On the below test code I am covering 53% and have an error that says the following:

TestQuoteExt.basicAttachTest

	System.QueryException: List has no rows for assignment to 
SObject	

Class.quoteExt.attachQuote: line 17, column 23 Class.TestQuoteExt.basicAttachTest: line 42, column 32 External entry point

I am running agains a brick wall. How to I solve this error in the test class?

Test Class:
