📝 Walkthrough

Walkthrough

The pull request introduces a modification to the isBrb method in the MemberUtil object within the @webex/plugin-meetings package. The change involves adding optional chaining to the controls property when accessing the brb.enabled value. This update ensures that if the controls property is undefined or null, the method will not throw an error and will instead return false.

Correspondingly, a new test case is added to the unit tests for the MemberUtil.isBrb function. The new test verifies the method's behavior when the participant object lacks a controls property, specifically checking that it returns false for an empty participant object. This change improves the robustness of the method by expanding its test coverage.

packages/@webex/plugin-meetings/src/member/util.ts (1)

60-60: LGTM! The optional chaining operator handles undefined controls correctly.

The implementation safely handles cases where participant.controls is undefined while maintaining the function's boolean return type contract.

packages/@webex/plugin-meetings/test/unit/spec/member/util.js (1)

389-393: LGTM! Test coverage is comprehensive.

The new test case properly verifies the handling of undefined controls, completing the test coverage for all edge cases.

@antsukanova , could you expand a little on the manual tests performed? Will be helpful

[antsukanova]

@adhmenon I have added context in the description, but this PR needed to fix client e2e test cases that don't work when controls are undefined, you check here details here https://sqbu-github.cisco.com/WebExSquared/webex-web-client/pull/7404
I have tested manually web client if controls are undefined it will not fail.
