SequenceTypeTests.swift
TLDR
The file SequenceTypeTests.swift contains a set of test cases for working with sequence types in the SwiftyJSON library. The tests include operations on JSON arrays and dictionaries, including different types of elements such as numbers, booleans, strings, and null values.
Methods
testJSONFile
This method tests the parsing of a JSON file using the SwiftyJSON library. It checks for specific values in the parsed JSON data.
testArrayAllNumber
This method tests operations on a JSON array containing all numbers. It checks the count of the array and asserts the values and indexes of the array elements.
testArrayAllBool
This method tests operations on a JSON array containing all booleans. It checks the count of the array and asserts the values and indexes of the array elements.
testArrayAllString
This method tests operations on a JSON array containing all strings. It checks the count of the array and asserts the values and indexes of the array elements.
testArrayWithNull
This method tests operations on a JSON array containing null values. It checks the count of the array and asserts the values and indexes of the array elements.
testArrayAllDictionary
This method tests operations on a JSON array containing dictionaries. It checks the count of the array and asserts the values and indexes of the array elements.
testDictionaryAllNumber
This method tests operations on a JSON dictionary containing all numbers. It checks the count of the dictionary and asserts the values and keys of the dictionary elements.
testDictionaryAllBool
This method tests operations on a JSON dictionary containing all booleans. It checks the count of the dictionary and asserts the values and keys of the dictionary elements.
testDictionaryAllString
This method tests operations on a JSON dictionary containing all strings. It checks the count of the dictionary and asserts the values and keys of the dictionary elements.
testDictionaryWithNull
This method tests operations on a JSON dictionary containing null values. It checks the count of the dictionary and asserts the values and keys of the dictionary elements.
testDictionaryAllArray
This method tests operations on a JSON dictionary containing arrays. It checks the count of the dictionary and asserts the values and keys of the dictionary elements.
testDictionaryIteratingPerformance
This method tests the performance of iterating over a large JSON dictionary. It creates a JSON dictionary with 1000 elements and measures the time it takes to iterate over the dictionary.
