra and util, inherits from parent)

作为基础设施狂:)，我想将我的整个项目配置为排除任何模块中的组.因此，在 parent 模块中，我定义了:

Being an infrastructure freak :), I'd like to configure my whole project to exclude groups in any module. So, in parent module I've defined:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
         <excludedGroups>com.mycompany.test.Integration</excludedGroups>
    </configuration>
</plugin>

我已经将Integration接口放在 util 模块(在util/src/test/java中)中，所有模块都可以看到:

And I've put the Integration interface in the util module (in the util/src/test/java), for all modules to see:

package com.mycompany.test;
public interface Integration {}

并且因为它是test-jar，所以我已进行了正确的配置对于 util 和 application .

And because it's a test-jar, I've made the right configuration for both util and application .

运行mvn clean install时，我得到了

[ERROR] Failed to execute goal org.apache.maven.plugins:
    maven-surefire-plugin:2.16:test
    (default-test) on project util: Execution default-test of goal
    org.apache.maven.plugins:maven-surefire-plugin:2.16:test
    failed: There was an error in the forked process
[ERROR] java.lang.RuntimeException:
    Unable to load category: com.mycompany.test.Integration

当然，该类不可用-我在项目的第一个模块的测试罐中塞满了它. :(

Well, of course the class isn't available - I've crammed it in a test-jar in the first module of the project. :(

我应该在哪里放置我的Integration界面，以便其对我的mvn配置和我的源代码可用?

Where should I put my Integration interface so it will be available to my mvn configuration and my source code?

推荐答案

创建一个新的Maven模块并将该接口放在src/main/java/下.确保junit可用作编译时依赖项(<scope>compile</scope>)-您基本上是在构建其他测试可以使用的依赖项.因此，像往常一样，在其他测试进入src/test/java时，必须将有助于其他测试的代码放入main中.

Create a new Maven module and put the interface under src/main/java/. Make sure junit is available as a compile time dependency (<scope>compile</scope>) - you're basically building a dependency that other tests can use. So your code that helps other tests must go into main while the tests for this go in the src/test/java, as usual.

这一步感觉有点奇怪，但是请考虑如何打包junit本身.从junit的角度来看，它只是一个普通的Java库，因此其所有代码都放入了main.

This step feels a bit weird but think about how you would package junit itself. From the point of view of junit, it's just a normal Java library, so all its code goes into main.

当您需要此模块时，可将其用作<scope>test</scope>

When you need this module, use it as a test dependency with <scope>test</scope>
