How do I correctly count the number of clicks in a usability test?

I'm unsure how I should count the number of clicks in a usability test conducted with mockups.

Say, for example, a user must complete the task of creating a new post. In this task the user will start on the homepage, so he needs to click the "Create New Post" button then he will go to a form to insert a title, select a category through a select menu, and complete other fields.

How should the number of clicks be counted?

The "Create New Post" should be a click, but then when the user is redirected to the create post page, in order for the user to write the title he needs to click in the input or use Tab. Is that a click?

Also for the user to select a category through a select menu he needs to select a category. That's also another click?

Does each input that the user needs to fill in count as a click in my usability test?
