This brief step-by-step advisor walks you thru unit checking out, mocking and non-stop integration and the way to get those key parts working on your fast initiatives. This booklet additionally appears to be like at how you can write your fast apps utilizing try pushed improvement (TDD).
Agile practices have made significant inroads in iOS improvement, notwithstanding it’s very strange to determine anything as simple as unit checking out on a quick program. performed thoroughly, Agile improvement ends up in an important bring up in improvement potency and a discount within the variety of defects.
Apple has published unit checking out and code insurance frameworks for fast improvement in XCode. Up beforehand getting unit trying out up and operating in quick used to be no longer for the faint-hearted. fortunately now, there isn't any excuse except an absence of data on the place to get started.
iOS builders are confronted with their very own set of difficulties similar to tightly coupled code, fragmentation, immature trying out instruments all of which are solved utilizing latest Agile instruments and methods. After utilizing this publication, you are going to the best way to make your speedy apps agile and sound.

In the rest of the book, we’ll explore Agile testing in a lot more detail so you can see how to apply these techniques to your application to produce cleaner, faster code with fewer defects. 23 CHAPTER 2 Swift Unit Testing Swift’s implementation of unit testing uses the XCTest library. Swift does not use OCUnit for any unit testing. XCTest is easy to set up and works within Xcode, on the command line in OSX, or on the open source Linux version of Swift. In this chapter we take a deeper look at Swift unit testing.
Figure 2-1. swift internal class Now we can import the class using the @testable keyword, as shown in Figure 2-2. And we can now call the Calculator code and use it in our assertions. Figure 2-2.

For example, setup could include code to write to log files or create objects to be used in the test. setUp() saves you from having to repeat the calls in each test.
