Effectiveness in Testing

No matter how much testing is performed, if the test coverage is not adequate at all points in the project, the system may contain unrevealed defects or deficiencies.

Thus the buyers of a system—and their subject matter experts (both technical and operational)—must have input into the acceptance test design and content. This should happen at three points:

  • The initial system requirements and specifications.
  • The development of the test plan.
  • The final review of the test plan.

Real-World Test Scenarios

Acceptance testing must demonstrate that the system will at least perform adequately in the way that the system is intended to be used . Final tests must be done with the system configured for live use, using real-world data and realistic test scenarios.

Types of Tests

There are many types of tests such as stress and load tests, performance tests, failure tests, and functional tests.

There are several categories of testing such as unit testing (test of various components individually—such as card readers or video analytics), integration testing (test that components work together properly) and systems testing (testing how the system functions as a whole).

When and where do you do how much of each?

How much testing is too much? Or too little?

The buyers and users of the system will want to focus on how they plan to use the system on a daily basis. This is as it should be, but it’s usually not enough of a knowledge base to develop a sound acceptance test plan.

Someone expert in the types of tests required must see that the test plan contains:

  • a valid test approach
  • appropriate test cases
  • reliable test procedures
  • correct test system configuration
  • proper test environment
  • clear description of expected test outcomes
  • valid test pass/fail criteria
  • tests appropriate for the technologies employed
  • proper testing of packaged software components

The small investment of expert time that will be involved in reviewing (and if necessary, revising) the test plan will make a big contribution towards a successful system turnover.
