Top 5 CI Anti-Patterns That Are Slowing You Down

Top 5 CI Anti-Patterns That Are Slowing You Down
CI is your delivery vessel. If it’s overloaded, off-course, or leaking—nobody’s getting clean code to production.

Your CI pipeline is supposed to help you move faster and ship with confidence.

But for many teams, CI has become a bottleneck instead of a launchpad—bloated with scripts, flaky tests, or noisy alerts. Instead of speeding you up, it saps engineering time and trust.

Let’s break the cycle.

In this post, I’ll cover the Top 5 CI anti-patterns I’ve seen over the years—across scrappy startups and regulated enterprises alike—and what to do instead.


1. “Test Everything on Every Commit” Syndrome

The Anti-Pattern:
Every time a dev pushes code, your pipeline runs every test—unit, integration, end-to-end, smoke, regression—across every environment.

It sounds safe, but it’s a performance and signal disaster.

  • Your pipeline becomes slow and expensive
  • Devs ignore results because they’re buried in noise
  • You're running tests that aren't even impacted by the change

The Fix:
Use test impact analysis, tag filtering, or path-based triggering.

  • Only run E2E tests when relevant code paths change
  • Run smoke tests first, then conditionally expand
  • Use monorepo-aware CI jobs that target affected areas

👉 Example (GitHub Actions):

.yml if: contains(github.event.head_commit.message, '[e2e]')


2. Flaky Test Roulette

The Anti-Pattern:
Flaky tests aren’t managed—they’re ignored, commented out, or just rerun endlessly in hopes they’ll pass. “Green is green,” right?

Wrong.

  • Flaky tests erode trust in the pipeline
  • Devs start ignoring all failures, not just the flakes
  • Root causes pile up and tech debt grows quietly

The Fix:
Build a flake triage system, not a culture of silence.

  • Auto-tag flaky tests with retry metadata
  • Log and track flake frequency over time
  • Make fixing flakes a sprint-level priority
  • Don’t confuse “rerun and pass” with “fixed”

👉 Example: Playwright's built-in retries config + trace recording is your friend.


3. No Signal in the Noise

The Anti-Pattern:
Your CI notifies everyone… about everything.

  • Every job posts to Slack
  • Every test result floods the dashboard
  • Build failed? Good luck parsing logs

Result? Alert fatigue.
CI becomes background noise—until something breaks in prod.

The Fix:
CI should surface just the right amount of signal.

  • Only notify on test failures or regressions
  • Use Slack summaries, not firehoses
  • Include direct links to traces, logs, or dashboards
  • Red = actionable; green = silence

👉 Bonus Tip: Set alerts to go to owners of broken components—not the whole team.


4. Pipeline Logic Hidden in the UI

The Anti-Pattern:
The CI pipeline was built in a rush using drag-and-drop GUI tools. No one knows exactly how it works anymore—and any change risks breaking prod.

  • No version control
  • No code review
  • No reproducibility between dev and CI

The Fix:
Your CI config should live in your repo, like everything else.

  • Use YAML (GitHub Actions, CircleCI, GitLab CI)
  • Split into modular, reusable jobs and workflows
  • Peer review all pipeline changes
  • Track history like you would code

👉 Treat CI config as infrastructure-as-code, not click-ops.


5. No Feedback on CI Health

The Anti-Pattern:
You’ve built a big, beautiful pipeline—but you’re flying blind.

  • How often are builds failing?
  • What’s your average build time?
  • Which tests flake the most?
  • How long does it take from commit → deploy?

You can’t improve what you can’t see.

The Fix:
Add CI metrics and observability.

  • Track failure rates, build duration, flake %
  • Use dashboards (Grafana, DataDog, GitHub Insights)
  • Set goals for test suite speed and reliability
  • Alert when thresholds are crossed

👉 Start simple: a weekly Slack report of CI pass/fail %, top slow tests, and mean time to green.


What Great CI Looks Like

Let’s flip the script. A healthy CI pipeline should be:

TraitWhat It Means
🧠 SmartRuns what’s needed, when it’s needed
🧹 CleanClear logs, no hidden scripts
💨 FastResults in <20 minutes, or it’s a smell
🧪 ReliableFailures are real, not flaky
📣 HelpfulNotifies with just enough context
📊 MeasuredYou know your time-to-green and flake rate

I’ve helped teams:

  • Refactor monolithic pipelines into modular workflows
  • Slash build times by 60%
  • Kill test flake by implementing smart retries + observability
  • Align CI to actual risk instead of just running everything
  • Turn CI from a black box into a strategic asset

Your CI should build trust—not tech debt.
