Software Testing and Quality Assurance Techniques

Course:  STQA
Duration:  3 Days
Level:  I
Course Summary

The proper testing of software and quality assurance can save an organization time, effort and money. In this course, software professionals, quality assurance specialists and managers gain thorough knowledge of testing and QA approaches that need to integrated into the software development life cycle. Through hands-on exercises, you learn how to build testing methods into your work process to correctly design products that are functional and maintainable.

This workshop promotes a cohesive approach to QA and testing: a "how-to" approach with exercises, examples, and templates that can be applied immediately to quality assurance and testing procedures. It addresses the roles and responsibilities of each participant in the software development process. It outlines responsibilities, expectations, and mechanisms to measure performance and progress.

The workshop emphasizes a practical approach to testing in order to create better products and addresses the ever-changing needs and resources of an organization. Toward that end, we'll Investigate and use the 'V' Model, a process model which describes the graphical arrangement of the individual phases. The 'V' is also a synonym for Verification and Validation.
