Hello need help for this assignment I am new to unit test cases. And pls showcase the unit test cases that will work pls. Thank you

Writing Test Cases Using JUnit
Learning objectives:
Create unit tests and fix defects. Use JUnit for unit-level testing to confirm defects are fixed.
Writing report for your work:
=>Format:
i. Screenshot of code after being fixed.
ii. Screenshot of same unit test passing.

Answer 1

The question focuses on writing unit test cases using JUnit to verify code functionality and assess case study report quality. Screenshots of corrected code and passing tests confirm the improvements.

Step-by-step explanation:

Writing Test Cases Using JUnit

The objective of learning to write unit test cases with JUnit is to create tests that verify the functionality of a specific part of your code. When a defect is identified, these tests help ensure that once you fix the issue, you will not reencounter the same problem. To evaluate the effectiveness and quality of a case study report, it is essential to revise the writing to comply with the genre conventions and assess how well the report demonstrates the resolution of identified defects. Screenshots of the code after being fixed and of the passing unit tests provide evidence that the iterations of development and testing lead to improvements in the codebase.

When writing unit test cases using JUnit, it is important to ensure that you cover all possible scenarios and test the functionality of each unit of code.

Here is an example of a unit test case:

Create an instance of the class you want to test.

Call the method you want to test and store the result.

Use assertions to validate the result.

For example, if you have a method that calculates the square of a number, you can write a unit test case to verify its correctness:

public void testSquare() {

 int result = MathUtils.square(5);

 assertEquals(25, result);

}
