Building a Maestro Plugin for IntelliJ: From Mobile Test Automation to IDE Excellence
Article Summary
Trendyol's mobile team turned Maestro test automation from a terminal-only workflow into a full-featured IDE experience. Writing YAML tests without syntax highlighting, validation, or auto-complete was slowing everyone down.
The team built an open-source IntelliJ plugin that brings first-class IDE support to Maestro's YAML-based mobile UI tests. The plugin leverages IntelliJ's existing YAML infrastructure while adding Maestro-specific intelligence on top.
Key Takeaways
- Context-aware auto-completion suggests valid commands based on current file position
- Real-time validation catches conflicts like combining incompatible parameters before runtime
- Jump-to-definition works across YAML flows and JavaScript helper files seamlessly
- Custom process listener parses Maestro console output into IDE test runner format
- Two-layer file detection uses path patterns and content scanning with caching
Critical Insight
The plugin transforms Maestro testing from a context-switching workflow into a native IDE experience with intelligent completions, inline validation, and one-click test execution.
