This directory contains tests for the core WebAssembly semantics, as described in Semantics.md and specified by the spec interpreter.
This files should be a direct copy of the original WebAssembly spec tests.
Tests are written in the S-Expression script format defined by the interpreter.
Autogenerated Rust test cases
This files will serve as base for autogenerating Rust testcases
when WASM_GENERATE_SPECTESTS=1 cargo build
is executed
(src/build_spectests.rs).
The result autogenerated spectests live in the src/spectests directory.
Testcases
Currently supported command assertions:
- Module mostly implemented (it should support named modules
(module $Xx)
). - AssertReturn mostly implemented (it should support calls to named modules
(invoke $Xx "call")
). - AssertReturnCanonicalNan fully implemented
- AssertReturnArithmeticNan fully implemented
- AssertTrap fully implemented
- AssertInvalid Fully implemented (it should not require to do validation separate from compilation)
- AssertMalformed Fully implemented
- AssertUninstantiable not implemented yet
- AssertExhaustion not implemented yet
- Register not implemented yet
- PerformAction partially implemented, only function invokations for now

Specific non-supported cases
There are some cases that we decided to skip for now to fasten the time to release:
SKIP_MUTABLE_GLOBALS
: Right now the WASM parser can't validate a module with imported/exported mut globals. We decided to skip the tests until Cranelift and wasmparser can handle this (original spec proposal: https://github.com/WebAssembly/mutable-global). Spectests affected:globals.wast
SKIP_CALL_INDIRECT_TYPE_MISMATCH
: we implemented traps in a fast way. We haven't covered yet the type mismatch oncall_indirect
. Specs affected:call_indirect.wast
