Java JUnit Library. Types of Testing

1. Testing in Development

Let's talk about types of testing and which testing methods developers use. You will learn about the stages an application goes through before being delivered to the client and the specific tests you will need to write.

What is Testing, and Why do We Need It

Types of Testing

2. Unit Tests

In this section, we're going to dive into unit testing — you'll get the rundown on its structure in Java and the ins and outs of crafting them the right way. Setting up your IDE, importing necessary libraries, and lots of hands-on practice.

Set-Up

Test-Driven Development

Creating Unit Tests

@BeforeEach

How to Test `void` Methods

Assertions

Assertions Practice

Section 2 Summary

3. Exceptions

In this section, we will enhance our coding skills by dealing with errors that can also be caught in unit tests. When testing an application, you may come across various errors, and sometimes they should be turned into exceptions. I will explain how to catch exceptions in your code, test them, and handle them properly.

Section 2 Summary

Congratulations on completing the second section of this course!

In this section, you learned how to import necessary libraries for writing unit tests and how to test your code using unit testing.

You tested individual modules and also learned about various assertions that will allow you to easily test any of your code. Additionally, you discovered the Test-Driven Development (TDD) approach to programming, and who knows, maybe you've already decided to start programming using this approach.

In any case, you've done great work! With tests, your code will look much better and more professional.

1. What is the primary purpose of unit testing?

3. What is a characteristic of a good unit test?

4. Which of the following is true about Test-Driven Development (TDD)?

5. In JUnit, how are assertions used in a test method?

6. In JUnit, what is the purpose of the `@BeforeEach` annotation?

7. What is the RED-GREEN-REFACTOR cycle in TDD?

What is the primary purpose of unit testing?

Selecione a resposta correta

To validate that individual units of software work as intended.

To check the compatibility of the software with different operating systems.

To test the performance of the entire application.

In JUnit, what annotation is used to indicate a method is a test method?

Selecione a resposta correta

@Test

@TestMethod

@TestCase

What is a characteristic of a good unit test?

Selecione a resposta correta

It depends on other tests for data.

It tests multiple functionalities at once.

It is isolated and tests only one functionality.

Which of the following is true about Test-Driven Development (TDD)?

Selecione a resposta correta

Writing tests after writing the code

Writing tests before writing the code

Writing tests and code simultaneously

In JUnit, how are assertions used in a test method?

Selecione a resposta correta

To compare the expected output with the actual result

To check the speed of the code execution

To debug the application code

In JUnit, what is the purpose of the @BeforeEach annotation?

Selecione a resposta correta

To run a method before each test in a test class

To initialize test data after each test method

To declare a method that cleans up after all tests

What is the RED-GREEN-REFACTOR cycle in TDD?

Selecione a resposta correta

Write a failing test, make it pass, and then improve the code

Write a passing test, make it fail, and then refactor

Refactor the code, write a test, and make it pass

Tudo estava claro?
