Test point analysis (TPA) is a technique to measure the black box test effort estimation. The estimation is for system and acceptance testing. The technique uses-function point analysis in estimation.

TAP calculates the test efforts estimation in test points for highly important functions, according to user and for whole system. As the test points of functions are measured, the tests can test important functionalities first then be predicting the risk in testing.

This technique also consider the quality characteristics, such as functionality, security, usability, efficiency, etc. with proper weighting process for calculating TAP –

i) Dynamic and static test points are calculated. Dynamic test points are number of test which are based on dynamic measurable quality. Characteristic of functions in system. To calculate dynamic test point.

• Function points (FPs) assigned to function.

• Function dependent factor (FDC) such as interfacing, function importance, etc.

• Quality characteristics (QC)

Static test points are number of test points which are based on quality characteristics of system, it is calculated based on –

• Function points (FPs) assigned to system.

• Quality requirements or test strategy for static quality requirements (QC)

ii) Dynamic test point is added to static test point. To get total test points (TTP) for system.

iii) TTP is used for calculation of primary test hours (PTH) PTH is effort estimation for primary test hour’s activity such as preparation for primary test hour’s activity such as preparation, specification and execution.

iv) PTH is calculated based on environmental factors and productivity factors.

v) Secondary testing activities include management activities like controlling the testing activities.

vi) TTH is calculated by adding some allowance to secondary activities and PTH.

vii) Thus TTH is final effort estimation for testing activities.
