Unit test, inheritance and changing og parrent variables (?)

[Kga Agk]

Question at the end. ( i dont know exactly what i should write as the
topic)
I want to test some programs that are running on a server.

So I have a general controller class to execute programs on this server

class GeneralController

def initialize
…
some variables to connect to server and application name and so on.
Variable to hold inputs that are going to be plotted in to the given
program when it asks for inputs.
And some variables to hold stdout, stderr so they can later be tested to
seeif they are correct.
…
end

some access methods to some of the variables above

def start_program
…
it start the program from the server
..
end


and to run the program only once for each test case I have made this

class GenTest < Test::Unit::TestCase

It has some variables.
Like a variable that holds a generalController class,
@cenCon = generalController.new
And variables for inputs and the program name
@inut = “â€
@app_name = “â€

class << self
def startup
It sets the input variable and program name in the generalController
class
…
this starts the program in the class above
end

def shutdown

end

def suite
mysuite = super
def mysuite.run(*args)
GenTest.startup()
super
GenTest.shutdown()
end
mysuite
end
end
end



The plan is that for each test it is only needed to change this, at
least for most test. Since I have to write many test I want to write as
little as possible on each test as I can.

class TestX < GenTest

Set inputs in the input variable of the parent class
Set the program name in the parent class
(probably some more here later)

Some test assertions under here
…

end


The problem is that I dont know how to set @input and @app_name in
GenTest from the TestX class. I have tried to make def initialize
method, but that did not work (som eerrors and stuff). The only way I
managed it was to make those variables global, but then they affect all
my tests.

"The only way I

I ment as class (singeltone?) variables @@. It pobably works with global
to.

And when i sed taht the programs i shal test is on a server, i ment that
they are on a server but they are runn (interpreted) tru a different
program that has a ruby interreter (compiler) in it.
