Hi, If I have this line in my model: validates_presence_of :name, :message => "Please enter a name" and I test this with the following code: def test_should_require_name user= User.new(valid_user_attributes(:name => "")) assert !applicant.save end Is there a way to write an additional test to ensure that not only the name field may not be blank, but that if it is blank the message "Please neter a name" is thrown? Many thanks -- Posted via http://www.ruby-forum.com/.
Yep try... def test_should_not_be_valid_without_name user = User.new user.valid? assert_equal user.errors.on(:name), "Please enter a name" end
Hi, That worked perfectly. Thank you very much. -- Posted via http://www.ruby-forum.com/.
You''re welcome. Just a little advice - It''s generally better practice to be more specific with the names of your tests. I find it helps define exactly what it is you''re testing for. Here''s an article about BDD if you''re interested: http://dannorth.net/introducing-bdd
> Here''s an article about BDD if you''re interested: > http://dannorth.net/introducing-bddHey, cool article. Thanks a lot. I will read that through this evening. I''m still a bit new to TDD and am still finding my way around, so thanks for the advice. -- Posted via http://www.ruby-forum.com/.
I''d also recommend checking out rspec.
It''s a BDD framework that helps you write tests that feel a lot more
intuitive than the default rails testing suite.
simply install the rspec gem and the rspec-rails gem
Specs are written like:
describe User do
it "should not be valid without a name" do
user = User.new
user.valid?
user.errors.on(:name).should == "can''t be blank"
end
end
Hope you find that useful

> Hope you find that useful > :)Thanks for the tip. I''m currently reading a book "Professional Webdevelopment with RoR2" by Jens-Christian Fischer and he''s just getting into Rspec. I wasn''t sure how indepth I should read that part, but now I will definitely take the time to check it out. -- Posted via http://www.ruby-forum.com/.
