Unit Testing vs. Component Testing in Lagom

Let’s first understand the basic difference between unit testing and component testing and then we will have a look at a practical application of unmanaged service in lagom with its test cases. Difference between Unit Testing and Component Testing Unit Testing involves testing of individual units(classes) to demonstrate that the program executes as per the specification and it validates the design and technical quality of Continue Reading
