Jenkins vs Vitest: at a glance
What is Jenkins?
Jenkins is shrinking its own war file and rebuilding its UI, one weekly release at a time
The weekly train is dominated by two long efforts: an incremental redesign of the experimental Manage Jenkins UI, and a deliberate campaign to unbundle plugins from jenkins.war. 2.577 drops bouncycastle, the Command Agent Launcher, JAXB, the SSH server and more, following 2.574's removal of JUnit, Mailer and the matrix plugins. Interleaved security releases ship with no detail beyond a one-line note.
What is Vitest?
Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.
Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.

Jenkins is shrinking its own war file and rebuilding its UI, one weekly release at a time
◆ Current state
The weekly train is dominated by two long efforts: an incremental redesign of the experimental Manage Jenkins UI, and a deliberate campaign to unbundle plugins from jenkins.war. 2.577 drops bouncycastle, the Command Agent Launcher, JAXB, the SSH server and more, following 2.574's removal of JUnit, Mailer and the matrix plugins. Interleaved security releases ship with no detail beyond a one-line note.
◆ Where it's heading
Two releases cutting 20 MB each signal that unbundling is sustained policy, not a one-off — the core is being reduced toward a minimal server with plugins as an explicit choice. The UI work is methodical and unglamorous: scrollable side panels, sticky build bars, standardised dialogs and command palettes. Neither effort is close to finished.
◆ Prediction
More bundled plugins will be pulled in coming releases, and the experimental Manage Jenkins UI should keep absorbing pages until it can drop the experimental label.
Vitest
5.0DEVOPS
Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.
◆ Current state
Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.
◆ Where it's heading
The through-line across beta.4 to rc.1 is consolidation of the runner's architecture — one config resolution path, one Vite server, one project tree that can nest — paired with defaults that surface mistakes instead of tolerating them (strict toHaveTextContent, hoistable-scope errors, unawaited assertions failing). The browser mode is being narrowed to a single first-party stack rather than a plugin matrix. Performance work is now targeted at memory retention in vm pools and large --changed graphs, which reads as pre-GA cleanup rather than new capability.
◆ Prediction
With breaking changes still landing in rc.1, expect at least one more RC to settle the nested-projects and shared-server behaviour before a v5.0.0 final.
