Description
After updating Mocha from version 2.1.0 to 2.2.0, a test began to fail with the following output:
$ bin/rails test test/unit/issue_test.rb:704 Run options: --seed 38306 # Running: F Failure: IssueTest#test_assigning_attributes_should_assign_project_and_tracker_first [app/models/issue.rb:478]: unexpected invocation: subject=(Test) bin/rails test test/unit/issue_test.rb:704

- Category changed from Gems support to Code cleanup/refactoring
Below is the test code that currently fails. The three lines of issue.expects expect that the three methods :project_id=, :tracker_id=, and :subject= are called in this order. However, it is :subject= that is called first because issue.attributes = {:subject => 'Test'} is executed first. It is curious that this code worked with Mocha 2.1.
def test_assigning_attributes_should_assign_project_and_tracker_first
seq = sequence('seq')
issue = Issue.new
issue.expects(:project_id=).in_sequence(seq)
issue.expects(:tracker_id=).in_sequence(seq)
issue.expects(:subject=).in_sequence(seq)
assert_raise Exception do
issue.attributes = {:subject => 'Test'}
end
assert_nothing_raised do
issue.attributes = {:tracker_id => 2, :project_id => 1, :subject => 'Test'}
end
end
The error can be fixed simply removing issue.attributes = {:subject => 'Test'}.
