How do small teams catch bugs in CI/CD?

Hi everyone 👋

I’m curious about the experience of small teams and startups when it comes to CI/CD.

Do your builds/tests often fail for unclear reasons?

How do you usually debug broken pipelines or weird logs?

Do you use custom scripts, GitHub Actions, GitLab CI, or something else?

I feel like small teams don’t always have a dedicated DevOps person, so I’m wondering:
👉 What’s the most painful part of dealing with CI/CD bugs for you?

Any examples, tools, or workflows you can share would be super helpful 🙏
