Software Testing Estimation Techniques


Estimating effort for test is one of the major and important tasks in SDLC. Correct estimation helps in testing the Software with maximum coverage. This section describes some of the techniques which can be useful during the estimating of effort for testing.

Functional Point Analysis

This method is based on the analysis of functional user requirements of the Software with following categories:

  • Outputs

  • Inquiries

  • Inputs

  • Internal files

  • External files

Test Point Analysis

This estimation process is used for function point analysis for Black box or Acceptance testing. It is use the main elements of this method are: Size, Productivity, Strategy, Interfacing, Complexity and Uniformity etc.

Mark-II method

It is estimation method used for analysis and measuring the estimation based on end user functional view. The procedure for Mark-II method is:

  • Determine the View Point

  • Purpose and Type of Count

  • Define the Boundary of Count

  • Identify the Logical transactions

  • Identify and Categorize Data Entity Types

  • Count the Input Data Element Types

  • Count the Functional Size


You can use other popular estimation techniques like:

  • Delphi Technique

  • Analogy Based Estimation

  • Test Case Enumeration Based Estimation

  • Task (Activity) based Estimation

  • IFPUG method
