Each of these components is provided by Microsoft as one or more extensions on the product DVD and in artifact feeds.
The Test Tool–being the C/AL Test Tool, see below–is also present in Business Central online, but you will only be able to fetch tests for the additional Microsoft extensions that reside in CRONUS, not for the base and system application. To get yourself a free trial, visit https://dynamics.microsoft.com/en-us/dynamics-365-free-trial/.
Details on how to set up your Business Central environment are discussed in Appendix, Getting Up and Running with Business Central, VS Code, and the GitHub Project.
