# 2025-08

| UAT release    | Production release |
| -------------- | ------------------ |
| 18 August 2025 | 01 September 2025  |

This month we have released some meaningful enhancements across different areas of the platform.

## Feature Focus: Testing Center — Systematic Test Case Generation <a href="#feature-focus-testing-center-systematic-test-case-generation" id="feature-focus-testing-center-systematic-test-case-generation"></a>

### Single Change Permutation Mode <a href="#single-change-permutation-mode" id="single-change-permutation-mode"></a>

The Systematic test case generation feature in Spark enables users to create test cases that cover test cases across all your input parameters. In this release, we’ve introduced a new **Single Change Permutation** mode to enhance the flexibility of test case generation. Unlike the original combination system — which creates all possible permutations of input values — this mode generates test cases where **only one variable changes at a time**, keeping all others constant.

### Benefits <a href="#benefits" id="benefits"></a>

* Enables more controlled, isolated testing.
* Allows for **wide coverage** of input variations.
* Keeps the **number of test cases low**, reducing redundancy and execution time.
* Useful for pinpointing the impact of individual variables.

### How It Works <a href="#how-it-works" id="how-it-works"></a>

To use the Single Change Permutation mode, start by selecting it in the “Define your testbed” section. Once selected, you’ll add and configure your input fields and values—just like you would in the original All Permutations mode. The system then uses your default values as the baseline and generates new test cases by changing one value at a time across your selected inputs. This results in a clean, easy-to-compare set of test cases that provides wide coverage while keeping the number of variations low.

If you have dismissed the notification by accident and would like to review the release messages again, you can click the User menu and choose *What’s new*.

## Notable enhancements <a href="#notable-enhancements" id="notable-enhancements"></a>

* **Testing Center**: The *Run Testbed* journey has UX improvements for more consistent terminology and clearer indicators of successful or failed testbed runs.
* **API Tester**: The *Raw* view now includes a **Copy** button to make it easier to copy and edit API requests and responses.
* **Import and Export API**:
  * A new `/status` endpoint allows you to check job progress.
  * Export API is now significantly faster for services with many versions.
  * Export API provides more detailed timing information for service exports.
* **API Call History**: A new endpoint allows access to individual call details using the `call_id` reference.
* **Multi-Factor Authentication**: MFA for user accounts can now be enabled through the user management interface.
