Cucumber 4 Optional Words?

@Then("a topic is (not) displayed on the chat icon of the menu")

Basically I want the not to be optional if possible? Previously it was (is|is not).

Adding that is|is not is part of the capturing group, entered as a String in the stepdef.

Solution

  • If you want to use regular expressions you should start your strings with ^ and/or end them with $. Otherwise Cucumber will treat them as Cucumber expressions. So:

    @Then("^a topic (is|is not) displayed on the chat icon of the menu$")
public void a_topic_is_displayed(String isDisplayed){

}

    If you do want to use Cucumber expressions then you'll have to capture the modifier in a parameter type. So:

    @Then("a topic {isOrIsNot} displayed on the chat icon of the menu")
public void a_topic_is_displayed(boolean isDisplayed){

}

    And you'd register a parameter type to convert the string to a boolean:

    typeRegistry.defineParameterType(new ParameterType<>(
    "isOrIsNot",                     // name
    "is|is not",                     // regexp
    boolean.class,                   // type
    (String arg) -> "is".equals(arg) // transformer function
))
