Quick Notes on Selenium IQs

What is method overload and method override?

Method Overload:method overload means methods contain with same name and difference in the parameters

This difference may be in the 

-> sequence of the parameters

-> number of the parameters

-> type of the parameters

Method Override: Method Override means methods with same name and same parameters. This override performs in parent and child classes

What is a static keyword in Java?

If applies static to the member of a class. You can directly access that with the classname without creating any object.

• The value of the  static variable is shared by all objects of a class means same set of copy available to all the objects.

What is final keyword in Java?

Final means fixed. No changes can be happened on it. If applies final

    -> to a variable then, that variable value can not be changed.

    -> to a method then, that method can not be override

    -> to a class then that class can not be inherited.

What are the Access Modifiers?

Access Modifiers are:

1. public

2. private

3. default

4. protected

-> public means that member of a class can be visible and accessed anywhere in the project.

-> private means that member can be visible and accessed with in a method or class.

-> default means that member can be visible and accessed with in a package. If no access modifier is used, it considers as default

-> protected means that member can be visible and accessed with in a package and in child classes of another package.

What is Selenium?

Selenium is a automation tool which is used to automate the web applications.

Advantages of Selenium?

1. Selenium is an Open-Source

2. Selenium supports multiple languages like Java, c#, Python, Ruby, Perl etc.,

3. We can write the automation scripts in multiple browsers like chrome, firefox, IE, Microsoft Edge etc.,

4. Selenium supports multiple Operating Systems Windows, Linux, Mac etc.,

5. Supports Android and iOS

What is a WebDriver?

WebDriver is an Interface, it is implemented by respective Browser Drivers like ChromeDriver, FirefoxDriver etc.,

Write a simple Selenium Script or Code?

System.setProperties("webdriver.chrome.driver","Path of the Driver File");

WebDriver driver=new ChromeDriver();

driver.get("URL");

What are different Locators in Selenium?

Locator: Locator means an address of an WebElement. We have Locators in Selenium like

1. id

2. name

3. className

4. tagName

5. linkText

6. partialLinkText

7. xpath

8. cssSelector

What is absolute xpath and relative xpath?

absolute xpath starts with '/' and it identifies the element from route node to child node.

relative xpath starts with '//' and it identifies the element directly where it present in the HTML DOM.

Note: / -> single forward slash, // -> double forward slashes

How to write xpath?

We can write the xpath using tagName, attribute and values like

//tagName(@attribute='value')

Also we can write xpath with

1. text() method

2. contains() method

3. xpath axes like parent, ancestor, preceding-sibling and forwarding-sibling etc.,

What is a Page Object?

A Page Object is class which is created for each and every page of an application.

This class contains all the WebElements of the page and getter methods for respective webElements.

What is the PageFacory?

PageFacory is a class which is used to initialize the PageObject.

Diference between findElement and findElements()?

findElement() is used for Single elements and return type is WebElement.

findElements() is used for List of WebElements and return type is List<WebElement>.

What are the waits in Selenium?

Selenium provides waits like

1. implicitwait

2. explicitwait

3. fluentwait

What is the difference between implicit wait and explicit wait?

implicit wait is used to provide waiting time for all the WebElements

explicit wait is used to provide the waiting time for a specific condition or WebElement.

Write a code for implicit wait?

driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS) ;

Write a code for explicit wait?

WebDriverWait wait = new WebDriverWait(driver,30);

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("locator")));

How to enter the data into the textbox?

using sendKeys() method of selenium library, we can enter the data.

How to click on a button?

using click() method, we can click on a button

How to get the text of a WebElement?

using getText(), we can get the Text.

How to initialize the webdriver?

WebDriver driver =new FirefoxDriver();

Here, we create the object for the class 'FirefoxDriver' and store it in reference variable of the Webdriver Interface.

How to launch a browser and pass the URL?

