quick/spry

A Mac and iOS Playgrounds Unit Testing library based on Nimble.

Spry

Spry is a Swift Playgrounds Unit Testing library based on Nimble.

The best thing about Spry is that the API matches Nimble perfectly. Which means once you've created your code and tests in a Playground, you can copy them directly into your Xcode project without needing to (re)write them again :)

Nimble: The code in this library has been copied directly from the Nimble project. However it is currently a stripped down version.

Download

There are a couple of ways you can download Spry.

Template

You can download a Playground including the latest version of Spry. Consider this a boilerplate template. It includes Spry in the Sources folder of the Playground, so you can simply start writing tests alongside your code in the Playground.

Manual

You can also download or checkout this repo and simply copy the files into your existing Playground manually. Simply copy the entire Spry folder into your Playground's Sources folder. Easy Peasy!

Nimble-esque

Spry is a stripped down (Lite) version of Nimble that includes a subset of Nimble's Matchers.

Note: This is a port of Nimble only, since Quick doesn't really make sense in the context of a Playground.

The following features are NOT supported (since they are a part of Quick):

describe
context
it

The following features are already implemented:

• expect
• to
• beAKindOf

• equal
• haveCount
• match

The following features are not yet implemented:

• toEventually
• async
• matchError
• throwError
• failWithMessage

Usage

Using Spry is as simple as writing an expect case:

func add<T: ExpressibleByIntegerLiteral>(_ x: T, _ y: T) -> T {
    return x + y
}

// Spry test case
expect(add(4, 5)).to(equal(9))

If you're already familiar with Nimble, then you already know how to use Spry.

For full details on how to write your tests with Spry, I suggest reading over the Nimble docs. Keeping in mind that not all features are currently included.
