how to use a feature file within another
Hi I want to create a complete login feature file and write its unit tests. And I could run that unit tests, whenever I want. After, I want to create another feature file (let's call it filling a ...

Hi again
I created this feature file for the login:
Scenario Outline: Login into account with correct credentials
And User clicks on the login button on homepage
And User enters a valid username "<username>"
And User enters a valid password "<password>"
When User clicks on the login button
Examples:
| username | password |
| user1 | 123456 |
And this is the step definition for the login:
@Given("User clicks on the login button on homepage$")
@Throws(Throwable::class)
fun user_clicks_on_the_login_button_on_homepage() {
loginPage!!.clickOnSignInButton()
}
@Given("^User enters a valid username \"([^\"]*)\"$")
@Throws(Throwable::class)
fun user_enters_a_valid_username(username: String?) {
loginPage!!.enterUserName(username)
}
@Given("^User enters a valid password \"([^\"]*)\"$")
@Throws(Throwable::class)
fun user_enters_a_valid_password(password: String?) {
loginPage!!.enterPassword(password)
}
@When("User clicks on the login button$")
@Throws(Throwable::class)
fun user_clicks_on_the_login_button() {
loginPage!!.clickOnSubmitButton()
}
I used the login functions inside the step definition of the form, in this way:
@Given("^User logged in with valid username and password$")
@Throws(Throwable::class)
fun user_logged_in_with_valid_and() {
LoginSteps().user_clicks_on_the_login_button_on_homepage()
LoginSteps().user_enters_a_valid_username()
LoginSteps().user_enters_a_valid_password()
LoginSteps().user_clicks_on_the_login_button()
}
@Then("^User clicks on the processes page$")
@Throws(Throwable::class)
fun user_clicks_on_the_processes_page() {
fillingFormPage!!.clickOnProcessesPage()
}
But I have a problem that says no value passed for parameter username and password, which is right.
So, I changed the step definition for the form like this:
@Given("^User logged in with valid username and password$")
@Throws(Throwable::class)
fun user_logged_in_with_valid_and(username: String?, password: String?) {
LoginSteps().user_clicks_on_the_login_button_on_homepage()
LoginSteps().user_enters_a_valid_username(username)
LoginSteps().user_enters_a_valid_password(password)
LoginSteps().user_clicks_on_the_login_button()
}
@Then("^User clicks on the processes page$")
@Throws(Throwable::class)
fun user_clicks_on_the_processes_page() {
fillingFormPage!!.clickOnProcessesPage()
}
But also when I run the test, I face this problem:

So, I had to change the feature file of the form from this:
Feature: Fill the form
Existing user should be able to log in using correct credentials and fill the form
Background: : logged in user
Given User logged in with valid username and password
Scenario: Login into account with correct credentials and fill the form
And User clicks on the processes page
to this:
Feature: Fill the form
Existing user should be able to log in using correct credentials and fill the form
Background: : logged in user
Given User logged in with valid "<username>" and "<password>"
Scenario: Login into account with correct credentials and fill the form
And User clicks on the processes page
also, I had to change the step definition of the form from this:
@Given("^User logged in with valid username and password$")
@Throws(Throwable::class)
fun user_logged_in_with_valid_and(username: String?, password: String?) {
LoginSteps().user_clicks_on_the_login_button_on_homepage()
LoginSteps().user_enters_a_valid_username(username)
LoginSteps().user_enters_a_valid_password(password)
LoginSteps().user_clicks_on_the_login_button()
}
@Then("^User clicks on the processes page$")
@Throws(Throwable::class)
fun user_clicks_on_the_processes_page() {
fillingFormPage!!.clickOnProcessesPage()
}
to this:
@Given("^User logged in with valid \"([^\"]*)\" and \"([^\"]*)\"$")
@Throws(Throwable::class)
fun user_logged_in_with_valid_and(username: String?, password: String?) {
LoginSteps().user_clicks_on_the_login_button_on_homepage()
LoginSteps().user_enters_a_valid_username(username)
LoginSteps().user_enters_a_valid_password(password)
LoginSteps().user_clicks_on_the_login_button()
}
@Then("^User clicks on the processes page$")
@Throws(Throwable::class)
fun user_clicks_on_the_processes_page() {
fillingFormPage!!.clickOnProcessesPage()
}
But, when I run the test, the username and password fields, filled with these values:
username: <username>
password: <password>
But I want them to be filled with these values:
username: user1
password: 123456
Which I defined in the feature file of the login.
What can I do to pass the correct values???
If you need a dedicated test for your login form, your first example was fine.
For your other scenario, you could have a before hook which do all the login at once using support code, no steps.
Your login/password may be part of that support code, it is not relevant to appear in your features.
That may look like the following pseudo-code:
// A before hook:
Before {
LoginUserAs('user-1', '123456')
}
// In some support code
function LoginUserAs(username, password) {
// Do all the steps to login a user:
// - Open the login page
// - Fill the form
// - Submit the form
// - ...
}
