Properties

FakesCompilationProperties

Format : <property name1>=<property value1>;<property name2>=<property value2>;

None

Yes

KeyFile

FakesCommandLineArguments
  with "/key:<filepath>"

Path to the KeyFile for signing the fakes assembly.

<filepath>

None

Yes

ProjectTemplate
 

FakesCommandLineArguments
  with "/pt:<projfilepath>"

Path to a .proj file which will be used as a template for creating fakes  assembly's.proj file. This option can be used to further customize fakes code generation if the rest of the options don’t suffice. For ex. Add a prebuild/postbuild event for the fakes assembly. Attaching a basic sample  template to start with.

<<ProjectTemplate.csproj>>

<proj file path>

None

Yes

MsbuildPath

FakesMsbuildPath

Path to the msbuild executable to be used for compiling fakes assemblies

<msbuild executable file path>

As specified by $MSBuildToolsPath

No

FrameworkPath
 

FakesBinPath

Directory Path where Microsoft.QualityTools.Testing.Fakes.dll is present

<directory path>

"C:\Program Files (x86)\MSBuild\Microsoft\ VisualStudio\v12.0\Fakes"

No

OutputPath

FakesOutputPath

Path to be used for dumping the generated fakes assemblies after copying them from intermediate path

<directory path>

<currentdirectory>\ FakesAssemblies

No

IntermediatePath
 

FakesIntermediatePath

Path to be used for dumping the intermediate code generated during creating fakes assemblies

<directory path>

<currentdirectory>\obj

No

CleanIntermediatePath
 

FakesCommandLineArguments
  with "/clean"

Delete the intermediate code that gets generated during fakes creation.

NA

False

No

ForceIntermediatePath
  (depcrecated)

FakesCommandLineArguments
  with "/fip"

Normally for each assembly, a folder is created under the intermediate path using the assembly name. If this option is set, the folder creation for each assembly does not happen, and instead the same folder is shared for all assemblies.

NA

False

No

ForceReadOnly

FakesCommandLineArguments
  with "/f"

If during fakes code generation or fakes compilation a file already exists as readonly, it won't get overwritten. Setting this option to true will ensure all readonly files are replaced.

NA

False

No

TargetX86

ForceX86

Force fakes engine to run as 32-bit process. Ideally the bitness is automatically determined from the assembly to be faked.

NA

Bitness as specified by the assembly to be faked

Yes

Elevated

FakesCommandLineArguments
  with "/admin"

Launch Fakes engine as elevated process. Ideally, if the invoking process is elevated, fakes process will automatically be launched elevated.

NA

Invoking process' elevation state

No

FakesFilesOnly
 

FakesCommandLineArguments
  with "/mfo"

Let's fakes accept only .fakes file, instead of accepting a .dll directly.

NA

False

No

ProcessCount

FakesCommandLineArguments
  "/pc:<integer>"

Number of concurrent fakes processes to spawn for generating Fakes. Ideally, if multiple assemblies are to be faked, fakes will automatically figure out and spawn the appropriate number of parallel processes based on machine's CPU Cores. This option can let you tune (lower) this value if required.

<integer>

Minimum of
{Number of CPU Cores, Number of fakes assemblies to be generated}

No

Leaf

FakesCommandLineArguments
  with "/l"

There are situations when the fakes engine needs to re-launch itself under a different environment to suite the Bitness/CLR/Elevation requirements. In some cases this might lead to an infinite invocation loop. This option can be used to avoid fakes re-launch itself  to avoid ending up in such a situation.

NA

False

No

Verbosity

FakesVerbosity

Verbosity level of Fakes engine.
