How to use ignore-methods

[kreghek]

I use Stryker to test my project. And I want to exclude some "auto-generated" methods like ToString and GetHashCode.

The command to run Stryker looks like:
-ignore-methods "['ToString', 'ConfigureAwait', '*Exception.ctor', 'Equals', 'GetHashCode']"

But I has no effect:

Expected behavior
The methods are ignored and don't appears in report.

Desktop (please complete the following information):

• OS: ubuntu-latest
• Type of project: .NET Standart
• Framework Version 2.0
• Stryker Version 0.22.0

Hi @kreghek

The ignore methods option only ignores methods calls, not method bodies. For method bodies you'll want to use the ignore code coverage attribute.

Hi @rouke-broersma ,

I am not sure which "ignore coverage attribute" you make reference too. May you provide an example please? I have a method (GetFeatures) covered by functional tests and I would like to exclude it from stryker.

ex:

        public List<Feature> GetFeatures(DirectoryInfo directoryInfo, string conditions)
        {
            var gherkinParser = new GherkinParser();
            var matches = new List<Feature>();
            foreach (var file in directoryInfo.GetFiles("*.feature", SearchOption.AllDirectories))
            {
                var gherkinDocument = new gherkin.Parser().Parse(file.FullName);
                if (gherkinParser.GetScenarios(gherkinDocument, conditions).Count() > 0)
                {
                    matches.Add(gherkinDocument.Feature);
                }
            }

            return matches;
        }

Thanks for your support!

Ouch... I just understood that the attribute is the "System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverageAttribute".
It does the job!

using System.Diagnostics.CodeAnalysis;

[ExcludeFromCodeCoverage]
public List<Feature> GetFeatures(DirectoryInfo directoryInfo, string conditions)
{
   ...
}

Thanks
