Test Builder

Visual, no-code interface for creating HTTP-based load tests. Compose requests using forms and dropdowns—the UI automatically generates executable k6 scripts.

Building Tests​

Request Groups​

Organize related requests into logical groups (e.g., "User Authentication", "Product Search").

Test Builder Group
  1. Click Add Group
  2. Enter group name
  3. Add requests within the group

HTTP Requests​

Configure requests using the visual interface.

Test Builder Request Scenario

Configuration options:

  • Method (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS)
  • URL (supports variable substitution)
  • Headers and query parameters
  • Request body (JSON, form-data, raw text)

Sleep Statements​

Add delays between requests to simulate realistic user behavior.

Test Builder Sleep

Click Add Sleep and specify duration in seconds.

Global Variables​

Define reusable variables for URLs, authentication tokens, and test data.

Test Builder Global Variables

Reference variables using ${VARIABLE_NAME} syntax:

URL: ${BASE_URL}/api/users/${USER_ID}
Header: Authorization: Bearer ${AUTH_TOKEN}

Test Configuration​

Test Builder Options

Load settings:

  • Virtual Users (VUs) - Concurrent simulated users
  • Duration - Test runtime (e.g., "30s", "5m")
  • Ramp-up time - Gradual increase to target VUs

Thresholds:

http_req_duration: ['p(95)<500']  // 95% of requests under 500ms
http_req_failed: ['rate<0.01']    // Less than 1% error rate

Execution zones:

  • Single zone - All VUs from one location
  • Multi-zone - Distribute load across regions

AI-Powered Generation​

Generate requests using natural language.

Test Builder AI

Click the AI icon, describe the request (e.g., "Create a POST request to login with email and password"), and review the generated configuration.

Importing Tests​

Load existing configurations from files or URLs.

Test Builder Import
Test Builder Imports

Click Import and select source (file or URL).

Code View​

View the generated k6 script in the Code tab.

Test Builder View

Copy code or switch to Script Editor for manual editing.

warning

Complex script logic (loops, conditionals, custom functions) may not fully display in the visual interface.
