[BUG] ExcludeFromCodeCoverage does code exclude method in a partial class that contains a linq expression #1548
Description
Describe the bug
Please share a clear and concise description of the problem.
To Reproduce
I have the following class under Test
public partial class StuffMcStuffy { private readonly ILogger<StuffMcStuffy> _logger; public StuffMcStuffy(ILogger<StuffMcStuffy> logger) { _logger = logger; } [LoggerMessage( EventId = 0, Level = LogLevel.Information, EventName = "testname", Message = "tes:extraction {JobId} {ExtractionStatus} {ExtractionError}")] private partial void RecordExtractionEvent(Guid jobId, string extractionStatus, string extractionError); [ExcludeFromCodeCoverage] public void DoThis() { Console.Write("do this"); } public void DoThat() { Console.Write("do that"); } public void BlahThis() { var thislist = new List<KeyValuePair<string, object>>(); thislist.Add(new KeyValuePair<string, object>("hey", "ho")); thislist.Add(new KeyValuePair<string, object>("hey1", "ho1")); var blah = CreateLoggerDictionary(thislist); blah.ToString(); } [ExcludeFromCodeCoverage] private static Dictionary<string, string> CreateLoggerDictionary(List<KeyValuePair<string, object>> attributes) { return attributes.ToDictionary(item => item.Key, item => item.Value.ToString() ?? string.Empty); } }I used the following script to run the unit tests and generate the coverage reports
#!/usr/bin/env bash set -euo pipefail find . -type d -name TestResults -exec rm -rf {} + rm -rf ./codeCoverageReport PROJECTS="$(find . -type d -name "TestProject1")" readonly PROJECTS for project in ${PROJECTS}; do dotnet test -c Release "$@" "${project}" --collect:"XPlat Code Coverage" --logger "console;verbosity=normal" --logger trx done dir=$(CDPATH= cd -- "$(dirname -- "$0")" && pwd) REPORT_TYPE=Html COMMAND=open FILENAME=index.html TARGETDIRECTORY="$(ls -d "${dir}"/.)/codeCoverageReport" REPORTS="$(find "${dir}/.." -type f -name "coverage.cobertura.xml" | tr "\n" ";")" dotnet ~/.nuget/packages/reportgenerator/*/tools/*/ReportGenerator.dll \ -reports:"${REPORTS}" \ -targetdir:"${TARGETDIRECTORY}" \ -reporttypes:"${REPORT_TYPE}" && \ "${COMMAND}" "${TARGETDIRECTORY}/${FILENAME}"Expected behavior
The method CreateLoggerDictionary() should be excluded from test coverage
Actual behavior
The method is not excluded from coverage
** Workaround **
Rewrite the code using foreach()
private static Dictionary<string, string> CreateLoggerDictionary(List<KeyValuePair<string, object>> attributes) { Dictionary<string, string> dictionary = new Dictionary<string, string>(); foreach (var attribute in attributes) { dictionary.Add(attribute.Key, attribute.Value.ToString() ?? string.Empty); } return dictionary; }
