# Run AIQ Tests Across Windows and Linux Machines **Last reviewed:** September 28, 2026 Use this article when planning Scenario Editor or execution-node coverage across mixed Windows and Linux machines. ## What changed in this article - Corrected the title grammar and changed the answer from a one-off FAQ into mixed-node execution guidance. - Added practical compatibility checks for browser versions, drivers, filesystem paths, node labels, environment variables, and OS-specific dependencies. - Clarified that mixed OS execution is valid only when the scenario and test data do not rely on OS-specific assumptions. ## Validation workflow 1. Identify which nodes are Windows and which are Linux, including browser and driver versions. 2. Review the scenario for OS-specific paths, shell commands, downloads, or file permissions. 3. Run a small node-targeted execution on each OS before scheduling a full mixed run. **Review note:** Added node-readiness validation so mixed Windows/Linux execution does not hide environment-specific failures. --- Last updated: September 28, 2026 If you have feedback on this topic, contact .
