Hi!

I just made an update to my fluent assert library. This is a library that allows you to write asserts in a BDD style.

Right now, it contains only asserts that I needed in my projects and I promise that I will add more in the future.

I would really appreciate any feedback that you can give me.

Thanks!

This looks awesome. Why haven't I seen that before. Can it be used with unit-threaded?

I did not tested it with unit-threaded, but when an assert fails it throws an exception so it should work with any test runner

I got really confused looking at the examples until I realized that should returns a struct.

You might add an approxEqual for ShouldNumeric. If you have floating point numbers, it's usually more helpful than equal is.

It'll work, but it won't end up reporting it the same way. If you'd like that to work seamlessly it's a question of having `version(Have_unit_threaded)` (or however it is it's spelled) that imports and throws `unit_threaded.should.UnitTestException`. Then Bob's your uncle.

Ok, I see, thanks. On the other hand I just remembered that unit-threaded already have a very similar API for the assertions.

I was looking for testing exceptions. It is not documented, but the seems to be there. Still, it looks weird, because it does not fit the style:

    should.not.throwAnyException({
      throw new Exception("test");
    });

what do you mean, they are not documented? there is a md file fith some examples here: https://github.com/gedaiu/fluent-asserts/blob/v0.3.0/api/exceptions.md

What do you think I can do to have the exception asserts to fit the style?

The expression comes first in the other use cases. The following is not very pretty but seems to work with my proof of concept below:

    ({
        throw new Exception("test");
    }()).should.not.throwAnyException();

I checked the syntax with the following code:

struct Should {
    Should not() {
        return this;
    }

    Should throwAnyException() {
        return this;
    }
}

Should should(E)(lazy E expr) {
    return Should();
}

void main() {
    ({
        throw new Exception("test");
    }()).should.not.throwAnyException();
}
