cucumber jvm varargs support in step definition

[Mrunal Gosar]

How to use power of varargs while defining step definitions in cucumber java bindings. I have below step

Given I have following product: prod1, prod2, prod3

Here product list can be variable.

My Step definition

@Given("^I have following product [(exhaustive list of products or pattern of the product names)]$")
public void stepDef(String...args)
{
//Process varargs array "args" in here
}

I know workaround can be to except the complete string after colon and then in the code break the string using split(",") and dump it into array. But i just want to know if cucumber on its own supports varargs pattern.

TIA!!!

I recommend using a data table instead:

Given I have the following products:

  | prod1 |

  | prod1 |

  | prod1 |

Then in your stepdef:

@Given("I have the following products:")

void stepdef(List<String> products) {

} 

 Here product list can be variable.

My Step definition

@Given("^I have following product [(exhaustive list of products or pattern of the product names)]$")
public void stepDef(String...args)
{
//Process varargs array "args" in here
}

It doesn't support varargs. If you don't like the table approach above you can still create a list:

@Given("I have the following products: (.*)")

void stepdef(List<String> products) {

} 

See https://github.com/cucumber/cucumber-jvm/issues/364 and https://github.com/cucumber/cucumber-jvm/pull/371

Hi Aslak

Thanks for replying. I had my eyes on the solution which you had suggested, but just wanted to get confirmed whether i've missed this feature in cucumber-JVM (if it already exists).

i read your post that varargs implementation is there in ruby bindings, so just thought to lookup if it is there in java bindings.

Thanks

I confirm there is no varargs support for Java stepdefs.

Thanks
