# Testing Thanks to [WebAssembly spec tests](https://github.com/wasmerio/wasmer/tree/master/lib/spectests/spectests) we can ensure 100% compatibility with the WebAssembly spec test suite. You can run all the tests with: ```text make test ``` > [!INFO] > `make test` will automatically detect the compilers available on your system. > > Please follow the [Building from Source](./BUILD.md) guide see how you can[ prepare your system with the requirements needed for each of the backends](./#all-backends-default). ## Testing Compilers Each compiler integration can be tested separately: * **Singlepass**: `make test-singlepass` * **Cranelift**: `make test-cranelift` * **LLVM**: `make test-llvm`
