QA Automation

At CodiLime, we deliver end-to-end QA Automation solutions designed specifically for complex Modern Data Center topologies and software-defined networking platforms. We pair networking depth in routing, switching, and virtualization with real software engineering. Your teams catch problems earlier and ship faster. We test on physical appliances, virtual environments, and containerized testbeds, so multi-vendor architectures get validated continuously.

How a project runs

  1. Understand test architecture and requirements

    We analyze target network topologies, protocols, security, DUT interfaces, and existing testing bottlenecks. The result is the test automation strategy for modern data center environments.

  2. Provision on-demand test environments

    We automate provisioning and configuration of network testbeds with Infrastructure-as-Code: Terraform, Ansible, Kubernetes and Docker, including custom tools and integration solutions. Testbeds can be physical, virtual, SASE or containerized. They run in parallel, isolated from each other, and plug into CI/CD pipelines.

  3. Build modular test suites

    Our software engineers write maintainable, scalable automation frameworks using Python, Go, Pytest, and pyATS. The suites cover control plane, data plane, security policies, and APIs.

  4. Validate the system end to end

    We execute performance, scale, SASE/SD-WAN security, and infrastructure validation. That includes high-throughput traffic generation, protocol convergence (e.g., BGP/VXLAN), and security policy verification, with continuous end-to-end regression across complex physical and virtual network architectures.

  5. Integrate smart CI/CD and analytics

    We implement smart test selection, failure fingerprinting, and automated XFail tagging, and test run telemetry goes into Prometheus, Grafana, and Splunk for deep operational visibility.

  6. Deploy agentic AI for autonomous validation and RCA

    We deploy AI agents and Model Context Protocol (MCP) servers. They analyze live system state, dynamic failure context, and code changes to execute autonomous triaging and root-cause analysis.

Proof of capability

Why CodiLime

  • Engineers who code

    Our QA engineers are software engineers first. They build complete, scalable automation platforms, custom tooling, and orchestration environments that hold up against real infrastructure complexity.

  • Rare combination of networking depth and software engineering

    Networking is in our DNA. Deep domain knowledge in protocols like BGP, OSPF and VXLAN, combined with strong software engineering and DevOps practices, lets us design frameworks that understand the systems they’re testing. Physical, virtual and cloud-based components treated as one dynamically provisioned Modern Data Center environment, and other network platforms and appliances.

  • Flexible enough to build our own tools when needed

    When standard solutions don’t fit, whether due to cost, scale or specific client requirements. In those cases we build custom deployment tools and bespoke automation frameworks tailored to the environment, instead of forcing a one-size-fits-all approach. We’re equally comfortable with commercial tools and solutions and traffic generators like Ixia and Spirent, integrating them into automated test pipelines where they’re the right fit.

  • Catching what manual testing can’t see at scale

    Automation surfaces the invisible cracks in large, scaled environments: small regressions, QoS degradations, intermittent connectivity issues. They build up over time and are easy to miss with manual testing alone.

  • Forward-looking on AI and Digital Twin for Modern Data Center

    We work with Digital and Virtual Twin concepts to bring Modern Data Center test environments closer to production reality, and we invest in R&D such as AI-based root cause analysis focused on practical value.

FAQ

Good to know

  • How does CodiLime validate complex, multi-vendor Modern Data Center topologies without relying on expensive physical labs?

    CodiLime combines containerized testbed orchestration (using Docker and Kubernetes) with dynamic network emulation and physical hardware integration. This approach allows us to execute parallel test topologies on shared compute resources on demand, reducing physical lab overhead by up to 60% while expanding daily test execution capacity tenfold.

  • Can your QA automation frameworks integrate with our existing CI/CD pipelines and commercial traffic generators?

    Yes. CodiLime teams build modular test suites using Pytest, Robot Framework, Python, and Go that run in standard CI/CD engines such as Jenkins and GitLab CI. We integrate with commercial traffic generators such as Ixia and Spirent, and build custom open-source high-throughput engines such as TRex 200 Gbps.

  • How do you address high test maintenance overhead and false positives in large regression suites?

    CodiLime implements modular framework architectures, smart test selection based on code change impact, and automated failure classification (such as XFail tagging algorithms). By automatically identifying known non-blocking issues and deterministic failure patterns, we accelerate root-cause analysis from days to hours and prevent transient failures from delaying delivery pipelines.

  • What sets CodiLime’s QA automation engineers apart from traditional software testing vendors?

    Our QA engineers are software developers and networking domain specialists first. CodiLime brings deep, hands-on expertise in core protocols (BGP, OSPF, VXLAN, MPLS) and cloud-native architectures, enabling us to build scalable automation platforms, custom traffic tools, and dynamic environment orchestrators.

  • How can AI and agentic workflows enhance Data Center infrastructure validation?

    CodiLime utilizes Agentic AI models and MCP (Model Context Protocol) servers to analyze infrastructure telemetry, assess code impact, dynamically expand test coverage during anomalies, and perform automated root-cause analysis.

  • What is the typical timeline and engagement model for modernizing our QA automation platform?

    We usually start with a 2- to 3-week technical audit of your existing infrastructure, test scripts, and pipeline bottlenecks. We then build a targeted PoC or MVP such as an automated lab provisioning pipeline before scaling up full test suite development and transitioning knowledge to your team.

  • How do you handle performance and scale testing under extreme load conditions?

    CodiLime constructs both single-variable and multi-variable scale tests frameworks following RFC 2544 standards. By leveraging high-throughput engines like TRex alongside custom control-plane traffic generators, we stress-test data plane throughput, latency, and dynamic routing protocol convergence under load to catch subtle scaling bottlenecks before code hits production environments.

  • How do you validate overlay/underlay network protocols (e.g., BGP EVPN, VXLAN) and fabric configuration drift in Modern Data Centers?

    We build automated end-to-end regression suites that combine synthetic control plane traffic injection with automated state verification via telemetry and APIs. By comparing running states against desired Infrastructure-as-Code (Terraform/Ansible) definitions, our frameworks automatically detect configuration drift, protocol convergence delays, and asymmetric routing issues across leaf-spine and other topologies.

  • Can CodiLime help automate testing for microsegmentation and zero-trust security policies across containerized and virtual workloads?

    Yes. We automate functional and security validation for east-west traffic isolation, security policy enforcements, and firewall controller APIs. Using automated test engines, we simulate distributed workload traffic to verify that dynamic policy updates do not introduce security gaps, unintended drop rules, or performance bottlenecks.

  • How do you handle rapid API changes and SDK updates in complex Data Center SDN orchestrators?

    To eliminate manual maintenance of controller API interactions, CodiLime builds custom SDK generators that automatically create and update client libraries directly from controller API specifications. This auto-generation approach ensures seamless compatibility with new fabric orchestrator releases and drastically cuts ongoing framework maintenance costs.

  • How do you validate zero-downtime upgrades and live migrations of Data Center fabric switches and software components?

    CodiLime designs automated hitless upgrade validation workflows that monitor packet loss, session persistence, and convergence speed during simulated switch reboots and software upgrades. By combining high-precision traffic generation with real-time observability tools (Prometheus, Grafana, Splunk), we measure exact disruption metrics down to the millisecond to confirm whether failover stays under a second before production deployment.
