TPO-06: Usability testing

Test description:

The application follows usability guidelines and provides a good user experience.

Steps to conduct the test:

  1. Start the application.

  2. While using the application, check that these guidelines are followed:

Text and selections

  • Correct Note types are used in different situations.

  • Error notes are valid, informative, and easy to understand.

  • Terminology is not too technical but familiar to target users.

  • Text is not ALL CAPS; only the first word begins with a capital letter.

  • Truncated text or abbreviations do not exist.

  • Grammatical mistakes do not exist.

  • Terms and sentences that may cause misunderstandings are not used.

  • Images do not substitute for essential text.

  • Editable components are in the correct format when starting to edit them (numeric, alphabetic).

  • Editable components do not accept invalid input and give an understandable error note if invalid input is given.

  • Radio button and multi-selection lists are used correctly. If the user has only one option to select, a radio button list is used.

Layout and navigation

  • Every screen is easily readable.

  • The screen is fully used when applicable.

  • Text has good contrast with the background.

  • When possible, the application uses prefilled forms to support the user in writing.

  • By default, lists loop and have a scroll bar on the right side (from S60 2nd Edition, FP2 onwards).

  • Navigation is clear and intuitive and follows the same logic as the system applications.

  • If a grid component is used in a tabbed pane, it must be clear how to navigate between the tabs and scroll the grid horizontally.

Exit, Cancel

  • Exit is available in the Options list (S60).

  • Pressing the End key (red key) closes the application (from S60 2nd Edition, FP2 onwards).

  • User is able to reverse the actions.

Expected test result:

Usability guidelines listed in the testing steps are followed.

Different notes are used correctly according to the S60 UI Style Guide (see Section 6.7, “Notes”).
