Cucumber - using the value generated from the first step to all the other steps

[Gheeno San Pascual III]

Description : How do you reuse value generated from the first step.

Cucumber: 

Given user is generated 

And user can login 

Then the user can see the profile page. 

Java 

```

UserGenerator.class

String user;

Given("{} is generated")

public String getUserId(String userType) {

// method here to generate the userId

userId = user;

}

Steps.Class

And("{} can login")

public void login(String user) {

// how do I call the value made in the getUserId method 

}

```

What would be the best approach to store a value made from a step and then be used again ( the same value ) on another step?

Thanks for the insight.

> Steps.Class

>

>
> Given("{} is generated")

> public void generateUser(String userType) {
> user = new UserGenerator().getUserId(userType);

> }
>
> And("{} can login")
> public void login(String user) {

In cucumber there are 3 ways you can communicate between steps. 2 involve looking up things by a reference in subsequent steps, the 3rd uses global variables.

Following examples are in Ruby, I'll leave it up to others to translate to Java.

1. Implicitly:

Your subsequent steps look up the last record in the database of the thing you are interested in, e.g.

Given 'there is a user' do

   create_user

end

When 'the user logs in' do

   user = User.last

   login_user(user)

 end

2. By name:

Given 'there is a user Fred' do

  create_user(name; 'Fred')

end

When 'Fred logs in' do

  user = User.where(name: 'Fred').first

  create_user(user)

end

3. By using a global variable. The variable is global in Cucumber's World object and so can be accessed in other step definitions

Given "I am a user" do

  @i = create_user

end

When "I login" do

  login_user(@i)

end

There are advantages and disadvantages to each approach, and each approach effects the language of the scenarios.

I rarely use 1 now. I use 2 occasionally particularly when talking about interactions between multiples e.g. stuff involving users Fred and Sue. I use 3 most of all, and in particular use it with singleton concepts like i, my, mine etc. However I have to warn you that using globals safely requires great discipline, and its very easy to create a great deal of mess if you do it badly. So I'd suggest using 2 if you can't meet those criteria.

All best

You are supposed to implement the 'world' concept and dependency injection.

Thank you for the insight Georgia.

PicoContainer did the trick for my project.
