Mobile Web Initiative Test Suites Working Group Charter

The mission of the Mobile Web Initiative Test Suites Working Group, part of the Mobile Web Initiative Activity, is to help create a strong foundation for the mobile Web through the development of a set of tests suited for browsers on mobile devices.

Software providers need tests to ensure that their products correctly implement the W3C technologies required for mobile Web access. The MWI Test Suites Working Group allows sharing the development cost of test suites within the community.

The main objective of the MWI Test Suites Working Group is to enable the development of a rich mobile Web experience by providing tests suited to user agents on mobile devices.

These tests can then be used by developers of user agents to increase the quality of their software, and by other actors in the market to advocate for better standards support, and to use the knowledge gathered on user agents to develop content that will work well across a large set of devices.

The scope of the MWI Test Suites Working Group includes:

W3C Groups

Mobile Web Initiative
The MWI Test Suites Working Group exists within the framework of the Mobile Web Initiative, currently comprising the Mobile Web Best Practices WG and the Mobile Web For Social Development Interest Group. The Chairs of the MWI Test Suites Working Group will sit on the MWI Steering Council.
Web Applications Working Group
The Mobile Web Test Suites Working Group will work with the Web Applications Working Group on developing tests for the specifications that are particularly relevant in mobile space, e.g. Widgets
CSS Working Group
The Test Suites Working Group will assist the CSS Working Group on the test suites needed for the progress of CSS Mobile Profile.
Other Interaction and Ubiquitous Web Domain groups
The Test Suites Working Group will assist other working groups that develop mobile-relevant technologies, e.g.:
  • the Ubiquitous Web Applications Working Group
  • the Geolocation Working Group
  • the HTML Working Group
  • the SVG Working Group
Hypertext Coordination Group (HCG)
The Hypertext Coordination Group ensures that all W3C Working Groups creating document specifications review each other's work. The MWI Test Suites Working Group expects to be represented on the Hypertext Coordination Group.

External Groups

Open Mobile Alliance IOP-Browsing group

The Open Mobile Alliance (OMA) InterOperability Process (IOP) group has a sub-Working Group dedicated to browsing technologies, working on a set of interoperability test suites for mobile Web technologie.

While the scope of the work done by the MWI Test Suites group and this OMA group differ (conformance vs interoperability test suites), the MWI Test Suites Working Group intends to develop a strong working relationship with OMA IOP Browsing by making use of the W3C-OMA liaison agreement which defines basic inter-working principles between the two bodies, as well as through the collaboration agreement on test suites set up between the W3C and OMA on CSS MP and XHTML MP test suites.


Effective participation to Mobile Web Initiative Test Suites Working Group is expected to consume one work day per week for each participant.

Participants are reminded of the Good Standing requirements of the W3C Process.


This group primarily conducts its work on the public mailing list public-mwts@w3.org (archive); the member only mailing list member-mwts@w3.org is used for administrative and logistics questions .

Information about the group (deliverables, participants, face-to-face meetings, teleconferences, etc.) is available from the Mobile Web Initiative Test Suites Working Group home page.
