How do I test my iOS Apps

Question

My question maybe silly, but can anyone coach me?

Except doing some test(most likely white box testing) while coding, after the App was built, do we have some testin

Update: Added section 'Automated testing for iOS4'

As a professional tester my suggestion is that you should have a healthy mix of automated and manual testing. The Examples below are in .net but it should be easy to find a tool for whatever technique you are using.

AUTOMATED TESTING

• Unit Testing
  Use NUnit to test your classes, functions and interaction between them.

• Automated Functional Testing
  If it's possible you should automate a lot of the functional testing. Some frame works have functional testing built into them. Otherwise you have to use a tool for it. If you are developing web sites/applications you might want to look at Selenium.

• Continuous Integration
  Use CI to make sure all your automated tests run every time someone in your team makes a commit to the project.

• Automated testing for iOS4
  Automate the testing of your application by scripting touch events using the new UIAutomation Instrument.

MANUAL TESTING
As much as I love automated testing it is, IMHO, not a substitute for manual testing. The main reason being that an automated can only do what it is told and only verify what it has been informed to view as pass/fail. A human can use it's intelligence to find faults and raise questions that appear while testing something else.

• Exploratory Testing
  ET is a very low cost and effective way to find defects in a project. It take advantage of the intelligence of a human being and a teaches the testers/developers more about the project than any other testing technique i know of. Doing an ET session aimed at every feature deployed in the test environment is not only an effective way to find problems fast, but also a good way to learn and fun!
