In this assignment, you will design a function to calculate the slope of a line connecting two points in the Cartesian plane. Once the function is designed, you will be tasked with creating appropriate test cases to ensure its robustness. Step 1: Function Implementation (30% of grade) Design a function named calculateSlope that accepts the cartesian coordinates of two points as its parameters. The function should return the slope of the line connecting these two points. Step 2: Design Test Cases (70% of grade) Create unit test cases for the calculateSlope function. Your test cases should address: Typical scenarios of points in different quadrants. Any other edge cases you deem necessary. Deliverables: Submit a document that includes: Your function implementation in Python, Java, C, or pseudo code. Ensure your code or pseudo code is well documented. All your test cases, presented systematically, alongside their expected output. Include a rationale for each test case, explaining why it was chosen. During testing using your test cases, if you encounter any bugs, detail them in the document, specifying how you addressed them. Clearly list and explain any assumptions you made regarding the function's behavior or input conditions.
