Selenium Cucumber Java BDD Framework 6 - Page Object Model | Step by Step

[@chicku975]

I had doubt regarding the logic behind the driver initialization in POM. I watched several Udemy videos from different Gurus but it did not get cleared. But after 1 year, I stumbled upon this video and my doubt got resolved within seconds after watching this video. Cannot believe how easily and detailed he explained the concept. Thanks a lot Raghav. Your contents are great. Keep doing what you do and keep helping the needy souls like us.

Why we are creating constructor ? Can you briefly explain the use case of constructor here Sir?

[@RaghavPal]

Hi Vipin, sure, Constructor is a function in a class having the same name as class and it is always called whenever the class is instantiated or an object is created for the class. Even if you do not explicitly create a constructor function, a default constructor is always present and is called, We make use of this feature to force user to send some input parameters when creating objects for a class by creating parameterized constructors

Thank you for the series of the videos on Selenium, cucmber, bdd. These video are very helpful and useful materials in learning the automation. I have couple of doubts. 1. If we need to run from the TestRunner class, do we need to include another glue code for the mapping of step definition with page file. 2. And could you please host few videos on database automation (DB testing). Thank you once again!

Hi, the same glue code should work, I will add videos on db automation testing

[@sumithra576]

Hello Raghav, I really liked the way how you organized the content and explained the concepts in lay man terms so any enthusiast can understand. Kudos to you on that. I was searching for the BDD framework content and came across your video playlist and I am glued to the content. When we run a feature file how did it know which java file to execute? We did not mention the dependency or sort of link any where. I see you some times comment the similar ones so the cucumber does not get confused which one to pick. Say for example all the .java are very different ones. then you cannot always comment the code and execute in a project right? So how do we handle such cases?

[@RaghavPal]

Hi Sumithra, glad to know you are enjoying this series. In general, we an provide the location of the glue code in Cucumber Runner class as you must have seen in the videos, It checks for the matching step definition with the steps of feature file and runs those functions.

[@mehmetakifgunder8499]

Hi Raghav. thank you very much. is the "pom" the best model in the testing field. in the example in this video, you used the functions and locators on the same page, but it is more advantageous to use the functions in common in the bdd system. how true is that? but now we use the common function and keep all the locators in a separate field. if there is a link to the latest example in this field, can you share it?

[@RaghavPal]

Hi Mehmet, POM design says to separate the objects & actions from the test scripts. So we need to keep our objects and methods separately in a diff class and we can create one class per page of the applications, Now in that class it depends if we also need to separate all object locators at the top OR keep all locators in a separate file and refer from there If we have lots of objects and we do not want to give access of class to everyone in QA team, then having a separate file for object locators is good option

what's the difference between 'Page factory' and 'By txt_username=By.is(.....);' in identifying the element.

[@RaghavPal]

Juli Let's explore the difference between Page Object Model (POM) and Page Factory in Selenium for identifying web elements: 1. Page Object Model (POM): - Design Pattern: POM creates an object repository for storing web elements. - Class Structure: Each web page is represented as a separate class file. - Advantages: - Easy Maintenance: When UI elements change, POM helps identify the specific page or screen to modify. - Code Reusability: Test code for one screen can be reused in other test cases. - Readability and Reliability: Independent Java files for each screen allow efficient code changes. - Implementation: - Define a separate Java class for each page/screen. - Include UI elements and operations specific to that page. - Use these classes to perform actions on the website under test. 2. Page Factory: - Class Provided by Selenium WebDriver: Page Factory supports Page Object Design patterns. - @FindBy Annotation: Instead of using `FindElement` or `FindElements`, Page Factory uses the `@FindBy` annotation. - Implementation: - Annotate web elements using `@FindBy`. - Initialize web elements using the `initElements` method. - Descriptive annotations make it easier to locate and declare web elements. In summary, POM focuses on organizing web elements into separate classes, while Page Factory simplifies element initialization using annotations. Both approaches enhance test case maintenance and readability. Choose the one that best suits your project needs --

[@tapaskhandai]

Hi Raghav, why we used login = new LoginPage(driver); in enter username and password method but not in click method below that?

this is to call the LoginPage class and send the driver parameter to its constructor and refer it with login, once this is done, now you can use login object to access LoginPage functions and properties

Hello Raghav, in the StepDef and Feature folders we have multiple Feature & stepDef file but when you when you do right click and select the run as cucumber feature then it execute the same stepDef file i mean hoe it binds the Feature file + step Def file.

