Test Accounts are secondary accounts which belong to a specific scratcher. These accounts are sometimes made to mess around with Scratch, test features, enter contests, make remixes, etc while keeping a reputation on their main account. They are very common, especially among very active scratchers.
Identifying Test Accounts
Usually, test accounts will have "test" or "labs" in their name. Sometimes, test accounts will appear to be the same name as the main account by replacing "l"s with capital "i"s. For example, a users name might be "Example" and their test account would be named "ExampIe", with a capital "i". This sometimes makes the test account harder to find in the search bar.
Common Uses of Test Accounts
Often, to avoid getting users excited about a new real project, users will share contests on their test account instead of their main.
Users sometimes use their test account to share tutorials on how to do things they did in projects on their main account. Tutorials might not always go on a test account. Test accounts might also be used to share tutorials on different features to support and help the Community.
Trailers & Previews
In another attempt to avoid confusion of a real project with their followers, users often share previews and trailers on their test account. These are generally to create an excitement for a project, share updates about what is happening with the project, and test different features that will be included in the project.
Users may share projects on their test account which have been done on the main account but the process was cancelled. This might be the result of reduced dedication, lack of time, or the project being too complicated. Usually, cancelled projects may be incomplete and buggy.
Users might share projects that are complete on their test account because they are not big enough to be shared on their main. For an example, a cool pen effect might not be big enough for the main account, but the user still wants to share it with the Community.
Some users share old projects which they consider not high enough quality to go on their main accounts, on their test accounts. Often a user may "redesign" their account to make it look better, and move any projects that are not of high enough quality over to their test account.
