# Test Case: Sequential Regular-File Read
|
|
|
|
**Test ID**: TC035-file-read-sequential
|
|
|
|
## Objective
|
|
|
|
Verify buffered sequential reads return every byte of a deterministic
|
|
multi-block regular file.
|
|
|
|
## Fixture
|
|
|
|
Use `images/flat.erofs` and `source/flat/data.txt`. Evidence asserts
|
|
`FLAT_PLAIN`, NID, and size 262163.
|
|
|
|
## Procedure
|
|
|
|
```sh
|
|
stat -f 'size=%z blocks=%b' "$mnt/data.txt"
|
|
dd if="$mnt/data.txt" of=/tmp/tc035.out bs=4096
|
|
cmp /tmp/repo22-g1/source/flat/data.txt /tmp/tc035.out
|
|
sha256 /tmp/repo22-g1/source/flat/data.txt /tmp/tc035.out
|
|
```
|
|
|
|
Remove output, unmount, and detach.
|
|
|
|
## Expected Results
|
|
|
|
- `dd` reaches exact EOF and the complete output matches the source/hash.
|
|
- No short read, data corruption, dmesg error, or cleanup failure occurs.
