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

Use DataTableType annotation

@DataTableType
public Income incomeEntry(Map entry) {
    return new Income(entry.get("name"), entry.get("amount"), entry.get("frequency"));
}

Then you can directly use the list of the custom class in step definition

@When("^I Enter My Regular Income Sources$")
public void I_Enter_My_Regular_Income_Sources(List incomes) throws Throwable {
    // More code    
}
