selenium-jupiter: A Java repository from clobob

Selenium-Jupiter is an open-source Java library that implements a JUnit 5 extension for developing Selenium WebDriver tests. Selenium-Jupiter uses several features of the Jupiter extension (such as parameters resolution, test templates, or conditional test execution). Thanks to this, the resulting Selenium-Jupiter tests follow a minimalist approach (i.e., the required boilerplate code for WebDriver is reduced) while providing a wide range of advanced features for end-to-end testing.

Documentation

You can find the complete documentation of Selenium-Jupiter here. This site contains all the features, examples, and configuration capabilities of Selenium-Jupiter.

Local browsers

Selenium-Jupiter can be used to control local browsers programmatically using Selenium WebDriver. To do that, we need to specify the flavor of the browser to be used by declaring WebDriver parameters in tests or constructors. For instance, we declare a ChromeDriver parameter to use Chrome, FirefoxDriver for Firefox, and so on. For instance:

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

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.openqa.selenium.chrome.ChromeDriver;

import io.github.bonigarcia.seljup.SeleniumJupiter;

@ExtendWith(SeleniumJupiter.class)
class ChromeTest {

    @Test
    void test(ChromeDriver driver) {
        driver.get("https://bonigarcia.dev/selenium-webdriver-java/");
        assertThat(driver.getTitle()).contains("Selenium WebDriver");
    }

}

Internally, Selenium-Jupiter uses WebDriverManager to manage the WebDriver binaries (i.e., chromedriver, geckodriver, etc.) required to use local browsers.

Browsers in Docker containers

Selenium-Jupiter allows using browsers in Docker containers very easily. The only requirement is to get installed Docker Engine in the machine running the tests. The following example shows a test using this feature. Internally, it pulls the image from Docker Hub, starts the container, and instantiates the WebDriver object to use it. This example also enables the recording of the browser session and remote access using noVNC:

import static io.github.bonigarcia.seljup.BrowserType.CHROME;
import static org.assertj.core.api.Assertions.assertThat;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.openqa.selenium.WebDriver;

import io.github.bonigarcia.seljup.DockerBrowser;
import io.github.bonigarcia.seljup.SeleniumJupiter;

@ExtendWith(SeleniumJupiter.class)
class DockerChromeTest {

    @Test
    void testChrome(@DockerBrowser(type = CHROME) WebDriver driver) {
        driver.get("https://bonigarcia.dev/selenium-webdriver-java/");
        assertThat(driver.getTitle()).contains("Selenium WebDriver");
    }

}

Conditional tests

Selenium-Jupiter provides the class-level annotation @EnabledIfBrowserAvailable to skip tests conditionally depending on the availability of local browsers. For example:

import static io.github.bonigarcia.seljup.Browser.SAFARI;
import static org.assertj.core.api.Assertions.assertThat;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.openqa.selenium.safari.SafariDriver;

import io.github.bonigarcia.seljup.EnabledIfBrowserAvailable;
import io.github.bonigarcia.seljup.SeleniumJupiter;

@EnabledIfBrowserAvailable(SAFARI)
@ExtendWith(SeleniumJupiter.class)
class SafariTest {

    @Test
    void test(SafariDriver driver) {
        driver.get("https://bonigarcia.dev/selenium-webdriver-java/");
        assertThat(driver.getTitle()).contains("Selenium WebDriver");
    }

}

Test templates

Test templates are a special kind of test in which the same test logic is executed several times according to some custom data. In Selenium-Jupiter, the data to feed a test template is referred to as the browser scenario (a JSON file by default).

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

import org.junit.jupiter.api.TestTemplate;
import org.junit.jupiter.api.extension.ExtendWith;
import org.openqa.selenium.WebDriver;

import io.github.bonigarcia.seljup.SeleniumJupiter;

@ExtendWith(SeleniumJupiter.class)
class TemplateTest {

    @TestTemplate
    void templateTest(WebDriver driver) {
        driver.get("https://bonigarcia.dev/selenium-webdriver-java/");
        assertThat(driver.getTitle()).contains("Selenium WebDriver");
    }

}

... and the browser scenario is:

{
   "browsers": [
      [
         {
            "type": "chrome-in-docker",
            "version": "latest"
         }
      ],
      [
         {
            "type": "chrome-in-docker",
            "version": "latest-1"
         }
      ],
      [
         {
            "type": "chrome-in-docker",
            "version": "beta"
         }
      ],
      [
         {
            "type": "chrome-in-docker",
            "version": "dev"
         }
      ]
   ]
}
