Stubbing a class breaks previous test

I’m following along in the book (great stuff, by the way). In section 7.2 on page 117 (B7.0), once I add the lets stub a class test in test/unit/project_test.rb, it breaks the first test, should be able to retrieve projects based on <a href="mailto:day”>day@. The error message is as follows:

  1) Failure:
test_should_be_able_to_retrieve_projects_based_on_day(ProjectTest) [test/unit/project_test.rb:8]:
<["2009-01-06", "2009-01-07"]> expected but was
<[]>.

If I remove the lets stub a class test, none of the other tests fail. I think it may have something to do with overriding the find method, but I didn’t think stubbing a method in one test would affect other tests.

I posted a gist of my project_test.rb file here. My environment includes the following:

• rvm 1.0.11
• ruby 1.9.2-p0
• rails 3.0.0
• factory_girl 1.3.2
• mocha 0.9.8
• sqlite3-ruby 1.3.1

I placed require 'mocha' in test/test_helper.rb.

Has anyone else experienced this problem?

Yes, I am experiencing the same problem. Were you able to resolve this? It seems to me like stubs or mocks are global when declared in an individual test.

You need to update your Gemfile so that mocha is not required automatically. Update the mocha gem declaration so that it looks like this:

gem ‘mocha’, :require => false
