I've been a developer for about 3 years now, but my team never really focused on unit testing or established a proper CI/CD workflow. Most of my experience is with small personal frontend projects and not much with databases or backend infra. As I start looking for new job opportunities, I realize these skills are vital, and I'm feeling a bit lost.
I'd love to hear from anyone who can relate to this! How did you get started learning about testing, deployment, and setting up CI/CD pipelines from scratch? Are there specific resources or practices that helped you along the way? Any tips or advice would really mean a lot—I'm eager to improve but feeling quite overwhelmed!

Make sure to be open about what you haven't learned yet, but show that you're actively looking to improve! Even having basic examples ready to discuss can really show your initiative.
Automated testing can be tricky for anyone, especially if you haven't been set up for it from the beginning. It takes a solid structure in your code to be able to integrate with testing suites. Just remember, a CI/CD pipeline can be as simple as a bash script that builds and deploys your code without any fancy tools. I learned a lot by setting up GitLab and automating builds that kicked off every night to a dev server!
Totally get where you're coming from! A lot of developers overlook testing and CI/CD in the beginning, but it really becomes essential as your projects grow. I suggest starting small—try writing unit tests for your personal projects with Jest (for frontend) or xUnit/NUnit (for backend). For CI/CD, GitHub Actions is super user-friendly and free for smaller projects. There are loads of tutorials out there that show you how to deploy a full-stack app with tests and pipelines. Once you see it working, it'll all click for you! You're not behind, just on the cusp of moving to the next level. Good luck!
Testing is basically just running your code and checking whether it works. Sure, frameworks make it seem complicated, but it’s about getting comfortable tackling those setups. I'd recommend trying to create your own simple testing framework to understand the basics. Also, Continuous Integration (CI) just means automating your tests—it's not as hard as it seems. Continuous Deployment (CD) involves writing scripts to deploy your app, which can be hands-on with something like a Docker container. Getting into the nitty-gritty is a great way to learn the essential steps for bootstrapping an app. Just enjoy the learning process!
I totally resonate with that! I learned using containers on Google Cloud Run, which has a nice free tier. I keep things organized with separate Dockerfiles for my environments and have my logging down—I feel pretty solid in DevOps now!
I really wouldn’t advise reinventing the wheel with a new testing framework, though. Use existing frameworks—they save you a lot of hassle!
