Run Tests in CI
Against a
Real Environment

mirrord for CI lets you test against your shared staging or pre-prod environment in Kubernetes, without deploying code to it or having to spin up test environments.

Enable cheap, fast, production-accurate testing.

How It Works in Just 3 Steps

1. Connect

CI runner securely connects to your existing Kubernetes cluster (e.g. your staging or pre-prod cluster).

2. Test

Your test suite runs with real services, dependencies, and traffic (isolated and safe, without the risk of interfering with other CI runners or developers working on the cluster )

3. Ship

Avoid production surprises by testing against real conditions. Move from "waiting for the build" to "shipping the feature".

“mirrord for CI gave us faster, better CI feedback at a lower cost. It lets us safely run tests against our staging environment, cutting our CI runtime by about 50%.”

Why Engineering Leaders are opting for

Currently, teams are forced to choose between two inefficient paths:

PATH 1

The Lie of Mocks

Relying on mocks that fail to reflect the complexity of real-world Kubernetes behavior.

PATH 2

The Cost of Replicas

Wasting 20+ minutes spinning up ephemeral clusters that spike your cloud bill and slow down your development velocity.

The Solution

mirrord for CI

It closes this gap by introducing a new category of testing:
real-environment CI.

It lets your CI runners test directly against real services, data, and configurations in your Kubernetes clusters.

What Real-Environment CI brings to Continuous Integration Pipelines

Traditional CI

  • Mocks, sandboxes or ephemeral Clusters

  • Spin-up delays: 20 mins spin-up/spin-down time

  • Synthetic context with low production fidelity

  • High infrastructure costs (duplicate clusters)

  • Bugs slip through production

Real-Environment CI

with mirrord for CI

  • Safely connect to real services, configs, and network behavior 

  • No setup, no deployment, and instant feedback.

  • Production-like context

  • Zero Duplication. Uses Existing Infra

  • Catch integration issues often and early

FAQ.

skeptics-welcome

How much does it cost?

mirrord for CI is part of the mirrord Enterprise plan.

Does this replace my existing CI provider?

No. mirrord for CI augments your existing CI (like GitHub Actions) by providing runners with secure, isolated access to your Kubernetes cluster.

Is it safe to run tests against a shared staging environment?

Yes. mirrord ensures that test traffic doesn’t interfere with other workloads.

How long does it take to set up?

With mirrord for CI, you’re able to keep your staging environment working, while also running your batch of end-to-end and other automated tests. The local app runs in the context of the targeted app that’s deployed in your staging cluster, so it gets access to traffic, files, and more, as if it’s running in the cluster. This means there’s no need to spin up a whole test environment for a CI run, then spin it down when it’s done. Read more here or meet with us for free to get a quote.

Do I need to buy mirrord to try mirrord for CI?

mirrord for CI is a feature of our Enterprise plan. However, you can experience the core mirroring technology via our open-source version, or schedule a demo to see the CI-specific isolation and automation features in action

How does it handle databases?

mirrord for CI can leverage mirrord’s Database Branching capability to spin up an isolated database for testing, while using all other resources on the shared cluster.

What about security?

We support RBAC and don’t require root access on the local runner.

How much time can it save me?

We’re aware of teams that spent 40 hours a month maintaining mocks that still missed a production bug. mirrord changed that in an afternoon.

How does it reduce my Cloud bill?

Ephemeral clusters often take a significant cut of  devops budget. mirrord regularly brings that down. Even millions of dollars down.

What is real-environment CI?

mirrord for CI brings a new category to DevOps and Platform teams: real-environment CI. Teams validate code against an already-running Kubernetes environment, eliminating spin-up time, while safely testing in real production-like context. This fundamentally raises the bar for how cloud-native software is tested and shipped.
