Specmatic 2.44.0 Release Overview

Specmatic 2.44.0, a minor update in the Mobile and API Testing category, was released on 2026-04-20. This version focuses on refining conformance testing, overhauling coverage reporting, and strengthening SOAP API support.

Key Changes

Features & Improvements:

  • Conformance Testing: Expected conformance test failures now require an attached reason, enhancing clarity and traceability. This builds on previous adjustments to disable expected failures conformance.
  • Coverage Reporting: The coverage reporting mechanism has been significantly overhauled to provide more accurate and actionable insights into API test coverage.
  • SOAP API Testing: Enforces SOAP-version-specific Content-Type headers for both requests and responses, ensuring stricter protocol adherence and more reliable SOAP API validation.

Fixes & Maintenance:

  • Swagger Parser: Addressed critical thread safety bugs within the Swagger parser, improving stability.
  • Pattern Matching: Reverted a change related to min/max Items on ListPattern (Issue 1741), resolving a previous regression.
  • Security & Dependencies: Includes a security update for org.thymeleaf to v3.1.4.RELEASE and numerous other dependency updates across the project, ensuring better security and performance.

Impact for QA Teams

QA engineers will benefit from more reliable conformance checks, clearer and more accurate coverage metrics, and improved precision for SOAP API testing. These updates help identify issues earlier in the development cycle and maintain higher API quality standards across projects.
