# Script Author : Shantha Condamoor # Main FSW Package: LFS # FSW Package Author : Dan Wood # Test Type: 002b # Test Procedure: File Management and Memory Upload and Dump Verification # Test Name: File Delete # Requirement: 5.3.7.3 # In order to delete a file, the FSW shall receive as input, from the spacecraft via the CTDB, # a command that includes file identifier, directory identifier, device identifier, and unit identifier. # # system 0 - testbed host # system 1 - Spacecraft/1553 bus controller # # Test Preconditions: 1) This script CANNOT be run in the BOOT mode as LFS commands are currently unsupported in this mode. # 2) Before this test script can be run, FSW on RAD750 SIU crate must have undergone Primary # and Secondary Boots, all Application Modules (including LFS and FILE) must have been loaded, # all tasks, including (FILE, ITC) must have been initialized and be running. # 3) Before this test script can be run, FSW on RAD750 EPU0 crate must have # undergone Primary and Secondary Boots, all Application Modules (including LFS and FILE) # must have been loaded and all tasks (including FILE and ITC) must have been initialized # and be running # 4) Before this test script can be run, test script dir_create (5_3_7_1) MAY # have been run successfully and Directory 111 MAY have been created. # 5) Before this test script can be run, test script file_load (5_3_7_9) MAY # have been run successfully and Files 1,2,3 and 4 MAY have been created in Directory 111. # 6) Before this test script can be run, test script file_copy_within_proc (5_3_7_4) MAY # have been run successfully and Files 1,2,3 and 4 MAY have been copied as Files 12 # and 13 into Directory 111 EEPROM0. # 5) Before this test script can be run, test script file_copy_within_proc (5_3_7_4) MAY # have been run successfully and Files 1,2,3 and 4 MAY have been copied as Files 12 # and 13 into Directory 111 EEPROM1. # 6) Before this test script can be run, test script file_copy_siu_to_epu (5_3_7_5) MAY # have been run successfully and Files 1,2,3 and 4 MAY have been copied to Directory 111 # in EPU0 EEPROM0. # 7) Before this test script can be run, test script file_copy_siu_to_epu (5_3_7_5) must # have been run successfully and Files 1,2,3 and 4 must have been copied to Directory 111 # in EPU0 EEPROM1. # Test Postconditions: 1) Test scripts file_copy_within_proc (5_3_7_4), file_copy_siu_to_epu (5_3_7_5) # and CANNOT be run after this test script has been run. # 2) Test script dir_delete (5_3_7_2) can be run only after this script has been run. # 3) Test scripts dir_dump (5_3_7_7), sys_status_dump (5_3_7_8) and file_dump (5_3_7_6) must be run after # this script has been run to verify that the files have been successfully deleted. # # Tests on both SIU and EPU0. # Tests on both banks: EEPROM0, EEPROM1 # Tests deletion of a file that has already been deleted. # Tests deletion of a file that does not exist. # Deletes all files that were created using other scripts. # ############################################################################################################### #
