@garg3133 added some tests.

@dikwickley I just found out that we in fact already have the implementations for the computedrole and computedlabel under the command names of getAriaRole and getAccessibleName. So, instead of creating a new command for these two, we just need to add aliases in the existing commands (along with added test cases in the existing test files and types).

Also, for the isActive command, it would be better to use the endpoint itself (following the standards). I see a method already present in the method-mappings file for getting the active element, we could use that method inside the isElementActive method to get the element id of the currently active element and then compare it with the id of the element passed. Also, the isActive command would also require some basic tests.
