Re: Unittest - testing for filenames and filesize

Thanks Rob,

I'v modified the test_3 like this:


    def test_3(self):
        f = open("test.dat", "wb")
        filesize = (b'b'*1000000)
        f.write(filesize)
        f.close()
        statinfo = os.stat("test.dat")
        self.assertEqual(statinfo.st_size, filesize)
    
I'm still getting AssertionError and the error says: 1000000 !=b'

Help appreciated.
