Provide support for session/request scoped beans for integration testing [SPR-4588]

[spring-projects-issues]

David J. M. Karlsen opened SPR-4588 and commented

Overview

It would be very handy if Spring could provide support for session and request scoped beans for integration testing (e.g. in the TestContext framework).

There's also a thread on the forum related to this: http://forum.springframework.org/archive/index.php/t-40257.html .
We're getting around it by using a prototype instead during testing (or just inserting a bean ourselves) - but I'd prefer a OOTB solution.

Did I hear a fix-version 2.5.3? ;-)

This discussion is relevant and points on some ways to solve this: http://forum.springframework.org/showthread.php?t=27933

Attached is a somewhat naive approach which could be further refined.

There's a forum thread showing a solution that works with Spring TestContext and uses a custom context loader in @ContextConfiguration, see: http://forum.springsource.org/showthread.php?t=50722&page=2

Spring Batch uses a custom TestExecutionListener to test step scoped components: http://static.springsource.org/spring-batch/reference/html-single/index.html#d0e7538 A similar approach for session and request scopes would make sense?

Sam Brannen commented

GitHub commit 21ebbb9c02 introduces RequestAndSessionScopedBeansWacTests which verifies support for request and session scoped beans in the Spring TestContext Framework (TCF).

This support was actually introduced as an intentional side effect of the work performed for #9917 through the addition of the new ServletTestExecutionListener.

Attached file has non-static @BeforeClass method, which JUnit 4.11 doesn't accept. But it's not possible to make it static, because it uses non-static applicationContext.

Dzmitry Lazerka, that's correct: the code in the AbstractJUnit4SpringWebContextTests attachment does not work, but fear not: this issue was resolved in October 2013. Thus, there is no need for such custom solutions beginning with Spring Framework 3.2.

Please see the Testing request and session scoped beans section of the reference manual for details.
