Hi,

Is there any way to loop TEST::UNIT test cases to accommodate  
different data values?

class Test\_Class \< Test::Unit::TestCase

def test\_1

end

def test\_2

end

end

Thanks

Aidy

Can you explain a bit more?  
normally people use:

class FoobarTestClass \< Test::Unit::TestCase  
def test\_for\_bar  
\<\>.each do  
#your assertions here  
end  
end

Hi,

I am still thinking about this, but I hope you get the idea

class TC \< Test::Unit::TestCase  
@@test = Test\_Data.new

def setup  
@browser = Browser.new  
@browser.goto(test.data[:url])  
login = Login.new(@@test.data[:username], @@test.data[:password])  
login.sign\_in.click  
end

def teardown  
application.log\_out.click  
@browser.close  
end

def test\_case\_1

```
main_page.enter_field(@@test.data[:text])

```

end

end

class Test\_Data  
attr\_accessor :data  
def initialize

```
  username = ['user', 'invalid_name']
  password = ['pswd', 'invalid_password']
  text = ['something', 'else']

  @data= {
    :url => 'http://whatever',
    :username => username[@@i],
    :password => password[@@i]
    :text => text[@@i]
    }

   @@i += 1 unless username.length #need to work this out
end

```

end

Ideally I want to run the class TC until an array length is reached in  
the Test\_Data class.
