RESTful API / AWS Engineers

REST API, which stands for Representational State Transfer Application Programming Interface, is an architectural style for designing networked applications. It is commonly used in web service development to allow communication between systems over the internet. REST is an acronym coined by Roy Fielding in his doctoral dissertation, and it emphasizes a stateless client-server communication model.

Key characteristics of a REST API include:

  1. Statelessness: Each request from a client to a server contains all the information needed to understand and fulfill that request. The server does not store any information about the client's state between requests.

  2. Resource-Based: Resources, such as data or services, are identified by unique URLs (uniform resource locators). Clients interact with these resources using standard HTTP methods, such as GET, POST, PUT, and DELETE.

  3. Representation: Resources are represented in a format, such as JSON or XML, which is agreed upon by the client and server. This representation can be used to manipulate the resource's state.

  4. Uniform Interface: REST APIs follow a uniform interface that simplifies communication. This includes using standard HTTP methods, resource identification through URLs, and a consistent representation format.

  5. Stateless Communication: Each request from a client to a server is independent and contains all the information necessary for the server to fulfill that request. The server does not store any information about the client's state between requests.

  6. Client-Server Architecture: The client and server are separate entities that communicate over a network. The client is responsible for the user interface and user experience, while the server handles the application's business logic and data storage.

  7. Cacheability: Responses from the server can be explicitly marked as cacheable or non-cacheable. This allows clients to cache responses and improve performance.

Selenium Developers

A Selenium developer is a professional with expertise in using the Selenium framework for automated testing of web applications.

These scripts simulate user interactions with web applications, allowing for the testing of various functionalities. Web Element Identification: Selenium developers are skilled in locating and interacting with web elements on a page. They use various locators such as IDs, classes, XPath, and CSS selectors, to accurately identify and manipulate elements during testing. Test Frameworks: Selenium developers often work with testing frameworks like TestNG, JUnit, or NUnit to organize and manage test cases. These frameworks provide a structured approach to test automation, enabling efficient test development and execution. Integration with Continuous Integration (CI) Systems: Selenium developers integrate automated tests into CI systems such as Jenkins or Travis CI. This ensures that tests are automatically executed whenever there is a code change, providing rapid feedback to development teams. Cross-Browser Testing: Selenium developers conduct cross-browser testing to ensure that web applications perform consistently across different web browsers like Chrome, Firefox, Safari, and Internet Explorer. Parallel Test Execution: Selenium developers implement parallel test execution to optimize testing time. This involves running multiple tests simultaneously, improving efficiency and reducing the overall test execution duration. Page Object Model (POM): Selenium developers often follow the Page Object Model design pattern. POM helps in creating maintainable and scalable test scripts by representing each web page as a separate class, encapsulating the page's elements and functionality. Dynamic Waiting Strategies: Selenium developers implement dynamic waiting strategies to handle synchronization issues during test execution. This ensures that tests wait for the appropriate elements to load before proceeding, preventing false test failures. Reporting and Logging: Selenium developers use reporting tools like ExtentReports or Allure to generate detailed test reports. These reports provide insights into test execution results, making it easier to identify and address issues. Continuous Learning: As technology evolves, Selenium developers stay updated with the latest features and best practices within the Selenium ecosystem.
