Throws Exception Testing

Additional Verification

You can capture the exception returned by shouldThrow or shouldThrowExactly and perform additional assertions on it.

    val exception = shouldThrow<IllegalArgumentException> {
        throw IllegalArgumentException("Invalid argument")
    }
    exception.message shouldBe "Invalid argument"

Summary

• Use shouldThrow for checking a type or its subclass.
• Use shouldThrowExactly for strict type matching.
• Capture the thrown exception to validate its properties like the message or custom fields.
