It is considered to be the mostvulnerableand sensitive part. Unit testing is the first level of testing where you check if an individual unit/component of software performs as designed. Moreover, it shouldnt spin up a thread or call out to collaborators. To perform unit tests, your code must be modular. To make the testing process more effective, you should have well-designed documentation, which clearly defines the interactions between each unit. Beta Testing happens in the customers environment. If writing unit tests causes difficulties for a developer, it means that the code is poorly designed. From unit testing to acceptance tests, the testers need to guarantee that all segments of the product are tested completely, with no obstacle. Functionality Testing - Also known as functional completeness testing.
