altcover.fake

Contains options to run AltCover as part of dotnet test within a Fake build script.

Usage

Given specifications prepare, process and collect (part of the API), extend a dotnet test invocation with coverage collection

open AltCoverFake.DotNet.DotNet // extension method WithAltCoverOptions
Fake.DotNet.DotNet.test (fun to' -> to'.WithAltCoverOptions prepare collect process) "dotnettest.fsproj"

See the Wiki page for full details

What's in the box?

APIs for integration into Fake build scripts -- what one might expect to see as a module Fake.DotNet.Testing.AltCover, just like the other Fake.DotNet.Testing.* modules, only built and maintained with the rest of the tool.

Why altcover?

As the name suggests, it's an alternative coverage approach. Rather than working by hooking the .net profiling API at run-time, it works by weaving the same sort of extra IL into the assemblies of interest ahead of execution. This means that it should work pretty much everywhere, whatever your platform, so long as the executing process has write access to the results file. You can even mix-and-match between platforms used to instrument and those under test.

In particular, while instrumenting .net core assemblies "just works" with this approach, it also supports Mono, as long as suitable .mdb (or .pdb, in recent versions) symbols are available. One major limitation here is that the .mdb format only stores the start location in the source of any code sequence point, and not the end; consequently any nicely coloured reports that take that information into account may show a bit strangely.

Why altcover? -- the back-story of why it was ever a thing

Back in 2010, the new .net version finally removed the deprecated profiling APIs that the free NCover 1.5.x series relied upon. The first version of AltCover was written to both fill a gap in functionality, and to give me an excuse for a ground-up F# project to work on. As such, it saw real production use for about a year and a half, until OpenCover reached a point where it could be used for .net4/x64 work (and I could find time to adapt everything downstream that consumed NCover format input).

Fast forwards to autumn 2017, and I get the chance to dust the project off, with the intention of saying that it worked on Mono, too -- and realise that it's déja vu all over again, because .net core didn't yet have profiler based coverage tools either, and the same approach would work there as well.

Possible retirement/obsolescence of support

tl;dr -- legacy framework/Mono support is not going away any time soon.

As net472 can consume netstandard2.0 libraries (everything but the recorder), and .net core 2+ can consume net20 libraries (the recorder), legacy framework/Mono support continues until such a time as it is no longer possible to retain those API levels.

This build from https://github.com/SteveGilham/altcover/tree/80615807948cdb63e203a358eac7ceb881b41825

Q. Never mind the fluff -- how do I get started?
A. Start with the Quick Start guide : https://github.com/SteveGilham/altcover/wiki/QuickStart-Guide and
read the FAQ : https://github.com/SteveGilham/altcover/wiki/FAQ

8.6.40 (Habu series release 20)
• [BUGFIX] Issue #178 - possible NRE when instrumenting woven code e.g. using Fody
• [AvaloniaVisualizer] Now requires net5.0 or later
• Supports Fake 6.0.0.  This is probably the last release that will support earlier versions, as 5.23.1 is almost 6 months old.
• Supports net8.0 previews 1,2 (so far, no nasty surprises like with the 7.0.100 release)

8.6.14 (Habu series release 19)
• [GTKVisualizer] Fix an off-by-one crash for coverlet generated files
• [AvaloniaVisualizer] Fix possible crash launching the About dialog
• [Visualizer] Display coverage percentages against nodes of the tree (known issue that the synthetic F# module nodes are not thus decorated)
• [Visualizer] Improve handling of larger coverage files by deferring more processing until the tree model is actually expanded.
• [API] Types Options.CLI, Options.Logging, Options.Prepare and Options.Collect in namespace AltCover; concrete implementations of the ICLIOptions, ILoggingOptions and IPrepareOptions and ICollectOptions respectively, with getter and setter for each property.  Default values for the latter two are as per the corresponding Primitive record types.
• [API] Also on the AltCover.Fake package in the AltCoverFake.DotNet.Testing namespace (except Options.Logging which is not useful in that context)

8.5.842 (Habu series release 18)
• [VISUALIZER] As the relevant Avalonia issue is long resolved, move to having separate dialog boxes for the Avalonia Visualizer's "About" and message box, as in the GTK# version.
• ref struct types have an autogenerated [Obsolete] attribute with a standard comment - detect and ignore such attributes.  See https://turnerj.com/blog/ref-structs-are-technically-obsolete for details.

8.5.841 (Habu series release 17)
• To support Cake 3.0, move the Cake API assembly from AltCover.Api to a new package AltCover.Cake; this contains libraries built against Cake 2.0.0 at netcoreapp3.1 as well as the old ones built against Cake 1.0.0 at netstandard2.0 (present but in practice obsolete).
• Following Fake.build's policy of deprecating releases older then 6 month, drop support for versions before 5.23
• [BREAKING] Rename AltCover.Cake.DotNet.DotNetCoreTest to AltCover.Cake.DotNet.DotNetTest (even in the obsolete 1.0.0 build) to match the changes in the Cake APIs (and consequent chage to the test setting type in the argument list).  Similarly, in the version >= 2.0.0 build, the type AltCover.Cake.DotNet is now a [CakeAliasCategory("DotNet")] rather than [CakeAliasCategory("DotNetCore")]
• [API] New DotNet APIs for Fake support - ToTestPropertiesList method to emit a list of (name,value) pairs to allow customised property passing to dotnet test in the wake of the v7.0.100 regression.
• [API] Additionally ImportModuleProperties and GetVersionProperties values that are additonal lists of (name,value) pairs to append as needed.
