We can store our tests as files in the file system.
There is a choice of three formats for writing tests:
We can mix tests in different formats within a test suite, but an individual test page must be in one format.
We can use any editor that we like for each format.
To run tests from the file system, we use Folder Runner
pathToFitSharp\runner -r fit.Runner.FolderRunner -c c:\myfolder\mysuite.config.xml
dotnet pathToFitSharp\runner.dll -r fit.Runner.FolderRunner -c c:\myfolder\mysuite.config.xml
