In this tutorial we will dive into JUnit5 framework even more basing on simple Calculator project that will grow with us during tutorial.
Project Structure:
.
├── pom.xml
└── src
├── main
│ └── java
│ └── Calculator.java
└── test
└── java
└── CalculatorTest.java
Our Calculator.java look like this:
public class Calculator {
static Double divide(Double a, Double b) {
if (b != 0) {
return a / b;
}
else{
throw new ArithmeticException("Division by 0 is impossible!");
}
}
public static void main(String[] args) {
System.out.printf(Calculator.divide(8.0,2.0).toString());
}
}