    1. First, we need to set the property for the driver like

    System.setProperty("webdriver.gecho.driver", "path of the driver file");

    2. Intialize the driver like

    WebDriver driver =new FirefoxDriver();

    3. Use the get() method to pass the URL like

    driver.get("URL");

what is the difference between quit() and close()?

quit() method closes all the window instances opened by the driver

close() method closes only current window instance.

How to handle/select dropdown element in the selenium?

We can handle dropdown element using Select class. The class contains the methods like

selectByIndex()

selectByValue()

selecByVisibleText()

Example: 

Select select=new Select(driver.findElement(By.xpath("locator")));

select.selectByVisibleText();

How to do mouse over action and click()?

We can take the help of Actions class to this. 

1st create an object for actions class

2nd Perform the mouse hover action using moveToElement method.

3rd click on the link using click method.

Example:

Actions action = new Actions(driver);

action.moveToElement(driver.findElement(By.xpath("<xpath>"))).perform();

action.click().build().perform()

How to Handle multiple Windows in Selenium?

getWindowHandle(), getWindowHandles() and switchTo() methods help to work with multiple windows.

All Opened window Ids get and store in Set reference variable and switch them with switchTo() method.

How to take a screenshot in Selenium?

We can take the help of "TakesScreenshot" Interface. This interface has the method "getScreenshotAs()". Using this, we can  take the screenshot and save it in a file.

Code Snippet:

    TakesScreenshot scrShot =((TakesScreenshot)webdriver);

    File SrcFile=scrShot.getScreenshotAs(OutputType.FILE);

    FileUtils.copyFile(SrcFile, "C:/Test.png");

What is textng.xml file format?

@BeforeSuite

   @BeforeTest

      @BeforeClass

         @BeforeMethod

           @Test

         @AfterMethod

      @AfterClass

   @AfterTest

@AfterSuite

@beforesuite -> this annotation will call before executing all the tests

@beforetest -> this annotation will call before executing all test cases

@beforeclass -> this annotation will call before executing all test cases in a class

@beforemethod -> this annotation will call before executing each and every test case

@Test -> it represents a Test Case

@aftermethod -> this annotation will call after executing each and every test case

@afterclass -> this annotation will call after executing all test cases in a class

@aftertest -> this annotation will call after executing all test cases

@aftersuite -> this annotation will call after executing all the tests

What is an Assertion?

Assertion is used for validation. We use Assert class from testng library to this validations. It has methods like assertEquals(), assertTrue(), assertFalse()

How to run only smoke testcases?

We can set the tag in the feature file and it pass in the TestRunner file.

What are the dependecies required for Cucumber BDD Framework?

Along with selenium-java and testng, also require

cucumber-testng

cucumber-java

What are CucumberOptions in TestRunner File?

We have CucumberOptions like

1. features

2. glue

3. tags

4. format

5. dryRun

6. monochrome

7. strict

Explanation:

features option is for setting up the path of the feature files

glue option is for setting up the path of the stepDefinition files

tags is to instruct what tag from feature file to execute

format is to set which report format to be generate after execution

dryRun to check all feature steps has respective matched Step Definition. Default Value is False

monochrome to display console output in readable way. Default Value is False

strict is to fails the execution if there are undefined or pending steps. Default Value is False

What are the Hooks in Cucumber?

@Before and @After

-> Before executes before executing all the steps

-> After executes after executing all the steps

What is the framework you are using and Can you explain briefly?

I am working on BDD Framework with cucumber. It contains the components like

1. feature files

2. stepdefinition files

3. pageobjects

4. testrunner

5. WebDriverManager

6. utility

7. testdata

8. properties file

9. target

10. config folder

11. pom.xml

What is the feature file?

feature file contains all the scenarios to be execute. 

One feature file contains multiple scenarios

One scenario contains multiple steps

We write scenarios and steps in Gherkin Language

What are the Keywords use in feature file?

