 ## Running Tests
 
 Before we get to testing, we should add a test. Move Compiler supports tests written in Move and provides the execution environment. The tests can be placed in both the source files and in the tests/ folder. Tests are marked with the #[test] attribute and are automatically discovered by the compiler. We explain tests in depth in the Testing section.

 Here we import the hello_world module, and call its hello_world function to test that the output is indeed the string "Hello World!". Now, that we have tests in place, let's compile the package in the test mode and run tests. Move CLI has the test command for this:
 
 ```bash
-# from `hello_world` folder
 $ sui move test

+Test result: OK. Total tests: 1; passed: 1; failed: 0

 $ sui move test --path hello_world
