Creating generator tests

rubyonrails-core
1

I want to go in and improve the default scaffold (ex resource_scaffold) a bit and noticed the lack of tests for generators.

So I thought I'd give people a heads up that I'm working on creating initially tests for the scaffold generator as well as test helpers to make it simpler to test generators in the future. I'll probably go through and create tests for the built in generators as well eventually.

I have a question about layout. I'm currently placing the scaffold tests in:

railties/test/rails_scaffold_generator_test.rb

Does that make sense naming wise? So afterwards there could be:

railties/test/rails_model_generator_test.rb etc.

I've also created the test helpers in

railties/test/generator_test_helpers.rb

Does that follow convension or should I rather put them somewhere else, to make it easier for say plugin developers to use them?

Finally as part of my testing I build up a very basic rails directory structure under railties/test/fixtures/tmp and then delete it again in the teardown. I have seen similar things done in the tests from various plugins and it works, can anyone see any issues with that?

Sounds great, Pelle.

how about a test subdirectory, like railties/test/generators/*

Nope. All good.

OK. I've uploaded my patch with the scaffold generator tests at:

http://dev.rubyonrails.org/ticket/8443

It also includes a generator_test_helper module, which has lots of helpful assertions, which could be used for testing most kinds of generators.
