Maven 在没有集成测试的情况下运行单元测试，在没有单元测试的情况下运行集成测试

Question

我有结构：

 - test
   - java
       - com
          - A
             - service
                 - serviceB
                    - DefaultServiceBTest.java
                    - integration
                          - DefaultServiceBIntegrationTest.java

我想单独运行单元测试和集成测试。我正在使用 maven surefire 和 failsafe 插件：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${maven.surefire.plugin.version}</version>
    <configuration>
        <trimStackTrace>false</trimStackTrace>
        <printSummary>true</printSummary>
        <excludes>
            <exclude>integration/*.java</exclude>
        </excludes>
    </configuration>
</plugin>

由于 mvn test 默认运行 surefire:test 具有此配置 maven-surefire 工作，并且使用 mvn test 仅运行单元测试 - 在我的情况下所有测试不在 integration 文件夹中。

但是对于故障安全我有这个配置：

<plugin>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>${maven.failsafe.plugin.version}</version>
    <configuration>
        <includes>
            <include>**/integration/*.java</include>
        </includes>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>integration-test</goal>
                <goal>verify</goal>
            </goals>
        </execution>
    </executions>
</plugin>

针对maven-failsafe 进行此配置并运行mvn verify -Pfailsafe 会导致首先运行单元测试，然后运行集成测试。但是我不希望用这个来执行单元测试。配置有什么问题？

感谢帮助！

首先，您不应该使用不同的目录将单元测试与集成测试分开。使用现有的命名约定。单元测试*Test.java和集成测试*IT.java...

使用以下configuration in your POM File：

<project
    xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>com.soebes.youtube.maven.episodes</groupId>
  <artifactId>example-episode-2</artifactId>
  <version>1.0-SNAPSHOT</version>

通过使用它，您可以通过以下方式运行单元测试：

mvn test

您可以通过以下方式运行单元测试和集成测试：

mvn verify

如果您只想运行集成测试：

mvn verify -DskipUTs
