Question 1

How do I set up Unquote with xUnit in an F# project?

Accepted Answer

Install the Unquote NuGet package, then use the test function or convenience operators like =! in your xUnit test methods. No extra configuration is needed—xUnit automatically catches exceptions thrown by Unquote for failure reporting.

Question 2

Unquote vs Expecto: which should I use for F# testing?

Accepted Answer

Unquote excels at detailed expression traces and static checking via quoted expressions, ideal for debugging complex assertions. Expecto offers a broader feature set like property-based testing and parallel execution. Choose Unquote for clarity in failures, or Expecto for more comprehensive testing workflows.

Question 3

Can Unquote handle async code in F# tests?

Accepted Answer

Yes, but you need to embed async expressions within quoted assertions carefully. Unquote will reduce them step-by-step, but it may require wrapping async operations to ensure proper evaluation in test contexts.

Question 4

How do I assert exceptions with Unquote in F#?

Accepted Answer

Use the raises operator, e.g., raises <@ 1 / 0 @>, or raisesWith for more complex checks with predicate functions, as detailed in the README for exception testing.

Question 5

What are the limitations of Unquote's expression decompiler?

Accepted Answer

The decompiler supports many F# constructs but may not handle all language features perfectly. Refer to the Decompiler Features wiki for specifics; some complex expressions might not decompile to clean single-line strings.

Question 6

Is Unquote compatible with .NET 6 and later?

Accepted Answer

Yes, Unquote is compatible with modern .NET versions including .NET Core and .NET 5/6/7/8, as it relies on standard F# quotations which are supported across these runtimes.
