a processor; and

a memory system accessible by said processor, wherein said memory system stores a set of computer-readable instructions that permit said processor to execute a method of testing an application program, said set of computer-readable instructions comprising:

performing a static analysis of metadata of code of an application, using a test application program executed by a processor on a computer;

simulating the application code to determine available user interface states of said application based on said static analysis of the metadata of the code of the application;

accessing and parsing a configuration file of said application to enumerate states possible for said application, wherein the accessing and parsing the configuration file includes parsing and enumerating a plurality of different views of the configuration file;

calculating a coverage metric for said application based on a difference between a number of the states reached by said simulating of said available user interface states and a number of states possible as enumerated from said configuration file;

determining which possible states are missing when said simulating is completed according to the metadata of the code of application; and

comparing the number of states reached during the simulation with the number of states possible, including calculating one or more coverage values,

wherein the user interface states in a code under testing are simulated based on the static analysis of the metadata.
