Test Automation of SolutionBuilder applications: Running e2e for Hotfixes

To run e2e tests for Hotfix do the following:

1. Get release branch sources from VSTS (e.g. c:\dev\9.1.0)
2. Get binaries by running UpdateContinuousBuildBinaries.cmd (e.g. c:\dev\9.1.0\UpdateContinuousBuildBinaries.cmd)
3. Install the application if you haven't prepared Hotfix for this release before otherwise run Deployment.SwitchEnvironment.cmd (e.g. c:\dev\9.1.0\Deployment.SwitchEnvironment.cmd)
4. Compile the changed solution (if needed)
5. If needed create a frontend distribution build and replace files (except config.json) under WM folder (e.g. c:\dev\9.1.0\Root\WM)
6. Check out the respective release branch of the ProtractorUITest repository (e.g. release-9.1.0.0)
7. Run `npm install`
8. Run `collect:objects` gulp task
9. Run needed e2e tests
