View Source Test Assertions
Quokka rewrites test assertions to use the more idiomatic refute
macro where semantically appropriate.
Transformations
assert not
→ refute
Rewrites negated assertions to use the refute
macro:
# Before
assert not user.status == :active
assert not Process.alive?(pid)
# After
refute user.status == :active
refute Process.alive?(pid)
assert !
→ refute
Rewrites bang-negated assertions to use the refute
macro:
# Before
assert !user.active
assert !valid?
assert !result
# After
refute user.active
refute valid?
refute result
Membership Testing
A common pattern in tests is checking that elements are not in collections:
# Before
assert elem not in my_list
assert not (user in banned_users)
assert !(key in forbidden_keys)
# After
refute elem in my_list
refute user in banned_users
refute key in forbidden_keys
