Sample Program for junit-3.8.1.jar
How to write a Sample program to use junit-3.8.1.jar?
✍: FYIcenter.com
JUnit is a simple framework to write repeatable tests for Java applications.
In order to use junit-3.8.1.jar,
we need to write a simple Java application, Calculator.java:
// Copyright (c) 2015 FYIcenter.com public class Calculator { public int evaluate(String expression) { int sum = 0; for (String summand: expression.split("\+")) sum += Float.valueOf(summand); return sum; } }
This sample Java program is simple. But it does have some issues:
Let's write JUnit test program, CalculatorTest.jar, to show those issues:
// Copyright (c) 2015 FYIcenter.com import junit.framework.TestCase; public class CalculatorTest extends TestCase { public void testAddition() { Calculator calculator = new Calculator(); int sum = calculator.evaluate("1+2+3"); assertEquals(6, sum); } public void testFraction() { Calculator calculator = new Calculator(); int sum = calculator.evaluate("2.4+2.6"); assertEquals(5, sum); } public void testSubtraction() { Calculator calculator = new Calculator(); int sum = calculator.evaluate("10-1"); assertEquals(9, sum); } }
This JUnit test program does the following:
Of course, you need to compile them with JDK to make them ready to run:
\fyicenter>java -version java version "1.8.0_45" \fyicenter>javac Calculator.java \fyicenter>javac -cp .;\local\lib\junit-3.8.1.jar CalculatorTest.java
Note that you need to provided junit-3.8.1.jar in the classpath to compile CalculatorTest.java.
