Q231950 Rorschach Versions Save

This release refines the public API.

• makes the expect function part of an extension on XCTest
• adds documentation
• refactors production and test code
• compiles on Xcode 14 Beta 1 and Beta 2
• compiles with swift-tools-version:5.7

Subclassing of Steps and Assertions is no longer necessary and the obligatory Context has been removed.

Thanks to @devandanger for adding Xcode 12 support! That's also the only change in this release to mention in the log.

Rorschach is a Swift Package for writing Xcode UI Tests in a BDD style. This first version allows to expect given/when/then acceptance criteria in a context defined by the test.

let context = UniverseContext()

expect(in: context) {
    Given {
        ILearnABitMore()
        IBuildARocket()
    }
    When {
        ILaunchARocket()
    }
    Then {
        ICanSeeTheStars()
    }
}
