What is FluentLenium ?

FluentLenium helps you writing readable, reusable, reliable and resilient UI functional tests for the browser.

FluentLenium provides a Java fluent interface to Selenium, and brings some magic to avoid common issues faced by Selenium users.

FluentLenium is shipped with adapters for JUnit, TestNG and Cucumber, but it can also be used standalone.

FluentLenium best integrates with AssertJ, but you can also choose to use the assertion framework you want.

Choose the right version

FluentLenium 3.x is still in development and includes latest enhancements and features, but Selenium 3 and Java 8 are required to run it.

Starting from FluentLenium 3.1.0 you can use all sparks of Java 8, including lambdas. It is a nice extension in comparison to Selenium 3 which is still basing on Guava objects. Please take a look on documentation to find await lambda usage example.

FluentLenium 1.x is in maintenance state, and no new feature will be added anymore. It requires Selenium 2 and Java 7, but can also be used with Java 8. Selenium 3 is not supported in this version though.

Quickstart with JUnit and AssertJ

• Basic FluentLenium test

import org.fluentlenium.adapter.junit.FluentTest;
import org.fluentlenium.core.hook.wait.Wait;
import org.junit.Test;

import java.util.concurrent.TimeUnit;

import static org.assertj.core.api.Assertions.assertThat;

@Wait
public class DuckDuckGoTest extends FluentTest {
    @Test
    public void titleOfDuckDuckGoShouldContainSearchQueryName() {
        goTo("https://duckduckgo.com");
        $("#search_form_input_homepage").fill().with("FluentLenium");
        $("#search_button_homepage").submit();
        await().atMost(5, TimeUnit.SECONDS).until(el("#search_form_homepage")).not().present();
        assertThat(window().title()).contains("FluentLenium");
    }
}

• A little bit more advanced version of the same FluentLenium test

import org.fluentlenium.adapter.junit.FluentTest;
import org.fluentlenium.core.annotation.Page;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class DuckDuckGoTest extends FluentTest {
    @Page
    DuckDuckMainPage duckDuckMainPage;

    @Test
    public void titleOfDuckDuckGoShouldContainSearchQueryName() {
        String searchPhrase = "searchPhrase";

        goTo(duckDuckMainPage)
                .typeSearchPhraseIn(searchPhrase)
                .submitSearchForm()
                .assertIsPhrasePresentInTheResults(searchPhrase);
    }
}

import static org.assertj.core.api.Assertions.assertThat;

import java.util.concurrent.TimeUnit;

import org.fluentlenium.core.FluentPage;
import org.fluentlenium.core.annotation.PageUrl;
import org.fluentlenium.core.domain.FluentWebElement;
import org.openqa.selenium.support.FindBy;

@PageUrl("https://duckduckgo.com")
public class DuckDuckMainPage extends FluentPage {
    private static final String SEARCH_FORM_HOMEPAGE = "#search_form_homepage";

    @FindBy(css = "#search_form_input_homepage")
    private FluentWebElement searchInput;

    @FindBy(css = "#search_button_homepage")
    private FluentWebElement searchButton;

    public DuckDuckMainPage typeSearchPhraseIn(String searchPhrase) {
        searchInput.write(searchPhrase);
        return this;
    }

    public DuckDuckMainPage submitSearchForm() {
        searchButton.submit();
        awaitUntilSearchFormDisappear();
        return this;
    }

    public void assertIsPhrasePresentInTheResults(String searchPhrase) {
        assertThat(window().title()).contains(searchPhrase);
    }

    private DuckDuckMainPage awaitUntilSearchFormDisappear() {
        await().atMost(5, TimeUnit.SECONDS).until(el(SEARCH_FORM_HOMEPAGE)).not().present();
        return this;
    }
}

• Run as a JUnit test.
