Unit Testing With XCTest

This IOS app demonstrates unit tests and user interface tests using Xcode's built-in testing framework.

We are going to answer the questions like these by unit testing:

• Are the words loaded correctly?
• Are the word counts correct?
• Did the words get counted in an appropriate time?
• Does our user filtering work?
• When the view controller loads, does it show the correct number of words?

• Use Cmd+U to apply all unit tests

Future works

• Can you write a test that verifies there are 55 table rows when the user filters by words that appear 1000 or more times?
• Can you write a test that ensures something sensible happens if the cancel button is pressed?
• Can you write a performance test to ensure applyUserFilter() doesn't get any slower?
• How can you solve the empty string issue when entered in the textfield?

Main Targets

Unit Testing, User interface testing, XCTest, filter, NSCountedSet, private setters
