Test Closure Document is the note prepared before u 
formally completes the testing process. This note contains 
the numbers of testcases executed, no. of defects found, 
Defect density, Slippage ratio, consolidated test result 
report etc. are  included. In simple, its the report on 
what u did during the testing process.

i think the test closure document is nothing but the test 
summary report which we give after the whole testing is 
finished....it gives panoramic view of total test result 


it contains 

            1.Total number of test cases

            2.Total number of bugs found

            3.Number of bugs resolved(fixed)

            4.Number of Bugs rejected

            5.Total number of bugs differed......tec
