Getting started

Configure

var testServerOptions = new TestServerOptions
{
    // Looks for the newest version on your machine including 3.1.15 and any newer patches
    // but not major new releases (default is .NET version at time of server release).
    FrameworkVersion = "3.1.15+",

    // Specifies where ravendb server binaries are located (Optional)
    ServerDirectory = "PATH_TO_RAVENDB_SERVER",

    // Specifies where ravendb data will be placed/located (Optional)
    DataDirectory = "PATH_TO_RAVENDB_DATADIR", 
};

ConfigureServer(testServerOptions);
