20 Web App Testing alternatives
Web App Testing: Interact with and test local web applications using Playwright — verify frontend behavior, debug UI, capture screenshots, and read browser logs. 20 agent skills do similar work, most sharing Testing, Debugging and Browser Automation, ranked by how much they have in common with Web App Testing.
-
by Microsoft
Microsoft's official Playwright skill — drives a real browser from the command line using accessibility snapshots and element refs, and plans, generates and heals Playwright tests.
Also: Browser Automation, Debugging, Testing
-
by TestMu AI
TestMu AI's official skill for generating production-grade Playwright suites in TypeScript, JavaScript, Python, Java or C#, locally or on a 3,000-combination browser cloud.
Also: Browser Automation, Testing
-
by PostHog
PostHog's official skill for auditing a live analytics implementation — scripts, network calls, and window state — read-only, via browser automation.
Also: Browser Automation, Debugging
-
by Jesse Vincent
A disciplined debugging process — reproduce, isolate, hypothesise, and verify — used before proposing any fix.
-
by Datadog
Official Datadog skill for investigating one flaky test — pulls its history and failure pattern, categorises the root cause and recommends fixing, quarantining or escalating.
-
by Datadog
Official Datadog skill that triages a failing PR pipeline, attributing every CI failure as flaky, infra or genuine regression and proposing a targeted fix.
-
by Browserbase
Browserbase's official skill for driving a real browser from an agent via the browse CLI - navigate, snapshot, fill forms and click, locally or in a cloud session.
Also: Browser Automation
-
by Jesse Vincent
Never claim work is complete, fixed, or passing without running the check and reading the output first.
Also: Testing
-
by Jesse Vincent
Enforce a real red-green-refactor loop when implementing features or fixes, so behaviour is specified before it is written.
Also: Testing
-
by SerpApi
A protocol for measuring whether agents can discover and use your tool without being told about it — WITH/WITHOUT trials, binary scoring, and lift as the only metric. The subject under test is your docs, not the model.
Also: Testing
-
by Grafana Labs
Grafana's official k6 skill: generate a load, stress, spike or soak test from a plain-language brief, then actually run the script before handing it over.
Also: Testing
-
by arpitg1304
Ten SKILL.md modules that give coding agents real ROS engineering judgement — ROS 1 and ROS 2, design patterns, perception, testing, Docker, bringup and robot security.
Also: Testing
-
by Cypress.io
Cypress' official skill for writing, updating and repairing E2E and component tests — and it triggers on "write tests" even when nobody says Cypress.
Also: Testing
-
by Trail of Bits
Trail of Bits' skill for writing production-quality Semgrep rules — pattern design, taint mode for data-flow bugs, and mandatory test-driven validation.
Also: Testing
-
by NVIDIA
Diagnoses wrong gradients in differentiable NVIDIA Warp programs by measuring first — comparing autodiff against finite differences on a shrunk reproduction before proposing any fix.
Also: Debugging
-
by Microsoft
Microsoft's official plugin for building, editing, running and debugging Power Automate cloud flows, with a bundled offline FlowAgent MCP server.
Also: Debugging
-
by dbwls99706
A single progressive-disclosure skill for production ROS 2 work — rclcpp/rclpy, colcon, QoS and DDS, tf2/URDF, ros2_control, Nav2, MoveIt 2, plus ROS 1 migration and hardware safety gates.
Also: Debugging
-
by MongoDB
MongoDB's official skill for connection pools and timeouts — it refuses to hand you numbers until it knows your deployment, workload and concurrency.
Also: Debugging
-
by .NET Team at Microsoft
Diagnose an MSBuild build failure from a .binlog file — query the binary log through a dedicated MCP server instead of grepping console output, with a text-replay fallback.
Also: Debugging
-
by Flutter
The Flutter team's official skill for diagnosing and fixing constraint errors — RenderFlex overflows, unbounded viewports and misplaced ParentData widgets.
Also: Debugging
