-CODE\_GENERATOR Java serializer and formatter
-
-UTILITY Contains utility methods used by other modules
-
-JSON\_GENERATOR Interactive module to generate the configuration files
-(default names are "chains.json" and "config.json") "chains.json"
-describes all the chains of nodes belonging to a certain scenario
-
-TEST\_CLASS\_GENERATOR Generates one or multiple test scenarios given
-the two configuration files above (default names are "chains.json" and
-"config.json") All the test scenarios have to be placed in the examples
-folder (i. e. under "j-verigraph/service/src/tests/examples"). Here is
-the script help:
-
-test\_class\_generator.py -c -f -o
-
-Supposing the module gets executed from the project root directory (i.e.
-"j-verigraph"), a sample command is the following:
-
-service/src/tests/j-verigraph-generator/test\_class\_generator.py -c
-"service/src/tests/j-verigraph-generator/examples/budapest/chains.json"
--f
-"service/src/tests/j-verigraph-generator/examples/budapest/config.json"
--o "service/src/tests/examples/Scenario"
-
-Keep in mind that in the previous command "Scenario" represents a prefix
-which will be followed by an underscore and an incremental number
-starting from 1, which represents the n-th scenario starting from the
-previously mentioned "chains.json" file (this file can indeed contain
-multiple chains).
-
-TEST\_GENERATOR Generates a file which performs the verification test
-through Z3 (theorem prover from Microsoft Research) given a certain
-scenario generated with the above snippet. All the test modules have to
-be placed under the "tests" directory (i.e. under
-"j-verigraph/service/src/tests"). Here is the module help:
-
-test\_generator.py -i -o -s -d
-
-Supposing the module gets executed from the project root directory (i.e.
-"j-verigraph") a sample command given the previously generated scenario
-is the following:
-
-service/src/tests/j-verigraph-generator/test\_generator.py -i
-service/src/tests/examples/Scenario\_1.java -o
-service/src/tests/Test.java -s user1 -d webserver
-
-The aforementioned "Test.java" file can be compiled and executed
-normally. Its output will be either "SAT" or "UNSAT". For possible
-statistics the test is repeated 10 times and the average execution time
-in seconds is printed to the console.
