Correctness of volume identifier, sizes of used and free spaces, capacity.This option also creates additional test surroundings - compressed\ not compressed NTFS disk - for testing of file operations. Change properties of data compression for NTFS file systems on the fly in the disk properties:.Option of information compression during the formatting in NTFS systems (economy of disk space).And so we won’ be able to check up work on difficult transitions between the disk clusters. In fact if the file size will be less than 2 clusters (cell of MFT table) then the file will be fully placed in MTF table. It’s important when we choose file size for testing of the NTFS file system. Formatting with the non-standard size of a cluster.we already had the file system and files on a disk before formatting. Formatting of not empty disk with the new file system FAT\ NTFS.Formatting of empty disk with the new file system FAT\NTFS. Pay attention that all of disks are formatted with a standard (by default) cluster size. During this process user chooses the system to be created: FAT or NTFS. Our testing starts where the file system is created, namely in the moment of disk formatting. Exactly this list will help us in testing. It is not difficult to list them: to create, copy, move, rename, modify and delete. We can work better, but never worse.Īs experience shows, the operations are the first that occur when we start talking about the file systems and files. Therefore let’s believe that all readers have such knowledge.įirst let’s define the basic principle in our testing as following: the result of all actions must be the same to the one obtained when the operating system works without us. In the internet - and not only there - you can find a lot of sources on the file systems describing their type, structure, history and features. Thus, if the developed software does not handle the storing of user information then it is synonymous to failure. So corrupted or disappeared without trace file makes us, at least, not very happy. All necessary information is stored in files which we work with. Additional points from general testing principles.įile system is a part of the operating system. Testing of applications workings with the file systemsģ. In this article we will talk about the file systems and files, but the most attention will be focused on the key points of testing of software that works with NTFS and FAT file systems.Īt the end we will give our check list for testing of software, working with the FAT and NTFS file systems - we hope that it will help you in development of testing plan for your software.Ģ.
