Testing With Container-Based Applications

Printer-friendly version

Chris Riley from Sauce Labs put a great explainer together on the optimal role for containerization of certain elements of the testing cycle. A key takeaway here is that, while containers are not directly impacting the GUI layer of functional tests, they provide an excellent way to promote “the entire depends farm” for a given functional component, so that as testing moves from one environment to the next, consistency of such items as libraries is well maintained. This means that a QA Tester can be confident that code will run the same in Prod as it does on his or her desktop. Which helps provide the grounding for a shift left strategy.
