Web application testing

Automated web application testing on Chrome, Edge, Firefox and Safari.

Web application testing in ZeuZ turns a written description of a user flow into a readable test and runs it on Chrome, Edge, Firefox and Safari from your pipeline, with the screenshot and trace for every failed step. When the front end changes, the fix comes back as a diff your team approves before it joins the suite.

In one paragraph

Functional web application testing is the checking of a browser-based application's pages, forms, logins and user flows after a change, to confirm they still work for real users. ZeuZ automates it: a description written in everyday words becomes a readable test that runs on Chrome, Edge, Firefox and Safari from your pipeline, with evidence for every step.

The problem

Where automated web testing breaks today.

Selectors written against generated class names break on the next front-end release, and the suite goes red for reasons that have nothing to do with the change.

Writing a Playwright or Selenium test takes an engineer, so coverage grows only as fast as the one or two people who can script, and new flows get checked manually.

Logins, role permissions and shadow DOM components are where scripts fail first, and they are the flows a customer notices when they break.

The six steps

How ZeuZ automates web application testing.

  1. 01Test designProposes the flows a change needs tested from the changed files and tickets, ranked by impact, change risk, reach and coverage.
  2. 02Test case creationDescribe the flow in your own words; ZeuZ writes a structured case with reusable steps for login, navigation and checkout, each with a stable ID.
  3. 03Test automationThe case compiles to readable Python in a repository you own, on Playwright across Chromium, Firefox and WebKit, with Selenium WebDriver for classic ZeuZ web actions.
  4. 04Test executionRuns on a schedule, from a CI webhook or manually, in parallel across your own nodes.
  5. 05Reporting and analysisEvery failed step returns the error, screenshot and trace on one record, with flaky runs separated from real failures.
  6. 06Test maintenanceWhen a locator breaks, ZeuZ proposes the repair as a diff, and a person approves it before it joins the suite.

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

What is covered

Web application testing tools for real user flows.

ZeuZ runs web tests on Chrome, Firefox, Microsoft Edge and Safari, selected per run. Tests authored in Test Studio compile to readable Python on Playwright across Chromium, Firefox and WebKit and live in a repository you own; classic ZeuZ web actions run on Selenium WebDriver. Locators match attributes partially and case-insensitively, walk parent, sibling and index relationships and reach into shadow roots, and the AI Web Recorder generates them from the page. Where part of a screen has no DOM, such as a canvas or chart, image and OCR checks find it by what is on screen.

API calls, database assertions against PostgreSQL, MySQL, MariaDB, SQL Server, SQLite or MongoDB, and an axe-based WCAG scan can run as steps in the same case, which is what web application testing needs when a flow crosses the UI and the data behind it. Environment values are bound once and overridden at run time. Runs start manually, on a schedule or from an authenticated CI webhook, in parallel across your own nodes, and return to the same set, branch and history.
