Find a trailing comma in a JSON fixture
Locate a deliberate syntax error before handing a fixture to another tool.
Set up the example
Validate the practice file, remove the extra comma immediately before the closing bracket, then validate again.
Check the result
The initial input should fail. After removing that one comma it should parse as a one-record array containing A17.
