Presentation: System Integration Testing with Spring

by Floyd Marinescu on Aug 03, 2007 |
Not only does Spring provide you an application configuration framework, it provides a holistic solution that makes your application's use cases and subsystems easier to test.  The emphasis is on testing outside a JEE server or container, thus greatly improving productivity.   In this presentation, recorded at The Spring Experience, Spring Creator Rod Johnson discusses integration testing and the support that Spring provides for it, issues around testing the persistence layer, and how to test web apps.

Watch System Integration Testing with Spring (82 min)

The presentation will include a demo showing how an application can be tested as it is developed without developers needing to wait for JEE container startup and deployment.   In the presentation Rod presents some of the unique features Spring has to facilitate testing:
  • Dependency Injection
  • Data access and transaction management
    • Automatic transaction creation and rollback
  • No need for setup/teardown scripts
    • Automatic rollback after each test method
    • Can be run directly from IDE
  • Context Caching + Auto-rollback = Rapid performance for better productivity
    • 100s of tests per minute
  • Integrated with other data access code and testing Spring configuration and other Spring code
    • Enables validation of triggers, sequences, stored procedures and JDBC code
  • Context caching between many test cases
    • Particularly important with Hibernate due to the cost of SessionFactory creation
    • Uses static Map to prevent loss of built configuration when JUnit destroys and reinstantiates test classes
  • Dependency injection of test cases to avoid the need for any glue code in tests
    • Focus on testing your mappings and queries, with minimal distraction from test setup
  • Zero changes required in DAOs or other application Java code between test and deployment

Slides to download by Adelino Rodrigues

Would it be possible to have a URL with the slides to download?

Re: Slides to download by Wu Marshal

yes

I really enjoyed the first 40 minutes by Laurent Ploix

...because you basically cover the basics of a good testing approach, with or without java, with or without Spring. Even people who don't use Java can listen to this conference - at least the first half -.

Wrong tool for UI unit tests by Marc Guillemot

Rod,
I fear that your knowledge of UI unit test tools is outdated: HttpUnit is a dead project (or at least deeply asleep). This is the reason why we've moved to HtmlUnit for over 3 years in Canoo WebTest.
HtmlUnit is also the default underlying layer used by jWebUnit (that you mentionned).
Your assertion concerning limited js support is not fully correct either.

Nevertheless all these tools are too low level and for instance junit like reports are too limited for UI tests. Have a look at WebTest tests written as unit tests in Groovy (just like what Grails can generate). This allows you to use the higher level API of WebTest and have reach reports just from your unit tests. This makes a real difference what concerns the maintainability.

Excellent presentation! by Igor Kolomiets

All these years I was blaming myself for being lazy and still using real db with transaction-wrapped test methods (with auto-rollback at the end) for testing DAO layer. I thought that best practices require using in-memory db (for speed) and using full-blown db data-fixture setup/cleanup steps before and after running each step (approach heavily advocated by ROR for example). The only reason I didn't go that route is the lack of immediate benefits. Now it's such a relief to hear from respected authority like Rod that it's a "good thing" :)

Re: Wrong tool for UI unit tests by anjan bacchu

Hi Marc,

Thanks for updating the http/html unit testing scenario.

Can you update with some links so that others can get a quick overview ?

Thanks ,

How to download?

Rollback Transaction by Rodolfo Rothganger

Very usefull presentation!

One small point: a complete test (not a Unit Test...) should check for failures during the transaction commit phase, including problems on a two phase commit scenarios.

Rudolf

Re: Wrong tool for UI unit tests by Alexandre Poitras

Is it possible to use those UI unit tests tools in a EJB 2.x application ? Or I need to mock every ejbs?

Re: Slides to download by Patricia Guimaraes

I listened to this talk and thought it was excellent! I would very much like to get a copy of the slides. Could you provide instructions on how to do that? Previous postings state that it is possible, but don't say how.

Thanks a lot,

Pat

Hi,

First of all , Thanks a lot Rod, for these wonderful slides :))

Thanks to company firewall policies, Not all of us in the team have privileges to view *.swf content.

So I used this Javascript snippet to view all Slides at once,

[and then , If Using IE,go to "Temp Internet Folder" (or appropriate cache/store folder of browser) and copy swf files from there to Local Disk :))
]

Then shared these slides with my team here in my office, and Even they are very thankful to you Rod :)

Re: Slides to download by Prashant Bhate

Hi,

First Of All, Thanks a lot Rod for the wonderful slides & Presentation :)

Only Problems with the slides is the format i.e. *.swf. Not everyone has the privileges in My team to view flash content. [Thanks to company's Firewall policies].

So I have Used this scriptlet to view all slides at once, and then Copied cached slides [From "Temp Internet Folder" if using IE or any other browsers' store floder] to Disk. Then I shared it with my team. Now they can watch it offline and Even my colleagues and team members are very greatful to you ;)
