Figure 1: ALCA free drive directory structure

Directory/File	Description
test_suites	A directory that contains the following folders to execute multiple tests: The test_suite_definitions folder contains the CSV files for executing ALCA free drive tests with FRun The templates folder is used to generate tests to be executed with FRun The example_test_cases folder contains test cases to run the ALCA free drive scenarios
scenarios	A directory containing the OSC2 source files for each scenario

427.1 Running a regression

To run a set of tests with FRun:

Invoke FRun in batch mode with all the CSV files required for the set of tests that you chose.

For example:

frun --csv $FTX_PACKAGES/adas/alca/test_suites/test_suite_definitions/free_drive/alca_free_drive.csv
 --csv $FTX_PACKAGES/adas/alca/test_suites/test_suite_definitions/free_drive/alca_free_drive_main.csv
 --csv $FTX_PACKAGES/common/csv/sim_manually_driven_kinematic_config.csv
 --csv $FTX_PACKAGES/common/csv/new_map_config.csv
 --batch

Review the regression results in the default work directory.
