@rajateshr We have Jenkins builds for almost all branches and did not seem to have this issue. I think it maybe an environment or setup issue. Have you gone through steps documented in https://github.com/magento/magento2-functional-testing-framework/blob/develop/docs/getting-started.md before running the test?
