In the project directory, open in LightTable:
ModuleName.jl with functions under development (Capitalize jl-file names containing modules, match file and module names)usingfile.jl that does include("ModuleName.jl") (which allows reloading without Julia restart, see FAQ)In the ./test/ sub-directory, put the file with FactCheck tests for ModuleName functions: collect all tests into one file named modulename.jl, i.e. the same as source but without capitalization and residing in the testing sub-directory. Open it in LightTable as well.
