Web services have been at the core of modern application architectures for many years. Regardless of what language or platform a developer is using, grasping how web services work and how to implement them are critical skills. In this course, instructor Kesha Williams steps through how to work with several popular technologies to build web services. Kesha begins by laying the groundwork for the course, explaining what web services are and the benefits they provide. She then offers a comparison of several popular web service technologies—REST, SOAP, and GraphQL—describing each technology's messaging formats in detail, along with examples of coding in several languages using a variety of server- and client-based implementations. Plus, get coding excerpts in Java, Python, and Swift.

As software companies continue to shift towards cloud computing, mobile apps, and microservice architectures, the ability to quickly and effectively test APIs has become a critical skill for software testers. In this course, instructor Dave Westerveld covers the basics of API testing, sharing how to work with several robust tools for testing APIs at scale in an organization. After providing a primer on web services and important API terminology, Dave shows how to use Postman for some basic API exploration. He then goes over some basic approaches and methodologies used in testing GET, POST, PUT, and DELETE requests; shows how to approach performance testing using SoapUI, a popular automated API testing tool; and more.

Trying to choose a tool to perform software testing? The market is a minefield, full of so many choices that it becomes difficult to zero in on the best tool for your unique test environment. This course surveys the most popular software testing tools available, including paid and open-source solutions such as Selenium, Postman, JMeter, and Kali Linux. Instructor Michael Smith—an experienced tester and software architect—breaks down the tools according to their suitability for each discipline, including API testing, security testing, load testing, and more. He also covers tools for lifecycle management and test planning, and dives into areas beyond the traditional software testing role, including unit and infrastructure testing. This review helps you narrow down your choices and understand the pros and cons of each platform, so you can make the right additions to your testing toolkit.

With industry trends like cloud computing and the Internet of Things, there is a growing need for testers that know and understand API testing tools. One powerful and mature tool used by companies around the world is SoapUI. This course is designed to help you get started with SoapUI and covers the basics of how to use it. Instructor Dave Westerveld explains how to set up your first project, create new tests, perform load and security testing, and make your tests more automated and efficient with scripting. Plus, learn how to integrate SoapUI with Docker-based build pipelines. The training is filled with examples featuring real-world, public APIs so you can see how SoapUI functions in real testing scenarios.
