Aaron Bedra focuses on describing a system as a series of models that can be used to systematically and automatically generate input data and ensure that a code is behaving as expected.
Dave Farley discusses using acceptance testing to work quickly and effectively, building functional coverage for complex enterprise-scale systems, and managing and maintaining those tests.
Sam Adams talks about testing at LMAX Exchange, extending functional tests into live monitoring of production through isolation, and moving fast through incremental delivery, quality and automation.
Mathieu Bastian explores the mechanics of unit, integration, data and performance testing for large, complex data workflows, along with the tools for Hadoop, Pig and Spark.
Pawel Sawicz suggests putting tests to the test by mutating the code to see if the codebase is properly covered by tests and how errors are propagated.
Tammer Saleh talks about the mistakes made building microservices, when microservices are appropriate, where to draw the lines between services, performance issues, testing, debugging, failure, etc.
Rachel Reese talks about Jet.com's chaos testing methods and code in depth, but also lays out a path to implementation that everyone can use.
Russ Miles shows how we can build production-level confidence in our polyglot microservices by applying the test-driven approach to synchronous (REST) and asynchronous (Messaging) services.
Ken Kousen talks about Geb, which makes it easy to automate browser-based applications. Geb is based on the Spock testing framework, providing a straightforward syntax and easy execution model.
Iván López discusses the basics of Spock and how easily one can test a Java application. Spock is a Groovy-based testing and specification framework for Java and Groovy applications.
Brannen and Fränkel cover the latest testing features in Core Spring, Spring Boot, and Spring Security, and tips on integration testing with TestNG, DB transactions, SQL script execution, etc.
Katrina Clokie discusses how BNZ does web (SOAP, REST) services testing, the tools and practices employed and some of the resources and exercises their testers use to learn how to test.
