C++ example for benchmarking with [Catch2 Framework][tool]
2+
====================================================================
3+
4+
- [Workflow for this example](../../.github/workflows/catch2.yml)
5+
- [Action log of this example](https://github.com/benchmark-action/github-action-benchmark/actions?query=workflow%3A%22Catch2+C%2B%2B+Example%22)
6+
- [Benchmark results on GitHub pages](https://benchmark-action.github.io/github-action-benchmark/dev/bench/)
7+
8+
This directory shows how to use [`github-action-benchmark`][action] with [Catch2 Framework][tool].
9+
10+
11+
12+
## Run benchmarks
13+
14+
Official documentation for usage of Catch2 Framework can be found in its repository:
15+
16+
https://github.com/catchorg/Catch2
17+
18+
Since Catch2 is a header-only test framework, you don't need to build it in advance.
19+
Download and put the headers in your `include` directory and write your benchmarks.
20+
21+
```cpp
22+
#define CATCH_CONFIG_MAIN
23+
#include <catch2/catch.hpp>
24+
25+
TEST_CASE("Fibonacci") {
26+
// now let's benchmark:
27+
BENCHMARK("Some benchmark") {
28+
// Your benchmark goes here
29+
};
30+
}
31+
```
32+
33+
Build the source with C++ compiler and run the built executable to get the benchmark output.
34+
Ensure to use `console` reporter for this. `xml` reporter may be supported in the future.
35+
36+
37+
38+
## Process benchmark results
39+
40+
Store the benchmark results with step using the action. Please set `catch2` to `tool` input.
41+
42+
```yaml
43+
- name: Store benchmark result
44+
uses: benchmark-action/github-action-benchmark@v1
45+
with:
46+
tool: 'catch2'
47+
output-file-path: benchmark_result.json
48+
```
49+
50+
Please read ['How to use' section](https://github.com/benchmark-action/github-action-benchmark#how-to-use) for common usage.
51+
52+
53+
54+
## Run this example
55+
56+
To try this example, please use [cmake](./CMakeLists.txt) and `clang++`.
57+
58+
```sh
59+
$ mkdir build
60+
$ cd build
61+
$ cmake -DCMAKE_BUILD_TYPE=Release ..
62+
$ cmake --build . --config Release
63+
```
64+
65+
This will create `Catch2_bench` executable. The results are output to stdout.
66+
67+

68+
[action]: https://github.com/benchmark-action/github-action-benchmark
