To guarantee the quality of your iOS application, you should follow the Test-Driven development processes shown in below figure.
Test-Driven Development (TDD) is a Testing model which is applied to iOS application testing. In this model, a tester has to follow 4 phases below:
- Design: Figure out what you want to test, design your test cases
- Test: Run all tests and see if test cases fail
- Implement: Revise your code, fix bugs which cause the test to fail
- Test again: if Fail, if you roll back to the design. If all test cases Pass, the code meets the entire tested requirement.
In this iOS Automation Testing tutorial, you will learn
- iOS Automation Testing using Xcode
- Setting up Xcode Project for UI Testing
- How to Create iOS Automation using UI Automation Framework
- How to Create iOS Automation using OCUnit framework
- UI Automation Sample Code
To create iOS Test Program, you need a Mac Book.Your Mac has already installed:
- OS X. Operating system for Mac PC
- Xcode IDE, a development tool for iOS
- Automated Testing framework (UI Automation, OCUnit..)
- iOS SDK 4 (or higher)
Step 1) Launch Instruments
Open XCode ->Open Developer Tool ->Instrument
Step 2) Add Automation Instrument
In Instruments window, select Automation Instrument
To create a test script, you either record a Test Scenario or you program it manually.
Step 3) Press Red button
An instrument is launching, and Stop recording immediately. If you want to start the record, press Red button
Step 4) Create a new script
In the Scripts window, click Add > Create to create a new script
Step 5) Choose the target
You’re in the Trace window, use the Choose Target pull down to navigate to the debugging version of your App.
In this case, I will use Apple’s sample SimpleDrillDown simple app as an application under test. It has GUI below.
Step 6) Start record your script
Record your script by hitting the record button at the top or bottom of the tool.
Now you can do some UI action on your application under test, and your script is recorded.
Step 7) See your script
To see your script, hit the Trace Log/Editor Log drop down and switch to script log view.
You will see your recorded script.
Step 8) Play your script
Press play button, the script runs, and you can stop it after logs appear.
Step 1) Start Xcode IDE, Add Unit Test Bundle target
Step 2) Write the name of the new Unit test Bundle as the figure above, then click Finish
Step 3) Make Unit Test active target
Step 4) Add a group for test classes
Step 5) Add a Unit test class
Step 6) Now start your implement
OCUnit uses Objective-C language to create test program. The Developer must know about this language.
