Update catch2 v3 by josephleekl · Pull Request #1350 · PennyLaneAI/pennylane-lightning

josephleekl · 2026-03-02T19:24:06Z

Context:

Description of the Change:
Here we update Catch2 from v2.8 to v3.11.0.
Note for MPI tests we need a --order decl flag to ensure the tests are executed in declaration order, otherwise it will be randomized causing crash/hang.

Benefits:
Reduced CI build time - around 45min of CI time saved

LK CUDA C++ 18m22s -> 14m23s
LK-MPI-CUDA-C++: 22m25s->17m22s
LG-MPI-C++: 53m44s -> 48m24s
LG-C++: 40m33s -> 37m43s
LT-C++: 6m31s -> 4m45s
LQ-C++ (OMP-off, AVX-off): 12m51s -> 7m30s
LQ-C++ (OMP-on, AVX-off): 14m58s -> 8m30s
LQ-C++ (OMP-off, AVX-on): 13m59s -> 7m16s
LQ-C++ (blas-on): 13m3s -> 7m36s
LK-OMP-C++: 13m59s -> 12m17s
LK-multibackend-C++: 4m45s -> 3m41s

Small comment, but it looks like elsewhere you use Catch::Matchers::Approx but for some files you have using Catch::Approx. There are more occurrences of this than just the 3 here

Pull request overview

This PR upgrades the C++ test framework from Catch2 v2.x to Catch2 v3.11.0 across the repository, updating test runners, includes/macros, and CI/MPI invocation flags to keep test execution stable (notably for MPI tests).

Changes:

Bump Catch2 FetchContent tag to v3.11.0 and update CMake integration path (contrib → extras).
Migrate test runners to Catch::Session() and update test sources to Catch2 v3 modular headers/matchers (e.g., ContainsSubstring, Catch::Matchers::Approx).
Ensure MPI test execution order is deterministic by adding --order decl in Makefile and relevant GitHub Actions workflows.
