This document provides an overview of unit testing in Java using JUnit and NetBeans. It discusses what unit testing is, why it is important, and how to get started with simple unit testing in Java projects using JUnit and the testing functionality built into NetBeans. Key steps include creating a test class, writing test cases that use JUnit assertion methods, and running tests from within NetBeans.
Simple Unit Testing With Netbeans 6.1
- 1. Simple Java Unit Testing with JUnit 4 and Netbeans 6.1 Kiki Ahmadi JUG-Bonek
- 2. What is Unit Testing Method of testing that verifies the individual units of the code is working properly (Wikipedia). Test the smallest unit in source code
- 3. Why Unit Testing Verifies if the unit is working offcourse! Make sure the unit is working even after late changes in source code (regression test) Provides living documentation of how the units (e.g Method) works.
- 4. Unit Testing in Java 2 most used testing framework in java Junit TestNG This time we used Junit because its embedded in netbeans 6.1.
- 5. What is Junit Is a unit test framework in java Developed by Kent Beck and Erich Gamma Widely used and commonly become standard unit test framework Is part of xUnit family. xUnit is a ported Junit for various language. PHPunit (PHP) Nunit(.NET)
- 6. Simple JUnit Create test class and test case. Use an assert method for ensuring method output assertEquals() assertTrue() assertNotNull() Can be invoked manually by running the test class or automated by using ant script
- 7. Junit in Netbeans 6.1 You don’t need to load the jar into netbeans project. By default the jar is embedded in test libarary folder And also netbeans has test class and test case code generation menu
- 8. Lets Do The Code Lets start with heating up our Netbeans 6.1 and create new java project. Make a simple class having both return valued and void method. Let the return valued method do simple process for example addition or substraction. Just print something in the void method.
- 10. Create Unit Test Choose this menu in netbeans Tools > Create Junit Test Or just simply press Ctrl + Shift + U. A window dialogue will appear, choose suitable options. Or you can leave it as is. Like I usually do . Test case will automatically build inside the test package folder.
- 11. Unit Test Menu
- 12. Unit Test Window
- 14. Unit Testing Assign the variable value for the test case. Remove the fail() method in return valued method test. Run the test class using Shift + F6. See the test result
