Background with multiple data - cucumber-java

I have 2 username and password combination and I have a scenario after that.I want to login with username1,password1 and complete the scenario and then want to login with username2,password2 and complete the scenario.I have defined login in background.Is this possible in cucumber?Any inputs will be helpfull.TIA..

It is not possible according to cucumber documentation.
You can only have one set of Background steps per feature. If you need different Background steps for different scenarios, you’ll need to split them into different feature files.

If you want to run the same scenario with different inputs, you can use Scenario outline and use the first username & password in the first Example, and the second in the second Example.
If that is your question, I wonder why you want to rerun the same Scenario with a different username and password? Do the different users have different roles for example and both should be able to do something? Consider whether each scenario / example illustrates a particular behaviour in your application.

How to implement 'if' in Gherkin

I am trying to convert Selenium test to Gherkin. Is there way to implement if statements in Gherkin?
Example : assume the code is written in the below format. I am just writing description as below. Please understand the part after double slash is the actual Selenium code:
// launch the application
// login to application
// navigate to page
String str;
if(str== "XYZ")
{
// verify title
}
//verify text field 1
//verify test field 2
//verify select box
For this I am trying to write code in Gherkin as follows
Given user launches the application
When user login with valid credentials
and navigate to required page
When String str is "XYZ"
Then verify title
And verify text field 1
And verify test field 2
And verify select box
but this code is incorrect because if the str is not equal to "XYZ" we want that title should not be verified but other verification like text field1,2 and select box should be verified.
You don't implement if in Gherkin.
Gherkin is about communication and those you want to communicate with, non coders, don't know what an if statement is. They don't care either.
The solution? Two scenarios to cover both cases.
Ideally, this level of detail would not be in your Gherkin scenario. The best approach is describe business use cases, not low level details. This is what Gherkin is designed for: communicating with non-technical stakeholders so that you can work out if you are building the right thing in the first place. Here is what I would write:
Given the user is logged in
And the user is on the required page
When they enter data that requires the optional fields to be validated
And they enter invalid data in the optional fields
Then the form shows an error on the optional fields
The low level details don't matter (that the string is specifically "XYZ" or that it is the title field is not important), so these should be hidden in the step definition and/or unit tests.
In order to continue to check the other fields, you can just add another step after this:
When they enter invalid data in all of the other fields
Then each other field has an error message attached to it.
Again, there is no need to specify the actual fields, or separate them into their own steps. The idea is to express the high level business value of the scenario, i.e. that the form is validated when it should be.
The advantage to keeping things high level is that when the form changes (as it eventually probably will), then this scenario can remain untouched. Which is correct as the business case is the same: it should validate when it's supposed to. All the changes will be in the step definitions. This means that there is no reason to have another discussion with your stakeholders about whether your scenarios are still testing the right thing.
You can write the scenario, somewhat like this:
Given the user launches the application
When user login with valid credentials
And navigates to required page
Then he should see the page datails
Inside the Then step you manage all the logic.
Then(/^he should see the page details$/) do
if condition
...
else
...
end
end
Gherkin is not a programming language to use if or else conditions. It is a part of BDD framework, that is implemented, to make the stakeholders and other non technical resources understand what the test process is about. Hence, it is always recommended, you keep the gherkin as simple and as generic as possible.
Strictly speaking you should create an alternative statement along the lines of:
Given user launches the application
When user login with valid credentials
and navigate to required page
When String str is NOT "XYZ"

Getting output of one scenario as input to another scenario in cucumber

I am using cucumber in combination with selenium for testing the java web application. The following is the Scenario that we have
get generate PIN page
enter user name
enter password
click on submit button
Now it generates a PIN in the database depending on so many calculations. now i need that particular PIN, to give it as an input to a different scenario. how can i achieve this? Thanks in advance.
I would assume that you can access the PIN within the database after the above scenario. That being the case, I would add one more step to the scenario that acquires - and confirms - that the PIN was indeed generated. At that point, you can store the PIN in a local variable and then use it within the next scenario.
So your first scenario would look like this:
Get generate PIN page
Enter user name
Enter password
Click on submit button
Confirm PIN number in database
The last step would not be done within Selenium, but via an API call or some other means to acquire the PIN from the database. It would confirm the PIN (e.g.; regex=/^\d{4}$/) and then store it in a local variable, say something like #customer_pin (assuming you're using Ruby).
Your next scenario would start off something like this:
Get generate login page
Enter customer ID
Enter customer PIN
etc
When you hit the "Enter customer PIN" step, you pull it from the locally stored variable (#customer_pin).
My advice is that when executing this second scenario, you confirm that you have a legitimate PIN within your locally stored variable, in case someone should run this scenario out of sequence. You could do this by using a global variable and running a "Before" hook in your features/support/env.rb file like this:
Before do
$dunit ||= false
return if $dunit
$customer_pin = nil
$dunit = true
end
In this case, I use $customer_pin instead of #customer_pin in order to make the variable globally accessible. Then after running your first scenario, $customer_pin would be assigned to a legitimate value so that it can be used in any subsequent scenarios. Subsequent scenarios would use the regex expression to confirm it has a legitimate value, and raise/throw an exception if not.
I would divide your problem into two.
One that verifies the pin generation as this may be important for your stakeholders.
One that implement a backdoor to support other cases where a valid PIN is needed. Maybe an API that is able to generate or retrieve a valid pin number. Maybe create and store the PIN in the database without touching the system from the outside. I would use this way to retrieve a PIN whenever I need a valid PIN for other scenarios.
The technical solution on how to get a valid PIN isn't too important. What is important is to decouple the execution order of the scenarios. The execution order of the scenarios is undefined. Each scenario must be able to be executed in isolation and in random order.
Coupling scenarios is a well known anti pattern described here and here.
To Solve this kind of situation you have to use Cucumber Background feature, This is run before each step. and will generate a PIN based on given inputs and then generated PIN will be available across the scenarios.
Find feature file definition based on your requirements.
Background:
Given I Get generate PIN page
Then I Enter user name
And Enter password
And I Click on submit button
And I Confirm PIN number in database
#TC01_GetUserInformationByPinTest #NoBrowser
Scenario: Get User information by generated PIN from background.
Given I Get User Information by using generated PIN
And I verified that given username is same as response Data
I believe this will help you to solve your issue.

