PROCEDURE
PRESENTATION TITLE 32
A TEST PROCEDURE IS A SET OF STEPS TO
GUIDE YOU THROUGH WHAT NEEDS TO BE
DONE TO THOROUGHLY TEST THE
INSTALLATION. IT IS DESIGNED TO HELP
YOU WORK MORE EFFECTIVELY AND TO
MAKE SURE YOU TEST EVERYTHING THAT
NEEDS TESTING. TEST PROCEDURES ARE
CREATED IN-HOUSE AND COULD INCLUDE
THESE STEPS
PRESENTATION TITLE 33
GATHERING TEST INFORMATION.
THE FIRST STEP IS TO RUN THE TESTS
REQUIRED BY THE PROCEDURE AND FIND
OUT WHAT HAPPENS. YOU SHOULD
RECORD ALL THE RESULTS OF YOUR TESTS
IN A LOG SO THAT YOU KNOW WHICH PASS
AND WHICH FAIL, THEREBY REQUIRING
FURTHER ACTION.
1 PRESENTATION TITLE 34
VALIDATING THE TEST
INFORMATION.
THE NEXT STEP IS TO CHECK THE DATA
YOU GATHERED FROM THE TESTS TO
MAKE SURE IT IS CORRECT. THIS IS
USUALLY DONE BY RUNNING THE
TESTS AGAIN.
2 PRESENTATION TITLE 35
THIS STEP IS IMPORTANT BECAUSE YOU
NEED TO BE ABLE TO RECOGNIZE WHEN A
TEST SHOWS PROBLEMS OR IS
SUCCESSFUL. FOR EXAMPLE, IF PING IS
USED TO TEST A NETWORK CONNECTION
THEN ‘REQUEST TIMED OUT’ SHOWS THE
TEST WAS NOT SUCCESSFUL.
3 PRESENTATION TITLE 36
RESPONDING TO TEST
INFORMATION.
THE FINAL STEP IS AN IMPORTANT END TO
TESTING. YOU NEED TO CHECK THE
SPECIFICATION FOR THE INSTALLATION TO
MAKE SURE THAT IT HAS BEEN MET. FOR
EXAMPLE, IF A USER REQUESTED AN
UPGRADE TO MAKE THEIR DISPLAY RUN AT
1920 X 1200, THEN THE ICT PROFESSIONAL
SHOULD CHECK THAT THE GRAPHICS CARD
AND SCREEN CAN DO THIS.

Editor's Notes

  • #5 As computer technician you will need a good understanding of the health and safety regulations from early on in your career, so that you understand the good practices demanded by law. In particular, you need to:  report any accidents   take reasonable care of your own health and safety when moving heavy components   not cause any electrical hazards   make sure that workstations meet safety requirements.   You need to adhere to health and safety regulations as they will help to protect you and others and will avoid any unnecessary legal action for reckless and unsafe working practices. If you identify any health and safety problems, you should tell your line manager or the health and safety representative immediately. The most basic test is to switch the system on to check it starts without errors. ICT professionals are also likely to use tools and utilities to check that all is well with the system after an installation.
