Unit Tests ​

Unit tests validate rule behavior using Bazel's analysis testing framework:

bash
bazel test //test/unit/...

Test coverage includes:

  • fortran_library and fortran_binary rules
  • Module propagation via FortranInfo
  • C/C++ interop via CcInfo
  • Dependency propagation
  • Edge cases and linking

Integration Tests ​

The examples/ directory is a separate Bazel module that imports rules_fortran. It serves as integration tests for real-world usage:

bash
cd examples
bazel test //basic:all //blas:all //omp:all
bazel build //wasm:hello_wasm //wasm:full_wasm //wasm:omp_hello_wasm

Test Coverage ​

  • 27 unit tests (providers, module propagation, interop, edge cases)
  • 9 BLAS tests -- from-source Netlib Level 1/2/3, all precisions (s/d/c/z)
  • 97 LAPACK tests -- from-source Netlib LIN, EIG, DMD, mixed precision, RFP across all precisions (5.2M individual test cases)
  • wasm32 runtime tests (hello, LAPACK, OpenMP+pthreads)
  • 10-platform CI matrix (5 OS x 2 Bazel versions)

Running CI Locally ​

bash
bazel test //test/... --verbose_failures --test_output=all
