First install k6 in your system. We will go for Linux (Ubuntu).

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61
echo "deb https://dl.bintray.com/loadimpact/deb stable main" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install k6

Open any IDE for writing test code. We will use WebStorm. To enable code suggestion for k6, install this library with npm:

$ npm init --yes
# install the k6 types as dev dependency
$ npm install --save-dev @types/k6

For showing visual chart while the test is running, we have some of the methods:

• Amazon CloudWatch
• Apache Kafka
• InfluxDB + Grafana
• Cloud
• CSV
• Data Dog

We will use InfluxDB and Grafana for visualization.

Install InfluxDB with Docker

docker run -p 8086:8086 \
      -v $PWD:/var/lib/influxdb \
      influxdb

Install Grafana as service in Ubuntu

sudo apt-get install -y adduser libfontconfig1
wget…
