+title: Testing Workgroup
+---
+
+The Testing Workgroup is a team that helps guide the experience, libraries, and
+tools for testing Swift code.
+
+The Testing Workgroup will:
+
+* Govern the [Swift Testing](https://github.com/swiftlang/swift-testing) and
+ [Corelibs XCTest](https://github.com/swiftlang/swift-corelibs-xctest) projects
+ and conduct reviews of their feature proposals.
+* Identify improvements which would address the needs of testing in the Swift
+ community.
+* Pursue long-term feature directions outlined in the Swift Testing
+ [vision document](https://github.com/swiftlang/swift-evolution/blob/main/visions/swift-testing.md).
+* Promote the integration of testing functionality and libraries in related
+ tools.
+* Channel feedback to other workgroups, steering groups, and the Core Team about
+ unmet testing needs of the Swift community.
+
+The current Testing Workgroup consists of the following people:
+
+{% assign people = site.data['testing-workgroup'].members | sort: "name" %}
+
+{% for person in people %}
+- {{ person.name }}
+{%- if person.affiliation -%}
+, {{ person.affiliation }}
+{% endif %}
+{% if person.handle %}
+(@{{person.handle}})
+{% endif %}
+
+{% endfor %}
+
+
+## Charter
+
+The ultimate goal of the Testing Workgroup is to enhance the experience and
+utility of authoring and running tests in Swift to improve software quality
+across the ecosystem. In pursuit of that goal, the workgroup develops libraries
+like Swift Testing which implement core functionality needed by the community;
+it coordinates with the maintainers of commonly-used tools, IDEs, and CI
+systems to integrate them and promote testing workflows; and when necessary, it
+collaborates with other Swift community groups to pursue testing-related
+improvements in their areas. Some areas of frequent collaboration with other
+groups include:
+
+* the `swift test` subcommand of
+ [swift-package-manager](https://github.com/swiftlang/swift-package-manager);
+* the testing subsystem in the
+ [vscode-swift](https://github.com/swiftlang/vscode-swift) plugin; and
+* the static test discovery logic in
+ [sourcekit-lsp](https://github.com/swiftlang/sourcekit-lsp).
+
+A central function of the workgroup is conducting community reviews of features
+and API proposals for the Swift Testing project. Its governance of that project
+is guided by its accompanying
+[vision document](https://github.com/swiftlang/swift-evolution/blob/main/visions/swift-testing.md).
+The workgroup also looks for opportunities to deepen integration of testing
+libraries with tools and IDEs, enable additional styles of testing (such as
+performance or UI), or to resolve problems which impact testing workflows.
+Members of the workgroup regularly evaluate emerging trends in the Swift
+ecosystem, and discuss how testing could better support them.
+
+## Membership
+
+Membership in the Testing Workgroup is contribution-based and expected to
+evolve over time. Adding new members and removing inactive ones is subject to a
+vote by the existing members and requires unanimous agreement. Membership is
+limited to ten members in total to keep the group small enough to be effective.
+
+The Core Team selects one member of the workgroup as the chair. The chair has no
+special authority over the workgroup, but they are responsible for ensuring its
+smooth functioning, including by:
+
+* organizing and leading regular meetings,
+* ensuring that the workgroup communicates effectively with the community, and
+* coordinating meetings between workgroup representatives and other Swift
+ workgroups or teams when necessary.
+
+If you’d like to join the workgroup, send a message to
+[@testing-workgroup](https://forums.swift.org/new-message?groupname=testing-workgroup)
+on the Forums and you will be invited to the next available group meeting to
+discuss it more. See [Community participation](#community-participation) for
+examples of ways to contribute and demonstrate your interest to the group.
+
+Workgroup members will try to make a decision independently by consensus
+whenever possible, and will raise issues to the Core Team when there are
+particular challenges with reaching consensus on significant decisions.
+
+## Meetings
+
+The Testing Workgroup meets biweekly on Monday at 1:00PM PT (USA Pacific).
+Meetings take place in [even numbered weeks](http://www.whatweekisit.org/),
+unless otherwise communicated in advance.
+
+Many workgroup meetings are meant for open discussion and any Swift community
+member may attend by sending a message to
+[@testing-workgroup](https://forums.swift.org/new-message?groupname=testing-workgroup)
+beforehand to request an invite. Some meetings are reserved for private
+discussion by group members, for example to make a decision on a proposal under
+review.
+
+## Communication
+
+The Testing Workgroup communicates with the broader Swift community in the
+[swift-testing](https://forums.swift.org/c/development/swift-testing/103)
+Forum category. The workgroup can also be contacted privately by sending a
+message to
+[@testing-workgroup](https://forums.swift.org/new-message?groupname=testing-workgroup).
+
+If any significant decisions are reached during one of the workgroup's regular
+meetings, a member will post about them in the Forums within one week. The
+outcome of each proposal review will be announced by its review manager in a
+separate thread dedicated to that proposal.
+
+## Community participation
+
+Everyone is invited to help improve Swift’s testing experience and participate
+in the Testing Workgroup’s initiatives. Here are some ways to consider
+participating:
+
+* Discuss ideas on the Swift Forums. You can create new topics in the
+ [swift-testing](https://forums.swift.org/c/development/swift-testing/103)
+ category, or add the `testing` tag to any topic.
+* Open GitHub issues to track enhancements or report bugs in the projects
+ governed by the Testing Workgroup, such as
+ [swift-testing](https://github.com/swiftlang/swift-testing).
+* Contribute bug fixes or enhancements to
+ [swift-testing](https://github.com/swiftlang/swift-testing). (See
+ [CONTRIBUTING](https://github.com/swiftlang/swift-testing/blob/main/CONTRIBUTING.md).)
+* Expand [swift-testing](https://github.com/swiftlang/swift-testing) to support
+ additional platforms. (See
+ [Porting](https://github.com/swiftlang/swift-testing/blob/main/Documentation/Porting.md).)
+* Develop new tools to aide automated testing or improve existing ones.
+* Provide feedback to the members of the Testing Workgroup directly by sending a
+ message to
+ [@testing-workgroup](https://forums.swift.org/new-message?groupname=testing-workgroup)
+ on the Forums. The workgroup chair brings outstanding issues and topics to the
+ workgroup to discuss during regular meetings. The workgroup decides the
+ actions for the issues.
+* Join the Testing Workgroup’s regular video meetings. Send a message to
+ [@testing-workgroup](https://forums.swift.org/new-message?groupname=testing-workgroup)
+ to request access, since calls must be kept to a relatively small number of
+ participants.
