I am working on a machine-learning invention that can be applied in the narrow field in which I work (mainframe system programming). My English is not supreme but I need to define what I am working on (for marketing and documentation purposes) very business-y and correctly.

Let me explain what is the thing I am looking a word (or expression) for: We have 500 tests that are run in parallel. They aim at simulating a typical mainframe load while the testware sniffs for a system failure. Once a system failure occurs, the current modus operandi is that I, MANUALLY, try to reduce the 500 test set to a subset (I call it "the special mix") that will reproduce the problem but with less noise and less functionality being tried (leading to faster root cause analysis).

Hence, I am looking for the "test or tests that, when run, causes the system failure"... Well, the test doesn't "cause" the failure... The system developer allowed the logical error into the code... "Relevant" also doesn't work... All the tests are relevant :)

The best I have right now: "exact scope subset that reproduces the failure".

Any ideas?

  • 'Fire & Hit Test Suite', as when you press the start button to fire (execute) the selected test cases (i.e. your subset) they will hit your target (i.e. to reproduce the defect). if you want to go more deeper then use (F3) 'Fire & Found Failures', such words look more impressive in documentation, especially for getting reader's attention. – Dhiman Sep 24 '15 at 14:29
  • @Dhiman, I have to disagree :) Especially when concerning IBM stuff. There's zero room for fun there :) – DraxDomax Sep 25 '15 at 14:50

How about somethings like:

minimized failure reproduction set

Googling for this I found some research people are doing tring to automate this:

  • Yes, Minimal Failure Reproduction Set works quite well. Thanks. – DraxDomax Sep 25 '15 at 14:52
