By mid December, ThoughtWorks released an interesting ebook about practices and trend in Software Testing. It includes a variety of topics such as: Agile Testing, Defect prevention, Mocking, Test Automation techniques, BDD, Continuous Delivery, Protractor, Performance Testing, etc.
It also includes my article about “Performance Testing with Gatling”, which was previously published here by mid 2014.
I highly recommend reading the ebook. Unfortunately, it was only released in pt-BR (Brazilian Portuguese) language. However, you could easily use any translation tool to read it.
You can download the full ebook version here.
