 We run all the tests except the tests that appear in the lists `src/test/system_tests/ceph_s3_tests/s3-tests-lists` if you would like to add or remove a test you can edit those files (and then repeat the steps starting from 'Build Core And Tester Images (Noobaa-Core)' above).
 
+Some tests are marked to be skipped in the tests code. usually because the enviorment doesn't support certain criteria. those tests will appear with a `[WARN]` tag and will be marked as "Test Skipped", for example:
+`[WARN] CONSOLE:: Test skipped: s3tests_boto3/functional/test_s3.py::test_lifecycle_transition`
+
+In the test code the function:
+`pytest.skip("")` will mark them to be skipped.

-Note: If you want to ignore PythonDeprecationWarnings use (which will then ignore all Python warnings, so keep that in mind):
-```bash
-export PYTHONWARNINGS="ignore"

+Note: If you want to ignore PythonDeprecationWarnings add the following flag to the test command (which will then ignore all Python warnings, so keep that in mind):
+`-- --disable-pytest-warnings`
+
+note that every flag that comes after `--` is past to pytest from tox. so if there is already `--` in the command just put `--disable-pytest-warnings` as part of the flags after it, no need to add another `--` notation.
+
+for example to add --disable-pytest-warnings to the command:
+`S3TEST_CONF=${PWD}/src/test/system_tests/ceph_s3_tests/test_ceph_s3_config.conf tox -c src/test/system_tests/ceph_s3_tests/s3-tests/tox.ini -- -m 'not fails_on_aws' ${PWD}/src/test/system_tests/ceph_s3_tests/s3-tests/s3tests_boto3/functional/test_s3.py::test_account_usage`

 ### 5) Run a Test (Inside The Tester Pod)
 To run a test, from noobaa working directory:
 ```bash
-S3TEST_CONF=$PWD/src/test/system_tests/ceph_s3_tests/test_ceph_s3_config.conf tox -c src/test/system_tests/ceph_s3_tests/s3_tests/tox.ini $PWD/src/test/system_tests/ceph_s3_tests/s3-tests/<test_name>

 ```
 This should run the test on the noobaa deployment we've set up.
 
 #### Test Name

 You can edit the test by going to the test file and editing the test function. e.g. if you are working on test `s3tests_boto3.functional.test_s3:test_set_bucket_tagging` then you should `vi ./src/test/system_tests/ceph_s3_tests/s3-tests/s3tests_boto3/functional/test_s3.py` and search for the function `test_set_bucket_tagging`.

 Prerequisites:
 Following the 'Run a Single Ceph S3 Test' steps until 'Deploy The Tester Deployment (Noobaa-Core Tab)'.
 
 In this section we will do some manual changes that will allow you to check AWS response for a specific test (tests that do not use neither ACL nor tenant group).
 1) copy configuration file:
   ```bash
-  cp .src/test/system_tests/ceph_s3_tests/test_ceph_s3_config.conf .src/test/system_tests/ceph_s3_tests/test_ceph_s3_config.conf.aws

+2) Change the new configuration file to match AWS details, `vi src/test/system_tests/ceph_s3_tests/test_ceph_s3_config_aws.conf`:
 * host = s3.amazonaws.com
 * bucket prefix = choose_name (for example: `bucket prefix = foo-bucket` you will need to manually delete it from AWS, and its name will be `foo-bucket1`, it adds suffix of 1).
 * access_key, secret_key appears 3 times each in the file.
 3) Running tests with the new configuration files will run against AWS:
 ```bash
