PromptTest: The Zero-Code Autonomous Mobile QA Brain for Android & iOS (Appium & Detox Alternative)

shriram Singh — Fri, 02 Oct 2026 05:56:37 +0000

Traditional mobile automation frameworks like Appium and Detox are notoriously brittle. Flaky locators, heavy WebDriver dependencies, complex device farm setups, and constantly broken test suites slow engineering velocity to a crawl.

PromptTest (https://shriramsingh.github.io/prompttest-studio-site/) was engineered to solve this: a high-speed, local-first mobile QA and visual regression testing brain that lets you author and run tests in plain human English without writing a single line of boilerplate code.

⚡ What Makes PromptTest Different?

Plain-English Test Authoring: Write test suites in plain English (e.g., Tap "Get Started", Assert text "Welcome Back" is visible, Swipe down to "Order History").
Autonomous State-Graph Exploration: PromptTest crawls your native view hierarchies, builds an internal navigation graph, and automatically tests application flows hands-free.
High-Speed ADB RAM Streaming: Bypasses sluggish WebDriver middleware. Captures screen buffers and accessibility nodes directly over local ADB in milliseconds.
Visual Regression with Exclude Masks: Compare UI states with pixel-level precision. Drag dynamic exclude masks over timestamps, carousels, or random banners.
100% Local-First & Air-Gapped: Runs entirely on your local workstation without forcing your test data into external third-party clouds.

🚀 Quick Start

Run Headless via NPM Install globally or run directly in your CI/CD release pipelines:

npx prompttest run specs/checkout_flow.txt

Or install globally:
npm install -g prompttest

Autonomous App Crawl Let PromptTest explore your mobile app autonomously:

prompttest explore --safety-mode=strict

Visual Desktop IDE (PromptTest Studio) If you prefer a rich visual workspace with interactive device mirroring, 1-click element inspection, and test recording, check out the standalone desktop application:

Introducing ADBSnap: Automated Android Screenshot & 4K Store Mockup Tool (CLI & VS Code)

shriram Singh — Fri, 02 Oct 2026 05:07:20 +0000

If you develop mobile apps for Android, Flutter, or React Native, you know the pain: taking screenshots, transferring them to your desktop, dropping them into Figma or Photoshop templates, tweaking bezels, and re-exporting multiple resolutions for Google Play and the App Store.

I built ADBSnap to automate this entire workflow down to a single second.

⚡ What is ADBSnap?

ADBSnap is an open-source tool available on NPM and the VS Code Marketplace that:

Streams live device frames into RAM: Captures directly from physical Android devices or emulators over ADB without leaving junk files on your device.
Wraps in 4K Vector Bezels: Composites pixel-crisp bezels (iPhone 16 Pro with Dynamic Island, Google Pixel 9 Pro, Android Tablets, or Frameless canvas).
Applies Studio Gradients & Auto-Typography: Renders marketing headlines, subtitles, and rating badges directly above the device.
1-Click App Store & Play Store Bundler: Exports all required screenshot dimensions into a ready-to-upload ZIP archive.
Wireless ADB Suite: 1-click toggle between USB and Wi-Fi debugging with Android 11+ pairing support.

🚀 Quick Start

1. Launch the Interactive Visual Studio

You can run it right now from any terminal without installing anything:


bash
npx adbsnap studio

It boots an ultra-fast visual studio (< 15ms startup) in dedicated frameless desktop app mode.

2. Install Globally via NPM

npm install -g adbsnap

Then capture and frame your active screen with a single command:
adbsnap snap --title="Track Daily Habits" --theme=sunset --device=pixel-9-pro

3. VS Code Extension

If you prefer staying inside your editor, install the official extension directly from the Marketplace:

Search for adbsnap in the VS Code Extensions tab, or
Run code --install-extension shriramsingh.adbsnap

You can snap live screens and paste formatted mockups directly into your PR descriptions, release notes, or Markdown docs.
