Using Variables in API Testing

Variables allow you to make your API tests more dynamic and reusable by substituting placeholder values at runtime. This is particularly useful for managing environment-specific configurations (like base URLs) or data that changes between test runs.

Current Support: URL Variables

Currently, Robonito supports variable substitution directly within the API endpoint URL.

Syntax

To use a variable within the endpoint URL, enclose the variable name in double curly braces:

{{variable_name}}

Example

Imagine you have an environment variable named baseURL set to https://api.yourapp.com/v1. You can use this variable in your request URL like this:

{{baseURL}}/users/{{userId}}

During execution, Robonito will replace {{baseURL}} with https://api.yourapp.com/v1 and {{userId}} with the current value of the userId variable (assuming it's also defined).

(Note: Explain where variables like baseURL and userId are defined, e.g., in Environment settings.)

Upcoming Enhancements

We are actively working to expand variable support to other parts of the API request configuration:

• Request Body: Using variables within JSON payloads or form data.
• Authentication: Referencing variables for dynamic tokens or credentials.
• Headers: Using variables in request header values.

Stay tuned for future updates that will enhance the flexibility and power of your API tests in Robonito.
