| ## Eigen CI infrastructure |
| |
| Eigen's CI infrastructure uses three stages: |
| 1. A `checkformat` stage to verify MRs satisfy proper formatting style, as |
| defined by `clang-format`. |
| 2. A `build` stage to build the unit-tests. |
| 3. A `test` stage to run the unit-tests. |
| |
| For merge requests, only a small subset of tests are built/run, and only on a |
| small subset of platforms. This is to reduce our overall testing infrastructure |
| resource usage. In addition, we have nightly jobs that build and run the full |
| suite of tests on most officially supported platforms. |
