Importance of the test cases for the KnitLib

Having test cases is very important especially for a library like KnitLib because using test cases; we can clearly test particular fields.  In KnitLib, test cases show the information of how the KnitLib should be checked. Also test cases help for new contributors to understand about the KnitLib.

There are several test cases for the current KnitLib implementation such as tests on ayab communication, tests on ayab image, tests on command line interface, tests on KnitPat module and tests on knitting plugin.

For an example in ayab communication there are several important functions have been tested. Test on closing serial port communication, test on opening serial port with a baud rate of 115200 which ayab fits, tests on sending start message to the controller, tests on sending line of data via serial port and tests on reading line from serial communication.  Most of these tests have been done using mock tests. Mock is a python library to test in python.  Using mocks we can replace parts of our system with mock objects and have assertions about how they have been used. We can easily represent some complex objects without having to manually set up stubs as mock objects during a test.

It is very important to improve further test cases on the KnitLib because with the help of good test cases we can guarantee that the KnitLib’s features and functionalities should be working great.
