Thanks to spec tests (opens in a new tab) we can ensure 100% compatibility with the WebAssembly spec test suite.

You can run all the tests with:

make test

make test will automatically detect the compilers available on your system.

Please follow the Building from Source guide see how you can prepare your system with the requirements needed for each of the backends.

Testing Compilers

Each compiler integration can be tested separately:

  • Singlepass: make test-singlepass
  • Cranelift: make test-cranelift
  • LLVM: make test-llvm
