The extension needs to be installed by all participants of the VS Live Share session. Now the guests of a VS Live Share session will be able to see and interact with the host's tests.
the Code Lenses for starting the tests are currently not shown on the guest side of the session.
Guests will have to use the Test Explorer view or its
for starting the tests.
only the events from the Test Adapters are shared between the host and the guests. This means
that if the host or a guest enables autorun or resets/retires the test states, this will not
be visible to the other participants of the session.
The extension creates an Output Channel called Test Explorer Live Share containing detailed logs.
If you can't figure out why something isn't working, please
file a bug report and include these logs.
