cucumber.runtime.CucumberException: java.util.regex.PatternSyntaxException: répétition illégale près de l'index 39

Face à des erreurs de répétition après avoir exécuté des tests à partir de la classe Java

J'ai essayé de modifier / mettre à jour mes étapes et mon fichier runner mais malheureusement cela n'a pas aidé à résoudre mon problème. Je suis assez nouveau dans le concombre et le maven, donc si les informations que j'ai fournies sont moins, faites-le moi savoir.

Je pense qu'il essaie d'utiliser {int} comme quantificateur .

Il est fort probable que Cucumber interprète {int} comme un quantificateur. Bien que j'ai trouvé des exemples de Cucumber qui prennent en charge votre syntaxe regex actuelle avec @Given , et j'ai également trouvé des exemples qui utilisent une syntaxe alternative. Au lieu de ceci:

@Given("^User enters a valid username(\\d+)$")
public void user_enters_a_valid_username(Integer int1) {
    System.out.println("user_enters_a_valid_username2");
}

utilisez ceci:

@Given("^User enters a valid username{int}$")
public void user_enters_a_valid_username(Integer int1) {
    System.out.println("user_enters_a_valid_username2");
}

Merci beaucoup Tim. Cette solution a résolu le problème.

Vous pouvez remplacer le nom de votre étape par une étape sans chiffres comme "L'utilisateur donné accède au deuxième site Web de stackoverflow".

@Given("^User navigates to stackoverflow website(\\d+)$")
public void userNavigatesToStackoverflowWebsite(int arg0) {
}

Si vous voulez utiliser un veriable, vous pouvez utiliser comme ceci:

@Given("^User navigates to stackoverflow second website$")
public void userNavigatesToStackoverflowSecondWebsite() {
}

Les accolades sont les jetons d'ouverture et de fermeture du quantificateur de répétition {n, m}. C'est pourquoi l'exception Répétition illégale est lancée.

Il n'est pas nécessaire de créer 2 définitions d'étape différentes pour une seule et même étape dont le paramètre est différent.

Je suggère de combiner les définitions d'étape suivantes:

Feature: Login into account
Existing user should be able to login account using correct credentials

Scenario Outline: Login into account with correct credentials
Given User navigates to stackoverflow "<website>"
  And User clicks on the login button on "<homepage>"
  And User enters a valid "<username>"
  And User enters a valid "<password>"
When User clicks on the login "<button>"
Then User should be taken to the succesful login "<page>"

Examples:
  | website  | homepage  | username  | password  | button  | page  |
  | website1 | homepage1 | username1 | password1 | button1 | page1 |
  | website2 | homepage2 | username2 | password2 | button2 | page2 |

Given User navigates to stackoverflow "website"

INTO p>

@Given("^User navigates to stackoverflow \"([^\"]*)\"$")
public void userNavigatesToStackoverflow(String arg0) {
    // Write code here that turns the phrase above into concrete actions
}

L'étape de cornichon correspondante sera:

@Given("^User navigates to stackoverflow website{int}$")
public void user_navigates_to_stackoverflow_website(Integer int1) {
    System.out.println("user_navigates_to_stackoverflow_website2");
}

De cette façon, vous utiliserez la même définition d'étape dans les deux scénarios et uniquement le paramètre fourni sera différent. Cela évitera la répétition. Vous devez modifier toutes vos étapes en suivant ce modèle.

Dans votre cas, vous pouvez utiliser le plan du scénario:

 @Given("^User navigates to stackoverflow website$")
public void user_navigates_to_stackoverflow_website() {
    System.out.println("user_navigates_to_stackoverflow_website");
}
