Testing

1. Test Data Generator

The test data generator ocparse_generator can generate a large number of generic tests for common test and eunit tests. For this, the script test\gen_tests or test\gen_tests_and_run can be used. Both scripts first compile the Erlang modules and then generate the desired test files. The script test\gen_tests_and_run additionally performs the following tasks:

• running all Eunit tests,
• running all common tests,
• running the Erlang coverage tool for the folder utility.

The following environment variables can be used to control the test data generation process:

variable name	possible values	default value	description
GENERATE_COMPACTED	true, false	true	true: generates compact tests; false: generates detailed tests
GENERATE_CT	true, false	true	true: generates common tests
GENERATE_EUNIT	true, false	false	true: generates eunit tests
GENERATE_PERFORMANCE	true, false	false	true: generates performance tests, i.e. creates only parse tree and token list
GENERATE_RELIABILITY	true, false	false	true: generates reliability tests, i.e. creates the parse tree and recreates from this parse tree the original statement
LOGGING	true, false	false	true: creates special logging messages regarding ets processing and heap consumption
MAX_BASIC	any positive integer	250	determines the number of generated basic grammar objects

2. Stress Testing

The script test\stress_testt allows a stress test to be performed based on common test. The stress test can be started by calling test\stress_test n, where n indicates the required number of test runs. In each test run, the test data will be regenerated and subsequently launched with common test. Only the test suites with the prefix performance_ will be processed.
