Running the tests

There are two options to run the tests, which are concrete execution and symbolic execution. Before running the test you have to choose an option. There is a global variable named UNIT_TEST in global_test_params.py to set the type of the tests.

# Testing concrete execution
UNIT_TEST = 2
# Testing symbolic execution
UNIT_TEST = 3

# Start testing
$ python oyente/run_tests.py

After running the testing program, the result would display a status for each testcase:

• PASS: the testcase passes
• FAIL: an opcode implements incorrectly
• TIME_OUT: it takes too long to run the testcase (set GLOBAL_TIMEOUT_TEST in global_params.py)
• UNKNOWN_INSTRUCTION: there is an unknown opcode in the testcase
• EXCEPTION: the program encounters an exception while running the testcase
• EMPTY_RESULT the result is invalid
• INCORRECT_GAS the gas is calculated incorrectly
