The command you have mentioned is hardhat test ${filename1-js} ${filename2-js}.

Here's an explanation of each component in the command:

1. hardhat: This is a command-line tool used for Ethereum development. It provides a development environment, task runner, and testing framework.

2. test: This is a subcommand provided by Hardhat to run test cases. It executes test scripts written in Solidity or JavaScript.

3. ${filename1-js} and ${filename2-js}: These are placeholders representing two filenames with the .js file extension. They are command-line arguments passed to the hardhat test command. The specific filenames should be provided instead of ${filename1-js} and ${filename2-js}.

To execute this command successfully, you need to provide the actual filenames of JavaScript files you want to test in place of ${filename1-js} and ${filename2-js}.

For example, if you have two JavaScript test files named test1.js and test2.js, the command should be written like this:

hardhat test test1.js test2.js

This would execute the Hardhat test runner and run the tests defined in test1.js and test2.js files.
