Test plan

Introduction

In order to be able to present our design to potential buyers (Atlas), everything needs to be tested first. The aim of this test plan is to make sure that everything works as it supposed to work. If any defects are found, improvements to the design can be made in order to eliminate these errors. Every defect found can be categorised as being a critical, high, medium or low defect. Of course, the critical defects will be fixed first followed by the high, medium and low defects. The goal is to have in the end zero critical and high defects, and as less medium and low defects as possible. In the beginning, all individual components will be tested whether they’re working as well as the chains of these components before integrating them in our actual design. These are the unit and integration tests. Once our design is ready, the requirements will be tested first e.g. whether the monitor can move and rotate at all, do the cameras work, etc. When everything is all right, the thresholds and the min/max deviations can be installed. It will then be verified whether these are working by executing some more tests. These are the tests described in more detail below. Mainly these tests are about the detection of movement of the user. In case there is some time left, some negative testing can be done when desired. These are tests where one tries to let the device fail. By doing this, one can figure out how easy it would be to mislead the device.

Overview

Functional Requirements

  • Height of the screen to eyes and max deviation up down.
  • Centre of the screen to eyes and max deviation left right.
  • Rotation through X-Z plane.
  • Rotation through Y-Z plane.
  • Min/max distance eye to screen.
  • Brightness of the screen in comparison to external light.

Non-Functional Requirements

  • Minimum response time to adapt (all functional requirements except).
  • Maximum noise.
  • Custom made thresholds.
  • Input profile parameters.
  • Mandatory rest periods.
  • Reaction to resistance.

Test Types

  • Unit test: test individual components e.g. stepper motors. Executed by project team.
  • Integration test: test end to end chain of components. Executed by project team.
  • User test: test performed by an user. Executed by independent users.

Acceptance Criteria

  • Definition severity (critical-high-medium-low) of defects.
  • Threshold to accept product.

Test Scripts

  • Description of individual tests; describe expected results and obtained results.
