Test expected exceptions in Kotlin

Question

In Java, the programmer can specify expected exceptions for JUnit test cases like this:

@Test(expected = ArithmeticException.class)
public void omg()
{
    int bl         


        

Answer 1

Kotlin has its own test helper package that can help to do this kind of unittest.

Your test can be very expressive by use assertFailWith:

@Test
fun test_arithmethic() {
    assertFailsWith {
        omg()
    }
}
