PROFILE
Christian Tschacher
Worked extensively on the gravitee-io/gravitee-kubernetes-operator repository, delivering robust end-to-end testing frameworks and infrastructure to support API management workflows on Kubernetes. Focused on automating lifecycle validation, expanding test coverage for v2 and v4 APIs, and integrating Terraform and Playwright-based tests for comprehensive resource verification. Leveraged Go, TypeScript, and YAML to build reusable test utilities, CI/CD pipelines, and platform-test documentation, while implementing upgrade survival checks and feature gating for version compatibility. Enhanced reliability through test suite refactoring, CI stability improvements, and detailed documentation, enabling faster feedback cycles and safer releases for complex API and operator upgrade scenarios.

May 1, 2026May 2026 focused on strengthening end-to-end testing, expanding Terraform provider capabilities, and improving test visibility and stability for the Gravitee Kubernetes Operator. Delivered source-built E2E tests for the Gravitee Terraform provider, expanded API key plan subscription coverage, and hardened the test harness to mitigate timeouts and cold-start flakes, with tests re-enabled after APIM upgrade. Introduced Group and GroupMember support with dedicated e2e coverage, leveraging mAPI helpers to enable comprehensive provider lifecycle tests. Expanded dictionary lifecycle and templating tests with richer fixtures and traceability, aligning test tags with real Jira tickets for end-to-end traceability. Implemented test results reporting automation by transforming Playwright JUnit results to Xray JSON and pushing results to Xray Cloud from CircleCI. Implemented stability workarounds for missing API CRD fields and pre-warmed Automation API to reduce cold-start impact, while re-enabling notification tests after API version prerequisites were met. Core technologies demonstrated include Terraform provider development and E2E testing, Playwright, mAPI integrations, CircleCI workflows, and Jira/Xray reporting.

Nov 1, 2024Month: 2024-11 This period focused on improving reliability and clarity around API member management in the Gravitee Kubernetes Operator, with targeted test coverage and small but meaningful documentation improvements. Key features delivered: - API Member Management Test Coverage: Added integration tests for managing API members in v4 APIs. Tests cover creating an API with a member who has no initial role, updating a member's role, and removing a member. This strengthens validation of API member management within the Gravitee Kubernetes operator. Commit: 9796ea23e0dfbf2f10d33d4cb19b7756d7247252. Major bugs fixed: - Documentation improvements for JWT plan subscribe use case: Fixed minor typographical errors in README.md to improve clarity and readability for the subscribe-to-jwt-plan flow. Commit: ef4527786a081237512a43d7f30efb5841919f20. Overall impact and accomplishments: - Increased test coverage for critical API member management flows, reducing risk of regressions in production and accelerating safe changes to v4 API member handling. - Improved documentation clarity, reducing onboarding time for new contributors and customers integrating JWT plan subscriptions. Technologies/skills demonstrated: - Integration testing in a Kubernetes operator context and validation of v4 API member management flows. - Proficient use of Git for feature commits and documentation updates, with clear messages that reflect intent. - Attention to quality through test coverage expansion and documentation hygiene, contributing to overall product reliability and developer usability.
