TC-SC-7.1: Add test for unique discriminators (#34407)
* TC-SC-5.1: Add test for unique discriminators see CHIP-Specifications/connectedhomeip-spec#9117 Test: please see test_testing for unit tests. * Restyled by autopep8 * Restyled by isort * rename test to TC-SC-7.1 TC-SC-5.1 exists, it's just in a different section. * linter * make setup codes empty lists by default * fix basic comp * fix qr code in ci * Fixup manual codes * Restyled by autopep8 * linter --------- Co-authored-by: Restyled.io <[email protected]>
