Adding support to generate WiX version files

[ruhullahshah]

• Create WiX version files from GitVersion variables using the CLI which can allow smoother integration with WiX project workflows.
• Partially addresses Feature request: GitVersionTask with C++, WixToolset projects support #1132
• Usage: GitVersion.exe /updatewixversionfile
• Sample output attached
  GitVersion_WixVersion.zip

Thanks for this. If it's possible to test this in any way, I would appreciate a few tests. 😄

[ruhullahshah]

You are welcome. I have added some testcases that cover the use cases scenarios for this patch

[asbjornu]

Why only GitVersionExe tests and not for GitVersionCore? Also, don't you agree approval tests such as this is better suited for file manipulation testing such as this?

GitVersion/src/GitVersionCore.Tests/AssemblyInfoFileUpdaterTests.cs

Lines 26 to 40 in ee5b77a

	public void ShouldCreateAssemblyInfoFileWhenNotExistsAndEnsureAssemblyInfo(string fileExtension)
	{
	var fileSystem = new TestFileSystem();
	var workingDir = Path.GetTempPath();
	var assemblyInfoFile = "VersionAssemblyInfo." + fileExtension;
	var fullPath = Path.Combine(workingDir, assemblyInfoFile);
	var variables = VariableProvider.GetVariablesFor(SemanticVersion.Parse("1.0.0", "v"), new TestEffectiveConfiguration(), false);
	using (var assemblyInfoFileUpdater = new AssemblyInfoFileUpdater(assemblyInfoFile, workingDir, variables, fileSystem, true))
	{
	assemblyInfoFileUpdater.Update();
	fileSystem.ReadAllText(fullPath).ShouldMatchApproved(c => c.SubFolder(Path.Combine("Approved", fileExtension)));
	}
	}

Could you please explain this in detail?

[asbjornu]

Yes, sure. Approval tests allows you to create a file on disk that is what the test is compared against. If the content matches, the test is successful, otherwise it fails and a diff is presented.

The above test will verify the manipulated file content against the following approved text file:

GitVersion/src/GitVersionCore.Tests/Approved/cs/AssemblyInfoFileUpdaterTests.ShouldCreateAssemblyInfoFileWhenNotExistsAndEnsureAssemblyInfo.approved.txt

@ruhullahshah, can you please find time to address the code review comment regarding approval testing, rebase and resolve the conflicts of this PR?

[ruhullahshah]

I will resolve the pending work in #1599,
