Cucumber-JVM 3 - io.cucumber.datatable.UndefinedDataTableTypeException

Question

I updated from Cucumber-JVM 2.4.0 to 3.0.2 in my pom.xml and DataTables started throwing this exception:

io.cucumber.datatable.UndefinedD

Answer 1

It has been totally revamped. XStream has been removed , so earlier code will not work.

You will need to add logic for datatable and parameter conversion. Refer to these - https://github.com/cucumber/cucumber/tree/master/datatable and https://github.com/cucumber/cucumber/tree/master/cucumber-expressions . Place below class code inside a package defined in the glue option.

public class Configurer implements TypeRegistryConfigurer {

    @Override
            public void configureTypeRegistry(TypeRegistry registry) {

    registry.defineDataTableType(new DataTableType(Income.class, new TableEntryTransformer() {
                    @Override
                    public Income transform(Map entry) {
                        return new Income(entry.get("name"),entry.get("amount"),entry.get("frequency"));
                    }
                }));
            }

            @Override
            public Locale locale() {
                return Locale.ENGLISH;
            }

        }
