在不同的Spock测试中重用Spring应用程序上下文

Question

I would like to reuse the same Spring context across several integration tests written in Spock framework. According to the documentation context caching is based on classes property of @ContextConfiguration annotation.

That's an example test:

@SpringBootTest
@ContextConfiguration(classes = Application.class)
class ExampleIntegrationTest extends Specification {

    def 'should reuse Spring context if already created'() {
        expect:
        1 == 1
    }
}

The second test also contains the same @ContextConfiguration annotation, ie

@ContextConfiguration(classes = Application.class)

but when I run all tests I can see in the console that Spring context is created per each test. I would like to cache it between different tests. Am I missing something? Basically, I would like to achieve the same thing as described here (stackoverflow question) but in Spock instead of JUnit.

Context Caching is done by the Spring Framework, it follows the rules described here , ie, it builds a context cache key factoring in different factors. As long as all of them are the same, it reuses the same context.

• locations (from @ContextConfiguration)
• classes (from @ContextConfiguration)
• contextInitializerClasses (from @ContextConfiguration)
• contextCustomizers (from ContextCustomizerFactory)
• contextLoader (from @ContextConfiguration)
• parent (from @ContextHierarchy)
• activeProfiles (from @ActiveProfiles)
• propertySourceLocations (from @TestPropertySource)
• propertySourceProperties (from @TestPropertySource)
• resourceBasePath (from @WebAppConfiguration)

Spock supports @SpringBootTest or any of the other Spring Boot test annotations, such as @WebMvcTest , directly and you should not add an explicit @ContextConfiguration(classes = Application.class) .
