What are unittests in Python?

Posted by Jennifer | Updated on
  • unittest is a unit testing framework of Python.
  • Unit testing means testing different components of software separately. Can you think why unit testing is important? Imagine a scenario, you are building software which uses three components namely A, B, and C. Now, suppose your software breaks at a point time. How will you find which component was responsible for breaking the software? Maybe it was component A that failed, which in turn failed component B, and this actually failed the software. There can be many such combinations.
  • This is why it is necessary to test each and every component properly so that we know which component might be highly responsible for the failure of the software.
