Integration Testing a Cloud Native Application with JavaScript

August 31, 2020 0

This talk will take you through the challenge of testing a cloud-native application that uses MQTT (a pub/sub protocol), webhooks and REST to interact with IoT devices on top of AWS. It uses services which cannot be run on a developers machine for testing, so it was needed to develop a test setup which enables us to continuously test against real services.

Integration & End-to-End Testing with TestContainers and JUnit 5

December 9, 2019 1

The TestContainers library facilitates simple start up of a service dependencies, i.e. Postgres, Redis in throwaway Docker containers. This open source library works over Docker API and has a list of features which significantly improve a software developer experience.

Safe Software Testing in Production

September 23, 2019 1

Performing software testing in production is not a taboo anymore in our era of cloud computing and DevOps. This article discusses different types and approaches to do software testing in production and associated contexts, during which one or another kind of functional testing is useful. Also, we will describe in detail about the effective organization of the safe testing of various services in production.

Automatic Testing of a Heavily Integrated Software

August 26, 2019 0

Running more than 5000 automated system tests on a deployed application with outgoing connections to about 25 other systems, each with their own dependencies, where test data is complex and needs to be in-sync, is a great challenge. Doing it every night, year after year, with the requirement to fail only on the event of actual errors in the application under test, is a nightmare.

Software Testing in a Non-Deterministic World

January 23, 2019 1

Most of the time, software testing is based on comparing the actual behavior of a code or a system with its expected behavior. In his article “The Challenges of Testing in a Non-Deterministic World”, Donald Firesmith explains however that not all software and systems are deterministic, for instance an autonomous adaptive vehicle that uses machine learning software, and that software testing needs to adapt to this context.

Staying Sane While Testing the Hard Stuff

December 17, 2018 2

Even the best software test suites can’t entirely prevent nasty surprises: race conditions, unexpected interactions, faults in distributed protocols and so on, still slip past them into production. Yet writing even more tests of the same kind quickly runs into diminishing returns. This talk presents new software testing automated techniques that can dramatically improve your software testing, letting you focus on what your code should do, rather than which cases should be tested.

Painless Integration Testing with TestContainers

May 2, 2018 0

Testcontainers is an open source Java 8 library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.
