1. A computerized method for saving and restoring initialization actions on a device under test (DUT) and a corresponding test environment, the method comprising:

using a computer, executing a first simulation test comprising a DUT part for testing a DUT and a test environment part for testing a corresponding test environment;

using the computer, saving a snapshot image of the DUT and of the corresponding test environment upon completion of the initialization actions to configure the DUT that are included in the first simulation test;

using the computer, compiling a DUT part of a second simulation test for testing the DUT into the saved snapshot image of the DUT to obtain a restore image for the DUT;

using the computer, loading the restore image of the DUT and restoring the snapshot image of the test environment;

using the computer, loading a test environment part of the second simulation test; and

using the computer, executing the second simulation test on the DUT and corresponding test environment.
