Thanks for reply, here is the script with trucated datafile
The data file is following ,
--- data file--------
getUSStates~~dict~
{AK: Alaska,
AL: Alabama,
AR: Arkansas,
AZ: Arizona,
CA: California,
CO: Colorado,
....
....
WY: Wyoming }
----data file--------
I want to test function:getUSStates that takes input none and outputs a
dict
of us states.the first line shows function
name~input~output_format~expected_output
Now I have following class and loadTestInfoFromFile function for
loading the values for file and assinging the data to self.outputOfFunc
etc
class getUsStates( unittest.TestCase ):
func_name = None
inputToFunc = None
outputOfFunc = None
outputType = None
setup = None
testUsStates = None
testLength = None
def loadTestInfoFromFile(self):
""" read function name, input to function, output format
and output from file"""
rest = file('data.txt').read()
self.func_name , self.inputToFunc,
self.outputType,outputOfFuncRaw = rest.split("~")
if self.outputType == 'dict':
outputOfFuncRaw = outputOfFuncRaw.split(",")
self.outputOfFunc = {}
for i in range(0,len(outputOfFuncRaw)):
li= ( (outputOfFuncRaw[i].strip()).replace('}','')
).split(':')
self.outputOfFunc[li[0]]=li[1]
def buildTestFunctions( self, returnedVals, func_name, inp ):
self.testReturnVal = lambda : self.assertEqual( inp,
returnedVals )
self.testLength = lambda : self.assertEqual(
len(returnedVals) , len(inp) )
def runFunction():
g = getUsStatesTest()
g.loadTestInfoFromFile()
g.buildFunctions(g.returnedVals,g.func_name,g.outputOfFunc)
if __name__ == "__main__":
unittest.main(defaultTest="runFunction")
Now in the buildTestFunctions() I want to setup 2 unittest test
function that do assertEqual
so that I have 2 functions which are dynamically created from file ,
now I want to associate
these function with unittest and run them.
the above runs correctly reads the data and make 2 funcitons
testReturnVal and testLength
but then I want to associate those funcitons to unittest. and run unit
test but that part i dont
know how to do.
in this way I can define 100 functions with inputs and expected outputs
in a data file
and this type of script will generate similar assert functions for all
of them on fly
and run them
thanks for any input or any alternate approach to it
