BrowserStack launches Test Companion, agentic AI for test automation in the IDE

DUBLIN, July 29, 2026 /PRNewswire/ — BrowserStack, the leading AI-native software testing platform, today announced Test Companion, an agentic AI solution for test automation integrated directly into the IDE. Designed for QA teams and automation engineers, it accelerates test authoring, execution, debugging, and maintenance across web and mobile applications.

Closing the Testing Gap

AI coding agents have significantly accelerated software writing, but this speed has not translated into faster releases. A 2026 NBER study found that AI coding agents increased commits by 180%, while releases rose by just 30%. Testing is a key factor in this gap: coding agents like GitHub Copilot, Cursor, and Claude Code can generate test code, but they are not purpose-built for the context, infrastructure, and workflows required across the testing lifecycle.

Test Companion addresses this gap with a testing harness embedded in the IDE, working with a team's existing code, frameworks, and testing stack from day one — with no setup or context switching.

Key Capabilities

• Complete test cycle in the IDE: Generates test cases, authors and executes scripts, debugs failures, and works directly with browsers and devices across functional, visual, accessibility, and API testing.
• Grounded in real code and devices: Understands existing automation frameworks — page objects, helpers, and conventions — and validates on 30,000+ real devices and browsers.
• Built for specialised testing workflows: Uses custom skills and sub-agents for root-cause analysis, test healing, and visual testing, with dedicated prompts, tools, and orchestration for each.
• Integrates with tools teams already use: Adapts to Playwright, Selenium, Cypress, Appium, WebdriverIO, and TestNG, and integrates with Jira, test management, and reporting out of the box.
• Built for enterprise-wide standardisation: Provides QA teams with a consistent testing harness featuring shared models, guardrails, governance, and traceability, helping regulated teams maintain oversight of test coverage and agent actions.

Executive Insight

"Fifteen years of building for testing teams taught us that a test is never written and done. The application changes, the test breaks, and someone has to fix it. Any AI that only writes tests solves the easy part. Test Companion owns the full cycle, and that's the shift." — Nakul Aggarwal, CTO and co-founder of BrowserStack

Part of BrowserStack's AI Portfolio

Test Companion is the newest addition to BrowserStack's AI portfolio. In 2025, the company launched BrowserStack AI, a suite of 20+ agents built across the testing lifecycle, followed by the open-source BrowserStack MCP Server, which connects its testing platform to AI tools like GitHub Copilot, Cursor, and Claude. Test Companion extends that intelligence into the IDE, bringing agentic testing directly into existing workflows.

Availability

More than 1,000 teams already use Test Companion to author, debug, and maintain tests up to 4x faster. It is available now and installs from the marketplace in VS Code, JetBrains, Cursor, and Antigravity.
