Embedded device testing method using host virtualization and computing device executing the same

A computing device comprising:

• a processor;
• and
• a memory communicating with the processor,
• wherein the memory stores commands for causing the processor to perform operations, and
• the operations include;
• an operation of receiving, by a main host, setting information for an execution environment of a target device,
• an operation of determining, by the main host, a schedule of a test request of a user,
• an operation of allocating a sub host when the target device and the execution environment become available according to the determined schedule,
• an operation of constructing a virtualized execution environment on a sub host according to the setting information,
• an operation of executing specific software or a specific test case in the constructed execution environment, and
• an operation of monitoring a result of the execution via a log manager,
• wherein the operation of allocating of the sub host comprises determining a type of the virtualized execution environment based on a first threshold defining an isolation level and a second threshold defining a distribution level, which are set for the test case, and
• wherein the operation further comprises:
• updating the isolation level and the distribution level of the virtualized execution environment through the log manager to be applied when the virtualized execution environment is reused;
• and
• performing the reuse of the virtualized execution environment by at least one of:
• (i) utilizing an image uploaded to a registry for multi-user access, (ii) utilizing a script code defining environment settings for version management, or (iii) storing data external to a container for data persistence.
