Hi everybody,  
I have a few classes containing a few tescase methods.  
I would like to create a new class in order to run different tescases  
methods of different classes:

file: testcases/myclass1.rb  
class Myclass1 \< Test::Unit::Testcase  
def setup  
end  
def test01\_example  
end  
def test02\_example  
end  
def test03\_example  
end  
def teardown  
end  
end

file: testcases/myclass2.rb  
class Myclass2 \< Test::Unit::Testcase  
def setup  
end  
def test01\_example  
end  
def test02\_example  
end  
def teardown  
end  
end

file: testsuites/running.rb  
class RunningTestCases \< Test::Unit::Testcase  
def setup  
end  
def test01\_beep

```
require 'testcases/myclass1'
Myclass1.new().test03_example()
Myclass1.new().test01_example()

require 'testcases/myclass2'
Myclass2.new().test01_example()

```

end  
def teardown  
end  
end

This is more or less what I’m trying to do, but it’s not working.

Any idea?

In the example I was inheriting from Test::Unit::Testcase but I’m not  
doing that in the real example, I’m inheriting from a superclass that is  
inheriting from Test::Unit::Testcase, but I think it doesn’t matter.

So any ideas… I’ll really appreciate it.

Thank you.

it’s class Myclass1 \< Test::Unit::TestCase

are you coming from Java-Programming?

you don’t need all the stuff in your running.rb script.

Just create a running.rb file with this content:

require ‘test/unit’  
require ‘myclass1’  
require ‘myclass2’

Calling this script all your tests will be executed.

For further examples you might read some tutorials for organizing test  
in  
test-cases and test-suites.

Another solution could be using the ‘include’ sentence but the result is  
the same, it doesn’t work

it will not help to create only specific test-objects in your script.  
At the end of your script ALL test-definitions which where required are  
executed - this is the way how test-unit works.

So it’s impossible to execute only a few test cases methods of different  
classes in a new class… isn’t it?

Hi Thomas, I knew it.  
What I was trying to do is to run not all the test cases in each file.  
For example only test03\_example() and test01\_example() from MyClass1  
and test01\_example() from MyClass2
