Assert that a block of code is throwing

[danieldietrich]

Hi,

it would be great to see integration with Java 8. This enables lazy evaluation, which would be helpful to assert that specific exceptions are thrown, e.g.

Assertions.assertThat(() -> {
            throw new RuntimeException("Error");
        }).isThrowing(RuntimeException.class, "Error");

For a working example implementation please take a look at this gist.

Thanks,

Daniel

you can give a try to AssertJ 3.0 that provides a similar feature : http://joel-costigliola.github.io/assertj/assertj-core-news.html#assertj-core-3.0.0-thrown-by
