usbinterop1.pl - Create directories and files, read back and compare |
|
303 |
||
304 |
=head1 SYNOPSIS |
|
305 |
||
306 |
usage: usbinterop1.pl [options] |
|
307 |
||
308 |
=head1 OPTIONS |
|

=over 4 |
|
311 |
||
312 |
=item --spread=<number of directories and files> |
|
313 |
||
314 |
Spread is the number of directories and files that are created at each |
|
315 |
level of the created tree. For example, a spread of three would |
|
316 |
create three directories and three files in each of the directories. |
|
317 |
Spread is a measure of the "bushiness" of the directory tree. |
|
318 |
||
319 |
Default value is "3". |
|
320 |
||
321 |
=item --depth=<directory nesting level> |
|
322 |
||
323 |
Each directory can have subdirectories up to the limit of the depth |
|
324 |
parameter. Depth is a measure of the "height" of the directory tree. |
|
325 |
||
326 |
Default value is "1". |
|
327 |
||
328 |
=item --size=<size of files to create> |
|
329 |
||
330 |
The size in bytes for each test file. Be careful as the disk space |
|
331 |
used is a function of this parameter as well as the depth and spread |
|
332 |
parameters: |
|
333 |
||
334 |
total size = size*(sp^(dep+1)+sp^(dep)+sp^(dep-1)+..+sp^2) |
|
335 |
||
336 |
Default value is "1024". |
|
337 |
||
338 |
=item --drive=<USB drive location> |
|
339 |
||
340 |
The path to the USB drive in which to write the files. |
|
341 |
||
342 |
Default value is ".", the current working directory. |
|
343 |
||
344 |
=item --read=<0/1> |
|
345 |
||
346 |
0 to write |
|
347 |
1 to read |
|
348 |
||
349 |
Default value if no option given is 0 (write). |
|
350 |
||
351 |
Ensure the card/device has been ejected and thus flushed before you do the |
|
352 |
reading test after the writing case, otherwise the content will be cached by |
|
353 |
the local OS and the time measured won't be realistic. |
|
354 |
||
355 |
'Write' will leave the transferred files on the remote disk, but 'Read' will |
|
356 |
delete them (moving them to the local PC). So a practical test order is: |
|
357 |
||
358 |
'Write' test, then disconnect/re-connect USB drive, then 'Read' test. |
|
359 |
||
360 |
This sequence will start and finish with an empty USB disk. |
|
361 |
||
362 |
=item --logfile=<file> |
|
363 |
||
364 |
Append test output to specified file. |
|
365 |
||
366 |
=item --help=<file> |
|
367 |
||
368 |
Displays this help. |

=head1 DESCRIPTION |
|
373 |
||
374 |
This is a simple utility to create folders and files with varying |
|
375 |
levels of nesting and sizes on a USB drive, and read them back to |
|
376 |
verify their contents. |
|
377 |

=head2 Test Case Specification |
|
379 |
||
380 |
TestCaseID: Interoperability_1 |
|
381 |
TestType: IT |
|
382 |
TestCaseDesc: Test Mass Storage functionality on different platforms |
|
383 |
(Windows 2000/XP/ME, MacOS) (Manual test) |
|
384 |
FssID: Base/emstore/1.1.1 |
|

FssID: Base/emstore/3.1.1 |
|
386 |
||
387 |
TestActions: |
|
388 |
Connect device to a host PC. Enable MS. Start perl script on |
|
389 |
PC. This script formats drive and creates several folders with |
|
390 |
levels of nested folders and writes set of files to them. File sizes |
|
391 |
varied from several kilobytes to several megabytes. The number of |
|
392 |
folders, nest depth, number of files placed in each folder and there |
|
393 |
sizes should be configurable. Then script prompt ask to unplug/plug |
|
394 |
USB cable (to flash OS read cache) and then read all files back and |
|
395 |
compare. |
|
396 |
||
397 |
TestExpectedResults: |
|
398 |
Read data from files should match with written. |
