# Test Case: Repeated Positive Lookup Behavior
|
|
|
|
**Test ID**: TC051-namecache-hit
|
|
**Category**: VFS Integration
|
|
**Priority**: High
|
|
|
|
## Objective
|
|
|
|
Verify repeated positive pathname lookups remain stable within one mount.
|
|
This is behavior-level namecache integration coverage; timing differences do
|
|
not prove an internal cache hit.
|
|
|
|
## Procedure
|
|
|
|
Mount vfs/vfs-plain.erofs and run:
|
|
|
|
stat -f 'ino=%i mode=%p size=%z gen=%v' \
|
|
/tmp/repo22-g3/mnt/testdir/file.txt > TC051-first.txt
|
|
stat -f 'ino=%i mode=%p size=%z gen=%v' \
|
|
/tmp/repo22-g3/mnt/testdir/file.txt > TC051-second.txt
|
|
cmp TC051-first.txt TC051-second.txt
|
|
cmp fixtures/vfs/source/testdir/file.txt \
|
|
/tmp/repo22-g3/mnt/testdir/file.txt
|
|
|
|
## Expected Results
|
|
|
|
Both lookups succeed with byte-identical metadata and data. Record only this
|
|
observable behavior as PASS; do not claim a measured cache hit without kernel
|
|
instrumentation. Record output and cleanup.
