✍️ Example

HTTP POST

Here is a simple example of a post request.

type: api
protocol: http
url: http://localhost:8080
method: post
format: json
body: 
  username: mehrdad
  password: 123456

In the following gif, you can see the way of using this sample.

Environment

Here I created an env varibale named url and used it in the previous example. This time I used UI to update yaml file. The url can has two value (localhost:8080 and google.com, labled as local and product), that helps to switch url easily. As you can see in the following gif, the url will be changed in the tests by changing it in environment panel.
