Hello,

I am Punit Singh, and I have been working on Chutney for the past one
week. I have already expressed my interest [1] in participating in
GSOC this year for the project - Improving test coverage in tor.

I have made some changes to the code base of Chutney, including
completing some TODO tasks. The code can be found here. [2]

I am currently in the process of completing the proposal for the project.

Here are the things I have done -

1. I am now able to understand the code base of Chutney.
2. I have read parts of the Tor specification [3], not the complete
document.
3. I have computed the test coverage of tor, and have seen that some
parts of the code are totally untested. [4]
4. I know about unit tests and integration tests, how to write them,
how to write testable code, and so on.

I wanted some pointers as to how should I choose which function to
write unit test for (with reference to the application requirement),
and how should I go about writing the unit test (I know that I have to
script individual clients using Stem, I just needed some guidance how
to execute individual functions in the C code from Stem).

I am really interested as well as enthusiastic to work on this. I just
need a little guidance.

Please correct me if I am thinking in the wrong direction.

Thanks,
Punit
