Integration test is missing.

There is actually no test that proves if the otf2-merger produces the expected trace on the target system for a small set of input traces (like 2).

What you could do:
Option A:

• require OTF2 Python bindings
• Add a python script to your tests that produce two traces with defined content
• Run the merger
• Add another script that checks the traces and the expected content

Option B:

• require Score-P
• add a small C code to your test that produces small traces with defined content
• Run the merger
• Add shell script that checks the traces and the expected content using otf2-print
