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.UndefinedDataTableTypeException: Can't convert DataTable to List< jcucumberng.steps.pojos.Income >. Please register a DataTableType with a TableEntryTransformer or TableRowTransformer for class jcucumberng.steps.pojos.Income
I changed all my imports to
import io.cucumber.datatable.DataTable;
I did an mvn clean install
and compilation was successful but steps involving DataTables no longer work after the update.
Current code:
// Feature
When I Enter My Regular Income Sources
| name | amount | frequency |
| Salary | 25000 | every 2 weeks |
// Stepdef
@When("^I Enter My Regular Income Sources$")
public void I_Enter_My_Regular_Income_Sources(DataTable dataTable) throws Throwable {
List<Income> incomes = dataTable.asList(Income.class);
// More code
}
// Custom type
public class Income {
private String name = null;
private String amount = null;
private String frequency = null;
public Income(String name, String amount, String frequency) {
this.name = name;
this.amount = amount;
this.frequency = frequency;
}
// Getters and setters
}
Is there a new way to use the DataTables in Cucumber-JVM v3.x.x?
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<Income>() {
@Override
public Income transform(Map<String, String> entry) {
return new Income(entry.get("name"),entry.get("amount"),entry.get("frequency"));
}
}));
}
@Override
public Locale locale() {
return Locale.ENGLISH;
}
}
