In the course preview, I did not notice references to a crucial stage of software development of a certain level. Testing In developing SaaS systems that make use of artificial intelligence, what types of testing are adopted? Will there be a part of the course devoted to testing practices of the application since it should go into production? thanks @Brandon Hancock

Before starting the paid course I wanted to ask a question. With a view to building a SaaS product that communicates with one (or more) paid AI services through API calls. Usually these software offer subscription plans that include a number of features How do I determine a fair set of features to include in a paid plan? How do I calculate subscription prices that allow for the delivery of service expectations and at the same time have a certain profit? What kind of approach can be used to establish this information at the design stage and in any case before starting software development? Thanks @Brandon Hancock
