Already got something like that. The main difference, is that I'm using
factories.
The problem with my test, which almost follow those examples, is that I'm
repeating myself each time I want to validate the same (uniqueness, length,
etc).
One option is to create methods for each type of validation and that way the
test will be DRY. Instead of that I was looking if there is a gem that
provide me with those (keep them updated, etc).
At that point is when I found shoulda-matchers.
Otherwise this is an example of how the test looks
class User < ActiveRecord::Base
...
validates :first_name,
:presence => true,
:length => { :maximum => 32 }
validates :last_name,
:presence => true,
:length => { :maximum => 32 }
...
end
According to the examples your tests for those fields should been:
describe User do
before(:each) do
@attr = { :first_name => "Foo", :last_name => "Bar" }
end
...
it "should require a first name" do
no_email_user = User.new(@attr.merge(:first_name => ""))
no_email_user.should_not be_valid
end
it "should require a last name" do
no_email_user = User.new(@attr.merge(:last_name => ""))
no_email_user.should_not be_valid
end
it "should reject first names that are too long" do
long_first_name = "a" * 33
long_first_name_user = User.new(@attr.merge(:first_name =>
long_first_name))
long_first_name_user.should_not be_valid
end
it "should reject last names that are too long" do
long_last_name = "a" * 33
long_last_name_user = User.new(@attr.merge(:last_name =>
long_last_name))
long_last_name_user.should_not be_valid
end
end