How to Login only one time and then run a lot of scenarios

I'm a newbie in BDD and i would like to know how can i do some step before the beginning of my scenarios but only one time.
Concretely, i would like to login in my website and do some scenarios.
Currently, i have a background which log my user and after i have some scenarios.
The problem is that for all of them, my background is repeated.
How can i do to avoid that ?
Thank you in advance.
Feature:
User's module verification.
As a user, i have to be able to manage my profil.
# Background do an user's connection and go to his profile.
Background:
Given I am logged in
# -------------------SUMMARY MANAGEMENT---------------------
#javascript #success #raz #summary
Scenario: Deletion of the summary.
When I click on the element at xpath "//*[#id='presentation']"
And I write in the element at xpath "//*[#id='profile-content-presentation']/div/div/div[2]/div/span/div/form/div/div[1]/div[1]/textarea" value ""
And I click on the element at xpath "//*[#id='profile-content-presentation']/div/div/div[2]/div/span/div/form/div/div[1]/div[2]/button[1]"
And I wait for 1 seconds
Then I should see "Aucun résumé pour l'instant"
You could use behat hooks to automatically log user in before every scenario.
You could also combine this with tags to avoid logging user in, in scenarios taged in a certain way (or do the opposite, depending on how many of each you have).

Load Runner facing isse during Dyanmic data handling

I am using load runner 9.5. I am facing a problem during Dyanmic data handling. Scenario is given below-
I have Library management application. Login-> Select book(data display based on User credential) -->Purchage and Logout.
Ex: Guest user: 50 Books display to choose
Admin : All Books display choose
Normal user : 100 Bokks display choose
Please help me How to handle these type of dynamic data based on user role. Is there need to create different script with different role ?
Please follow the below steps -
Record the same flow with the same user credential 2 times (Replica of first script)
Compare the scripts using W diff
Find the values which are different like purchase order, timestamp and user session.
Correlate the values which are highlighted in yellow means value which is different in each script.
Have you had the benefit of training in LoadRunner and a mentor for your first year of work in this field?

Is it possible to reuse a feature as the "Given" for another feature?

Is it possible to reuse a feature as the "Given" for another feature?
Or am I trying to do something I shouldn't be trying to do
basically my features look like:
Scenario: Creating a basic account with valid details (happy path)
Given I am on the "signup" page
And I enter all the right details #this is shortened of about 20 steps for your reading ease
When I press the button labelled "Sign up"
Then I should see the text "Thanks for signing up"
And I should have an email from "confirmation#mysite.com" titled "Confirm your account Michael"
And the database should contain a record for the user marked as unconfirmed
Scenario: Confirming account via email
Given I have created a basic account
When I open the confirmation email and visit the url to confirm the account
Then I should be logged in
And the database should contain a record for the user makred as confirmed
I clear my DB after every feature as they should all be able to be run individually...
Am I going about this the wrong way?
Thanks
The Problem
What you're actually attempting is to reuse a scenario. This is no longer supported in Cucumber.
Aside from other problems with this approach, your tests will be slower and interdependent, since you will be:
driving account creation through a browser, and
making all your tests dependent on the account-creation test passing.
Don't do that.
The Cucumber Way
Generally, you should write your tests to work independently, although you can certainly reuse step definitions. So, in the general case, you might want to add shared steps like:
Given that user account "Test User" does not exist
Given that user account "Test User" exists
which can then be included in your scenarios as needed. The nice thing about this approach is that the steps can create or delete users programmatically.
Alternatively, if most of your tests will be on existing accounts, set up the default data set with the right user fixtures already in place. For the limited subset where you will be testing account creation, just add a scenario background that drives user deletion.
In case you are using Javascript, I've created a package named reuse-cucumber-scenarios for calling a scenario by doing:
Given the scenario "#scenario_tag"
.
Given the scenario "#scenario_tag" with parameters
"""
{
"1": ["step1_param1", "step1_param2"],
"2": ["step2_param1", "step2_param2", "step2_param3"],
"3": ["step3_param1", "step3_param2", "step3_param3"],
}
"""
or creating gherkin variables...
Given the variable "$variable_name" is equal to
"""
#JSON object
"""
or creating scenario functions and calling them by doing...
Given the scenario "#$scenario_function_tag" where variable "$variable_name" is "value_to_replace"
and more...
Currently, you can use the following approach:
Background:
Given Some common setup
And Some more setup
Scenario: one
When setup1
Then something1
Scenario: two
When setup2
Then something2
