Just going through few projects provided by Microsoft for sharepoint 2013 developers I seen requirements for development tools, it says
This sample requires the following:
Visual Studio 2012 SharePoint development tools in Visual Studio 2012 A SharePoint 2013 Preview development environment
I installed sharepoint server 2013 but my laptop only has 4 GB ram so I couldn't test it much, how can I test developed sharepoint 2013 apps/solutions by me and if I can develop them without having sharepoint server.
