Unit Testing- PHPUnit Every developer understands how inconvenient bugs can be, especially during the production stage when hours of effort are required. Despite the development team's best efforts to eliminate problems during the development process, bugs continue to leak into the code. So, what can be done to remedy these flaws while also removing the tedious work of manual testing? One option is to use Unit Testing, Unit testing is used to test individual units of an application during the coding stage of a software development project. Its purpose is to ensure that each unit of software code operates as expected. In object-oriented languages, a unit is a class or class method, while in procedural and functional software languages, it is a process or function. Unit tests must run rapidly, thus they are performed in isolation from other processes or systems. PHPUnit is a framework independent library for unit testing PHP. Unit testing is a method by which small units of code are tested against expected results. Installing PHPUnit on Ubuntu 1.
