XSmallTest

Introduction

XSmallTest (XSM) is a minimal single-header implementation of a test DSL that generates test cases compatible with Xcode's XCTest.

Usage

Simply include XSmallTest.h, declare your test case with xsm_given, and write test sections with arbitrarily nested xsm_when and xsm_then statements:

#import "XSmallTest.h"

xsm_given("an integer value") {
    int v;
    xsm_when("the value is 42") {
        v = 42;

        xsm_then("the value is the answer to the life, the universe, and everything") {
            XCTAssertEqual(42, v);
        }
    }
}

Set-up and tear-down can be performed inline, based on standard C/Objective-C nesting rules; XSM conditionalizes execution of the test blocks automatically based on nesting.

Standard XCTest assertions are supported, as are Xcode 6's asynchronous testing APIs. Within the context of a test section, self refers to a valid XCTestCase instance.

TODO

• Performance testing (Xcode 6). This will likely require exposing a new clause (measure()) that generates XCTest selectors ending with 'Performance'.
