 The tests for the standard library are located in `compiler/test/stdlib`. Since the standard library tests are written in Grain, rather than running the whole test suite, you can just run them directly:
 
 ```bash
-grain compiler/test/stdlib/array.test.gr
+grain compiler/test/stdlib/array.test.gr --stdlib stdlib
 ```
 
 If there's no error, you're all set.
