✍️ Example
Here is the most simple test file you can have.
type: api
title: GET sample
tags:
- regression
- smoke
interfaces:
- name: GET Foo Bar
protocol: http
format: json
url: http://localhost:8080
method: get
Here you can see the screen shot of using this sample. On the right side, beside a UI for modifying the test yaml file interactively, you can have some smoke tests.
