S3 compatibility tests
========================
This is a set of completely unofficial Amazon AWS S3 compatibility
tests, that will hopefully be useful to people implementing software
that exposes an S3-like API.
The tests only cover the REST interface.
The tests use the Boto library, so any e.g. HTTP-level differences
that Boto papers over, the tests will not be able to discover. Raw
HTTP tests may be added later.
This is a set of unofficial Amazon AWS S3 compatibility
tests, that can be useful to people implementing software
that exposes an S3-like API. The tests use the Boto2 and Boto3 libraries.
The tests use the Nose test framework. To get started, ensure you have
the ``virtualenv`` software installed; e.g. on Debian/Ubuntu::
@ -22,76 +16,41 @@ and then run::
./bootstrap
You will need to create a configuration file with the location of the
service and two different credentials, something like this::
service and two different credentials. A sample configuration file named
``s3tests.conf.SAMPLE`` has been provided in this repo. This file can be
used to run the s3 tests on a Ceph cluster started with vstart.
[DEFAULT]
## this section is just used as default for all the "s3 *"
## sections, you can place these variables also directly there
## replace with e.g. "localhost" to run against local software
host = s3.amazonaws.com
## uncomment the port to use something other than 80
# port = 8080
## say "no" to disable TLS
is_secure = yes
[fixtures]
## all the buckets created will start with this prefix;
## {random} will be filled with random characters to pad
## the prefix to 30 characters long, and avoid collisions
bucket prefix = YOURNAMEHERE-{random}-
[s3 main]
## the tests assume two accounts are defined, "main" and "alt".
## user_id is a 64-character hexstring
user_id = 0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef
## display name typically looks more like a unix login, "jdoe" etc
display_name = youruseridhere
## replace these with your access keys
access_key = ABCDEFGHIJKLMNOPQRST
secret_key = abcdefghijklmnopqrstuvwxyzabcdefghijklmn
## replace with key id obtained when secret is created, or delete if KMS not tested
kms_keyid = 01234567-89ab-cdef-0123-456789abcdef
[s3 alt]
## another user account, used for ACL-related tests
user_id = 56789abcdef0123456789abcdef0123456789abcdef0123456789abcdef01234
display_name = john.doe
## the "alt" user needs to have email set, too
email = john.doe@example.com
access_key = NOPQRSTUVWXYZABCDEFG
secret_key = nopqrstuvwxyzabcdefghijklmnabcdefghijklm
Once you have that, you can run the tests with::
Once you have that file copied and edited, you can run the tests with::
S3TEST_CONF=your.conf ./virtualenv/bin/nosetests
You can specify which directory of tests to run::
S3TEST_CONF=your.conf ./virtualenv/bin/nosetests s3tests.functional
You can specify which file of tests to run::
S3TEST_CONF=your.conf ./virtualenv/bin/nosetests s3tests.functional.test_s3
You can specify which test to run::
S3TEST_CONF=your.conf ./virtualenv/bin/nosetests s3tests.functional.test_s3:test_bucket_list_empty
To gather a list of tests being run, use the flags::
-v --collect-only
You can specify what test(s) to run::
S3TEST_CONF=your.conf ./virtualenv/bin/nosetests s3tests.functional.test_s3:test_bucket_list_empty
Some tests have attributes set based on their current reliability and
things like AWS not enforcing their spec stricly. You can filter tests
based on their attributes::
S3TEST_CONF=aws.conf ./virtualenv/bin/nosetests -a '!fails_on_aws'
Most of the tests have both Boto3 and Boto2 versions. Tests written in
Boto2 are in the ``s3tests`` directory. Tests written in Boto3 are
located in the ``s3test_boto3`` directory.
TODO
====
You can run only the boto3 tests with::
- We should assume read-after-write consistency, and make the tests
actually request such a location.
http://aws.amazon.com/s3/faqs/#What_data_consistency_model_does_Amazon_S3_employ
S3TEST_CONF=your.conf ./virtualenv/bin/nosetests -v -s -A 'not fails_on_rgw' s3tests_boto3.functional
- Test direct HTTP downloads, like a web browser would do.

Unit-test suite for the S3 fuzzer
The fuzzer is a grammar-based random S3 operation generator

It works by running the fuzzer off of a simple grammar,
