What are the types of xpath?
1) Absolute XPath . 2) Relative XPath . Absolute XPath : It is the direct way to find the element, but the disadvantage of the absolute XPath is that if there are any changes made in the path of the element then that XPath gets failed. The key characteristic of XPath is that it begins with the single forward slash(/) ,which means you can select the element from the root node. Relative xpath: For Relative Xpath the path starts from the middle of the HTML DOM structure. It starts with the double forward slash (//), which means it can search the element anywhere at the webpage.

How to connect a Database in selenium?
As we all know Selenium WebDriver is a tool to automate User Interface. We could only interact with Browser using Selenium WebDriver. We use JDBC Driver to connect the Database in Selenium (While using Java Programming Language).
How to achieve Database testing in Selenium?
As we all know Selenium WebDriver is a tool to automate User Interface. We could only interact with Browser using Selenium WebDriver. Sometimes, we may face a situation to get the data from the Database or to modify (update/delete) the data from the Database. If we plan to automate anything outside the vicinity of a browser, then we need to use other tools to achieve our task. To achieve the Database connection and work on it, we need to use JDBC API Driver. The Java Database Connectivity (JDBC) API provides universal data access from the Java programming language. Using the JDBC API, you can access virtually any data source, from relational databases to spreadsheets and flat files. It lets the user connect and interact with the Database and fetch the data based on the queries we use in the automation script. JDBC is a SQL level API that allows us to execute SQL statements. It creates a connectivity between Java Programming Language and the database. Using JDBC Driver we could do the following i. Establish a Database connection ii. Send SQL Queries to the Database iii. Process the results
What is the difference between Assert and Verify in Selenium?
Assert: In simple words, if the assert condition is true then the program control will execute the next test step but if the condition is false, the execution will stop and further test step will not be executed. To overcome this issue we use a try-catch block. Verify: In simple words, there won't be any halt in the test execution even though the verify condition is true or false.Mostly, the Verify command is used to check non-critical things. In such cases where we move forward even though the end result of the check value is failed.eg . if else condition
How can you use the Recovery Scenario in Selenium WebDriver?
By using "Try Catch Block" within Selenium WebDriver Java tests.

What is Continuous Integration?
Continuous Integration is abbreviated as CI. Continuous Integration is a development practice which aims to make sure the correctness of a software. After each commit, a suite of tests run automatically and test the software to ensure whether the software is running without any breaks. If any test fails, we will get immediate feedback say "build is broken". In simple words, continuous integration is a process of verifying the correctness of a software. Some of the continuous integration tools are Jenkins, TeamCity, Bamboo, Travis, Circle Ci, Bitbucket.

What are the types of waits available in Selenium WebDriver
Implicit Waits - The implicit wait tells to the WebDriver to wait for certain amount of time before it throws an exception Explicit Waits -to wait for a certain condition to occur before proceeding further in the code. Fluent Waits -We use FluentWait commands mainly when we have web elements which sometimes visible in few seconds and sometimes take more time than usual
What are the types of wait available in Selenium?
Implicit Waits -is applicable for the entire page. The driver will wait until the required time to make sure that all the pages are loaded, before it throws exception. Explicit Waits -WebDriverWait is applied on a certain element with defined expected condition and time. This wait is only applied to the specified element eg. advertisement/third party pop up . This wait can also throw an exception when an element is not found.driver will check the element in every second. Polling - we can supply how many interval time Fluent Waits - FluentWait can define the maximum amount of time to wait for a specific condition and frequency with which to check the condition before throwing an "ElementNotVisibleException" exception.
How you build Object Repository in your project?
In QTP, there is an Object Repository concept. When a user records a test, the objects and its properties are captured by default in an Object Repository. QTP uses this Object Repository to play back the scripts. Coming to Selenium, there is no default Object Repository concept. It doesn't mean that there is no Object Repository in Selenium. Even though there is no default one still we could create our own. In Selenium, we call objects as locators (such as ID, Name, Class Name, Tag Name, Link Text, Partial Link Text, XPath, and CSS). Object repository is a collection of objects. One of the ways to create Object Repository is to place all the locators in a separate file (i.e., properties file). But the best way is to use Page Object Model. In the Page Object Model Design Pattern, each web page is represented as a class. All the objects related to a particular page of a web application are stored in a class.
How To Perform Drag And Drop Action in Selenium WebDriver?
In some applications, we may face a situation to automate drag and drop an item from one location to another location. We could not achieve these using basic elements.

What is Object Repository? How can we create Object Repository in Selenium?
Object Repository is a term used to refer to the collection of web elements belonging to Application Under Test (AUT) along with their locator values. Thus, whenever the element is required within the script, the locator value can be populated from the Object Repository. Object Repository is used to store locators in a centralized location instead of hardcoding them within the scripts. In Selenium, objects can be stored in an excel sheet which can be populated inside the script whenever required.
What is Object Repository in Selenium WebDriver?
Object Repository is used to store element locator values in a centralized location instead of hard coding them within the scripts. We do create a property file (.properties) to store all the element locators and these property files act as an object repository in Selenium WebDriver.

What is Selenium?
Selenium is the most popular browser automation tool. There are other ways, but the best way to use Selenium is via WebDriver, a powerful API that builds on top of Selenium and makes calls to a browser to automate it, carrying out actions such as "open this web page", "move over this element on the page", "click this link", "see whether the link opens this URL", etc. This is ideal for running automated tests. (Selenium is an open source (free) automated testing suite to test web applications. It supports different platforms and browsers. It mainly used for Functional Testing and regression testing. Selenium is a set of different software tools. Each tool has a different approach in supporting web based automation testing.Selenium is a browser automation tool, commonly used for writing end-to-end tests of web applications. A browser automation tool does exactly what you would expect: automate the control of a browser so that repetitive tasks can be automated. At a very high level, Selenium is a suite of three tools.Selenium-WebDriver makes direct calls to the browser using each browser's native support for automation. Since there are so many browsers & so many programming languages there is need for common specification which will be provided by WebDriver API. Each browser has to implement this API which is called as Remote WebDriver or Remote WebDriver Server.)
