Cross-Browser Testing

Cross-browser testing without building or babysitting a grid

Cross-browser testing shouldn't mean maintaining a pile of machines and drivers. Robonito runs the same journey across major browsers and screen sizes in built-in environments, so 'works on my machine' stops being the answer.

01The problem

It works in one browser. Your customer uses another.

Your team tests in the browser it uses every day. Your customers don't all use that one, or the same screen size.

01 / 03

Grid upkeep

Keeping browsers, drivers, and machines up to date becomes a part-time job that nobody signed up for.

02 / 03

Layout bugs on other screens

The pricing table looks fine on a laptop and overlaps on a smaller screen, and the first person to notice is a prospect.

03 / 03

Duplicate test effort

Running each journey by hand in every browser takes so long that most of them get skipped before release.

02Capabilities

Cross-browser testing that runs where you need it

Write the journey once. Robonito handles where it runs and tells you where it broke.

01

One test, many browsers

Run the same test case across major browsers without rewriting it, so coverage grows without growing your suite.

  • Major browsers
  • One test

02

Screen size coverage

Check journeys at different screen sizes, so responsive layouts are verified, not assumed.

  • Responsive
  • Screen sizes

03

Built-in environments

Pick an environment and run. There's no grid, driver, or browser install to maintain on your side.

  • Environments
  • No grid

04

Parallel execution

Run browser combinations in parallel, so a full compatibility pass fits inside your release window.

  • Parallel runs
  • Faster feedback

05

Visual verification

AI visual checks catch layout and rendering differences between browsers that a functional assertion would miss.

  • Visual
  • Layout

06

Self-healing and root cause

Tests adapt to UI changes, and when one browser fails, the agent explains what broke there and why.

  • Self-healing
  • Root cause

03How it works

How cross-browser testing works in Robonito

  1. 1

    Create the journey

    Describe it in plain language, record it with the browser extension, or reuse a test case you already have.

  2. 2

    Choose browsers and sizes

    Select the environments and screen sizes you want to cover. Robonito provides them, so there's nothing to set up.

  3. 3

    Compare results

    See which browsers passed and which failed, with step logs and root causes, in one report your team can act on.

04Use cases

Cross-browser testing scenarios that save releases

Pricing page on smaller screens

A marketing team runs its pricing and sign-up journey across browsers and screen sizes, and catches a plan card that covers the sign-up button on narrower screens.

Date picker in one browser

A booking app's date picker works everywhere except one browser. The cross-browser run flags it with a step log before the feature ships.

Customer portal after a CSS refactor

After a styling cleanup, a team reruns its portal journeys in every environment and confirms nothing shifted outside the intended changes.

05Proof in every run

See every browser's result in one place

Compatibility bugs are easy to argue about and hard to prove. Robonito gives you the proof.

Per-browser results

Pass and fail for each environment from the same run.

Proof you get: Run results for each environment

Step logs where it failed

See the exact step that broke in the browser that broke.

Proof you get: Step-by-step run log with screenshots

Visual differences

Layout and rendering issues are flagged, not just functional failures.

Proof you get: Visual verification result

07FAQ

Frequently asked questions

What is cross-browser testing?

Cross-browser testing checks that a website or web app works and looks right across different browsers and screen sizes. Browsers can render pages and run scripts differently, so a journey that works in one may break in another. Robonito automates cross-browser testing by running the same test across major browsers in built-in environments.

How do you do cross-browser testing without maintaining a grid?

You use a platform that provides the browser environments for you. With Robonito, you pick from built-in environments and run your journey across them, so there are no machines, drivers, or browser installs to maintain. Your team writes the test once in plain language, and Robonito handles where it runs.

Which browsers does Robonito support?

Robonito runs tests across major browsers and multiple screen sizes through its built-in environments. The exact mix you need depends on your audience, so it's worth starting with the browsers your customers use most. Talk to our team or start free to see the environments available for your web app.

Is cross-browser testing the same as responsive testing?

Not quite: cross-browser testing checks behavior across different browsers, while responsive testing checks layouts across screen sizes. Most teams need both, because a layout can break in one browser at one size. Robonito covers both by running the same journey across major browsers and screen sizes, with visual checks for layout issues.

How do I keep cross-browser tests from breaking every release?

Use tests that self-heal. Robonito's agents adapt when buttons, labels, or layouts change, so your cross-browser suite doesn't fail for cosmetic reasons. When a failure is real, the agent reports the root cause and the browser it happened in, so your team can fix the product instead of fixing the test.
