how to use coverlet as project in a solution

[Nitin5acc]

Hello,

we would like to use this source code and create coverlet .net core projects in our application (sln) which can be used on other projects to check coverage.
We have taken the code from this repo and added it in our solution. However, no coverage is generated.

Hi Nitin,

it's not clear to me your question...would you like to have a coverage after run your test projects?
You need to follow the guide https://github.com/tonerdo/coverlet#installation
Why you download sources?

[Nitin5acc]

Hello, we would not like to use coverlet as package. We want to bring source code into our solution, build the same and use that as dll to check the coverage on other projects.

Also, we are using the release 5.2.2 version as its new and advance but the package(coverlet.collector) version is 1.1.0

Why?I mean coverlet needs some steps to work...if you want to use directly che code you need to follow more or less what console do https://github.com/tonerdo/coverlet/blob/master/src/coverlet.console/Program.cs#L64

Coverlet need to do some steps https://github.com/tonerdo/coverlet#how-it-works

BTW we have future plan to expose coverlet core as stand alone package for custom coverage #212

Coverlet works in 3 different way and it depends on "drivers".
We can run using custom .NET tool, msbuild tasks injection or integrated inside vstest as collectors. So depends on how you want to use it, the more secure way is through collectors due to some know issue https://github.com/tonerdo/coverlet/blob/master/Documentation/KnowIssues.md#1-vstest-stops-process-execution-earlydotnet-test

Hello,
We cloned all three projects - Core, Collector, and Console but still, we see no coverage file. Do you have any samples where source code was used?

[MarcoRossignoli]

As I've said above you can copy .net tool usage https://github.com/tonerdo/coverlet/blob/master/src/coverlet.console/Program.cs#L64 we don't have an example on codebase
Maybe @shargon can help here, they used coverlet by code.

TL;DR; We don't have an example because at the moment core features are designed only for internal usage so they're not stable until we'll release core coverlet features as "standalone".

[MarcoRossignoli]

At the moment we're blocked on vstest bug, after that fix we can go on with hiding all class and design a stable api to expose internal features microsoft/vstest#2221

[shargon]

You have an example in https://github.com/red4sec/TuringMachine

More concretely in https://github.com/Red4Sec/TuringMachine/blob/master/src/TuringMachine.Core/Helpers/CoverageHelper.cs

@Nitin5acc feel free to close if solved, thanks @shargon for the sample!
