The document describes testing of six modules across different operating systems and virtual machines. It provides 15 test cases to test cold reboot, warm reboot, and migration of systems, virtual machines, and virtual machine monitors based on time and memory thresholds. The test cases were executed on various dates and operating systems and results were recorded in tables showing test case ID, purpose, inputs, outputs, and execution history.

TESTING
5.1 Testing
There are essentially three main domain and six modules in our project. In this section the results
of all six modules are being tested with different OS, VM or VMM.
The purpose of this section is to ensure that the resulting system meets the system requirements
and there is a seamless transition of data flowing through each of the systems as well as in
between one another.
These testing provide a sort of "living document". Clients and other developers looking to learn
how to use the module can look at these tests to determine how to use the module to fit their
needs and gain a basic understanding of the API.
5.2.1 Testing Strategy
The following points are indicative of the testing strategy for unit testing followed in the project.
 Review the design specifications and source code for moules to be tested.
 Perform a peer review on the module Test Plan.
 Create any test "stubs" required to provide input to or receive output from the code
module.
 When it's time to test particular modules, compile the code in the test environment to
check for any missing files required for test plan execution.
 Execute the tests. Compare information/values received out of the tested software to
those expected, as documented in the Test Plan.
 Retest code when an updated version is available. Record results on the module Test
Report Form.
 When the module is considered to have passed all tests, archive the final Report form(s).