Hi Ankit, it basically binds with the statements in given, when, then keywords and finds the corresponding func in any of the step def files. You can also add to check a specific file in the Cucumber Runner

[@praveenl4162]

Hi getting error compound classes not permitted please help (PAge object model)

[@RaghavPal]

Praveen Let's break down the problem step by step: Step 1: Understand the error message The error message "compound classes not permitted" typically occurs when Cucumber encounters multiple classes with the same name in the same package. This is not allowed in Java, as it can lead to ambiguity and conflicts. Step 2: Check your Page Object classes Review your Page Object classes and ensure that you don't have multiple classes with the same name in the same package. For example, if you have a `LoginPage.java` class, make sure you don't have another class with the same name in the same package. Step 3: Check for duplicate classes in your project Search your entire project for duplicate classes with the same name. You can use your IDE's search functionality or run a command like `find. -type f -name "*.java"` (on Linux/macOS) or `dir /s /b *.java` (on Windows) to search for Java files with the same name. Step 4: Check your step definition classes Verify that your step definition classes (e.g., `LoginSteps.java`) are not duplicating any Page Object class names. Step 5: Check your glue code If you're using a glue code file (e.g., `GlueCode.java`) to bind your step definitions to your Page Object classes, ensure that you're not accidentally creating duplicate classes or methods. Step 6: Review your Cucumber configuration Check your `cucumber.properties` or `cucumber.yml` file (depending on your Cucumber version) to ensure that you haven't accidentally configured Cucumber to scan multiple packages with duplicate class names. Step 7: Clean and rebuild your project Try cleaning and rebuilding your project to ensure that there are no stale class files or compilation issues. Step 8: Verify your Java and Cucumber versions Make sure you're using compatible versions of Java and Cucumber. You can check the Cucumber documentation for compatible versions. -

Where is hooks class in project structure?

[@RaghavPal]

The location of your hooks class in a Selenium Cucumber Java project can vary depending on your project structure and preferences. However, there are some common practices you can follow: General locations: 1. `src/test/java/hooks` package: This is a common convention where you have a dedicated package for all your hooks classes. Each file in this package can represent a specific type of hook (e.g., `BeforeAfterHooks.java`, `ScenarioHooks.java`). 2. `src/test/java/step_definitions` package: Some projects place hooks alongside step definition classes for convenience. While functional, it can mix concerns if all hooks are within the same package. 3. Project root: In smaller projects, hooks might be placed directly in the project root directory for quick access. However, this is not recommended for larger or more complex projects due to potential organization issues. Tips for choosing the right location: * Consider your project size and complexity: For larger projects, a dedicated `hooks` package promotes better organization. * Maintain consistency: Follow the existing structure in your project if already defined. * Clarity and maintainability: Choose a location that makes sense for your team and keeps your codebase clean and easy to navigate. Additional notes: * The hooks class itself is just a regular Java class with methods annotated with Cucumber hooks annotations like `@Before`, `@After`, `@BeforeStep`, etc. * The method names within the hooks class don't have specific requirements, but choose descriptive names that reflect their purpose (e.g., `setUpDriver`, `tearDownDriver`, `takeScreenshotOnFailedStep`).

Make sure that the WebDriver object is being passed correctly to the class where the findElement method is being called The WebDriver object is being instantiated in the wrong scope, for example, the object is being instantiated inside a method, but the findElement method is being called from outside of that method The web driver binary is not properly added to the project, please check if the web driver binary is added to the project and it's path is correctly referred in the code The compatibility between the version of Selenium, Cucumber and Java is not proper, please check if they are compatible with each other

[@RaghavPal]

Hi Archana The error message `java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.WebDriver.findElement(org.openqa.selenium.By)" because "this.driver" is null` means that the `driver` variable is null. This can happen if the `WebDriver` object has not been initialized yet. To fix this error, you need to initialize the `WebDriver` object before you try to use it. You can do this by creating a new `WebDriver` object in your `@BeforeClass` method. Here is an example of how to initialize the `WebDriver` object in your `@BeforeClass` method: ``` @BeforeClass public static void setUp() { System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver"); driver = new ChromeDriver(); } ``` Once you have initialized the `WebDriver` object, you can use it in your `@Test` methods. Here is an example of how to use the `WebDriver` object in your `@Test` method: ``` @Test public void testLogin() { driver.get("www.example.com"); LoginPage loginPage = new LoginPage(driver); loginPage.enterUserName("username"); loginPage.enterPassword("password"); loginPage.clickLoginButton(); } ``` If you are still getting this error after you have initialized the `WebDriver` object, then there may be another problem with your code. You can try to debug your code to find the problem.
