Saved snapshot fails to match if repr ends with newline #925
Description
Describe the bug
It appears that if you snapshot test against an object whose repr ends in a newline, then the test will fail even after running --snapshot-update
To reproduce
# test_syrupy.py
class X:
def __repr__(self):
return "X\n"
def test_syrupy(snapshot):
assert X() == snapshotThen run pytest test_syrupy.py --snapshot-update then pytest teest_syrupy.py
The test fails with the following output
test_syrupy.py F [100%]

_________________________________________________________________________________________________ test_syrupy __________________________________________________________________________________________________
snapshot = X
def test_syrupy(snapshot):
> assert X() == snapshot
E assert [+ received] == [- snapshot]
E - X
E + X
Expected behavior
I expect the test to pass
