import org.junit.jupiter.api.Test
import org.junit.jupiter.api.DisplayName
import org.junit.jupiter.api.Nested

@DisplayName("Testing Adder")
class AdderTests {
  @Test
  @DisplayName("Adder.add(1, 1) returns 2")
  void "1 + 1 = 2"() {
    assertEquals(2, Adder.add(1, 1), "1 + 1 should equal 2")
  }

  @Nested
  @DisplayName("Negative Integers")
  class Negatives {
    @Test
    @DisplayName("Adder.add(-1, -1) returns -2")
    void "-1 + -1 = -2"() {
      assertEquals(-2, Adder.add(-1, -1), "-1 + -1 should equal -2")
    }
