Example

A complete, runnable Java + JUnit 5 example.

@ExtendWith(TestersAIExtension.class)
class CheckoutTest {

    @Test
    void checkout(TestersAIFacade ta) throws Exception {
        // ...your Selenium / Playwright code...
        ta.screenshot(Files.readAllBytes(Paths.get("cart.png")),
                      Map.of("stage", "cart"));
        ta.screenshot(Files.readAllBytes(Paths.get("success.png")),
                      Map.of("stage", "success"));
    }
}

How it flows

🧪

Your test runs

JUnit 5 — unchanged.

📸

SDK captures

Screenshot, console, network, or page text.

🤖

Testers.AI analyses

Returns AI-identified issues.

📝

JUnit 5 report

Findings shown where you already look.

🔗

Optional: auto-log

Jira · Xray · TestRail · Cypress Cloud.

JUnit 5 ExtensionContext.publishReportEntry() — shows up in standard JUnit reports. If the AI call fails — rate limit, hang, firewall, no network — the SDK gives up fast and returns a skipped result. Your JUnit 5 test is never blocked.

Where & when to put checks

Rule of thumb: wherever a human reviewer would pause to look during a manual run. These recommendations are tuned for JUnit 5 — pick the ones that fit your suite.

After every meaningful navigation

The page just re-rendered. Ask "does this look right?" before any interaction.

after page.goto() / driver.get()

After a state-changing action

after click / fill

Right before your main assertion

You were about to check one thing. Ask the AI about everything else for free.

before expect(...)

After async operations settle

API returned, spinner gone, toast shown. Catch broken empty-states and stale data.

after wait_for_selector

In teardown / afterEach

A single console + network check at the end of every test catches issues your assertions ignored.

afterEach / teardown

On responsive / theme switch

Mobile vs. desktop, light vs. dark, locale change. One call per viewport.

after setViewport

Value: what you get for three extra lines

✓
Free upgrade to your existing JUnit 5 code.
No rewrites, no new dashboard, no new runner — reuse every selector, fixture, and helper you already built.
✓
Findings land in the JUnit 5 report.
JUnit 5 ExtensionContext.publishReportEntry() — shows up in standard JUnit reports.
✓
Optional TMS integration.
Set a few env vars and qualifying findings auto-log to Jira / Xray / TestRail / Cypress Cloud. Broken TMS never fails your test.
✓
Never blocks the suite.
Capped retries, hard deadline, graceful skip under load. Verified against mock hang/reset/429/403/DNS-failure.
