In this section and the following subsections, we are going to tackle some of the problems described in Alice's story. Because the code we inherited from the example is already implemented, we can't apply TDD here. Instead, we are going to set the basis and prepare the ground for future developments where applying TDD will become very useful.

Although there are always many things that can be improved, the pain points being addressed are code merging issues, lots of manual testing, manual releases, and the length of time taken to develop changes or new features.

For the first two, we are going to increase the test coverage of the application and implement CI. A Jenkins server is going to be configured to address the third issue, manual releases. And finally, the last issue, which is the long time to market (TTM), is going to be mitigated by implementing the rest of the solutions.
