Smarter testing starts here

The API Testing Lab in ATA is a complete platform for building, validating, and managing APIs. Test individual endpoints, chain multiple APIs into workflows, or simulate real backend behavior using mock servers; we have got you covered. Our form view helps with easier input configuration, Ui automation testing automates flows, robustness testing tests against edge cases, to performance monitoring and chained API executions. ATA gives you everything you need to test smarter and faster in a single platform.

Quick validation

ATA comes with a form view and schema generation to simplify testing for cross-functional teams. Test multiple API scenarios, use test scripts, and validate responses, collaborating in one workspace.

Mock Scenarios

Create REST and SOAP mock servers with multiple request-response scenarios. Use existing API collections or let AI generate mock requests to simulate backend behavior during early development.

Share Collections

ATA allows you to share API collections across individuals or companies, making collaboration easy and eliminating the need to export collections every time you share.

Testing Automation

ATA goes beyond API testing by assessing API robustness and security risks. Its UI testing captures user interactions to auto-generate test cases and code, refining your workflow.

Go beyond the basics

Let’s explore the full range of tools built into ATA API Testing Lab

API Collections

  • Ad-hoc Testing: Instantly run and manage API requests inside your collections with full control over configuration and execution.
  • Collection Dashboard: Get a clear overview of your API collections. Track top and slowest APIs, view performance metrics, and access individual reports for better decision-making.
  • Forms & Schema Generation: Manage API requests using a form layout and auto-generated request schemas to ensure consistency across the team.
  • Test Scripts: Validate API responses, apply custom logic, and run dynamic tests with ATA’s built-in scripting support.
  • API Examples: Save and reuse real request-response pairs to simulate scenarios, debug faster, and document.
  • Environment Variables: Use dynamic, reusable values in requests to easily switch between environments like dev, staging, and production.
  • API Call History: Track every request made, along with its payload and response — ideal for debugging and audit trails.
  • Export/Import: Move API collections between workspaces or users without losing structure, configuration, or data.
  • Shared Collections: Share your collections across teams, individuals, or entire companies — and receive shared collections just as easily.

API Monitoring

  • Instant & Scheduled Runs: Run API monitors or schedule them to execute automatically — perfect for keeping tabs on critical endpoints around the clock.
  • Monitor Existing APIs: Create monitors directly from your existing API collections, saving setup time and ensuring test coverage is always up to date.
  • Notification Configuration: Configure retries and get notified via email or third-party tools like Slack and Microsoft Teams when tests fail or responses change.
  • Test Scripts: Validate monitoring results based on test scripts written for each API, providing accurate pass/fail reports based on your validation logic.
  • Execution Reports: See detailed execution data for every run, including response status, execution time, and script-level pass/fail results.
  • Monitoring Dashboard: Track the overall monitor health in one place. View total runs, success and failure rate, average response times, and status over different periods.
  • Execution Graphs: Visualize each monitoring run with detailed graphs that highlight individual test outcomes and long-term trends.

Mock Servers

  • Support for REST & SOAP: Create mock servers for both REST and SOAP APIs to replicate real backend behavior during development.
  • AI-Generated Mock: Ask our AI assistant to generate mock requests. Include the necessary details, and it will work exactly how you want it!
  • Mock Scenarios: Build multiple request-response scenarios under a single mock server to simulate different use cases or edge cases.
  • Table & Form View: Choose between Form View, Table View, or JSON View to create and manage mocks with better visibility and control.
  • Create from Scratch or Collections: Start fresh or generate mocks directly from your existing API collections, reducing duplication and speeding up setup.
  • Frontend-Ready Mocking: Use mock servers to unblock frontend development when backend services are still in progress or unavailable.

API Chain Testing

  • Workflow Automation: Chain multiple API requests with conditionals, delays, and wait steps to create real-life workflows that mirror user journeys.
  • API Configuration: Easily configure each API within the chain — set request parameters, headers, and body for complete control.
  • Reusable Variables: Pass data between chained APIs using variables to simulate dynamic, real-time interactions.
  • Workflow Testing: Validate the entire chain in one go — test how APIs interact together and ensure logic flows as expected.
  • Real-Time Execution: Run workflows instantly and observe live outputs to debug or verify behavior.
  • Notifications & Integrations: Receive workflow results via email or third-party tools like Slack and Microsoft Teams for timely updates.

UI Automation Testing

  • UI Interaction Tracking: Capture every user action automatically — clicks, inputs, hovers — as you manually test the UI step by step.
  • Smart Selector Detection: Automatically detects and generates selectors like XPath and CSS paths for each element interaction.
  • Customizable Selectors: Choose or delete generated selectors to fine-tune accuracy based on your test strategy.
  • AI-Generated Test Steps: ATA uses the captured interactions to generate detailed test steps automatically — no manual scripting required.
  • Generate Test Code: Convert test steps into ready-to-use automation code in your preferred testing framework (e.g., Cypress, Selenium).
  • Framework Flexibility: Export test code tailored to your stack, so you can plug it directly into your existing automation pipeline.

Robustness Testing

  • AI-Driven Test Generation: Generate test cases from human instructions using AI — no manual scripting needed.
  • Detect Edge Case & Malformed Input: Automatically test for path traversal, malformed payloads, mixed scripts, special characters, and JSON-breaking inputs.
  • Flexible Setup & Integration: Create test suites from scratch or import APIs from ATA, Postman, or Swagger — all within a few clicks.
  • Dynamic Data & Instruction Control: Use AI to generate data patterns and test logic, with the flexibility to edit, refine, or delete test cases as needed.
  • Safe Testing with Request Isolation: Run tests without modifying original API configurations — isolate behavior, debug safely.
  • Test Execution & Reporting: Execute tests individually or in bulk with real-time previews, pass/fail reports, and execution summaries.

Security Testing

  • Automated Security Scans: Run pre-built tests for injections, broken access controls, insecure headers, and more.
  • Easy Suite Setup: Create security test suites using APIs from ATA, imported collections, or connected applications.
