Can we please add tests for this code path as well? I understand we don't have existing test for this action. but you should be able to create one similar to the StartHostActionTests and other action tests.

Hi @kshyju, I saw some tests are added in the InitTests.cs class (contains all cli test cases of Init action) for the Init action. Do I need to create a new class similar to StartHostActionTests to add tests or need to add it the InitTests.cs?
