The processor is configured to generate a test scheme and execute a test corresponding to the test scheme; obtain a labeled test scheme; determine, based on the labeled test scheme, test data of the labeled test scheme; determine, based on the test data, whether an extended test is added; in response to determining that the extended test is added, adjust, based on the test data obtained from the storage module, a sampling frequency of a data monitoring module, and determine a test parameter of a newly added extended test; generate, based on the test parameter of the newly added extended test and an adjusted sampling frequency, a new test scheme.

Abstract: The present invention discloses a travel case for use as a work table. The travel case is adapted to operate in two modes including a default mode, and a table mode. During default mode, the travel case is configured to function as a conventional travel case and during table mode, the travel case is configured to stand on four legs to use a case body as a horizontal support surface. The table mode is configured to allow for easy access for unpacking and packing the travel case. The travel case comprises a release switch to activate any of the default mode or table mode. The downward movement of the release switch releases the internal mechanism and opens the four legs to a stable stance. The four legs are folded to its initial position to convert the travel case from travel mode to default mode.
