There is the need to add more test case to test tinfoil, a reference of current errors and implementation needs to be addressed.
Anibal are you able to give more detailed information about, what errors are found and what kind of test are needed.
The current tinfoil module is at [1] the test cases needs to cover the current functionality for initialize/parse the meta data using tinfoil. Also tinfoil needs to be extended to provide another useful methods like load recipes, etc. [1] http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/bitbake/lib/bb/tinfoil.py
I created a Draft of the Test Plan, below is the link https://wiki.yoctoproject.org/wiki/Tinfoil_Test_Plan
Test Plan and basic test cases are now documented, bug 10940 was created to increase the coverage on the tests.
the test plan for tinfoil verification was created https://wiki.yoctoproject.org/wiki/Tinfoil_Test_Plan
