| api testing postman interview questions: Test Driven Development Kent Beck, 2022-03-25 Quite simply, test-driven development is meant to eliminate fear in application development. While some fear is healthy (often viewed as a conscience that tells programmers to be careful!), the author believes that byproducts of fear include tentative, grumpy, and uncommunicative programmers who are unable to absorb constructive criticism. When programming teams buy into TDD, they immediately see positive results. They eliminate the fear involved in their jobs, and are better equipped to tackle the difficult challenges that face them. TDD eliminates tentative traits, it teaches programmers to communicate, and it encourages team members to seek out criticism However, even the author admits that grumpiness must be worked out individually! In short, the premise behind TDD is that code should be continually tested and refactored. Kent Beck teaches programmers by example, so they can painlessly and dramatically increase the quality of their work. |

| api testing postman interview questions: Java for Testers MR Alan J Richardson, 2015-08-06 This book is for people who want to learn Java. Particularly people on a team that want to learn Java, but who aren't going to be coding the main Java application i.e. Testers, Managers, Business Analysts, Front End Developers, Designers, etc. If you already know Java then this book may not be for you. This book is aimed at beginners. Designed to help the reader get started fast, the book is easy to follow, and has examples related to testing. You can find the companion web site for the book at http: //javafortesters.com The book covers 'just enough' to get people writing tests and abstraction layers. For example, the book cover the basics of Inheritance, but doesn't really cover Interfaces in detail. We explain the concept of Interfaces, because we need to know it to understand Collections, but not how to write them. Why? Because the book covers enough to get you started, and working. But not overload the reader. Once you are on your way, and have gained some experience. You should have the basic knowledge to understand the additional concepts. Why 'for testers'? Java Developers coding production applications in Java need to learn Java differently from other people on the team. Throughout the author's career, he has have written thousands of lines of Java code, but has rarely had to compile the code into an application. Yet, when we learn Java from most books, one of the first things we learn is 'javac' and the 'main' method and working from the command line. And this is confusing. Most of the code the author writes is wrapped up in a JUnit @Test method. The author has trained many people to write automation in Java, and everytime he has taught Java to testers or other people on the team, we start with a JUnit @Test method and run tests from the IDE. Testers, and other people on the team use java differently. This book provides a different order and approach to learning Java. You can find the source code for all examples and exercises used in the book over on github: https: //github.com/eviltester/javaForTestersCode |
| api testing postman interview questions: Integrative Framing Analysis Viorela Dan, 2017-09-13 Much of framing scholarship focuses either exclusively on the analysis of words or of visuals. This book aims to address this gap by proposing a six-step approach to the analysis of verbal frames, visual frames and the interplay between them—an integrative framing analysis. This approach is then demonstrated through a study investigating the way words and visuals are used to frame people living with HIV/AIDS in various communication contexts: the news, public service announcements and special interest publications. This application of integrative framing analysis reveals differences between verbal frames and visual frames in the same messages, underscoring the importance of looking at these frames together. |

Gain the essential skills needed to quickly design, build, and deploy quality web APIs that are robust, reliable, and resilient. Go from initial design through prototyping and implementation to deployment of mission-critical APIs for your organization. Test, secure, and deploy your API with confidence and avoid the release into production panic. Tackle just about any API challenge with more than a dozen open-source utilities and common programming patterns you can apply right away. Good API design means starting with the API-First principle - understanding who is using the API and what they want to do with it - and applying basic design skills to match customers' needs while solving business-critical problems. Use the Sketch-Design-Build method to create reliable and scalable web APIs quickly and easily without a lot of risk to the day-to-day business operations. Create clear sequence diagrams, accurate specifications, and machine-readable API descriptions all reviewed, tested, and ready to turn into fully-functional NodeJS code. Create reliable test collections with Postman and implement proper identity and access control security with AuthO-without added cost or risk to the company. Deploy all of this to Heroku using a continuous delivery approach that pushes secure, well-tested code to your public servers ready for use by both internal and external developers. From design to code to test to deployment, unlock hidden business value and release stable and scalable web APIs that meet customer needs and solve important business problems in a consistent and reliable manner. |

