## Testing
After any change to the detection routines or match tables, it's always
a good idea to run `make test`. If some test fails, and you're confident
that the test is wrong and needs fixing, run `make fix-tests`.
You can also add a new test (which is basically a file containing
the raw CPUID data and the expected decoded items) by using
`tests/create_test.py`. The workflow there is as follows:
1. Run "cpuid_tool" with no arguments. It will tell you that it
has written a pair of files, raw.txt and report.txt. Ensure
that report.txt contains meaningful data.
2. Run "tests/create_test.py raw.txt report.txt > «my-cpu».test"
3. Use a proper descriptive name for the test (look into tests/amd
and tests/intel to get an idea) and copy your test file to an
appropriate place within the tests directory hierarchy.
AIDA64 CPUID dumps (mostly found on [InstLatx64](http://instlatx64.atw.hu/)) are also supported.
To create a new test based on a AIDA64 CPUID dump, you can do:
```shell
cpuid_tool --load=aida64_raw.txt --outfile=report.txt --report
./tests/create_test.py aida64_raw.txt report.txt > tests/xxx/yyy/my-cpu.test
```
For non-developers, who still want to contribute tests for the project,
use [this page](http://libcpuid.sourceforge.net/bugreport.php) to report
misdetections or new CPUs that libcpuid doesn't handle well yet.
