Database :Auto increment in SQL server ID

Question

Hi,
How can I do auto increment in SQL server primary column ID. Actualy I am writing the data into the SQL datbase table using LabVIEW and I wanted to set the auto increment to the primary key column ID.  I have three column in TEST_REPORT table i.e  Test_ID, Test_No and Test_Result. I wanted to set Test_ID as a primary key and set as a auto increment and write the value for only Test_No and Test_Result column
When ever I am writing data into table the Test_ID is not getting auto incremented. I set that auto increment manualy through SQL server management studio.
Please help me to fix this issue.

Hi Palanivel,
Thanks for the suggestion.
Initially I was using same logic "query for TEST ID at initially"  but I have to query data from more than 20 tables  and write into it and its taking lots of space and query time.
I am just looking for alternative of this. 
Actually I am setting the auto incremnt  for TEST ID  through the SQL server managemnt studio but when ever I ignore the TEST ID column and write the data in rest column.  
I gets the error message  "Insert Error: Column name or number of supplied values does not match table definition".
