Taiko
Taiko is a browser automation framework and web end-to-end testing library used to perform programmatic user actions and verify application behavior. It functions as a headless browser testing tool capable of simulating real interactions and asserting page states in Chromium and Firefox.
The project includes a browser interaction recorder that captures live actions and exports them as executable JavaScript automation scripts. It also serves as a web accessibility auditor, analyzing pages to detect accessibility violations and ensure compliance with inclusive design standards.
The framework covers a wide range of capabilities, including element interaction and state verification, hardware and network emulation, and file upload and download management. It provides tools for network traffic interception, session video recording, and performance measurement, as well as support for testing on Android browsers.
The tool integrates with external test runners and provides static type definitions for development.
Features
- Browser Automation - Provides a comprehensive framework for simulating user interactions in web browsers to verify frontend behavior.
- Element Interaction - Simulates programmatic user actions including clicking, typing, dragging, and scrolling to test interfaces.
- Browser Automation Frameworks - Provides a comprehensive programmatic interface for controlling web browsers to automate user interactions and verify application behavior.
- DOM State Verification - Verifies that page conditions and DOM element properties match expected values to validate application behavior.
- Interaction Recording - Includes a browser interaction recorder that captures live actions and exports them as executable JavaScript scripts.
- Element Visibility Synchronization - Ensures target elements are visible and interactable by blocking execution until they appear on the page.
- Browser Driver Abstractions - Offers a unified API abstraction layer to control multiple browser engines including Chromium and Firefox.
- Headless Browser Testing Frameworks - Enables the execution of automated test scripts in Chromium and Firefox without a visible user interface.
- End-to-End Testing - Provides a library for validating complete user flows by simulating real interactions and asserting page states.
- DOM Element Selectors - Identifies DOM elements using CSS selectors, XPath, and proximity-based visual matching logic.
- Element Locators - Locates UI components using text, images, accessibility roles, and spatial relationships.
- Headless Browsers - Operates browser instances in headless mode by default to optimize execution speed in CI environments.
- Chrome DevTools Protocols - Utilizes the Chrome DevTools Protocol to programmatically control browser instances and automate interactions.
- Interaction Script Generators - Ships a recorder that captures live browser actions and exports them as executable JavaScript automation scripts.
- Browser Storage Managers - Provides capabilities to manipulate and verify data within browser local and session storage.
- Browser Context Injections - Injects custom JavaScript functions into the browser's global window object to manipulate application state.
- Automatic Execution Snapshots - Automatically captures screenshots of the browser state after every action to document the execution flow.
- Network Interception Tools - Intercepts and modifies network requests and responses at the browser protocol layer for server simulation.
- Traffic Interception Tools - Provides utilities for redirecting and stubbing network requests to simulate backend server responses.
- DOM Presence Polling - Determines if a specific element exists on the page by polling for its presence over a defined timeout.
- Accessibility Auditing - Analyzes web pages for accessibility violations to ensure compliance with inclusive design standards.
- Mobile Browser Automation - Runs automation scripts on Android devices and emulators to verify behavior on mobile browsers.
- Bulk Element Operations - Identifies and manipulates multiple matching elements to perform bulk actions or verify collections.
- Automation Session Recording - Captures video recordings or GIFs of script execution for visual debugging and auditing.
- Device and Network Emulators - Simulates specific hardware viewports and network connection speeds for cross-environment performance testing.
- Browser File Transfers - Handles uploading files from the local system to web forms and downloading files to specified directories.
- Page State Analysis - Inspects and interprets the current DOM and browser environment to ensure specific conditions are met.
- Page State Captures - Retrieves screenshots, URLs, and page titles to document and verify the application's navigational state.
- Network Resilience Simulators - Emulates various connection speeds and offline states to measure application performance under network constraints.
- Accessibility Auditors - Analyzes web pages to detect accessibility violations and ensure compliance with inclusive design standards.
- Test Runner Integrations - Connects browser automation scripts to external test frameworks for execution management and result reporting.
- Browser File Management - Configures local directories to automatically capture and store files downloaded by the browser.
- Dynamic UI Synchronizers - Synchronizes test execution by waiting for network requests and element loading to complete.
- Context Data Exchange - Enables passing serializable arguments into the browser context and retrieving values from the page.
- JavaScript Execution Bridges - Allows running custom JavaScript directly within the browser context and retrieving results back to the test runner.
- Window Object Mocking - Allows defining or overriding JavaScript functions on the window object to mock behavior or invoke application methods.
- Element Wait Conditions - Implements polling mechanisms that pause execution until specific elements become visible or present on the page.
- Browser Dialog and Event Handlers - Handles native browser UI events such as alerts, prompts, and confirmation dialogs.
- Browser Session Managers - Manages browser windows, tabs, and incognito modes to simulate distinct user sessions.
- Full Page Screenshots - Captures images of the visible viewport or entire scrollable pages for visual verification.
- Automation Libraries - Node.js library for browser automation.
- Test Runners - Simplified Node.js API for Chromium automation.
- Frameworks de pruebas - A Node.js library with a simple API to automate Chromium based browsers.
