Test::Unit and class attributes

ruby-talk
1

Hi,

I have a test class the inherits from Test::Unit::TestCase.

If I create a setup and teardown method

def setup
  Browser.start
  log_in
end

def teardown
  log_out
  Browser.close
end

# and create class attributes here

@search = "Employee was created successfully"

they are not seen in my test method ...

def test_ST_MSE_4

  enter_employee
  click_submit
  assert($ie.contains_text(@search))

end

But if I put the class attributes in the setup method, they are seen by
my test(s).
Is it normal practice to enter your class attributes in the setup
method?

Thank You

Yup.

A class that derives from Test::Unit::TestCase is still just a normal
class. Normal classes don't follow what you seem to expect of a
test_case derived class.

Consider...

class Foo
  @foo = 123
  def bar
    p @foo
  end
end

Foo.new.bar
#=> nil

The instance of Foo that we create can't see the class instance
variable (@foo = 123).

You could change the bar method to..
p self.class.instance_variable_get(:@foo)

but I'd guess you don't want to do that.

Hope this helps,

Chris
