* Apply PR #2297 to devel branch It turns out that Issue #2272 partially affected the devel branch. When building tests with C++20, the compiler emits a warning that top-level comma expressions in array subscripts are depricated. Warnings are treated as errors, so this caused the build to fail. This commit adds localized warning suppression in accordance with this recommendation here: https://github.com/catchorg/Catch2/pull/2297#discussion_r720848392 Signed-off-by: Alecto Irene Perez <perez.cs@pm.me> * Fixed unknown pragma warning on old versions of gcc & clang This commit fixes an unkwown pragma warning on older versions of GCC and Clang. These older versions don't have a warning for depricated use of the comma subscript. Because warning suppression is localized, and only refers to the comma subscript warning, it doesn't affect compiler warnings in other parts of the code.

Catch2 v3 is being developed!
You are on the devel branch, where the next major version, v3, of
Catch2 is being developed. As it is a significant rework, you will
find that parts of this documentation are likely still stuck on v2.
For stable (and documentation-matching) version of Catch2, go to the
v2.x branch.
For migrating from the v2 releases to v3, you should look at our documentation. It provides a simple guidelines on getting started, and collects most common migration problems.
What's the Catch2?
Catch2 is mainly a unit testing framework for C++, but it also provides basic micro-benchmarking features, and simple BDD macros.
Catch2's main advantage is that using it is both simple and natural. Tests autoregister themselves and do not have to be named with valid identifiers, assertions look like normal C++ code, and sections provide a nice way to share set-up and tear-down code in tests.
How to use it
This documentation comprises these three parts:
- Why do we need yet another C++ Test Framework?
- Tutorial - getting started
- Reference section - all the details
