Cucumber\Java: Defining a step with both optional words and parameter

Question

Although similar to Optional parameter in cucumber, still it is for ruby programmers which I am not familiar with...

So what I'd like to have is to be able to use either one of those two options:

Given REST ADCC Login with username "admin" and password "admin"

and

Given REST ADCC Login with username "admin"

For the latter I would allow myself to set the password with the username value for testing purposes only.

The step implementation as I understood is:

@Given("^REST ADCC Login with username \"(.*)\"(?: and password \"(.*)\")?( negative)?$")
public void login(String username, String password, String negative) {
        loginLogoutStepsHandler.login(username, password);
}

but then, when I use the first step option, with the password defined, the password param gets null as it should have been "admin".

What is wrong with my syntax?

Thanks!

Create two step definitions. Call one from the other:

@Given("REST ADCC Login with username \"(.*)\" and password \"(.*)\"")
public void restADCCLoginWithUsernameAndPassword(String username, String password) {
    // log in...
}

@Given("REST ADCC Login with username \"(.*)\"\"")
public void restADCCLoginWithUsernameAndPassword(String username) {
    restADCCLoginWithUsernameAndPassword(username, "test");
}

It achieves code reuse without getting clever with regular expressions.

Thanks! It didn't work for me. However, I managed to find the solution, also following your idea to abandon the single step solution :) As you can see, the changes between your solution and the one which worked are minor. Thanks again! – dushkin Aug 20 '19 at 13:16
To be clear, the `.*` regex construct is greedy by default so the second regexp matches everything between the first and last quotes – ashley Apr 12 '22 at 12:12
Oh, geez. I didn't realize the two steps were so similar. The `.*` syntax would have caused both steps to be a match for the `with password` variant. – Greg Burghardt Apr 12 '22 at 12:20

for whoever may be of interest for them, what eventually worked (following the idea of Greg of using two separate implementations) for me was:

@Given("^REST ADCC Login with username \"([^\"]*)\"$")
public void rest_ADCC_Login_with_username(String username) throws Throwable {
    loginLogoutStepsHandler.login(username, username);
}

@Given("^REST ADCC Login with username \"([^\"]*)\" and password \"([^\"]*)\"$")
public void rest_ADCC_Login_with_username_and_password(String username, String password) throws Throwable {
    loginLogoutStepsHandler.login(username, password);
}
