java – 没有缓存Spring ApplicationContext用于与Maven的集成测试

当集成测试从IDE启动时,ApllicationContext只加载一次,然后在测试之间共享,并且它按预期工作.但执行mvn clean install每次测试都会创建新的ApllicationContext.根据Spring doc我配置了
maven-failsafe-plugin使用单叉

要缓存ApplicationContext,请使用以下注释：

@ContextConfiguration(classes = TestConfig.class)

使用maven构建应用程序时为什么不共享上下文？
实际上有没有其他方式加速IT测试？谢谢.

更新：

这是多模Maven项目. Accordig Spring IT caching doc

To benefit from the caching mechanism,all tests must run within the
same process or test suite. This can be achieved by executing all
tests as a group within an IDE. Similarly,when executing tests with a
build framework such as Ant,Maven,or Gradle it is important to make
sure that the build framework does not fork between tests. For
example,if the forkMode for the Maven Surefire plug-in is set to
always or pertest,the TestContext framework will not be able to cache
application contexts between test classes and the build process will
run significantly slower as a result.

所以对于maven-failsafe-plugin 2.14,这个配置等于forkMode =一次

最佳答案

您可以尝试使用指定的上下文位置而不是类：

@ContextConfiguration(locations = "classpath:test-context.xml")

Spring按位置属性缓存应用程序上下文,因此如果第二次出现相同的位置,则Spring使用相同的上下文而不是创建新的上下文.

UPDATE

您的项目是多模块Maven项目吗？
相应的文档：

The default setting is forkCount=1/reuseForks=true,which means that Surefire creates one new JVM process to execute all tests in one maven module.
