Certification Mode - Fix pre-selection of test cases absent from the uploaded PICS - #354
Conversation
📝 WalkthroughWalkthroughThe applicable test-case selection logic now excludes test cases without PICS unless their collection is mandatory or they are explicitly selected. Tests cover mandatory and non-mandatory no-PICS cases. An integration-style test also verifies selection for uploaded clusters, absent clusters, and no-PICS cases.

Thanks for this — we hit exactly the same issue on a real DUT, and TC-SWTCH-2.x is our example too. For context: we're certifying a Matter device on this harness (backend |

Summary
Fixes an issue where Certification Mode pre-selected, and therefore forced the execution of, test cases belonging to clusters with no presence in the project's uploaded PICS (test cases whose scripts declare no PICS were treated as always applicable, in every collection), by auto-including test cases without declared PICS only when they belong to a mandatory collection or are explicitly named in the platform certification test list.
The issue
The applicable-test-cases computation carries a rule from the first TH release: a test case that declares no PICS is always applicable. At the time, the only tests without PICS were universal protocol tests, and this rule was the only way to keep them selected. Two things changed since:
pics_(about 55 script files at the current SDK pin), and each of them inherits always-applicable status.As a result, Certification Mode, whose selection is locked to the applicable set, forces test cases such as TC-SWTCH-2.x or TC-SEAR-1.x into runs for devices whose PICS never mention those clusters. Per the TH User Guide, in Certification Mode "a test case must be executed if and only if the PICS files indicate that it is applicable". Note this change also means that any non-mandatory test case without declared PICS is no longer pre-selected in either mode.
