What is Chromatic?

Chromatic opens a beta that lets coding agents read and fix visual test failures.

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

What is Microcks?

Microcks 1.16 candidate adds IBM MQ mocking and moves to hardened images with faster startup

Microcks 1.16.0-rc1 is the first release candidate since June's 1.15.0-rc1. It adds AsyncAPI mocking and testing for IBM MQ, request/reply handling for Google Pub/Sub with Workload Identity auth, TLS on the HTTP endpoint and external references in the OpenAPI-to-MCP tool converter. The container images switch to Docker Hardened Images by default and replace Spring AOT with a Leyden AOT cache to cut startup time.

Chromatic opens a beta that lets coding agents read and fix visual test failures.

◆ Current state

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

◆ Where it's heading

Chromatic is turning from a review screen for humans into a feedback loop that coding agents can act on. Each new entry point (Vitest, React Native, now agents) widens who and what sends work through its visual tests.

◆ Prediction

The beta post is brief, so how agents connect is unclear; expect a follow-up naming the supported agents and moving this toward general availability.

Microcks 1.16 candidate adds IBM MQ mocking and moves to hardened images with faster startup

◆ Current state

Microcks 1.16.0-rc1 is the first release candidate since June's 1.15.0-rc1. It adds AsyncAPI mocking and testing for IBM MQ, request/reply handling for Google Pub/Sub with Workload Identity auth, TLS on the HTTP endpoint and external references in the OpenAPI-to-MCP tool converter. The container images switch to Docker Hardened Images by default and replace Spring AOT with a Leyden AOT cache to cut startup time.

◆ Where it's heading

The project keeps broadening the messaging systems it can mock, now reaching enterprise brokers like IBM MQ and Amazon MQ over TLS. In parallel it is reworking its runtime for faster cold starts and smaller attack surface, and the MCP tool converter shows it treating API specs as inputs for AI agents as well as tests.

◆ Prediction

Further 1.16 candidates are likely to fix AOT and hardened-image edge cases, since this candidate already carries several JVM crash and probe fixes tied to that switch.