| api testing postman interview questions: Grokking the System Design Interview Design Gurus, 2021-12-18 This book (also available online at www.designgurus.org) by Design Gurus has helped 60k+ readers to crack their system design interview (SDI). System design questions have become a standard part of the software engineering interview process. These interviews determine your ability to work with complex systems and the position and salary you will be offered by the interviewing company. Unfortunately, SDI is difficult for most engineers, partly because they lack experience developing large-scale systems and partly because SDIs are unstructured in nature. Even engineers who've some experience building such systems aren't comfortable with these interviews, mainly due to the open-ended nature of design problems that don't have a standard answer. This book is a comprehensive guide to master SDIs. It was created by hiring managers who have worked for Google, Facebook, Microsoft, and Amazon. The book contains a carefully chosen set of questions that have been repeatedly asked at top companies. What's inside? This book is divided into two parts. The first part includes a step-by-step guide on how to answer a system design question in an interview, followed by famous system design case studies. The second part of the book includes a glossary of system design concepts. Table of Contents First Part: System Design Interviews: A step-by-step guide. Designing a URL Shortening service like TinyURL. Designing Pastebin. Designing Instagram. Designing Dropbox. Designing Facebook Messenger. Designing Twitter. Designing YouTube or Netflix. Designing Typeahead Suggestion. Designing an API Rate Limiter. Designing Twitter Search. Designing a Web Crawler. Designing Facebook's Newsfeed. Designing Yelp or Nearby Friends. Designing Uber backend. Designing Ticketmaster. Second Part: Key Characteristics of Distributed Systems. Load Balancing. Caching. Data Partitioning. Indexes. Proxies. Redundancy and Replication.

| api testing postman interview questions: Clean Agile Robert C. Martin, 2019-09-12 Agile Values and Principles for a New Generation “In the journey to all things Agile, Uncle Bob has been there, done that, and has the both the t-shirt and the scars to show for it. This delightful book is part history, part personal stories, and all wisdom. If you want to understand what Agile is and how it came to be, this is the book for you.” –Grady Booch “Bob’s frustration colors every sentence of Clean Agile, but it’s a justified frustration. What is in the world of Agile development is nothing compared to what could be. This book is Bob’s perspective on what to focus on to get to that ‘what could be.’ And he’s been there, so it’s worth listening.” –Kent Beck “It’s good to read Uncle Bob’s take on Agile. Whether just beginning, or a seasoned Agilista, you would do well to read this book. I agree with almost all of it. It’s just some of the parts make me realize my own shortcomings, dammit. It made me double-check our code coverage (85.09%).” –Jon Kern Nearly twenty years after the Agile Manifesto was first presented, the legendary Robert C. Martin (“Uncle Bob”) reintroduces Agile values and principles for a new generation–programmers and nonprogrammers alike. Martin, author of Clean Code and other highly influential software development guides, was there at Agile’s founding. Now, in Clean Agile: Back to Basics, he strips away misunderstandings and distractions that over the years have made it harder to use Agile than was originally intended. Martin describes what Agile is in no uncertain terms: a small discipline that helps small teams manage small projects . . . with huge implications because every big project is comprised of many small projects. Drawing on his fifty years’ experience with projects of every conceivable type, he shows how Agile can help you bring true professionalism to software development. Get back to the basics–what Agile is, was, and should always be Understand the origins, and proper practice, of SCRUM Master essential business-facing Agile practices, from small releases and acceptance tests to whole-team communication Explore Agile team members’ relationships with each other, and with their product Rediscover indispensable Agile technical practices: TDD, refactoring, simple design, and pair programming Understand the central roles values and craftsmanship play in your Agile team’s success If you want Agile’s true benefits, there are no shortcuts: You need to do Agile right. Clean Agile: Back to Basics will show you how, whether you’re a developer, tester, manager, project manager, or customer.

