## General
It is possible to check if an value is in a snapshot. The value of the generated snapshot will be a list of all values which are tested.
Example:
=== "original code"
<!-- inline-snapshot: first_block outcome-passed=1 outcome-errors=1 -->
``` python
from inline_snapshot import snapshot
def test_something():
s = snapshot()
assert 5 in s
assert 5 in s
assert 8 in s
for v in ["a", "b"]:
assert v in s
```
=== "--inline-snapshot=create"
<!-- inline-snapshot: create outcome-passed=1 outcome-errors=1 -->
``` python hl_lines="5"
from inline_snapshot import snapshot
def test_something():
s = snapshot([5, 8, "a", "b"])
assert 5 in s
assert 5 in s
assert 8 in s
for v in ["a", "b"]:
assert v in s
```
## pytest options
It interacts with the following `--inline-snapshot` flags:
- `create` create a new value if the snapshot value is undefined.
- `fix` adds a value to the list if it is missing.
- `trim` removes a value from the list if it is not necessary.
