Overview

Purpose

Detail the purpose of this document. For example:

  • The test scope, focus areas and objectives
  • The test responsibilities
  • The test strategy for the levels and types of test for this release
  • The entry and exit criteria
  • The basis of the test estimates
  • Any risks, issues, assumptions and test dependencies
  • The test schedule and major milestones
  • The test deliverables

Scope

This wiki details the testing that will be performed by the project team for the FLAC support project. It defines the overall testing requirements and provides an integrated view of the project test activities. Its purpose is to document:

  • what will be tested,
  • how testing will be performed.

Testing summary

Scope of Testing

In Scope

Testing efforts will be focused on confirming that FLAC support is working as expected for eligible audio content.

Out of Scope

The full functionality of the FLAC (Free Lossless Audio Codec) is not included in the testing efforts. Only Firefox support for the FLAC audio feature is tested. Although, a smoke will be run on the functionality part.

Requirements for testing

Environments

Full testing will be done on following OSes:

  • Windows 7
  • Windwos 10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS
  • Mac OS X 10.11 or greater

What is FLAC?

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo) just like you would an MP3 file.

FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.

Test Objectives

This section details the progression test objectives that will be covered. Please note that this is at a high level. For large projects, a suite of test cases would be created which would reference directly back to this master. This could be documented in bullet form or in a table similar to the one below.

Ref Function Test Objective Evaluation Criteria Test Type Owners
1 FLAC support core functionality is intact on web sites with eligible content Verify that all the core functionality associated to FLAC support works properly The options available for this file format work as expected Manual Desktop Team
