BDD: Cucumber Hello World Using Java and IntelliJ

Categories: Java; Tagged with: ; @ March 14th, 2015 16:42


Feature: Convert between different currencies
  Scenario: Convert SGD to CNY
    Given currency:"SGD", amount:10
    Given fxRate is 4.60
    When convert to "CNY"
    Then the result is 46 in CNY

JUnit Test: it can be generated by cucumber plugins, but not perfect for my IDE. (cannot generate all steps, but you still can copy the generated JUnit code from the output)

package com.liguoliang.bdd;

import cucumber.annotation.Before;
import cucumber.annotation.en.Given;
import cucumber.annotation.en.Then;
import cucumber.annotation.en.When;
import org.junit.Assert;

import java.math.BigDecimal;

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertTrue;
