Overview of this book

Microservices are the latest "right" way of developing web applications. Microservices architecture has been gaining momentum over the past few years, but once you've started down the microservices path, you need to test and optimize the services. This book focuses on exploring various testing, monitoring, and optimization techniques for microservices. The book starts with the evolution of software architecture style, from monolithic to virtualized, to microservices architecture. Then you will explore methods to deploy microservices and various implementation patterns. With the help of a real-world example, you will understand how external APIs help product developers to focus on core competencies. After that, you will learn testing techniques, such as Unit Testing, Integration Testing, Functional Testing, and Load Testing. Next, you will explore performance testing tools, such as JMeter, and Gatling. Then, we deep dive into monitoring techniques and learn performance benchmarking of the various architectural components. For this, you will explore monitoring tools such as Appdynamics, Dynatrace, AWS CloudWatch, and Nagios. Finally, you will learn to identify, address, and report various performance issues related to microservices.

End-to-end testing

With end-to-end testing, an application is tested to check whether or not it has a complete flow from the beginning to the end. Through end-to-end testing, any system dependencies are weeded out and integrity between different components is maintained. Here, the intention is to verify that the system as a whole meets business goals, irrespective of the component architecture in use.

In a microservice-based application, end-to-end testing provides value by covering the gaps between the services.

End-to-end testing checks all the critical functionalities for any bugs or anomalies, such as communication within or outside of the system, the application's interface, the database, network, and other components. There are two different ways of performing end-to-end testing:

  • Horizontal end-to-end testing: This is the more common method for implementing end-to...
