mausch/Fuchu

Fuchu is a cross-platform testing framework for F\# and C\# that supports execution in .NET, JavaScript (via Fable), and various CI/CD environments. It provides core testing capabilities including property-based testing with FsCheck, structured result reporting, and compatibility with existing MbUnit and NUnit test suites. The system also includes specialized modules for performance benchmarking with visualization and integration with TeamCity for continuous integration reporting.

8 changes.

The project modernized its build infrastructure by migrating to .NET SDK-style projects and updating dependencies, while significantly expanding its cross-platform capabilities through Fable and C\# support. New features included deep integration with FsCheck for property-based testing, TeamCity CI reporting, and the ability to import and run existing MbUnit and NUnit test suites.

This period focused on extending the Fuchu test framework by adding support for MbUnit conversion and performance benchmarking via PerfUtil. It also introduced charting capabilities for visualizing performance data and established a dedicated test runner for the Fable compiler environment to ensure robust execution and failure propagation.

A new C\# test project (Fuchu.CSharpTests) has been added to demonstrate the library's capabilities in C\#. It showcases defining tests using extension methods, composing setup and teardown logic via fixtures and higher-order functions, skipping tests, and integrating with FsCheck for property-based testing. The entry point includes a custom test runner that wraps tests with timeouts and custom logging.

Introduced a new Charting module that enables visualization of performance test data. Users can now generate bar charts for specific metrics via the \plot\ function, which filters out failed results and displays session IDs against the measured values, and the \plotMS\ function, which automatically groups test sessions and plots elapsed time in milliseconds. The charts are rendered using FSharp.Charting with a styled grid layout.

This release updates the Fuchu test library to version 1.2.0-beta-2, targeting the .NET 8 SDK (global.json) and Fable 4.27. It introduces a new Fable test project (Fuchu.FableTests) and a Fable build configuration in the solution, enabling users to run tests in JavaScript environments. The build system is modernized with FAKE and Paket, and the solution now includes additional integration projects for MbUnit, PerfUtil, and TeamCity.

This change introduces the Fuchu.FsCheck module, which allows users to define FsCheck property-based tests directly within the Fuchu test framework. It provides a \testProperty\ function for F\# and a \FsCheck.Property\ static member for C\# that accepts \Func\ delegates of varying arities (1 to 4 arguments), automatically wrapping the FsCheck runner to map test outcomes to Fuchu's test results. The integration also handles FsCheck's \IgnoreException\ by re-raising it as a test skip/ignore event.

Added a new component in the Fuchu.MbUnit library that converts Fuchu test definitions into MbUnit test structures. This allows users to run their existing Fuchu tests using the MbUnit runner, bridging the two testing frameworks.

Adds the Fuchu.PerfUtil library, which integrates the Fuchu test framework with PerfUtil to enable performance benchmarking. This new module provides functions to create performance tests (\perfTest\), compare implementation performance against alternatives (\testPerfImpls\), and track historical performance trends over time (\testPerfHistory\), allowing users to detect performance regressions and optimize code within their Fuchu test suites.

The Fuchu.TeamCity module now provides a runner that integrates with JetBrains TeamCity CI/CD. It utilizes the JetBrains.TeamCity.ServiceMessages.Write library to stream test results, supporting the reporting of passed, failed, and ignored tests, as well as handling exceptions and durations.

Fuchu version 1.1.0 introduces the ability to import and run existing MbUnit and NUnit test suites via new Fuchu.MbUnit and Fuchu.NUnit modules, which reflect on test attributes and execute them within Fuchu. The library now provides structured display for test result counts and formats exceptions to be clickable in Visual Studio. Assembly metadata is now generated programmatically via FAKE and signed with a strong-name key, and the public API has been refined for C\# compatibility, including renaming TestResult.Exception to Error and exposing specific modules.

The XML documentation file for the FSharpx.Core library has been removed from the project. This change eliminates the generated documentation source for the library, which previously included summaries for types such as FSharpx.BS and FSharpx.FSharpFunc.

Added Fable-specific test runner with non-zero exit code handling; Initial test suite for Fuchu.

The project has migrated from legacy .NET Framework 3.5 project formats to the modern .NET SDK-style project system, enabling support for .NET Framework 4.5.2 and .NET Standard 2.0 (with .NET Core 2.1 for test projects). This change updates core dependencies, including FSharp.Core to 4.6.2, FsCheck to 2.14.0, NUnit to 3.12.0, and Fable tooling packages (Fable.Core 3.1.6, Fable.Promise 2.1.0, Fable.Fetch 2.2.0). Build tooling dependencies (FAKE) are also updated to version 5.20.3 via Paket.
