Try to keep units small, use appropriate tools, and pair-up programmers and tester; these are suggestions for writing good unit tests. Unit testing is a mixture of programming and testing; programmers can work together with testers to learn from each other and broaden their knowledge horizons.
The 2017 State of Testing survey aims to provide insights into how the testing profession develops. The survey is open throughout January 2017.

To drive operational maturity you need a microservices architecture, continuous delivery process, DevOps culture and platform automation. Together these four help you to transform your whole organization for achieving cloud-native operability to continuously deliver additional value to your customers.
Continuous delivery should be treated as an agile project as it is about automating your deployment. You have to speed up in small steps and gain trust by doing small deliveries and solve problems fast. The story about how Klaverblad insurance has implemented Agile, DevOps, continuous delivery, and microservices.
At the sixth ‘Agile on the Beach’ conference, held in Cornwall, UK, several leading practitioners of agile software delivery presented the state-of-the-art and emerging trends within this domain. Key takeaways included the value of the scientific method to drive change; the use of Continuous Delivery (CD) for improving safety and speed; and the power of cognitive bias during the user testing.
Moving towards microservices means moving towards distributed systems where you have to deal with latency, authorization and authentication, and messages that do not arrive, argues Sander Hoogendoorn. With microservices you can break down large systems into smaller components to regain control over the architecture.
Continuous deployment results in a higher sense of responsibility and better quality of deployments, argues Paul de Raaij, technical pathfinder at Coolblue. Coding standards prevent your code base from becoming a mess, automated inspections are great for tedious and boring checks, and manual checks are great for checking if the logic or use of code actually makes sense.
Test Butler is an open-source testing tool for Android that aims to allow developers to reliably run UI tests, writes LinkedIn engineer Drew Hannay and creator of Test Butler, by allowing developers to programmatically control a number of testing environment settings.
WireMock v2, an API mocking and service virtualisation tool, has been released.
