## Making a Simulation Test
If you have KCL code that you want to test, simulation tests are the preferred way to do that.
Make a new sim test. Replace `foo_bar` with the snake case name of your test. The name needs to be unique.
```shell
just new-sim-test foo_bar
```
It will show the commands it ran, including the path to a new file `foo_bar/input.kcl`. Edit that with your KCL. If you need additional KCL files to import, include them in this directory.
Then run it.
```shell
just overwrite-sim-test foo_bar
```
The above should create a bunch of output files in the same directory.
Make sure you actually look at them. Specifically, if there's an `execution_error.snap`, it means the execution failed. Depending on the test, this may be what you expect. But if it's not, delete the snap file and run it again.
When it looks good, commit all the files, including `input.kcl`, generated output files in the test directory, and changes to `simulation_tests.rs`.
## Bumping the version
If you bump the version of kcl-lib and push it to crates, be sure to update the repos we own that use it as well. These are:
