API Integration E2E Tests: A Comprehensive Solution for Automated Integration Testing

The E2E Test Feature simplifies the creation and automation of end-to-end (E2E) tests for APIs. By uploading Postman collections (v2.1 format, via exported JSON or shared URLs) or Swagger definitions (in JSON, YAML, or URL formats), ratl automatically generates comprehensive test flows, simulating real-world scenarios to verify API sequences and manage dynamic properties.

After flows are generated, users can review, edit, and customize them to ensure they align with their requirements. Once finalized, ratl generates Java code to automate these tests, allowing for seamless execution as part of your CI/CD pipeline or on demand to ensure ongoing API reliability.

Key Benefits

• Automated Test Generation: Convert your API specifications (Postman or Swagger) into executable test flows with minimal effort.

• Real-World Scenario Simulation: Automatically generate test cases that reflect real API usage.

• Dynamic Property Mapping: Map and manage dynamic data between API calls to ensure accurate test execution.

• Code Generation: Generate Java code to integrate automated tests directly into your pipelines.

• Efficiency: Save time by automating complex test creation and maintenance.

• Increased Accuracy: Validate the sequence and data flow between APIs to catch errors early.

Pre-Conditions

• Ensure the API specifications (Postman collections v2.1 or Swagger definitions in JSON/YAML format) are ready for upload.

• Confirm that necessary API endpoints are documented and accessible.

• User must have sufficient credits.

How to Use the Integration Testing Feature

Step 1: Upload Your API Specification

1. Navigate to the E2E Test section within ratl.

2. Click the "Add Test Suite" button.

3. Upload your API specification:

   • Postman collections (file or URL, v2.1)

   • Swagger definitions (JSON, YAML, or URL)

4. Wait while ratl.ai parses the uploaded specification and generates end-to-end test flows.

---

Step 2: Review and Edit Flows

1. Select a generated flow to open it in the canvas view.

2. API blocks are displayed sequentially in the canvas.

3. Review the sequence to ensure it meets your testing requirements.

4. If any API is missing or needs to be added, click the "Add APIs" button to manually insert it into the flow.

---

Step 3: Map Dynamic Properties

1. Identify dynamic properties (such as tokens or IDs) that must pass between API calls.

2. Click on an "Edit Request" of corresponding api block to access its properties.

3. Use placeholders to map dynamic properties (e.g., $(login-user.response.data.id), where id is a nested property under data from the upstream login-user request) for downstream API requests.

4. Ensure these mappings are correctly applied across the flow.

5. Alternatively, use the input section to prompt ratl.ai to automatically map dynamic properties.

---

Step 4: Verify the Flow

1. Double-check that all dynamic properties are correctly mapped.

2. Ensure the API sequence reflects the desired test scenario.

---

Step 5: Generate Automation Code

1. Once the flow is verified, click the "Generate Code" button.

2. ratl generates Java code to automate the test flow.

3. Use the input section to prompt ratl for any code modifications as needed.

---

Step 6: Execute and Validate

1. Run the generated test to validate your APIs.

2. Monitor the results and re-run tests as needed.

3. Flows can be executed anytime to ensure continuous API validation.

4. Verify Test Report.

Post-Conditions

• Successfully generated Java code is available for integration into CI/CD pipelines.

• All dynamic properties are mapped, and test flows reflect real-world API interactions.

• Automated tests are ready to be executed and validated to ensure API reliability.
