These tests are for determining the numbers of physical packages, physical cores,
and logical processors from the data returned by /proc/cpuinfo on Linux hosts.
Each text file in this directory is the output of /proc/cpuinfo on various machines.
The names of all test files should be of the form `Apack_Bcore_Clogical.txt`
where `A`, `B`, and `C` are integers or the character `X`. For example,
a single quad-core processor without hyperthreading would correspond to
`1pack_4core_4logical.txt`, while two 6-core processors with hyperthreading
would correspond to `2pack_12core_24logical.txt`, and would be pretty sweet.
Using `A`, `B`, and `C` from above, code processing the text in these files
should produce the following expected values:
| property | value |
| -------------------- |---------|
| # physical packages | `A` |
| # physical cores | `B` |
| # logical processors | `C` |
(Obviously, the processing code should do this with no knowledge of the filenames.)
If any of `A`, `B`, or `C` are the character `X` instead of an integer, then
processing code should not return a value (return `null`, return `nil`,
raise an exception... whatever makes most sense for your agent).
There is a malformed.txt file which is a random file that does not adhere to
any /proc/cpuinfo format. The expected result is `null` for packages, cores and
processors.
