BDD: Cucumber Hello World Using Java and IntelliJ

Categories: Java; Tagged with: bdd • cucumber • Java • TDD; @ March 14th, 2015 16:42

Example:

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)

import org.junit.Assert;

import java.math.BigDecimal;

    @Before
    public void setUp() {
        fxConverter = new FxConverter();
    }


    @Given("^currency:\"([^\"]*)\", amount:(\\d+)$")
    public void currency_amount(String currency, BigDecimal amount) throws Throwable {
        fxConverter.setCurrencySource(currency);
        fxConverter.setAmountInput(amount);
    }

    @Given("^fxRate is (.+)$")
    public void fxRate_is_(BigDecimal rate) throws Throwable {
        fxConverter.setFxRate(rate);
    }

    @When("^convert to \"([^\"]*)\"$")
    public void convert_to(String currency) throws Throwable {
        fxConverter.convertTo(currency);

    }

    @Then("^the result is (.+) in CNY$")
    public void the_result_is_in_CNY(BigDecimal resultExpected) throws Throwable {
        assertTrue(resultExpected.compareTo(fxConverter.getAmountResult()) == 0);
    }

}
