## Testing tests on wasi (wasm32-wasip1)
353+
354+
Some tests are specific to wasm targets.
355+
To run theste tests, you have to pass `--target wasm32-wasip1` to `x test`.
356+
Additionally, you need the wasi sdk.
357+
Follow the install instructions from the [wasi sdk repository] to get a sysroot on your computer.
358+
On the [wasm32-wasip1 target support page] a minimum version is specified that your sdk must be able to build.
359+
Some cmake commands that take a while and give a lot of very concerning c++ warnings...
360+
Then, in `bootstrap.toml`, point to the sysroot like so:
361+
362+
```
363+
[target.wasm32-wasip1]
364+
wasi-root = "<wasi-sdk location>/build/sysroot/install/share/wasi-sysroot"
365+
```
366+
367+
In my case I git-cloned it next to my rust folder, so it was `../wasi-sdk/build/....`
368+
Now, tests should just run, you don't have to set up anything else.
