Rust disable all tests for specific target

I am working on a Rust crate and I would like to disable all tests for one specific target architecture (wasm32). I know you can disable specific source items using a cfg annotation:

#[cfg(not(target_arch="wasm32"))]
#[test]
fn only_compile_on_not_wasm32() {
    ...
}

But as I want to disable all tests, I would like a quicker way, preferably as a configuration in the Cargo.toml file. The crate looks like this:

├── Cargo.toml
├── src
│   ├── ...
│   └── lib.rs
└── tests
    ├── ...
    └── mod.rs

i.e. the tests I want to disable are stored in the tests directory.
