[Piuparts-devel] Tests for piupartslib.dwke

[Herbert Fortes]

Hi,

I created tests/test_dwke.py for piupartslib.dwke. Two of them 
maybe not really necessary. But helped me to get started.

To test make_kprs function I split it into more four functions. 
Simplify tests. Skips read/write a file.

Then I noted the IOError can happen because of two open() with 
two different paths. But only one path is used to compose the log
message. The paths differ because of a 'replace_ext()'. I created
'read file' and 'write file' functions. Each one uses its own path
for logging. 

Please check if the patch[0] worth apply. (5 commits patch)

Add tests/test_dwke.py
Create kprs_string function
Create read_logpath function
Create write_kprs function
Create build_kprs function
