如何在Spring Boot中的集成测试案例之间完全缓存应用程序上下文？

问题描述

我已经读过SpringBoot测试运行器将在测试类之间缓存上下文。考虑到这一点，我为这种集成测试创建了单个基类

@SpringBootTest
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@ContextConfiguration(locations = "classpath:full-test-app-context.xml")
public class IntegrationTestBase {
....
}

和xml中的简单“全部启动”配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd"
       default-lazy-init="true"
>
    <context:component-scan base-package="helpme">
    </context:component-scan>

</beans>

但是，我运行套件中的所有测试，上下文会多次启动。确实，连续启动花费的时间更少，但是我希望它根本不会发生。

例如，我可以看到横幅蜂鸣的打印时间，多个“应用程序启动”日志以及多个关闭嵌入式数据库上下文的事件。为什么会这样呢？如何实际缓存整个上下文？

在某些测试中，我将@SpyBean用作@MockBean可能会创建新的上下文。我还多次复制了单个测试类，因此测试的上下文完全相同-但仍然没有在这些复制的类之间共享上下文。

上面您可以看到应用程序正在启动多个时间（每个时间都更快），并且@ shutdown mutliple数据库连接池处于shutdown等状态。
