Test Plan
Functionality Testing
- 1.0 WebDAV upload/download files and folders on all platforms to MyWorkspace, course, and project sites
- 1.1 Test DropBox
- 1.2 Test Melete
- 1.3 Connect from different systems with different user accounts, e.g. sakaistu1, etc.
- 1.3.1 Test Chat. Chat messages should show up automatically approximately after 10 seconds
- 1.3.2 Test Message Center. Send messages and others should see them after a forum/topic refresh.
Setup and Configuration Testing
- The load balancer keeps track of the client to node forwarding information in a table for
one hour (60 minutes). What happens after 60 minutes? Does the client still connect to the
same node? For example, what happens if a student takes a quiz in Samigo and the client to
node mapping gets reset? Should the Sakai session match the load balancer's "session" timeout?
