Hi,
I'd like to introduce a collection of testcases for ftrace to
avoid regressions.
For a long time, we've tried to stabilize and extend ftrace
tracing infrastructure. This small test framework is a kind of
stabilizing work for ftrace. For the first step, this series
just introduces a few basic testcases. However, it is easy to
add additional tests. I'd like to ask you, ftrace developers,
to add tests for your features to ensure it will not be broken
by future works.
ftracetest is a tiny bash script so that anyone can easily
understand what it does. I think it is better to share and
discuss this tests before growing it.
- Is it enough to support bash script? (of course you can
invoke other commands from the script)
- What's the good naming method of testcases?
- Is any dependency check required?
BTW, I decided to put this under tools/testing/ftrace instead
of tools/testing/selftests/, because all tests requires root
privilege. It will be one of discussion points. Anyway,
it is easy to integrate this to the selftests.
Thank you,
---
