A453 OCR Computing Test plan help?

I 'm currently doing my course work and was wondering if anyone can give and advise on 'systematic testing'? Like can anyone give me examples please?
Also, For y test plan the columns i've done are test number, purpose, expected outcome ,validation and did it work. Then if the test didn't work I just said refer to error number... and in the pages after i just annotated errors and resolutions. I've also annotated each stage of my code. Is this alright or development?

I just need help on meeting the systematic testing criteria tbh. like what does it even mean? And i've seen others do e actual outcome Do i just copy and paste the test plan table near the end of the development and add an extra actual outcome column?
