Test with K6

BIC E2E and Performance test.

Installation

1. Install dependencies

yarn

2. Set environment variables

$ cp .example.env .env

# open .env and modify the environment variables (if needed)

Running the Test using Makefile

1. Build k6 with extensions

make build-extension

2. Run test with parameters

make run extensions="dashboard,elasticsearch" report="dashboard/report.html"

Recognized parameters:

• extensions: K6 extensions for output (separate by ,, options: dashboard, elasticsearch).
• report: File name for exporting the report (used if dashboard extension is included).

If using elasticsearch metrics are stored in the index k6-metrics, which is automatically created by the xk6-output-elasticsearch extension.

Running the Test manual

1. Build script test

yarn build

2. Build k6 with extensions

For Linux

docker run --rm -it -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" grafana/xk6 build v0.43.1 --with github.com/oleiade/xk6-kv --with github.com/grafana/[email protected] --with github.com/Juandavi1/[email protected] --with github.com/gpiechnik2/[email protected] --with github.com/elastic/[email protected]

For MacOS

docker run --rm -it -e GOOS=darwin -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" grafana/xk6 build v0.43.1 --with github.com/oleiade/xk6-kv --with github.com/grafana/[email protected] --with github.com/Juandavi1/[email protected] --with github.com/gpiechnik2/[email protected] --with github.com/elastic/[email protected]

For Windows

docker run --rm -it -e GOOS=windows -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" grafana/xk6 build v0.43.1 --output k6.exe --with github.com/oleiade/xk6-kv --with github.com/grafana/[email protected] --with github.com/Juandavi1/[email protected] --with github.com/gpiechnik2/[email protected] --with github.com/elastic/[email protected]

3. Run the test

./k6 run --out dashboard=report=dashboard/report.html dist/main.test.js

Run with output elasticsearch. The metrics are stored in the index k6-metrics which will be automatically created by extension xk6-output-elasticsearch

export K6_ELASTICSEARCH_URL=xxx
export K6_ELASTICSEARCH_USER=xxx
export K6_ELASTICSEARCH_PASSWORD=xxx

./k6 run --out dashboard=report=dashboard/report.html --out output-elasticsearch dist/main.test.js

Output Results

HTTP Aggregation (httpagg)

• By default, the httpagg report is exported to dashboard/httpagg-report.html.

Dashboard

• By default, the dashboard report is exported to dashboard/report.html.

• If the report parameter is provided when running the test, the report is exported to the specified path.

Elasticsearch

• Metrics are stored in the index k6-metrics, automatically created by the xk6-output-elasticsearch extension.

Writing own tests

House rules for writing tests:

• The test code is located in src folder
• The entry points for the tests need to have "test" word in the name to distinguish them from auxiliary files. You can change the entry here.
• If static files are required then add them to ./assets folder. Its content gets copied to the destination folder (dist) along with compiled scripts.

Steps to run the seed data

1. Change config

• Update config in config.ts if you need.
• Update communityIndex in scripts/main.script.ts to change the community for create contents.

2. Run the seed

yarn create-data

Transpiling and Bundling

By default, k6 can only run ES5.1 JavaScript code. To use TypeScript, we have to set up a bundler that converts TypeScript to JavaScript code.

This project uses Babel and Webpack to bundle the different files - using the configuration of the webpack.config.js file.
