About The Project

A lightweight library for using dependency injection in cucumber steps for Micronaut based project.

Built With

• Java 11
• Micronaut
• Maven

Getting Started

Features

• Cucumber steps dependency injection using the Micronaut dependency injection mechanism. Only constructor dependency injection is supported

• Bean discovery by type

• Bean discovery by name. See micronaut @Named annotation usage.

• Bean discovery by parameterized type

Build

1. Clone the repo

git@github.com:david-romero/cucumber-micronaut.git

2. Build the library

mvn clean package

Installation

1. Clone the repo

git@github.com:david-romero/shared-payments.git

2. Install the library

mvn clean install

Usage

Dependency

Add the maven dependency

  <dependency>
    <groupId>com.davromalc</groupId>
    <artifactId>cucumber-micronaut</artifactId>
    <version>0.1.0</version>
  </dependency>

Configuration

The Micronaut Object Factory needs to be configured as cucumber object factory.

import com.davromalc.cucumber.micronaut.MicronautObjectFactory;
import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;
import io.cucumber.junit.CucumberOptions.SnippetType;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class) //Cucumber does not support JUnit 5 yet
@CucumberOptions(
    plugin = {"pretty", "html:target/features"},
    glue = {"com.davromalc.cucumber.micronaut.examples.acceptance"},
    objectFactory = MicronautObjectFactory.class,
    features = "classpath:features", snippets = SnippetType.CAMELCASE)
public class CucumberRunnerITCase {

}

Steps usage

1. Beans definitions

import javax.inject.Singleton;

@Singleton
public class World {
  
}

@Singleton
final class AddFriend implements UseCase<AddFriendParams, User> {

  private final FriendRepository friendRepository;

  public AddFriend(FriendRepository friendRepository) {
    this.friendRepository = friendRepository;
  }

  @Override
  public Either<Validation, User> execute(AddFriendParams params) {
     //Implementation...
  }
}

2. Step implementation

package com.davromalc.cucumber.micronaut.examples.acceptance.steps;

public class AddFriendStep {

  private final UseCase<AddFriendParams, User> addFriend;

  private final FriendRepository friendRepository;

  private final World world;

  public AddFriendStep(@Named("addFriend") UseCase<AddFriendParams, User> addFriend, FriendRepository friendRepository,
      World world) {
    this.addFriend = addFriend;
    this.friendRepository = friendRepository;
    this.world = world;
  }

  @Given("a new friend with name {string}")
  public void aNewFriendWithName(String friendName) {
    world.setFriendParams(new AddFriendParams(friendName));
  }


  @When("the friend is added")
  public void theFriendIsAdded() {
    addFriend.execute(world.getFriendParams());
  }

  @Then("the new friend {string} has been saved")
  public void theNewFriendHasBeenSaved(String newFriendName) {
    final Optional<String> newFriendNameFromDatabase = friendRepository.findByName(newFriendName)
        .map(User::getName)
        .filter(newFriendName::equals)
        .findAny();
    assertThat(newFriendNameFromDatabase)
        .matches(Optional::isPresent)
        .get()
        .asString()
        .isEqualTo(newFriendName);
  }
}