We use Gherkin Keywords like

feature at feature level

scenario and scenario outline at scenario level

Given, When, Then, And, But at step level

What is deference between scenario and scenario outline?

we do not pass the testdata in scenario but we can pass testdata in "scenario outline" using "Example" keyword.

Can you write BDD steps for Gmail login Functionality in the feature file?

Yes I write.

with Scenario:

Feature: Application Login

Scenario: Verify Login Functionality

Given I Open The Gmail

When I Entered The Username "abc@gmail.com" and password "12345"

And I Click On Login Button

Then I See Gmail Home Page

or 

with Scenario Outline:

Feature: Application Login

Scenario Outline: Verify Login Functionality

Given I Open The Gmail

When I Entered The <username> and <password>

And I Click On Login Button

Then I See Gmail Home Page

Examples:

      | username | password |

Type Casting

 Type Casting:

The process of converting value of one Datatype to another Datatype. Two ways of Casting:

Widening:  Converting a smaller datatype to higher datatype is called widening.

byte-> short -> char -> int -> long -> float -> double

widening happens automatically and it is safe operation. We also call widening as implicit casting.

              Ex:       int n=10;

                          float  x=n;

Narrowing: Converting a higher datatype to smaller datatype is called narrowing.

double -> float -> long -> int -> char -> short -> byte

narrowing happens manually and it is not safe operation. We also call narrowing as explicit casting.

              Ex:       float     n=10.2f;

                          int x=(int)n                  Output: 10

Manual Testing Questions

What is Smoke Testing?

Smoke Testing: This is build acceptance Testing performed after build is released to the Testing. This Testing is done to check the major functionalities are working fine or not.

What is Sanity Testing?

Sanity Testing: This is build acceptance Testing performed after build is released to the Production. This Testing is done to check the major functionalities are working fine or not.

What is Re-Testing?

Retesting: Retesting is performed after Defect is fixed to verify whether fix is working fine

What is Regression Testing?

Regression: Regression is performed in 3 ways to make sure existing functionality is not disturbed during the changes.

1. Whenever new build is released

2. Whenever a defect is fixed

3. Whenever environment changes are happened

What is UAT?

UAT (User acceptance Testing): UAT is performed verify whether build is acceptable to customer before releasing to the production. We have 2 types of UAT testing:

1. Alpha - Testing

2. Beta - Testing

Alpha-Testing is performed at development site in the presence of the customer

Beta-Testing is performed at production site in the presence of the customer

What is Defect Life Cycle:

Defect Life Cycle: We can say Defect Life Cycle means "the travel of the defect from Open status to Closed status"

There different phases of a Defect:

1. Open

2. In progress

3. Fixed

4. Resolved

5. Closed

6. Reopened

7. Invalid

8. Deferred

-> Whenever a Tester raised the defect, the status of the defect is 'open'.

-> It is moved to "Inprogress" when Developer accepts the defect as Bug

-> When developer gives the fix for the defect then, the status is moved to 'Fixed'

-> Once the defect is fixed, Tester does Retesting. If functionality is working as expected, the status is moved to 'Resolved'

-> If the Functionality is not working as expected, then the status of the defect is moved to 'Re-Opened'

-> All Resolved Defects are moved to the 'Closed' status by the Test Lead.

-> Whenever defect is raised and developer thinks it is working fine. He changes the defect status to 'Invalid'

-> If there are any minor defects and those are not required to fix in the current release the Defect status is moved to 'Deferred' 

What is the deferred status?

If there are any minor defects and those are not required to fix in the current release then, the Defect status is moved to 'Deferred'.

What is Priority and its Levels?

Priority tells How urgency, the defect need to be fixed. It is Client Point of View.

Priority Levels can be:

1. Blocker

2. Critical

3. Major

4. Medium

5. Minor

6. Low

What is Severity and its Levels?

Severity tells the impact of the defect on the application. 

Deferent Severity Levels are:

1. Blocker

2. Critical

3. Major

4. Medium

5. Minor

6. Low
