What is parallel test execution in Selenium?<\/strong><\/h5>\n<p data-start=\"879\" data-end=\"1035\">Parallel test execution means running multiple tests simultaneously across different nodes or browsers to reduce total execution time and speed up feedback.<\/p>\n<h5 data-start=\"1037\" data-end=\"1094\"><strong data-start=\"1041\" data-end=\"1092\">2. Why use Selenium Grid with Azure Kubernetes?<\/strong><\/h5>\n<p data-start=\"1095\" data-end=\"1261\">Azure Kubernetes (AKS) gives elastic scaling, pod isolation, resiliency, and automated node management, solving limitations of traditional local Selenium Grid setups.<\/p>\n<h5 data-start=\"1263\" data-end=\"1317\"><strong data-start=\"1267\" data-end=\"1315\">3. How does AKS improve Selenium test speed?<\/strong><\/h5>\n<p data-start=\"1318\" data-end=\"1462\">AKS spins up multiple pods to run tests in parallel, cutting regression time from hours to minutes while handling browser scaling automatically.<\/p>\n<h5 data-start=\"1464\" data-end=\"1526\"><strong data-start=\"1468\" data-end=\"1524\">4. What challenges occur in parallel test execution?<\/strong><\/h5>\n<p data-start=\"1527\" data-end=\"1688\">Common challenges include flaky tests, data conflicts, logging complexity, and shared state issues\u2014all solvable with isolation, centralized data, and good waits.<\/p>\n<h5 data-start=\"1690\" data-end=\"1753\"><strong data-start=\"1694\" data-end=\"1751\">5. Does parallel execution work with CI\/CD pipelines?<\/strong><\/h5>\n<p data-start=\"1754\" data-end=\"1894\">Yes.
