A simple tool for combinatorial test cases and JUnit5 code generation.
Install clang through your package manager (most systems), Xcode (OS/X), or from the LLVM website. On Linux, you also need to install recent libstdc++ offered by gcc 5 and c++2a offered by g++-9.
Run make to build the WShabtiPict binary.
Install cygwin and clone this repo into your home folder. Run make to build the WShabtiPict binary.
OR
Use WSL (Windows Subsystem for Linux) (link here) to execute in linux environment without installing cygwin. To compile you need to install build-essential and make
sudo apt update
sudo apt install build-essential
sudo apt install make
sudo apt upgrade
If you are using Ubuntu 18.4 or older you need to install g++-9
./WShabtiPict

#Do you want specify Exclusive Constraints? (y/n)
Please specify your choice: y
To specify a combination to exclude, use the syntax "value1,value2,...".
Use "*" if you don't care about a parameter.
Please specify a combination to exclude or "stop" to terminate: 1,3
