Quick – The Swift (and Objective-C) testing framework

Quick is a behavior-driven development framework for Swift and Objective-C. Inspired by RSpecSpecta, and Ginkgo.

Quick example

// Swift

import Quick
import Nimble

class TableOfContentsSpec: QuickSpec {
  override func spec() {
    describe("the 'Documentation' directory") {
      it("has everything you need to get started") {
        let sections = Directory("Documentation").sections
        expect(sections).to(contain("Organized Tests with Quick Examples and Example Groups"))
        expect(sections).to(contain("Installing Quick"))

      context("if it doesn't have what you're looking for") {
        it("needs to be updated") {
          let you = You(awesome: true)


Quick comes together with Nimble — a matcher framework for your tests. You can learn why XCTAssert() statements make your expectations unclear and how to fix that using Nimble assertions here.
