What is MAcroExpressions Test Application (Maestra)?
[Updated!] This is a new updated version. Same rationale, better implementation. Maestra is a reference implementation of a C/C++ unit test environment described in the article “C code unit testing on a shoestring” by Ark Khasin (and also discussed below). It is free for use and modification; however it comes without any warranty whatsoever. The name stands for MAcroExpressions Test Run Application; it is also an Italian term for a (female) elementary school teacher. That seems quite appropriate for a testing environment.
