Abstract
The present disclosure relates to automated testing of hardware and software systems. In some embodiments, a testing framework that generates a set of test cases for a system under test using a grammar is disclosed. The grammar may include terminal and nonterminal symbols with tags that describe a test sequence. The testing framework can use the grammar to generate a set of test cases. The testing framework can then receive feedback about the execution of the set of test cases from the system under test. In response to the feedback, the testing framework can generate a new set of grammars by automatically modifying or inserting tags in the original grammar. The new set of grammars can then be used to generate further test cases that intelligently explore the system under test for correctness, conformance, performance, security, or reliability.
