These tests consist of various Python constructions (hopefully a somewhat comprehensive set) with specific timestamp annotations scattered throughout. When the tests are run using the Python 3 interpreter, these annotations are checked and compared to the "current timestamp" to see that they are in agreement. This is what makes the tests "self-validating". There are a few different kinds of annotations: the basic `t[4]` style (meaning this is executed at timestamp 4), the `t[dead(4)]` variant (meaning this _would_ happen at timestamp 4, but it is in a dead branch), and `t[never]` (meaning this is never executed at all). In addition to this, there is a query, MissingAnnotations, which checks whether we have applied these annotations maximally. Many expression nodes are not actually annotatable, so there is a sizeable list of excluded nodes for that query.
