def test_removeNameElement_in_end_of_filename(self):
'''
**Purpose:**
Uses the ```removeNameElement``` function to remove part of the file
name that is at the end of the filename
```an_even_longer_file_name.txt``` The test removes ```xt``` from the
filename.
*Test Confirmation*
The following assertions are performed:
Performs an ```assertEqual``` on the result of the call to
```removeNameElement``` with the expected result:
```expected = self.dirname + os.sep + "an_even_longer_file_name.t"```
```self.assertEqual(expected,result,"Element removal not done
correctly")```
Performs an ```assertEqual``` on the path to ensure the file exists on
the file system with the correct file name:
```self.assertEqual(os.path.exists(expected) == 1, True,
"File not renamed correctly")```
