Platform value types

All 14 scenarios passing

Cell text converts automatically to the declared parameter type, with no type converter to write. Every table below reads the same way: an Input value column holding the text as written in the cell, the parameter type it is converted to, and expectation columns stating observable properties of the object the test method received — so each row shows that the text became a valid object of that type, not merely that it converted. A parameter type is fixed by the test method signature and cannot vary by row, so each type gets its own short table.
