canopy
An F# web automation and testing library built on Selenium with C# compatibility.
What is canopy?
Canopy is a web automation and testing library for F# that provides a clean, concise syntax for browser automation tasks. Built on top of Selenium, it simplifies writing reliable tests and automation scripts while maintaining compatibility with C# projects.
F# developers and teams needing to write browser automation or UI tests, especially those already using or considering Selenium but wanting a more concise syntax. It also targets C# developers who want to leverage F#'s expressiveness for automation within .NET ecosystems.
Developers choose Canopy over raw Selenium for its intuitive, readable F# API that reduces verbosity and friction in automation code, while still leveraging Selenium's reliability and offering seamless C# interoperability.
Overview
f# web automation and testing library, built on top of Selenium (friendly to c# also)
Use Cases
Best For
- Writing browser automation scripts in F# with a concise, readable syntax.
- Creating UI tests for web applications using Selenium without the typical verbosity.
- Integrating browser automation into .NET projects that use both F# and C#.
- Teams transitioning from Selenium in C# to a more expressive F# testing approach.
- Learning web automation in F# through practical examples and starter kits.
- Automating real-world web interactions with production-ready examples and documentation.
Not Ideal For
- Projects targeting non-.NET ecosystems or languages beyond F# and C#
- Teams seeking visual or no-code automation solutions for rapid prototyping
- High-performance, headless automation where Selenium's overhead is unacceptable
- Environments requiring extensive third-party integrations outside Selenium's scope
Pros & Cons
Pros
Offers an intuitive, readable API that reduces verbosity compared to raw Selenium, as emphasized in the README's focus on simplicity and productivity.
Leverages the robust Selenium WebDriver for stable browser control, ensuring compatibility with various browsers and versions, which is a core foundation.
Seamlessly integrates with C# projects, as shown by the C# examples in the repository, allowing mixed-language .NET teams to adopt F#'s expressiveness.
Provides real-world examples and a starter kit linked in the README, enabling quick onboarding and production-ready testing scenarios.
Cons
Inherits Selenium's drawbacks, such as slower execution speeds and the need for manual browser driver management, adding setup complexity.
Primarily designed for F#, so developers unfamiliar with functional programming or .NET may face a steeper learning curve and limited community support.
Has a smaller ecosystem compared to mainstream automation tools in Python or JavaScript, resulting in fewer plugins and community-driven extensions.
