Applies a converter to the elements inside a collection

All 2 scenarios hold

A static @TypeConverter method in the test class decides what a cell's text becomes. A table can then use the language of the domain, in place of programmer literals.

Three converters serve the tables below. Yes/No becomes a boolean. A number word becomes an integer. A day word becomes a date.

Each rule below keeps the conversion visible. Each table pairs the text of the cell with the value the test method receives, printed back as plain text. That column is a String, and no converter touches a String. The column therefore shows what the converter produced, and does not restate what the converter was given.
