This method takes two arguments:6package samples.expectnew;7import org.junit.jupiter.api.Test;8import static org.junit.jupiter.api.Assertions.assertEquals;9import static org.junit.jupiter.api.Assertions.assertThrows;10public class ExpectNewDemoTest {11    public void expectNewDemoTest() {12        ExpectNewDemo expectNewDemo = new ExpectNewDemo();13        RuntimeException runtimeException = assertThrows(RuntimeException.class,14                () -> expectNewDemo.throwExceptionAndWrapInRunTimeWhenInvoction());15        assertEquals("Exception thrown", runtimeException.getMessage());16    }17}18We have created a variable of type RuntimeException and assigned the value returned by the assertThrows() method to it. This method takes two arguments:
