k6: Run load test locally with a given environment variable.

$ k6 run -e ${HOSTNAME=example-com} ${script-js}

try on your machine

The command you provided is used to run a load testing script using the k6 tool. Here's the breakdown of the command:

k6 run: This is the main command to execute the k6 tool and run a load testing script.
-e ${HOSTNAME=example-com}: The -e flag is used to pass environment variables to the script. In this case, you are passing an environment variable named HOSTNAME with a default value of example-com. The syntax ${HOSTNAME=example-com} sets the value of HOSTNAME to example-com only if it is not already set.
${script-js}: This is the file path or name of the load testing script written in JavaScript that you want to execute.

So, when you run this command, k6 will execute the load testing script specified by ${script-js} and any environment variables that you've set, such as HOSTNAME with the default value of example-com, will be accessible within the script.
