Method, system, and framework for testing a human machine interface (HMI) application on a target device

A system for testing a human machine interface (HMI) application on a target device, the system comprising:

• a host service delivery platform (HSDP) comprising at least one processor and a computer-readable medium storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• accessing a test script corresponding to a test case for testing the HMI application on the target device, wherein the test script comprises a set of primitive executables, and wherein each of the set of primitive executables is configured to simulate at least one of a trigger or a condition corresponding to a business logic (BL) component of the HMI application and to verify an output using at least one of a view component or a platform component of the HMI application, and wherein primitive executables of the set of primitive executables are mutually independent,
• wherein the test script is automatically generated by determining the set of primitive executables from among a plurality of primitive executables based on trigger-guard-action information available for each state in the BL component of the HMI application,
• wherein determining the set of primitive executables from among the plurality of primitive executables comprises:
• determining a possible trigger for a current state by querying the BL component of the HMI application;
• executing a first subset of appropriate primitive executables to simulate the possible trigger;
• determining next state based on the current state and the possible trigger;
• executing a second subset of appropriate primitive executables to simulate a negative condition and verifying when there is an appropriate effect or no effect on an outcome of an execution of the test script;
• executing a third subset of appropriate primitive executables to simulate a positive condition and verifying when there is an appropriate effect on the outcome of the execution of the test script;
• and
• verifying the outcome of the execution of the test script using at least one of the view component or the platform component of the HMI application;
• transmitting each of the set of primitive executables to the target device for execution;
• and
• receiving a result corresponding to the execution of the each of the set of primitive executables.

A non-transitory computer-readable medium storing computer-executable instructions for:

• accessing a test script corresponding to a test case for testing the HMI application on the target device, wherein the test script comprises a set of primitive executables, and wherein each of the set of primitive executables is configured to simulate at least one of a trigger or a condition corresponding to a business logic (BL) component of the HMI application and to verify an output using at least one of a view component or a platform component of the HMI application, and wherein primitive executables of the set of primitive executables are mutually independent,
• wherein the test script is automatically generated by determining the set of primitive executables from among a plurality of primitive executables based on trigger-guard-action information available for each state in the BL component of the HMI application,
• wherein determining the set of primitive executables from among the plurality of primitive executables comprises:
• determining a possible trigger for a current state by querying the BL component of the HMI application;
• executing a first subset of appropriate primitive executables to simulate the possible trigger;
• determining next state based on the current state and the possible trigger;
• executing a second subset of appropriate primitive executables to simulate a negative condition and verifying when there is an appropriate effect or no effect on an outcome of an execution of the test script;
• executing a third subset of appropriate primitive executables to simulate a positive condition and verifying when there is an appropriate effect on the outcome of the execution of the test script;

• verifying the outcome of the execution of the test script using at least one of the view component or the platform component of the HMI application;
• transmitting each of the set of primitive executables to the target device for execution;
• and
• receiving a result corresponding to the execution of the each of the set of primitive executables.
