Anyone know how to stub Kernel#open? I''m trying to mock/stub an open-uri call, but it doesn''t seem to like it. Here''s the test code, and the failures: body = File.open(File.dirname(__FILE__) + ''/../fixtures/google_search_california.html'').read

Hello all, I''m having difficulty setting up mocks such that I can verify that Rails was going to render the right template file (for example new.rhtml) and stop Rails from performing the actual rendering. After peeking at Rails'' internals, I tried two techniques as illustrated here: http://pastie.caboo.se/18197 Neither worked. I think the first one failed because Rails

Hi :) Does anyone know of a way to set the value of $? ? I have a test which stubs ` ; the call works fine, but then the library I am testing checks the value of $? to see if the process terminated correctly. It seems not to be possible to assign $? directly... For now I do this before my test : `ls > /dev/null` Which ensure that $? is zero ; but this is not a very nice way of doing it !

I have seen some basic examples of using Mocha and Stubba with ActiveRecord Models; However, the ones I read were somewhat simplistic. That is they stubbed the find class method of the model, or the execute method of the connection object. While stubbing the find method had the desired effect for the author it did not help with a situation I was hacking away on. Which was writing a test case

To: James Mead <jamesmead44 at gmail.com> Hey James, Sorry to bug you. I was curious how you''d handle a call to exec in a method you were testing. Kernel.stubs(:exec)... doesn''t seem to work but I''m not sure where else an

I''ve finally managed to find some time to do some serious work on Mocha. There are some code snippets on my blog (http://blog.floehopper.org/articles/2007/04/12/preview-of-latest-mocha-changes) showing the new functionality available in trunk (revision 128). I don''t don''t know how many people out there are using trunk, but it would be great to get some feedback on these

Hi guys, I''m running mocha (0.3.2) against Rails core and just found an issue where the mock doesn''t go away after the test is run. For example: def test_reset_bang_doesn_reinstall_named_routes ActionController::Routing::Routes.named_routes.expects(:install).never @session.reset! end def test_zzz puts ActionController::Routing::Routes.named_routes.inspect

I''ve always wanted to be able to do stuff like this in my functional tests c = customers(:customer_1) c.expects(:great_customer_service) post :service_customer, :id => c.id This of course fails because inside the rails action a different instance of customer is used. Some of the time setting your expectation/stubbing on Customer.any_instance works, but it''s not

Hey all, I have a question with using mocha in my tests. In the same test file, I have two tests, <code> def test_a klass.any_instance.stubs(:method_name).returns("something") klass.new.method_name ... end def test_b ... klass.new.method_name ... end </code> where klass is some class when the tests run, test _a passes, but test_b had an error like this:

I''m pushing a major overhaul in testing the Rails codebase. Mocha and stubba make my life easy so that''s what I''m using. The first major patch using them is in RailTies (http://dev.rubyonrails.org/ticket/5970) now. I spoke to DHH today about using it in the other libraries and I think it''ll be ok, but they really want to include as little code as needed. I

Hello! I''m new to Mocha and through experimentation I found out something that is not explicitly stated in the documentation: If you need to mock the same function call with different parameters and results, you can set the scope of expectations with a begin ... end block. I also made up an example on how to expect more than one function call with different parameters and return values.

Hello, I''ve just started using Mocha in the tests for my Rails app, and I''ve run across an issue with mocking a method that should be called with different parameters. How would I setup a mock that expects that a method will be called once with no paramaters, and a second time with a parameter? I''d be tempted to shortcut and just do something like

Hi, I''m new to mocha and stubba but eager to learn. I have a rails functional test in which I would like to stub an instance method of particular class to always return true. I tried the following: def test_post_checkout Order.any_instance.stubs(:successful?).returns(true) post :checkout assert_response :redirect assert_equal "Checkout was successful.",

I''ve just been tying my brain in knots looking at bug #8687 ( http://rubyforge.org/tracker/index.php?func=detail&aid=8687&group_id=1917&atid=7477 ). I''ve been (1) trying to work out whether there is anything logically wrong with Mocha''s existing behaviour and (2) whether Mocha should support the requested functionality. It all centres around the use of the

Right now I''m working on adding tests to a method that looks like this: def get_via_redirect(path, args={}) get path, args follow_redirect! while redirect? status end So, I want to confirm that get is called and that status is returned but I also want to see that when the value of redirect? effects how many times follow_redirect is called. Is there

* Hamcrest-style parameter matchers * Values returned and exceptions raised on consecutive invocations * Yields on consecutive invocations * Multiple yields on single invocation * Invocation dispatch fixed * Deprecated returning result of a Proc -- James. http://blog.floehopper.org

Did any further discussion ever come of this? I take it is officially not supported currently? I just get an odd error when I try it (it throws a "0 expected 1 received", no matter what stubbing/expectation combo I use), so came looking around on google, and finally the mailinglist. Here''s my stripped down example: http://pastie.caboo.se/145603 (it fails with expects too)

Hi guys, Would you mind if I ask how Flex Mock and Mocha sit together? They compete directly? I read that Flex Mock was built into Rails 1.2. Is there a reason to use Mocha instead of Flex Mock? Tks Greg

Hi all, We just updated to the latest version of Mocha and now we''re seeing a lot of odd test failures. If this isn''t the appropriate place for a question like this, please let me know. Say I have code like this in a controller: DataMonitor.toggle_notification! And I mock it like this: DataMonitor.any_instance.stubs(:toggle_notification!) This would work fine with Mocha

I find that a lot of times I want to ensure a method gets called exactly once, for example when testing caching or eager loading. What does the list think of adding this little humane method to Mocha::Expectation? def once times(1) self end which means this: def test_should_only_grab_post_once_from_the_cache Post.expects(:get_cache).with(google_vs_yahoo.id).times(1)
