Conclusion

Getting a Gatsby site ready to go live in production isn’t just a matter of putting the finishing touches on implementation. During the development process, it’s often the case that small bugs or larger issues creep into code that can stymie even the best-planned development cycle. For this reason, Gatsby provides a robust set of tools for testing Gatsby sites during implementation and debugging issues as they arise.

Fortunately, many of the practices we’ve outlined in this section are foundational to JavaScript or Node.js in addition to Gatsby itself, but that doesn’t mean that developers building Gatsby sites should give testing and debugging short shrift on the journey to a live Gatsby site. The tools and techniques covered in this section will serve you particularly well as we move on to our next topic, deploying Gatsby sites, where it’s a bit less permissible for things to go wrong—especially when building for customers.
