The PDF you uploaded contains an assignment focused on adding unit tests to a Java class using JUnit 5. Here's a detailed breakdown of the task and the steps you need to follow:

### Java Assignment: Adding Unit Tests with JUnit 5

**Learning Objectives:**
1. Understand the importance of unit testing.
2. Write unit tests using JUnit 5 annotations.
3. Verify code functionality using assertions.

**Task Steps:**

1. **Review the Provided Java Class:**
   - You'll receive a class with methods for calculations, string manipulation, etc.

2. **Identify Testable Functionalities:**
   - Analyze the class to determine which methods or functionalities require testing.

3. **Create a New Test Class:**
   - In the same package as the original class, create a new class with a name ending in "Test".

4. **Annotate the Test Class:**
   - Use the `@Test` annotation from `org.junit.jupiter.api` to mark the class as a JUnit test class.

5. **Write Test Methods:**
   - Create individual methods for each functionality you want to test.
   - Annotate each method with `@Test`.

6. **Set Up Test Data:**
   - Inside each test method, define the necessary input data for the functionality being tested.

7. **Perform the Test:**
   - Call the method from the original class with the defined input data.

8. **Verify the Results:**
   - Use assertion methods from `org.junit.jupiter.api.Assertions` to compare the actual output with the expected output. Common assertions include `assertEquals`, `assertTrue`, and `assertFalse`.

### Resources for JUnit 5:

- **JUnit 5 User Guide:** [JUnit 5 User Guide](https://junit.org/junit5/docs/current/user-guide/)
- **JUnit 5 by Example:** Java Unit Testing with JUnit and TestNG (URL not provided)
- **JUnit 5 Crash Course (YouTube):** YouTube JUnit 5 Crash Course (URL not provided)

### Tips:

- Focus on testing individual functionalities within a method.
- Consider various scenarios (edge cases) for each test.
- Use meaningful variable and method names for better readability.

### Submission Requirements:

- Submit your original Java class along with the newly created test class.
- Ensure your test class compiles and runs successfully.

### Summary:

The assignment emphasizes the importance of unit testing to ensure code reliability and maintainability. You need to create a test class, annotate it appropriately, write test methods, set up test data, perform tests, and verify results using assertions.

If you have any questions or need further assistance, feel free to ask.

Here are some questions you might consider asking:
1. Can you provide an example of a simple JUnit test class?
2. How do I use assertions in JUnit 5?
3. What are some common edge cases to consider when writing unit tests?
4. Can you explain the importance of unit testing in software development?
5. How do I run JUnit tests in my IDE?

**Tip:** Always test your code with various inputs, including edge cases, to ensure robustness and reliability.
