How about slicing it like this:

 >>> if fileName[-9:-5].lower() == "test":
...     print "there it is"
...
there it is

Alternatively, you could use a regular expression

 >>> x = "blahblahtest.java"
 >>> import re
 >>> reFilename = re.compile(".+test.java", re.I)
 >>> if reFilename.search(x):
...     print "there it is"
...
there it is
