ZeuZ
Regression testing

Automated regression testing that stays green when the UI changes.

Automated regression testing in ZeuZ runs your web, mobile, desktop and API suites on every merge and repairs what the UI change broke as a diff your team approves. The suite you already have keeps running; the week you spend keeping it green goes away.

In one paragraph

Regression testing in software development is the re-running of existing tests after a code change to confirm that what worked before still works. ZeuZ automates it end to end: existing suites run on every merge or on a schedule across web, mobile, desktop and API, failures arrive grouped with evidence, and locator breaks come back as proposed repairs your team approves before merge.

The problem

Where regression suites break today.

Every UI change breaks selectors that were never wrong, and the suite goes red for reasons that have nothing to do with the release.

The suite runs when someone remembers, so the failure surfaces in staging on Thursday instead of on the merge that caused it.

Coverage is whatever was automated years ago. New flows get tested manually because nobody has the week to script them.

The six steps

How ZeuZ automates regression testing.

  1. 01Test designProposes which regression cases a change needs from the changed files and tickets, ranked by importance, so coverage follows the release rather than history.
  2. 02Test case creationA plain-English description of the flow becomes a structured case with reusable steps and stable IDs.
  3. 03Test automationCompiles to readable Python in a repository you own; web, mobile, desktop and API in one suite with no separate framework per surface.
  4. 04Test executionRuns the set on a schedule, on a CI webhook or manually, in parallel across your own nodes, on Chrome, Firefox, Edge and Safari.
  5. 05Reporting and analysisFailures arrive grouped, flaky separated from real, with step status, error, screenshot and trace on one record.
  6. 06Test maintenanceWhen a locator breaks, ZeuZ proposes the repair as a diff; a person approves it. Nothing self-heals silently.

Your team reviews what ZeuZ produced. Nothing joins the suite or runs without a person accepting it.

What is covered

Regression testing tools that cover the whole application.

One suite covers web applications on Chrome, Firefox, Edge and Safari, native and hybrid iOS and Android apps, Windows and macOS desktop applications, REST, SOAP and GraphQL APIs, and database state in PostgreSQL, MySQL, MariaDB, SQL Server, SQLite and MongoDB. Runs start manually, on a schedule or from an authenticated CI webhook, and every run returns to the same set, branch, history and report.

Image-based and OCR checks cover the parts of a screen that have no DOM. That is as close to visual regression as ZeuZ claims: it checks that what should be on screen is there; it does not pixel-diff whole pages. Tests are versioned with the release branch, so an automated regression testing run for release/2026.09 tests release/2026.09.
