If you have seen any of the news lately, it is not hard to imagine why software bugs cost the economy billions of dollars per year as well as costing lives. The ability to test your code (and other’s code) is probably one of the most important skills to know as a developer. Knowing how to track down and fix bugs is also critical. Testing can mean adding print statements to output data at certain points in a program to visually check it. Testing can also involve developing separate programs to test the functionality of the code itself. In this course, you will create a Python application that implements a new sorting algorithm. You will also create a test to sort the algorithm, and use debugging to find bugs in the code. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
