2. Writing Tests

The following example provides a glimpse at the minimum requirements for writing a test in JUnit Jupiter. Subsequent sections of this chapter will provide further details on all available features.

A first test case

import static org.junit.jupiter.api.Assertions.assertEquals;
import example.util.Calculator;
import org.junit.jupiter.api.Test;
class MyFirstJUnitJupiterTests {
    private final Calculator calculator = new Calculator();
    @Test
    void addition() {
        assertEquals(2, calculator.add(1, 1));
    }
}
