What is WireMock?

WireMock 4.0 beta.42 can record every request header, still in beta.

WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. After a quiet month, beta.42 and beta.43 arrived on November 12 and 13: recording can now capture all request headers with exclusions, a new extension point lets code react to served messages, and the rest is Dependabot bumps.

What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

WireMock vs CircleCI: editorial side-by-side

W
WireMock
INFRA · APIS
5.0

WireMock 4.0 beta.42 can record every request header, still in beta.

◆ Current state

WireMock is the standard Java tool for mocking HTTP APIs, and its 4.0 line is still in beta. After a quiet month, beta.42 and beta.43 arrived on November 12 and 13: recording can now capture all request headers with exclusions, a new extension point lets code react to served messages, and the rest is Dependabot bumps.

◆ Where it's heading

The 4.0 betas are still mostly fixes and dependency updates, with small additions to recording and message channels. Nothing signals a final release yet.

◆ Prediction

Expect more numbered betas with recording and message-channel fixes; when 4.0 goes final is not visible from these entries.

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
