.NET Data Collection for CLR Profilers

This repository contains examples of data collectors and test suites
that show how to attach a CLR profiler to the .NET runtime (Core or
Framework) during a test session.

How It Works

Test suites can be configured to use a data collector. The data collectors in this
repository set CLR environment variables so that a profiler is
attached to the runtime. The profiler can then instrument the tests and generate a
execution trace.

Instructions

.NET Core

• Get a profiler DLL (cs_dotnet_tracer.dll).
• Build the CoreSample solution with dotnet build or Visual Studio.
• Adjust the paths in CoreSample.Tests/collect.runsettings.
• Remove the [Ignore] directive from the TestEnv case. This will ensure that the data
  collector was found and initialized by the test runner. Processor Architecture).
• Run the tests with dotnet test --settings collect.runsettings in CoreSample.Tests.
• Check that trace.cst and cs_dotnet_tracer.log have been created in the output
  directory (specified by <OutputDir> in collect.runsettings.

.NET Framework

• Get a profiler DLL (cs_dotnet_tracer.dll).
• Build the Visual Studio solution FrameworkSample.
• Adjust the paths in FrameworkSample.Tests/collect.runsettings.
• Configure Visual Studio to use the settings (Test → Test Settings →
  Select Test Settings File).
• Remove the [Ignore] directive from the TestEnv case. This will ensure that the data
  collector was found and initialized by the test runner.
• Run the tests.
• Check that trace.cst and cs_dotnet_tracer.log have been created in the output
  directory (specified by <OutputDir> in collect.runsettings.