| api testing postman interview questions: Lessons Learned in Software Testing Cem Kaner, James Bach, Bret Pettichord, 2011-08-02 Softwaretests stellen eine kritische Phase in der Softwareentwicklung dar. Jetzt zeigt sich, ob das Programm die entsprechenden Anforderungen erfüllt und sich auch keine Programmierungsfehler eingeschlichen haben. Doch wie bei allen Phasen im Software-Entwicklungsprozess gibt es auch hier eine Reihe möglicher Fallstricke, die die Entdeckung von Programmfehlern vereiteln können. Deshalb brauchen Softwaretester ein Handbuch, das alle Tipps, Tricks und die häufigsten Fehlerquellen genau auflistet und erläutert, damit mögliche Testfehler von vornherein vermieden werden können. Ein solches Handbuch ersetzt gut und gerne jahr(zehnt)elange Erfahrung und erspart dem Tester frustrierende und langwierige Trial-und-Error-Prozeduren. Chem Kaner und James Bach sind zwei der international führenden Experten auf dem Gebiet des Software Testing. Sie schöpfen hier aus ihrer insgesamt 30-jährigen Erfahrung. Die einzelnen Lektionen sind nach Themenbereichen gegliedert, wie z.B. Testdesign, Test Management, Teststrategien und Fehleranalyse. Jede Lektion enthält eine Behauptung und eine Erklärung sowie ein Beispiel des entsprechenden Testproblems. Lessons Learned in Software Testing ist ein unverzichtbarer Begleiter für jeden Software Tester. |
| api testing postman interview questions: Smart and Gets Things Done Avram Joel Spolsky, 2007-10-17 A good programmer can outproduce five, ten, and sometimes more run-of-the-mill programmers. The secret to success for any software company then is to hire the good programmers. But how to do that? In Joel on Hiring, Joel Spolsky draws from his experience both at Microsoft and running his own successful software company based in New York City. He writes humorously, but seriously about his methods for sorting resumes, for finding great candidates, and for interviewing, in person and by phone. Joel’s methods are not complex, but they do get to the heart of the matter: how to recognize a great developer when you see one. |
| api testing postman interview questions: Practical Web Test Automation Zhimin Zhan, 2014-10-10 While few people deny the benefits of test automation, comprehensive automated testing via UI (browser for web applications) is rarely implemented in software projects. Common reasons for projects' failed attempts on test automation are: Difficult to learn - test scripts are complex and testing tools are not easy to use Hard to maintain - UI tests are vulnerable to application changes Long feedback loop - automated tests take too long to run To succeed in automated testing via UI, software projects need to overcome all these 3 chellenges. This book presents a practical approach to implementing test automation for web applications. Topics include: Developing easy to read and maintain Watir/Selenium tests using next-generation functional testing tool Page object model Functional Testing Refactorings Cross-browser testing against IE, Firefox and Chrome Setting up continuous testing server to manage execution of a large number of automated UI tests Requirement traceability matrix Strategies on team collaboration and test automation adoption in projects and organizations |

| api testing postman interview questions: Automating and Testing a Rest API Alan J. Richardson, 2017-07-04 Have you ever wished that you had a worked example of how to test a REST API? Not just automate the API, but how to interact with it, using command line and GUI tools, to support your manual interactive testing. Then take your testing forward into automating the API? That's what this book provides. A step by step case study covering: - How to read the REST API documentation. - How to tell if the application is using the API. - How to interact with the API from the command line with cURL. - Automating with BASH and Windows Command Line. - Sending API requests through an HTTP Proxy so you can see in detail the requests and responses. - How to use HTTP Proxies to create data in the application through Fuzzing. - Postman REST API GUI tool. - Automate 'under the GUI' parts of the application that don't have an API. - Automate the API with Java using REST Assured. - Build abstraction code to make your automated efforts readable and maintainable. - JSON and XML parsing with Serialization and Deserialization. The book is fully supported by executable code which you can find on GitHub, and the support page for the book has sample videos showing some of the early steps in the case study in detail. By working through this case study you will be able to interact with an API from the command line, GUI tools, HTTP messages in Proxies and with Java code. Over the last few years, the Author has used the Open Source Tracks application as an example testing target to teach: Technical Web Testing, Automating GUIs and REST API Testing. This book collates the preparatory work and teaching from the REST API workshops. The code from the workshops is included: for creating users, generating random data, testing basic API calls with PUT, GET, POST and DELETE. Also the early steps of exploring and investigating the API interactively to support manual technical testing are explained in depth. |
