Continuous Integration (CI) is a development practice that allows us to verify checked-in code using an automated build and to detect problems early. [**Travis**](https://travis-ci.org/) is a continuous integration tool that, once configured, takes care of these tasks and let us save a lot of time (that we can use to actually write code). Travis-ci.org is an online service that works with GitHub (it requires we use GitHub as the repository for our code), and once we have connected the two accounts and configured a very simple file in our projects, it’s automatically triggered when we push on our GitHub repository. [**Coveralls**](https://coveralls.io/)runs tests and checks the percentage of the source code that is covered by tests, producing a nice report that shows us the percentage for every single file/module and even the lines of code that have been tested. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://craftacademy.gitbook.io/coding-as-a-craft-2-0/week-1-programming-basics-rubyt/extras.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
