How to pass a value from one step to another cucumber step

[Vinoth Kannan]

Say I have a step which generates a data and now I have another cucumber step where I need to pass that data and to get some expected result.

Is there any way for this other than saving a variable as global and storing the value in it

Which language are you using? Can you share a concrete example of the two step defs you'd like to share state between?

Thanks Richard for your reply.

i am using java with cucumber.

the below is a example step :

Given I go to "LoginPage.url" URL

And create an application 

And search the application created

I am creating an application and once it gets created it generates an application number ex: APP123 ,

now i want to copy this number and enter in the search text box and should verify that the application is displayed.

Thanks in advance

You have two scenarios here,

The first is that you can create an application e.g.

Given I am logged in

When I create an application

Then my application should be created

You can confirm that this works by looking at the application number.

The second scenario is that once an application is created you can search for it.

Given I have an application

When I search for my application

Then I should find my application

Now you could create you application in exactly the same way as in the first scenario, or you could bypass the UI and do it in a more direct manner.

Now you have an alternative way of getting the application name to be searched, you can just get the last application added to the database, ask for its name and then search on that name e.g.

When "I search for my application" do

  search_for_application name: Application.last.name

end

One other way to pass information in steps is to use a name when creating things: e.g.

Given I have an application wibble

When I search for the application wibble

Then I should find the application wibble

In this case your step defs can use the name (wibble) to do things e.g.

create_application name: 'wibble'

search_for_application name: 'wibble'

should_see_search_result name: wibble

some general rules

- global variables are the most powerful, most convenient and most dangerous mechanism,

- names in features are the least powerful, least convenient and the safest mechanism

- getting last (only) entry in the database is somewhere inbetween

All best

You also have the option of using the DI framework (by default PicoContainer (I think thats still the case) in Java) to pass around the state.  The webdriver example shows using this in a technical sense I believe, but you can also put the state of your 'world' (i.e. the test) in to injected objects.  Possibly slightly better than full global objects.

Cheers,

Matt

thanks matthew.

I am new to cucumber , has no idea about pico container. can some one please explain it or share some link to walk through it.

Is there any other way to perform this .

Thanks in advance friends.

Can someone Please help me on this.

This excerpt from the excellent "Cucumber for Java" book covers dependency injection in step definitions with Pico Container: https://media.pragprog.com/titles/srjcuc/simplify.pdf. (Which, by the way, I found by Googling "cucumber picocontainer" and looking at the first page of results. There's decent documentation online, but it does require a little searching.)

I'd recommend getting the whole book if you're going to be doing much work with Cucumber in Java.

Hope that helps,

Richard

If both stepdefs are defined on the same class you can just use a private member variable to store the necessary information.

Dependency Injection is not needed in this case, but it will be needed to share information between stepdefs defined on separate classes.

Hi Richard,

Thanks, i am not able to find about PICO container from your link..please help

Just read the PDF that Richard linked and you'll understand. After you
read the PDF, you should consider but the book: it's an amazing
resources for people that are starting with Cucumber (and not just for
those).
