Unit Testing vs. Integration Testing: What’s the Difference?
Back in 2011, a couple of posts from our blog were focusing on the key differences between unit testing and integration testing. We thought now would be a great time to revisit this question, which comes up time and time again. In case you missed the original post, you can check it out — The Difference Between Unit Testing and Integration Testing, and come right back to this post where we’ll break it down as simply as possible. Ready? Great, let’s get started.
Unit Testing Defined
At its core, unit testing is a type of test to check if an individual small piece of code is doing what it is supposed to do. Sounds simple enough, right?
Unit tests are narrow in scope, they should be easy to write and execute, and their effectiveness depends on what the programmer considers to be useful. These minor, individual tests are intended for the use of the programmer and are not directly useful to anybody else. Done right, they can significantly cut down on fixing bugs in the later development stages. https://goo.gl/PDEZ6d #DataIntegration #ML
