created TestConverter and test for that class
fixed test for TestConverter
added more test methods to TestConverterTest
TestConverter returns status and assertion
changed TestConverter, output is an array of status and assertion/code
running assertions for code samples with #=>, with errors

the context of the sample is missing
the test runs and tests
changed test - empty string input now returns warning
created AtaruError to catch StandardErrors if they occure and output
them with more info(md filename, code sample number). Created some more mock files.
