Since writing a test class to cover all of the facets of this class is not something that anyone on here will do for you, I can give you some pointers and hopefully get you started.  I would recommend that you do some reading on testing [1] [2] [3] to get a better understanding.  Each of your individual tests should only tests one specific portion of you class (ie a constructor test, sendEmail test, contactSelected test, etc).  You should also have both a postitive (everything works perfectly) and a negative (things are not right) test.

Each test should follow the following structure:
  • Setup of test data. This includes creation of any data needed by your class.  Account, Contacts etc
  • Starting the test. This is calling Test.startTest() to reset the governor limits
  • Calling your class / method
  • Stopping the test.This is calling Test.stopTest() to reset the governor limits and allow for any async jobs to finish
  • Asserting that your changes have worked
    • If you have inserted/updated/deleted data, you need to query for the updates
    • Run System.assert, System.assertEquals, System.assertNotEquals to verify that you got the correct data back
If you have any specific problems with your tests, feel free to create a new post with the part of the class you are trying to test and your current test method, and you will more likely get a better response then asking for someone to essentially write an entire test class for you.

NOTE: Please use the "Add a code sample" button (icon <>) when pasting code.  This will increase readability and give the responder line numbers they can use.

Rakesh,

I have to agree with pcon's point - it's hard to tell how to create a test class for your entire Apex controller. I typically approach the test class by identifying the key test scenarios and logical conditions and list each one of them as a test method (kinda similar of how you develop test scripts), even follow the similar steps pcon mentioned about for each test method.
