Re: Unittest - testing for filenames and filesize

Show all headers | View raw

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
