I'm doing a project at the Federal Institute of Triangulo Mineiro, about a student control system made in php, so I'm starting a test phase using PHPUnit and I have my doubts because I'm not experienced with this tool. I'm not able to install and configure the composer to run these tests, would anyone give me any tips? The System is in github. follow the > link
Note: I already installed and configured PHPUnit the problem is only in this part of the composer.
If someone has a tip that facilitates this installation and configuration I thank you right away.
