Description

Testers never have enough time. But how long should we have to test? How long will enough testing take?

This course looks at current estimation techniques to aid accurate test estimation. The course covers several methods of estimation, with the positives and negatives for each method based on the experience Expleo has gained over the years working in many industries.

Course Objectives

By the end of the course, attendees, through instructor-led presentations, exercises, and discussions, will be able to:

  • Analyse risks to system quality to determine what should be tested—and to what degree—in a test subproject.
  • Use methods to develop a time estimate for an example designed project.
  • Present the estimate to management on a cost-relative, risk-management basis.
  • Adjust the estimated schedule and budget to fit project constraints without undermining accuracy or unduly increasing risk.
