LiteralConvertibleTests.swift

TLDR

This file contains the unit tests for the LiteralConvertible class in the SwiftyJSON library. The tests cover the conversion of different types of literals (numbers, booleans, strings, arrays, and dictionaries) to JSON objects.

Methods

testNumber

This method tests the conversion of a number literal to a JSON object. It asserts that the resulting JSON object has the expected integer and double values.

testBool

This method tests the conversion of a boolean literal to a JSON object. It asserts that the resulting JSON object has the expected boolean value.

testString

This method tests the conversion of a string literal to a JSON object. It asserts that the resulting JSON object has the expected string value.

testNil

This method tests the conversion of a nil literal to a JSON object. It asserts that the resulting JSON object is indeed null and not any other value.

testArray

This method tests the conversion of an array literal to a JSON object. It asserts that the resulting JSON object has the expected array value.

testDictionary

This method tests the conversion of a dictionary literal to a JSON object. It asserts that the resulting JSON object has the expected dictionary value.
