Simple Profiler

Idea

The main idea of this project it to show a way to add 'profiling' methods calls into 'measured' methods.

How it works

Basically we have a main project ShugiShugi that hold a reference to ShugiShugi.Common project to make ETW calls. Then we have a ShugiShugi.Test project that run usual XUnit tests agains ShugiShugi project.

What I want to do - is to dynamically add 'Test started' and 'Test finished' functions calls in each XUnit test method. So it gonna look like this:

    [Fact]
    public void TestFunc1()
    {
        Log("Test started");

        // test code here
        // Assert.xxxxx

        Log("Test finished");
    }

Note: I'm doing it on tests function because we have to choose functions where to add dynamic code. Methods that have attributes is easy to Select, otherwise I have to manually pass the names of the methods....

To make it interesting the Log functions themselves will be also dynamically generated in ShugiShugi.Common project.

So here are the steps:

1. Select all methods that have [Fact] attribute on them
2. On each method:
   • Create new method in ShugiShugi.Common project with the name of test method + Log as a method name
   • Inject IL code to call this method above in the beginning and end of test function

• This project use Mono.Cecil as an engine to insert IL code

Quick start

1. Clone
2. Build
3. Checkout the ShugiShugi.Test.dll file with ilSpy or any other assembly code viewer

Features

• Added MSBuild Target to ShugiShugi.Test project that will automatically run LogWrapper on ShugiShugi.Test output DLL
