Test Companion

Agentic AI for test automation

Unlock 4x productivity with AI that accelerates your testing cycles.

Test Companion helps SDETs author, execute, debug, and maintain tests 4X faster with agentic AI right inside the IDE they already use.

Generate & maintain test cases from requirements, automate across UI, API, Accessibility, visual and more types of tests. Autonomously debug failures. Powered by an agentic harness connected to your existing automation framework & toolchain.

Backed by 30,000+ real devices on the BrowserStack cloud, so every test script is authored against actual app behaviour.

Key Features

• Generate Test Cases: Creates detailed scenarios with steps, expected results, and priority levels from PRDs, specifications, user stories, or by exploring a live URL or mobile app. For mobile apps, upload an APK, AAB, XAPK, or IPA file and let the AI explore your app on BrowserStack's real device cloud.
• Write Automation Scripts: Produces code for any testing framework in your project, including Playwright, Cypress, WebdriverIO, Selenium, Appium, Robot, Cucumber, and others. Convert existing manual test cases into code, or describe a new test from scratch. Works for both web and mobile applications.
• Debug & Fix Failing Tests: Connects to BrowserStack Test Reporting & Analytics or accepts pasted error logs. Identifies the root cause and suggests code-level fixes. You can also start this workflow from the Failure Analysis panel in the Automate dashboard.
• Find & Fix Accessibility Violations: Scans your web application against WCAG standards to identify accessibility issues. Applies automated code remediation directly to your source files.
• Test Mobile Apps on Real Devices: Uploads an APK, AAB, or IPA file and explores your app on BrowserStack's device cloud. Generates test cases and automation scripts based on its findings.
• Validate Code Changes (Dev Testing): A shift-left workflow that understands your local codebase and generates tests specific to what you are currently building, before the code reaches QA.
