Solving problems with functions unit test

A unit test is a way to verify the correctness of a function by testing it against different inputs and expected outputs. To test a function, you create test cases that encompass a range of scenarios the function could encounter.
Here is an example of how to conduct a unit test for a function that solves a problem:
1. Define the function you want to test. For example, let's say you have a function called `addOne` that takes an input number and adds 1 to it.
```python
def addOne(num):
return num + 1
```
2. Create test cases for the function. Consider various scenarios, including typical inputs, edge cases, and invalid inputs.
```python
def test_addOne():
assert addOne(0) == 1
assert addOne(5) == 6
assert addOne(-1) == 0
assert addOne(100) == 101
```
3. Run the test cases using a testing framework such as `pytest` or the built-in `unittest` module in Python.
4. Analyze the test results to check if the function behaves as expected. If all test cases pass, then the function is performing correctly. If any test cases fail, you need to investigate and fix the issues in your function.
By conducting unit tests, you can verify the correctness of your functions and catch any bugs or errors early on in the development process. This helps ensure the reliability and stability of your code.
