Try these first

1. 1.

   What is unit testing?

   Hint

   It verifies the smallest functional parts of your code.

2. 2.

   Give an example of black-box testing.

   Hint

   Focus on inputs and outputs.

3. 3.

   What is the primary purpose of unit testing?

   • To verify individual components
   • To conduct system-wide testing
   • To integrate different software parts

   Hint

   Consider what 'unit' refers to in programming.

4. 4.

   True or False: Unit testing guarantees that the entire application is free of bugs.

   • True
   • False

   Hint

   Think about what unit testing actually covers.

5. 5.

   Create a comprehensive unit test for a given function that computes the factorial of a number, considering edge cases like zero and negative numbers.

   Hint

   Factorials have specific mathematical properties; recall them.

6. 6.

   Discuss the impacts of neglecting unit testing in a software project over time.

   Hint

   Consider how problems can compound in development without checks.
