I'm not sure what your question is.  The hint you give above pretty much 
tells you what to do.  The basic issue here is that you started out with 
a list (well, tuple) of filenames.  You can use os.listdir() to get a 
list of filenames that exist in the current directory.  The problem is 
that you can't compare these two lists directly, because lists are 
ordered.  Converting both lists to sets eliminates the ordering and lets 
you compare them.

I think you want to end up with something like:

    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 = os.listdir()
        self.assertEqual(set(dir_names), set(filenames))

The above code isn't tested, but it should give you the gist of what you 
need to do.
