Selenium vs Squish

Selenium is a free suite of tools for automating web browsers, primarily to test web applications. WebDriver provides language bindings for controlling browsers locally or remotely, and is a W3C Recommendation. The main project supports.NET/C#, Ruby, Java, Python, and JavaScript. Selenium IDE is a browser add-on for recording and replaying interactions in Chrome, Firefox, and Edge. For distributed tests, Selenium Grid spreads work across machines and combinations of browsers and operating systems. Grid offers Standalone, Hub and Node, and Distributed configurations; Docker and Kubernetes deployment resources are also linked. Selenium Manager can discover, download, and cache browser releases and drivers. Documentation covers browser-specific functionality for Chrome, Edge, Firefox, Internet Explorer, and Safari, and names GitHub Actions and Jenkins as CI/CD examples. Selenium began in 2004 at ThoughtWorks in Chicago. Grid has no authentication by default, and the project advises restricting external access and placing it behind a secure network. The latest Opera driver functionality is not supported, and that driver is officially unsupported. Selenium costs nothing.

Squish automates GUI tests for desktop, web, mobile, and embedded applications using object-based recognition and scripting. It locates interface elements by their properties rather than by image matching or DOM scraping; the product says this helps tests withstand UI changes. Tests can be authored in Python, JavaScript, Ruby, Perl, Tcl, or Behaviour-Driven Development. Listed application technologies include Qt, Java, Windows, .NET, web, mobile, and embedded systems; supported targets also include Linux, macOS, iOS, Android, MCUs, and hybrid applications. The Squish AI Assistant suggests script improvements, explains failures, and analyzes Runner and Server logs. Named CI/CD integrations include Jenkins, GitLab, and Bamboo, with Jenkins jobs and Pipeline scripts supported. Squish references ISO 26262 and IEC 61508 and offers a custom Tool Qualification Kit for project and regulatory needs. Floating user-based subscriptions are priced according to concurrent development environments and limit concurrent test executions. Pricing is on request, with a free trial available and no free plan.
