Consider the case of a useful DSL where you have plenty of scripts that you want to test. Since the cost of writing a DSL is very low, I see this is as a huge benefit. http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment10http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment10Wed, 21 May 2008 18:07:37 GMTMax, Try this, then: Script: specification @vacations: requires @scheduling_work requires @external_connections if UserCount > 50 Tests: with @vacations, Users(51): should_require @scheduling_work should_require @external_connections with @vacations, Users(49): should_require @scheduling_work should_not_require @external_connections http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment9http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment9Wed, 21 May 2008 17:48:53 GMTYou aren't testing the code, you're writing the same program twice :-) Is this really useful? http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment8http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment8Wed, 21 May 2008 17:33:23 GMTCreating testing DSL's is something I just started doing and it has been awesome. I found that there are certain patterns that one tests repeatedly, so this can help. http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment7http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment7Wed, 21 May 2008 14:51:09 GMTThat's a lot more than a 1500% disparity now (yes I know it's just framework code and its not repeated, I'm just being pedantic). I think writing another full on boo dsl for testing something so trivial is a bit extreme. Why not just a base test class? Or some extension methods? "quotes/simple.boo".With("vacations").ShouldRequire("scheduling_work") "quotes/simple.boo".With("vacations").ShouldRequire("external_connections") "quotes/simple.boo".With("scheduling_work").ShouldHaveNoRequirements() Totally breaks AAA, but that's easily fixable. http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment6http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment6Wed, 21 May 2008 13:16:55 GMTNothing much, there isn't an order dependency in the implementation that I wrote for them http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment5http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment5Wed, 21 May 2008 12:55:27 GMTIts kind of nice. You have to write a TestDSL engine to test your dependencies on your DSL script. What happens if you shuffle the should_require statements? http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment4http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment4Wed, 21 May 2008 12:34:50 GMTQuis custodiet ipsos custodes? http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment3http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment3Wed, 21 May 2008 11:37:03 GMTAre you going to test this new DSL with itself? http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment2http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment2Wed, 21 May 2008 11:33:08 GMTNice, but how are you going to test that the testing DSL works? ;) http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment1http://ayende.com/3329/create-a-test-dsl-to-test-the-dsl#comment1Wed, 21 May 2008 11:31:24 GMT
