in my experience this is usually achieved by creating a temporary file copying the contents of the current file in and making the modifications as you copy. then deleting the original and renaming the temp file.
So, in your case you'd copy "this is a test" from a.txt to tmp.txt and then insert your "aaaaaa" in tmp.txt . Copy the rest of a.txt into tmp.txt, then delete a.txt and rename tmp.txt to a.txt.
