How to reuse Cucumber steps with Java

[Gergana Ivanova]

Hi, 

I try to reuse some Cucumber steps in Java like this:

@When("^I login as Patty$")

public void LoginPage(String userrole, String username,

String password) {

steps "When User Admin enters UserName Patty and Password pass123";

}

@When("^User (.*) enters UserName (.*) and Password (.*)$")

public void enterLoginDetails(String userrole, String username, String password){

MapleActions actions = new MapleActions(getDriver(), getDriverParams());

actions.sendKeysToElement(loginUsername, username);

actions.sendKeysToElement(loginPassword, password);

actions.clickElement(loginButton);

actions.perform();

}

And seems it is not possible with Java. Is there not reusing steps like in Ptthon and Ruby with Cucumber, is it, really?

Any help will be highly appreciated.

This particular case will not work. You are specifying three arguments
and your regular expression doesn't define any capture groups. You
will get a mismatch in this case.

capture three string arguments.

Cucumber will reuse steps if the regular expressions matches. That
behaviour is, as far as I know, consistent for all Cucumber
implementations.

Calling steps from steps is deprecated because, while it saves a little
work at first, it soon becomes very hard to maintain.

I suggest extracting the details to a helper method:

public void enterLoginDetails(String userrole, String username, String
password){
MapleActions actions = new MapleActions(getDriver(), getDriverParams());
actions.sendKeysToElement(loginUsername, username);
actions.sendKeysToElement(loginPassword, password);
actions.clickElement(loginButton);
actions.perform();
}

And then call that method from various steps:

@When("^I login as Patty$")

public void loginAsPatty() {
enterLoginDetails( lookupRoleFor("Patty"), "Patty",
"lookupPasswordFor("Patty");

}


@When("^User (.*) enters UserName (.*) and Password (.*)$")

public void loginAsParticularUser(String userrole,
String username,
String password) {
enterLoginDetails(userrole, username, password);
}

Note that I've implied other methods for retrieving shared test data
(lookupXyzFor() methods), but you could use embedded strings for Patty.
I quickly find that extracting such data from the body of the methods
makes things easier.

I hope that helps,
