organize tests in "chapters" / label a set of tests

[SNAnalyst]

I often use many dozens of tests for the testing of a single function and include those inside a single testing file. It would be very useful if I could label tests or label/title/name a block of tests, so that it is easy to see which test failed.
Currently, I see that 78 tests passed and then an error occurred. But it is often not at all obvious which test actually failed. If tests can be labelled, or if a block of tests can be labelled (when using a block of tests to test a specific aspect of the tested function), then it should be possible to see that test "XYZ" failed or that a test from block "ZYX" failed. That can speed up error finding enormously.

Could it be made possible to label tests or to jointly label a block of tests and then access that label when a test file fails?

(I know there is an "info" argument, but that is not the same, I guess)
