wws --help

Install k6

brew install k6

Extras

Create your K6 Grafana Cloud here.

Login to k6

k6 login cloud --token <YOUR_TOKEN>

Create a k6 load test

# under the specific directory (eg. ssr) do this
k6 new
# this command will create a new default `script.js` file

# or you can create your own as follows:

Update the test file content like the following:

export const options = {
  ext: {
    loadimpact: {
      projectID: <YOUR_PROJECT_ID>,
      // Test runs with the same name groups test runs together
      name: 'Default'
    }
  }
}

Run the k6 load test on Grafana Cloud

cd ./js/ssr
k6 cloud loadTest.js

Increase vus (Parallel virtual users) with another run:

k6 cloud --vus 10 --duration 30s loadTest.js
