The potential benefits of containerization are being discovered across the breadth and the length of software engineering. Previously, testing sophisticated software systems involved a number of expensive and hard-to-manage server modules and clusters. Considering the costs and complexities involved, most of the software testing is accomplished using mocking procedures and stubs. All of this is going to end for good with the maturity of the Docker technology. The openness and flexibility of Docker enable it to work seamlessly with other technologies to substantially reduce the testing time and complexity.
For a long time, the leading ways of testing software systems included mocking, dependency, injection, and so on. Usually, these mandate creating many sophisticated abstractions in the code. The current practice for developing and running test cases against an application is actually done on stubs rather...
