Test Data & Parameters

BlinqIO automatically extracts parameters from your test steps and provides tools to manage dynamic test data.

The Test Data panel

The Test Data panel is a collapsible section at the bottom of the left panel in the editor. It has two tabs:

Step Inputs tab

Displays all parameters extracted from your step names as editable key-value pairs.

How parameters work:

When AI generates a step name like:

When user enters "<username>" in the email field

The <username> token is automatically extracted and appears in the Step Inputs tab as an editable row:

Parameter	Value
username	admin
password	secret123

Editing parameter keys

Click a parameter name to rename it. Renaming updates all step names that reference it, and the matching parameters are highlighted.

Editing parameter values

Click a value to edit inline. Changing a value triggers a "run recommended" warning since the test needs re-validation.

Project Data tab

Displays a read-only JSON key-value viewer showing project-level settings:

• baseUrl: The application URL
• password: Stored credentials
• env: Environment settings
• apiToken: API access token
• timeout: Default timeout values

Each value has a copy-to-clipboard button.

AI Enhance

When AI Enhance is available for a parameter, the sparkle icon opens a modal that can suggest supported dynamic expressions instead of static values. You can also type these expressions directly without using AI Enhance.

Expression types

Type	Example	Use case
Faker	{{faker:internet.email}}	Generate realistic random data
JavaScript	${Math.floor(Math.random() * 1000)}	Compute numeric values dynamically
Date expressions	{{date:today + 7 days}}	Date arithmetic
Combinations	{{faker:helpers.fake("{{person.firstName}}.{{person.lastName}}@example.com")}}	Build a full string from multiple generators

How to use

1. Click the sparkle icon next to a parameter value
2. The AI Enhance modal opens showing the current value
3. Choose to:
   • Accept the AI-generated expression
   • Regenerate for a different suggestion
   • Custom prompt to describe what kind of value you need

Supported expressions include:

• {{faker:person.firstName}}
• {{faker:person.lastName}}
• {{faker:internet.email}}
• ${Math.floor(Math.random() * (65 - 55 + 1)) + 55}
• {{date:today + 7 days}}

Parameter highlighting

BlinqIO highlights matching parameters across your steps when you edit keys or values, making it easy to see how changes affect your test.
