Data-driven unit testing is a concept known to provide great insight into code behavior, due to it being able to execute tests with different sets of data. The insight gained through data-driven unit testing can assist in making informed decisions about application development approaches and can identify potential areas that need improvement. Strategies can be formulated from reports and code coverage available from data unit tests, which can later be used to refactor code with potential performance issues and bugs in the application logic.
Some of the benefits of data-driven unit testing are explained in the following sections.
