在 maven 中测试运行不清理 DBUNIT 数据库

Question

我正在使用以下依赖项来进行 dbunit 测试

        <dependency>
            <groupId>org.dbunit</groupId>
            <artifactId>dbunit</artifactId>
            <version>2.4.9</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.hsqldb</groupId>
            <artifactId>hsqldb</artifactId>
            <version>2.3.4</version>
            <scope>test</scope>
        </dependency>

测试运行在 inteliJ 中一次又一次地完美，但是当我运行在命令行上进行测试时，它总是失败，在我的测试中加载第二个测试时出现外键约束错误class

我试过从 HSQL 切换到 H2，反之亦然，这两个数据库都出现了同样的问题。然而，运行 InteliJ 中的测试再次完美运行。在 Maven 中运行ning 不断抛出错误。我在这里错过了什么我完全迷失了为什么它不起作用

Answer 1

我找到了...退后一步，重新思考，我发现默认情况下运行s paralell 中的解决方案 maven 测试方法。如果您将 Maven 限制为仅运行类 in paralell 我能够修复它

<build>
    <finalName>voertuigbeheer-web</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <configuration>
                <parallel>classes</parallel>
            </configuration>
        </plugin>
    </plugins>
</build>

这是一个非常烦人的"feature"追踪！
