Question

I have a requirement to drop my test results into a csv for reporting. In my python test code when I don’t have a value, my variables are filled in the python way with None.

I have been asked to replace these with “Null” in the CSV for the reporting tool. I am thinking this is easy and has probably be solved a hundred times.

Here is the code I came up with:

   for field in (TestCase.productUnderTest,TestCase.versionUnderTest,TestCase.name,TestCase.results,TestCase.lastTestEnd,TestCase.parent,TestCase.level):
        if field == None: 
             field = 'Null'

    ME.csvoutput.write("%s,%s,%s,%s,%s,%s,%s\n" % (TestCase.productUnderTest,TestCase.versionUnderTest,TestCase.name,TestCase.results,TestCase.lastTestEnd,TestCase.parent,TestCase.level))

Unfortunately that only changes the field within the scope of the for loop. How can I change it for the scope of the write statement.

(I would be quite happy to just write “Null” and leave my variables unchanged, but I can work either way.)

Answer 1

result = [TestCase.productUnderTest,TestCase.versionUnderTest,TestCase.name,TestCase.results,TestCase.lastTestEnd,TestCase.parent,TestCase.level]
result = map(lambda x:x==None and 'Null' or str(x), result)
ME.csvoutput.write(",".join(result)+'\n')
