Your readme says: use (=>>), but compiler says it's deprecated

Which one is it?

Support inheritance in imported tests

Consider inherited tests when importing tests from NUnit/MbUnit/etc

Move to fsprojects?

I think this library has a lot of potential; wouldn't it be great if it was moved to fsprojects for everyone to contribute to? It would increase its exposure.

FSharpx and PowerPack question

Hello.

By trying to build solution I'm getting:

Error   10  The type referenced through 'Microsoft.FSharp.Collections.LazyList`1' is 
defined in an assembly that is not referenced. You must add a reference to assembly 
'FSharp.PowerPack'. D:\TFS\Fuchu\Fuchu.Tests\Prelude.fs 4   6   Fuchu.Tests

Does FSharpx really depending on PowerPack?
If So then why NuGet doesn't resolve it?
Or should it be added to some packages.conf?

Assert expected, actual -> Assert actual, expected

Switching order for these would make it easier to read:

I Assert.Equal("because some context, that",``computed value``(), "is this string").

let config = { FsCheck.Config.Default with MaxTest = 10000 }

let properties =

Any thoughts? Thanks.

Take explicit dependency on FSharp.Core

It helps to manage assembly bindings, rather to do trial-and-error

Sign it please?

Could we just put a random Fuchu.snk and sign it? A bit of a PITA to work with unsigned assemblies from signed assemblies. Reverse is OK.

Parallel test running from NUnit/MbUnit

Check that tests imported from NUnit/MbUnit can be run in parallel. I think not.

inline ==> clashes with Fakes definition

I note that this definition is obsolete in this project.

Can you delete it from the source? It clashes with Fake; so you can't import both libraries in the same file!

Build on AppVeyor?

I found it is pretty convenient and free to integrate AppVeyor. It can build all commits (or, if you wish, tags) and push to NuGet automatically.

See for example: https://github.com/intellifactory/fsock

dotnet test adapter

After #50 , implement the adapter for dotnet test to work.

Docs are currently dismal so I guess we'd have to dive into xunit or nunit's code.

dotnet test protocol

After #54 look into https://docs.microsoft.com/en-us/dotnet/articles/core/tools/test-protocol

Flag for randomising order

Something akin to this PR would be really nice to have in Fuchu; especially coupled to parallel running of tests.

Stack trace in assertion failures

The stack trace in assertion failures is incorrect.

How to use the initializer only once for multiple tests?

open Fuchu

let clo f () = 
    printfn "Initializing..."
    let mem = 2 // Allocate some unmanaged resources (like GPU memory for example.)
    f mem
    printfn "Freeing..."

/// Applies a function to a value
let inline testFixture' setup (name, partialTest) = 
    testCase name (setup partialTest)

let test1 x = printfn "Doing something with that memory..."
let test2 x = printfn "Doing something else with that memory..." 
let test3 x = printfn "Third test that uses the memory..."
let testCombined x = test1 x; test2 x; test3 x // How do I get this to count as 3 tests instead of 1?
let tests = testFixture' clo ("3 tests",testCombined)
run tests

Alternatively, just using testFixture, is it possible to use the setup only once, pass the resulting parameters to the tests and dispose of it afterwards? To be honest this is quite a puzzler, and I have no idea how to deal with this. In XUnit or NUnit (assuming there weren't bugs making the adapter unable to find the tests) I would just use a fixture class.

With the example I found on the blog, the setup would have to be triggered each time for every test. I think there should be a middle ground between loading the thing every time and loading it only once outside of the test suite.

Any idea how?

Incorrect total time when running tests in parallel

The reported total running time is calculated from adding up all individual test running times, which for parallel test running is obviously more than the actual wall clock time.

ExpectedExceptionAttribute

Support ExpectedExceptionAttribute when converting from MbUnit/NUnit tests.

Fuchu to MbUnit

Write a function to map Fuchu tests to MbUnit tests, as described in http://bugsquash.blogspot.com/2012/06/fuchu-functional-test-library-for-net.html?showComment=1364172010713#c6294531064534333851 .

This would enable alternative runners like Gallio.

TestDriven.Net integration

Implement TestDriven.Framework.ITestRunner

add ability to customize default printers

"run" and "runParallel" customize TestPrinters.Default and use it to print outputs for failed and exceptions. It would be nice to provide a way to either customize TestPrinters.Default or allow run/runParallel take custom TestPrinters.

My goal is to have verbose printing and print information about passed tests.

It would also be nice to somehow print progress. Perhaps pass to BeforeRun # of test about to be run / # of tests total?

Add Fuchu pronunciation to README

Currently there is no pronunciation guide for "Fuchu". Is it like "Foo choo", "Fuh choo", "Fuhkoo", or "foo koo" or something entirely different .

Update PerfUtil to latest version to avoid binding exceptions

Test tree local resources

https://github.com/feuerbach/tasty/blob/master/core/Test/Tasty/Core.hs#L128-L155

Count subclasses of failure exceptions as failures

Currently things like Xunit.Sdk.EqualException are counted as errors instead of test failures.

Support MbUnit's MultipleCultureAttribute

MultipleCultureAttribute can be present at the method, type, or assembly level.

Assertable extensibility

Like http://hackage.haskell.org/packages/archive/HUnit/1.2.5.1/doc/html/Test-HUnit-Base.html#g:3 , but obviously instead of a typeclass use a dictionary of Type -> ((unit -> 'a) -> (unit -> unit)) and reflection. Or use statically resolved inline classes: https://github.com/gmpl/FsControl

This would enable a simpler syntax for those cases when you only want to check equality or some boolean result.

Better formatting of output

As a tester,
When writing failing tests,
I want to quickly be able to see differences between expected and actual output
And I want to quickly see where there the test cases start and stop in the output.

Example output that takes times to parse:

Semi-blocking for SuaveIO/suave#340 SuaveIO/suave#334 (can solve by downgrading FsCheck, I think)

Possible source of the error:

let fsCheckConfig = { Config.Default with Arbitrary = [ typeof<Arbs> ] }

// later:

    testPropertyWithConfig fsCheckConfig "200 OK returns equivalent" <| fun respStr ->
      (runWithConfig (OK respStr) |> req HttpMethod.GET "/hello" None) = respStr

Has @fscheck an API breakage in a minor release? /cc @kurtschelfthout

Fuchu.TeamCity package name

❤️ this library!

Just wondering, what's with the rather unusual package id for Fuchu.TeamCity https://www.nuget.org/packages/Fuchu-suave.TeamCity/ ? I'm guessing @haf did this off on a fork and the package was just never renamed, is that right? Would you be open to a PR to unify it with the others?

Structural equality bug (failure despite equality)

I have some code that creates a test case:

let encoding_equal<'a when 'a : equality> f_encode text expected (message : obj) =
  testCase text (fun () ->
    Assert.Equal(text, expected, f_encode (message :?> 'a)))

Getting failure like this:

Expected: {compression = Nope;
 key = seq [];
 value = seq [];}
Actual: {compression = Nope;
 key = seq [];
 value = seq [];}

Structure:

type Message =
  { compression : Compression
  ; key         : byte System.ArraySegment
  ; value       : byte System.ArraySegment }
