[JVM][Spring] Cucumber Spring and class configuration

[Piotr Klubinski]

I'm struggling with Cucumber and Spring configuration. I'm writing selenium framework using Page Object Pattern, with BrowserFactory.

When I use @ComponentScan, @Component and @Autowire annotations everything works fine, but when I want to create a bit more complicated bean with @Bean annotation (BrowserFactory which registers few browser drivers) in @Configuration class it does not work, during debug I'm getting nulls on every single variable I'm trying to Autowire.

I'm using Spring 4.2.4, all cucumber dependencies in version 1.2.4.

Config:

@Configuration 
public class AppConfig { 

 @Bean 
 @Scope("cucumber-glue") 
 public BrowserFactory browserFactory() { 
  BrowserFactory browserFactory = new BrowserFactory(); 
  browserFactory.registerBrowser(new ChromeBrowser()); 
  browserFactory.registerBrowser(new FirefoxBrowser()); 
 return browserFactory; }    

 @Bean(name = "loginPage") 
 @Scope("cucumber-glue") 
 public LoginPage loginPage() throws Exception { 
  return new LoginPage(); 
 }  

 @Bean(name = "login") 
 @Scope("cucumber-glue") 
 public Login login() { 
  return new Login(); } 
 }

POP:

public class LoginPage extends Page { 

 public LoginPage() throws Exception {
  super(); 
 } 
 ... 
}

Page:

public class Page { 

 @Autowired 
 private BrowserFactory browserFactory; 

 public Page() throws Exception{ 
 ... 
 } 
}

Login:

public class Login { 

 @Autowired 
 private LoginPage loginPage; 
 
 public Login(){
 } 
 ... 
}

Steps:

@ContextConfiguration(classes = {AppConfig.class}) 
public class LoginSteps { 

 @Autowired Login login; 

 public LoginSteps(){} 

 @Given("^an? (admin|user) logs in$") 
 public void adminLogsIn(Login.User user) throws Exception { 
  World.currentScenario().write("Logging in as " + user + "\n"); 
  login.as(user); 
 } 
}

Error:

cucumber.runtime.CucumberException: Error creating bean with name 'LoginSteps': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: Login LoginSteps.login; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'login': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private LoginPage Login.loginPage; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginPage' defined in AppConfig: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [LoginPage]: Factory method 'loginPage' threw exception; nested exception is java.lang.NullPointerException

And now for the fun part... BrowserFactory in World class is properly Autowired!!

World:

public class World { 

 @Autowired 
 private BrowserFactory browserFactory; 
 ... 
}
