Selenium is a portable software-testing framework for web applications. Selenium provides a playback tool for authoring functional tests without the need to learn a test scripting language. It also provides a test domain-specific language (Selenese) to write tests in a number of popular programming languages, including C#, Groovy, Java, Perl, PHP, Python, Ruby and Scala. Selenium tests can be run against most modern web browsers. Selenium is an open source project, hosted at Google Code.
The Selenium architecture is based on a client-server model. The Selenium client library is used to create browser-based automated tests. These tests are then run on a Selenium server, which translates the tests into commands that are sent to a browser. The browser then executes the commands and returns the results to the server.
What are the 4 major components of Selenium WebDriver architecture?
Selenium Language Bindings:
Selenium provides language bindings for multiple programming languages. This allows developers to write their tests in their preferred language. Some of the language bindings supported by Selenium include Java, C#, Python, Ruby, and JavaScript.
JSON Wire Protocol:
The JSON Wire Protocol is a communication protocol used by the WebDriver to interact with the browser. It uses a JSON object to send commands to the browser and receive responses.
Browser Drivers:
Browser drivers are programs that act as a bridge between the WebDriver and the browser. They provide a way for the WebDriver to interact with the browser. Some of the browser drivers supported by Selenium include ChromeDriver, FirefoxDriver, and SafariDriver.
Real Browsers:
Real browsers are actual web browsers, such as Google Chrome, Mozilla Firefox, and Microsoft Edge. The WebDriver can interact with these browsers to execute tests and perform actions on web pages.
The Selenium 3 architecture includes the JSON Wire Protocol. However, Selenium 4 does not include the JSON Wire Protocol. That’s the contrast between Selenium 3 and Selenium 4. JSON stands for JavaScript Object Notation.
Can you explain about Selenium architecture how Selenium works internally
Selenium provides browser-specific drivers that allow it to securely interact with each browser without revealing the internal logic of that browser’s functionality. This allows Selenium to support a wide range of browsers while still providing a consistent interface to users.
Selenium 4 architecture is based on communication between the client and server. The client has two parts: Selenium Client and WebDriver Language Bindings. Browser Drivers are the server. Selenium Client sends out a request to perform a command.
How many types of API are there in Selenium?
Log4J is a Java-based logging utility. It has two APIs: Log4J 1 and Log4J 2. Log4J 1 is the original API, while Log4J 2 is a complete rewrite of the original API. Both APIs are compatible with each other.
TestNG is a powerful testing framework that is widely used for the Selenium WebDriver. It includes data-driven functionality, which makes it an essential tool for testers. TestNG makes it easy to create and run tests, and it provides a wide range of features that make it a valuable tool for any tester.
What is Selenium 3 vs 4 architecture?
The first difference between Selenium 3 & 4 will be on the basis of the extension of Chrome Driver. Chrome Driver is extended to the Remote Web Driver in Selenium 3. Whereas, in the case of Selenium 4, the Chrome Driver Class is extended to Chrome Driver.
An automation framework is a platform that enables efficient design and development of automated test scripts, and reliable analysis of issues for the system under test. It is developed by integrating various hardware and software resources, and various tools and services, based on a qualified set of set of assumptions.
Is Selenium a framework or API
Selenium 20 is the successor of Selenium Remote Control. It is a collection of language-specific bindings that drive a browser how it has to be driven. It consists of API, Library, Driver, and Framework that work together to enable test execution.
Selenium has four main components:
Selenium IDE – This is used for record-and-playback of user interactions with the web browser.
Selenium WebDriver – This is used for programmatic interaction with the web browser.
Selenium RC – This is used for running Selenium tests on a remote machine.
Selenium Grid – This is used for running Selenium tests in a distributed environment.
How can I explain my framework in Selenium?
Selenium is an open-source software framework that automates the testing of web applications. It is designed to reduce the time and cost of test cycles, saving money and resources. Selenium is written in Java and supports a variety of programming languages, including Python, C++, and Perl.
Maven is a great tool for managing Java projects. It can help simplify the build process and manage dependencies. It is also widely used to manage the lifecycle of a project.
What is TestNG architecture
TestNG was designed to cover a wider range of test categories: unit, functional, end-to-end,integration, etc., with a wider range of tools and plug-ins for IDE’s and build tools.
There are different types of drivers available in Selenium WebDriver, each one offering different features.
ChromeDriver is used to execute Selenium Automation Scripts on Chrome Browser.
FirefoxDriver is used to execute Selenium Automation Scripts on Firefox Browser.
InternetExplorerDriver is used to execute Selenium Automation Scripts on Internet Explorer Browser.
SafariDriver is used to execute Selenium Automation Scripts on Safari Browser.
OperaDriver is used to execute Selenium Automation Scripts on Opera Browser.
EdgeDriver is used to execute Selenium Automation Scripts on Edge Browser.
EventFiringWebDriver is used to execute Selenium Automation Scripts by firing events.
RemoteWebDriver is used to execute Selenium Automation Scripts on a remote machine.
What is JSON protocol in Selenium?
JSONWP is a transport mechanism created by WebDriver developers to expose a RESTful API. This wire protocol is a specific set of predefined, standardized endpoints. It is based on the JSON format and enables communication between different webdriver-based tools.
Each API protocol has its own strengths and weaknesses. REST is best suited for simple data retrieval, while RPC is better for more complex data manipulation. SOAP is the most complex API protocol and is best suited for large-scale data mining operations.
Warp Up
Selenium is a portable software testing framework for web applications. Selenium provides a playback and record tool for authoring functional tests without the need to learn a test scripting language.
Selenium architecture is based on the client-server model. The client library is used to launch and control the browser. The server component interacts with the browser using the WebDriver wire protocol.
