Deployment is the last stage in the application development process and before that, any application undergoes a comprehensive testing process to validate that the system meets its functional and non-functional requirements. An application comprises several functions, classes, procedures which are referred to a unit. The objective in unit testing is to isolate each unit of the system and validate its precision by identifying and fixing the defects and bugs and benefit of unit testing is that issues can be identified on earlier stages. Chapel currently lacks unit testing, which harms the development of the platform and makes easier to reintroduce past bugs while developing. This project is a proposal to add a set of unit test classes to Chapel.
