Correct Answer: Time Estimation method for Testing Process: Step 1 : count number of use cases (NUC) of system Step 2 : Set Avg Time Test Cases(ATTC) as per test plan Step 3 : Estimate total number of test cases (NTC) Total number of test cases = Number of Use Cases X Avg Test Cases per a use case Step 4 : Set Avg Execution Time (AET) per a test case Step 5 : Calculate Total Execution Time (TET) TET = Total number of test cases * AET Step 6 : Calculate Test Case Creation Time (TCCT) usually we will take 15 times of TET as TCCT TCCT = 15 * TET Step 7 : Time for Re-Test Case Execution (RTCE) this is for retesting usually we take 05 times of TET RTCE = 05 * TET Step 8 : Set Report generation Time (RGT usually we take 02 times of TET RGT = 02 * TET Step 9 : Set Test Environment Setup Time (TEST) it also depends on test plan Step 10 : Total Estimation time = TET + TCCT+ RTCE + RGT + TEST + some buffer
