Traditional Definition of Web Service: ========================================= - WebServices are XML-Centered data exchange systems that uses the INTERNET for communication 2. Key Features of Web Service: =============================== - Web Service is an APPLICATION that can be written in various languages and are still able to communicate by exchanging the data with one another via a Web service between clients and servers. - A client summons a web service by sending a request via XML, and the service then responses with an XML response. 3. Important Points about Web Service: ====================================== - Available over the Internet or Intranet networks. - Independent of a single operating system or a programming language - Discoverable through a simple location method. 4. Types of Web Services: ======================== - XML-RPC (XML - Remote Procedure Call) - UDDI (Universal Description, Discovery and Integration) - SOAP - REST 5. RESTful Web Services: ======================== - REST -- REpresentational State Transfer - REST is an architectural style, meaning each unique URL represents an individual object of some sort. - A REST web service uses HTTP and supports several HTTP methods like GET, POST PUT and DELETE 6. Advantages of RESTful Web services or Pros of RESTful WebService: ==================================================================== - Lightweight - Human Readable - Easier to build 7. Cons of RESTful Web Services: ================================ - Point-to-Point communication - Less standards when compare to SOAP 8. SOAP Web Services: ===================== - SOAP -- Simple Object Access Protocol - This web service protocol exchanges structures data using XML and generally HTTP and SMTP for transmission. - SOAP uses WSDL (Web Services Description Language) documents to distribute a Web Service description model. - WSDL describes how the SOAP requests and responses must appear. - SOAP Web Servies have standards for security and addressing 9. Pros of SOAP Web Services: ============================= - Easier to Consume - More Standards 10. Cons of SOAP Web Services: ============================== - Difficult to setup - More complicated coding - Harder to develop Protractor with Javascript - https://bit.ly/2jZ5XkX Selenium Java Tutorial - https://bit.ly/2keM2Pb Jasmine Tutorial - https://bit.ly/2lv0m6l Java - https://bit.ly/2lylSHq TestNG Tutorial - https://bit.ly/2lTpB2d PdfUtil - https://bit.ly/2keBDTA Shutterbug - https://bit.ly/2lX6xQV Selenium Realtime Examples - https://bit.ly/2k0FqDQ Java Interview Questions - https://bit.ly/2kopsmY Katalon Studio - https://bit.ly/2lWhyln Database Testing - https://bit.ly/2ko4jcJ Fillo Excel API - https://bit.ly/2jRyWqC Ashot - https://bit.ly/2kqXk2y Extent Reports Version 3 Java - https://bit.ly/2k0FweG Robot class - https://bit.ly/2lshPfJ Sikuli - https://bit.ly/2lTq2cR Excel Read Write using Java - https://bit.ly/2lyXRj8 AutoIt - https://bit.ly/2lyIYgM Extent Reports Version 2 C# - https://bit.ly/2kqIY2d Extent Reports Version 2 Java - https://bit.ly/2k0XkGA Facebook : https://www.facebook.com/automationtesting2016/ LinkedIn : https://www.linkedin.com/feed/?trk=hb_signin Google+ : https://plus.google.com/105286300926085335367 Twitter : https://twitter.com/krishnasakinala Website : http://automationtesting.in/
