If you try to run multiple selenium remote controls for IE on one machine it will work for a while.\u00a0\u00a0 Your test will execute without any problems, but then you start getting sporadic error messages from IE.\u00a0 I assumed that the xpath expressions I was using for the tests in Firefox were throwing errors in IE.\u00a0 I tried different configurations for security settings in IE for a while and then I finally found out that it was a memory sharing issue that prevents the selenium remote from launching more than one IE instance.\u00a0 For now I am just requesting more VMs to run a single IE remote on each.\u00a0 I use ruby with deep test to run test in parallel on the grid.\u00a0 I configure deep test to run 6 tests at a time, so I would only need 6 VMs for IE to run.<\/p>\n

It puzzling to me that Watin tests run in parallel against IE without any problems on the same machine, but selenium tests cannot.\u00a0 For now I will add more VMs and wait for Selenium Grid 1.2\u00a0 to fix the IE problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
