Hi Jay,
I quite like this way of working its nice and clean and each test demonstrates
exactly what you expect to be invalid and why
def setup
@va.lid_attributes = {
:parents => 1
:children => 1,
:family_clam => 1,
:campsite => 'blah',
:total => 100,
}
end
def test_valid
cart = Cart.create(@valid_attributes)
assert cart.valid?
end
def test_valid_if_children_is_nil
cart = Cart.create(@valid_attributes.merge(:children => nil)
assert cart.valid?
# or
assert cart.errors.on(:children).nil?
end
def test_invalid_if_total_is_nil
cart = Cart.create(@valid_attributes.merge(:total => nil)
assert ! cart.valid?
assert cart.errors.on(:total)
end
I hope this helps.
