When you implemented your feature file, number of Arity with parameters are missing.
Say, your step is as below.
in your step defination file, you can write as below
When I am at chennai today at restauran
and your impl looks like this
@When("I am at (.*) (today | tomorrow) at restaurant")
public void at(String cityName){
}
you can either add one more parameter
@When("I am at (.*) (today | tomorrow) at restaurant")
public void at(String cityName, String whenExactly){
}
or you can change your step defination impl like this
@When("I am at (.*) (?:today | tomorrow) at restaurant")
public void at(String cityName){
}
Hope that helps.
