Thank you guys, Roy and Terry.
I has been great help.
I still need some help. Here is the updated code:
Demostration of setUp and tearDown.
The tests do not actually test anything - this is a demo.
"""
import unittest
import tempfile
import shutil
import glob
import os
class FileTest(unittest.TestCase):
def setUp(self):
self.origdir = os.getcwd()
self.dirname = tempfile.mkdtemp("testdir")
os.chdir(self.dirname)
def test_1(self):
"Verify creation of files is possible"
filenames = {"this.txt", "that.txt", "the_other.txt"}
for filename in filenames:
f = open(filename, "w")
f.write("Some text\n")
f.close()
self.assertTrue(f.closed)
dir_names = set(os.listdir('.'))
self.assertEqual(set(dir_names), set(filenames))
def test_2(self):
"Verify that current directory is empty"
self.assertEqual(glob.glob("*"), [], "Directory not empty")
def test_3(self):
f = open("test.dat", "wb")
filesize = b"0"*1000000
f.write(filesize)
f.close()
self.assertEqual(os.stat, filesize)
def tearDown(self):
os.chdir(self.origdir)
shutil.rmtree(self.dirname
The test_3 is to test if the created binary file har the size of 1 million
bytes. Somehow it is not working. Any suggestions?
Thanks
