Add possibility to give warning when coverage is below the threshold instead of just failing the build

[roostaamir]

Currently there is a possibility in the MSbuild tool to specify a threshold for the coverage result and if the coverage percentage is below the threshold, then the build fails

We have a requirement in our project to just give warnings when coverage is lower than the threshold (instead of failing it). Therefore, I think it could be a good idea to add an option to the threshold functionality to specify whether the build should fail or just give a warning.

Thank's for the advice, we'll wait to see thumb up and comment from community.

I'm working on a local version of the change myself. Can I do a pull request for this or should I wait for thumbs ups?

[MarcoRossignoli]

It depends, are you adding one more switch?

[roostaamir]

Yes.

[MarcoRossignoli]

Can you update top issue with the proposal idea?So we can talk about.

[roostaamir]

Sure. I will add a snippet tonight

Sorry for the delay. This weekend was not my best.

So here's how I wanted to tackle this problem. First I would introduce a new CommandOption for the console to accept. Something like this:

CommandOption thresholdAction = app.Option("--threshold-action", "The action to take when coverage is below the threshold value. Defaults to stop the build", CommandOptionType.SingleValue);

Then I would use an Enum to determine the actions possible, which in this case would be something like Warning and FailBuild.

I would later get the argument like this:
var dThresholdAction = thresholdAction.HasValue() ? Enum.Parse<ThresholdAction>(thresholdAction.Value(), true) : Enum.Parse<ThresholdAction>("FailBuild", true);

In the end, if coverage was less than the threshold value (and of course the threshold value was specified) I would check the thresholdAction. If it was the default, I would let the process go as it is right now and throw the exception that is already throwing. However, if the action was to give warning them I would just do a logger.LogWarning() call instead

I tried to keep the naming convention and code style. But the naming and style of code could be different of course.

Let me know if this sounds plausible to you.

@roostaamir looks fine to me, if you work on this you should also add same new switch to msbuild version https://github.com/tonerdo/coverlet/blob/master/src/coverlet.msbuild.tasks/CoverageResultTask.cs#L214

@MarcoRossignoli I'm finished with my pull request about this:
#720

The only thing I did not know about was the versioning of the package. Please lift the version however you see fit :)

did this make it in? Would love to see this capability

@Danny-UKDM No up to now this didn't make it in. But every contribution is welcome. So you or someone else can reopen the PR and continue.
