Spring dependency integration with Selenium

Question

I don't know why, but Spring don't @Autowired my dependencies and I always get NullPoionterException. I get exception in initializeDriver method on chromeOptions.addArguments("test-type");. I'm creating WebDriver using factory pattern like this.

public abstract class DriverManager {

    protected WebDriver webDriver;
    protected abstract void initializeDriver();

    public void quitDriver() {
        if (webDriver != null) {
            webDriver.quit();
            webDriver = null;
        }
    }

    public WebDriver getWebDriver() {
        return webDriver;
    }
}
@Component
public class ChromeDriverManager extends DriverManager {

    @Autowired
    private DesiredCapabilities desiredCapabilities;

    @Autowired
    private ChromeOptions chromeOptions;

    @Autowired
    private BeanFactory beanFactory;

    @Autowired
    private LoggingPreferences loggingPreferences;


    protected void initializeDriver() {
        desiredCapabilities = DesiredCapabilities.chrome();
        chromeOptions.addArguments("test-type");
        chromeOptions.addArguments("--disable-extensions");
        chromeOptions.addArguments("-incognito");
        desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);

        loggingPreferences = new LoggingPreferences();
        loggingPreferences.enable(LogType.BROWSER, Level.ALL);
        desiredCapabilities.setCapability(CapabilityType.LOGGING_PREFS, loggingPreferences);
        webDriver = beanFactory.getBean(ChromeDriver.class, desiredCapabilities);
    }
}

@Component
public class DriverManagerFactory {

    @Autowired
    @Qualifier("ChromeDriverManager")
    private DriverManager chromeDriverManager;

    public DriverManager getManager(Browser browser) {
        DriverManager driverManager;
        switch (browser) {
            case CH:
                chromeDriverManager.initializeDriver();
                driverManager = chromeDriverManager;
                break;
            default:
                //todo rest of browsers
                driverManager = null;
        }
        return driverManager;
    }
}

@Configuration
@ComponentScan(basePackages = "tmp")
public class AppConfig {

    @Bean
    @Lazy
    public ChromeDriver chromeDriver(DesiredCapabilities desiredCapabilities) {
        System.setProperty("webdriver.chrome.driver", "C:\\ATF\\drivers\\chromedriver.exe");
        return new ChromeDriver(desiredCapabilities);
    }

    @Bean
    public DesiredCapabilities desiredCapabilities() {
        return new DesiredCapabilities();
    }

    @Bean
    public ChromeOptions chromeOptions() {
        return new ChromeOptions();
    }

    @Bean
    public LoggingPreferences loggingPreferences() {
        return new LoggingPreferences();
    }
}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class)
public class runChrome {

    @Autowired
    DriverManagerFactory driverManagerFactory;

    DriverManager driverManager;

    @Before
    public void beforeTest() {
        driverManager = driverManagerFactory.getManager(Browser.CH);
    }


    @Test
    public void run() {
        driverManager.getWebDriver().get("http://www.google.com");
    }
}

Did I need some annotation on my ChromeDriverManager class or what? I don't get it. My first approach was without factory pattern and all work fine. But I do all things in my test class and it look like this.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class)
public class runChrome {

    @Autowired
    private BeanFactory beanFactory;

    @Autowired
    private DesiredCapabilities desiredCapabilities;

    @Autowired
    private LoggingPreferences loggingPreferences;

    @Autowired
    private ChromeOptions chromeOptions;

    @Test
    public void run() {
        desiredCapabilities = DesiredCapabilities.chrome();
        chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("test-type");
        chromeOptions.addArguments("--disable-extensions");
        chromeOptions.addArguments("-incognito");
        desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);

        loggingPreferences = new LoggingPreferences();
        loggingPreferences.enable(LogType.BROWSER, Level.ALL);
        desiredCapabilities.setCapability(CapabilityType.LOGGING_PREFS, loggingPreferences);
        ChromeDriver chromeDriver = beanFactory.getBean(ChromeDriver.class, desiredCapabilities);
        chromeDriver.get("http://www.google.com");
    }
}

My application config don't change. I use the same in both scenarios. Edit: I have edited my code to suggestions. But still I get this ugly exception.

Answer 1

Couple of points

1. You need to have @Component (or anything equivalent) on ChromeDriverManager class. Without this none of your fields will be Autowired since it will not be scanned at all.
2. In your DriverManagerFactory class you are doing new ChromeDriverManager() if you create instance using new then you lose spring autowiring capabilities and all the fileds inside this new object you created will be null(even if you put @Component on ChromeDriverManager)
   So you need to Autowire ChromeDriverManager in your DriverManagerFactory class. And of course make DriverManagerFactory class a bean using @Component(similar to point 1)
