   A financial services company automates end-to-end tests for a trading application. The test environment consists of: a dedicated application server, a shared database that also serves the development team, a network with a firewall that is occasionally reconfigured, and test data that is generated by a third-party data provider.

   • AIncrease test timeouts and retry failed tests
   • BRun tests only during off-peak hours
   • CUse a dedicated database, mock the third-party data provider, and coordinate firewall changes
   • DUse a dedicated application server and ignore the other dependencies
