The document serves as an introductory guide to Java test automation, specifically using JUnit and TestNG frameworks. It covers setting up a test project, writing tests, and includes best practices such as naming conventions and assertions. Additionally, it provides practical exercises and coding examples, along with instructions on generating HTML reports and configuring dependencies via Maven.

3. What are we going to learn
● Setting up a test project from scratch
● How to write a test using JUnit
● How to write a test using TestNG

4. Good habits
● Consistent naming convensions of tests
● Atomic
● Single assertion

5. Common terminology
● Test suite
● Test class
● Test
● Before and After test hooks
○ class
○ test
● Assertions

6. Tools you need
● Git
● Maven
● Java IDE (Eclipse or IntelliJ)

7. What to test against
● The world famous calculator program
● Get the code from Github
○ git clone git@github.com:limsim/intro-
to-java-test-frameworks-start.git

8. Different ways of running test
● From command line run mvn test
● Use IDE
● (You could use Java and JUnit but the
command is long and not user friendly)

9. Test class
public class CalculatorTest
{
}

10. Test
public class CalculatorTest
{
@Test
public void addReturnsSumOfTwoNumbers()
{
}
}

11. Test
Add JUnit dependency to Maven
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
</dependencies>

12. Make an assertion
public class CalculatorTest
{
@Test
public void addReturnsSumOfTwoNumbers()
{
Assert.assertEquals("Fail!", 1,
new Calculator().add(1, 1));
}
}

13. Common assertions
● assertTrue
● assertFalse
● assertNotNull
● assertSame
● assertNotSame

14. Excercise
Try writing tests to do the following
● Use assertTrue to check that expected and actual results
from add() are the same.
● Use assertFalse to check that expected and actual results
from add() are not the same.
● Use assertNotNull to check that Calculator has been
created.

15. Generate HTML reports
Need to add a reporting plugin
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-report-plugin</artifactId>
<version>2.18.1</version>
</plugin>
</plugins>
</reporting>

16. Generate HTML Report
● Run mvn site
● The HTML Report is generated in target/site

17. Test hooks
@Before
public void doThisFirst() {
}
@After
public void doThisLast() {
}

18. TestNG
Add TestNG dependency
<dependencies>
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.8.8</version>
<scope>test</scope>
</dependency>
</dependencies>

19. TestNG
● Create a test class
● Create a test method
● Write an assertion

20. TestNG hooks
@BeforeClass
public void createCalculator() {
}

21. TestNG hooks
● AfterClass
● Before(After)Method
● Before(After)Suite
● Before(After)Groups
● Before(After)Test
