JBehave暧昧的一步

Question

Say I have:

@Given("first name is $firstName")
@Given("first name is $firstName and last name is $lastName")

The following step would be marked as ambiguous:

Given first name is John and last name is Smith

Without using quotes to surround the first parameter, how can I fix this step so it only matches the second one? Using quotes to surround both the parameters separately also has the same ambiguity issue.

Is there a limit on how long each parameter is? Are there certain characters that can't be passed in?

Answer 1

You can solve this by using step priorities, as documented here: http://jbehave.org/reference/stable/prioritising-steps.html

Your problem would be solved by setting a higher priority to the variant with two parameters:

@Given("first name is $firstName")
@Given(value = "first name is $firstName and last name is $lastName", priority = 1)

I tried your example and with this combination, the two steps were separated.

(Edit: my initial solution had quotes for the parameters, but it works without as well)

Answer 2

I think this scenario can be write this way:

Given first name is John
And last name is Smith

And the steps:

@Given("first name is $firstName")
@And("last name is $lastName")

You can create the person object first an set the name and the last name in the "@Given" steps.
If you need add another property, like email, you just need create another step:

@And("the email is $email")
public addEmail(String email) {
    person.setEmail(email);
}

So this problem not gonna happen and you code will be more reusable.

Answer 3

What worked for me was substituting ankle brackets (<>) for the dollar sign ($), ie

@Given("a person with first name <firstName>")

and

@Given("a person with first name <firstName> and last name <lastName>")
