Is there a better way to assert that a method throws an exception in JUnit 5?

Currently, I have to use an @Rule in order to verify that my test throws an exception, but this doesn't work for the cases where I expect multiple methods to throw exceptions in my test.

You can use assertThrows(), which allows you to test multiple exceptions within the same test. With support for lambdas in Java 8, this is the canonical way to test for exceptions in JUnit.

Per the JUnit docs:

import static org.junit.jupiter.api.Assertions.assertThrows;


void exceptionTesting() {

    MyException thrown =


           () -> myObject.doThing(),

           "Expected doThing() to throw, but it didn't");
