Regression Testing Regression testing is the process of testing a software application after it has been modified or updated to ensure that the changes made do not negatively impact the functionality of the software. This type of testing is used to verify that any new changes or updates to the software do not introduce new bugs or cause existing features to malfunction. Regression testing is typically conducted on a regular basis, such as after each release or update, to ensure that the software remains stable and reliable. The goal of regression testing is to identify and fix any issues before they become major problems for users. What means by retesting? Retesting is the process of testing a software application again after it has been modified or updated. This type of testing is typically conducted after a bug or defect has been identified and fixed, in order to verify that the fix has resolved the issue and that the software is functioning correctly. Retesting is important because it helps to ensure that any bugs or defects that are identified are fully resolved and that the software is stable and reliable. Retesting can also be done after a software update or release to ensure that the new changes have not introduced any new issues or broken existing functionality. What is difference between retesting and regression testing? The main difference between retesting and regression testing is their focus and objectives. Retesting is focused on testing specific areas of the software that have been modified or updated after a bug or defect was identified and fixed, to ensure that the fix has resolved the issue and that the software is functioning correctly. Regression testing, on the other hand, is focused on testing the entire software application after it has been modified or updated to ensure that the changes made do not negatively impact the functionality of the software. This type of testing is used to verify that any new changes or updates to the software do not introduce new bugs or cause existing features to malfunction. In summary, retesting is focused on testing specific areas of the software to ensure that a fix has resolved an issue, while regression testing is focused on testing the entire software application to ensure that changes have not negatively impacted the functionality.

We are listing 25 interview questions in this post if any important questions are not in the below list please add same in the comment What is Selenium and why is it used for web automation? Selenium is a suite of software tools that is used for automating web browsers. It allows developers and testers to automate web applications in a variety of languages and on a variety of platforms. Selenium is used for web automation because it allows for the creation of automated tests that can be run against web applications to ensure that they are functioning correctly. These tests can be run repeatedly, which helps to ensure that the application is stable and reliable over time. Additionally, Selenium can be used to automate repetitive tasks, such as filling out forms or navigating through a website, which can save time and improve efficiency. What are the different components of the Selenium suite? The Selenium suite is made up of several different components, each serving a specific purpose: Selenium WebDriver: This is the core component of the Selenium suite and is used to interact with web browsers. It allows developers and testers to write scripts that can automate web browsers and interact with web applications. Selenium RC (Remote Control): This component is used to run Selenium WebDriver scripts on a remote machine. It allows for parallel testing by running tests on different machines simultaneously. Selenium Grid: This component allows for the distribution of test execution across multiple machines and different browsers, it allows to perform of parallel testing. Selenium IDE (Integrated Development Environment): This is a Firefox plug-in that allows users to record and playback tests. It is primarily used for creating simple test scripts and for learning Selenium. Selenium WebDriverJS: This is a JavaScript implementation of Selenium WebDriver, it allows developers to write tests using JavaScript. Selenium Wire: It allows to intercept and inspect network traffic, it can be used to debug network issues and analyze the performance of web pages. Selenium Server: This component is used to run Selenium WebDriver scripts on a remote machine, it allows to run of Selenium RC scripts and Selenium Grid. How does Selenium WebDriver interact with web browsers? Selenium WebDriver interacts with web browsers by sending commands to the browser through a driver. The driver is a specific implementation of the WebDriver API for a particular browser. Each browser has a different driver, for example, there is a driver for Chrome, Firefox, and Internet Explorer. Selenium WebDriver sends commands to the browser driver, which then translates those commands into actions that the browser can understand and execute. For example, when Selenium WebDriver sends the command to navigate to a specific website, the browser driver will translate that command into the appropriate actions for the browser, such as opening a new tab, entering the website’s URL, and loading the page. Selenium WebDriver also receives information from the browser driver, such as the page’s source code and the current state of the browser. This information can be used to verify that the browser is in the expected state or to extract information from the page. In summary, Selenium WebDriver uses a browser driver to interact with web browsers. It sends commands to the browser driver which in turn translates them into actions that the browser can understand and execute. And it also receives information from the browser driver to verify the state of the browser or extract information from the page. What are the advantages of using Selenium over other web automation tools? There are several advantages of using Selenium over other web automation tools: Cross-browser compatibility: Selenium supports a wide range of browsers, including Chrome, Firefox, Internet Explorer, Edge, and Safari, so it can be used to automate tests on different browsers. Language support: Selenium supports a variety of programming languages, such as Java, C#, Python, Ruby, JavaScript, and Perl, which allows developers and testers to use the language they are most comfortable with. Open-source: Selenium is an open-source tool which means it’s free to use and developers have access to the source code and can customize it to fit their needs. Large community: Selenium has a large and active community of developers, which means that there are a lot of resources available and that any issues or bugs are likely to be resolved quickly. Integrations: Selenium can be integrated with other tools, such as TestNG and JUnit, for test case management and reporting. Flexibility: Selenium allows for a variety of testing strategies, such as unit testing, integration testing, and end-to-end testing, which makes it a versatile tool for different types of testing needs. Scalability: Selenium Grid allows for the distribution of test execution across multiple machines and different browsers, making it easy to scale up test automation efforts. Support for mobile testing: Selenium can be used to automate tests on mobile devices through the use of additional tools like Appium. In summary, Selenium offers several advantages over other web automation tools, including cross-browser compatibility, language support, being open-source, having a large community, the ability to integrate with other tools, flexibility, scalability, and support for mobile testing. Can you explain the concept of Locators in Selenium and the types of locators available? In Selenium, locators are used to identifying and locate elements on a web page. They are used to specify the element(s) that a test script should interact with. Selenium supports several types of locators, each with its own strengths and weaknesses. ID: ID is the most efficient and reliable way to locate an element. It uses the “id” attribute of an element to locate it. For example, if the element has an id attribute of “username”, then the locator would be “id=username”. Name: It uses the “name” attribute of an element to locate it. For example, if the element has a name attribute of “username”, then the locator would be “name=username”. Class Name: It uses the “class” attribute of an element to locate it. For example, if the element has
