Mastodon.py/tests

Running

To run this test suite, install the testing dependencies:

pip install -e .[test,webpush,blurhash]

Then, run pytest.

If you wish to check test coverage:

pytest --cov=mastodon

And if you want a complete HTML coverage report:

pytest --cov=mastodon --cov-report html:coverage
# then open coverage/index.html in your favourite web browser

Note that some tests are slightly unstable, as they require sidekiq to do things at the right time, and will thus sometimes break.

Contributing

This test suite uses VCR.py to record requests to Mastodon and replay them in successive runs.

If you want to add or change tests, you will need a Mastodon development server running on http://localhost:3000. To set this up, follow the development guide at https://docs.joinmastodon.org/dev/setup/ .

It also needs various things to be set up for it. The following command will do the trick:

sudo redis-cli flushall && sleep 3 && \
sudo /etc/init.d/redis-server restart && \
RAILS_ENV=development rails db:setup && \
RAILS_ENV=development bin/tootctl accounts create admin2 --email zerocool@example.com --confirmed --role Owner && \
RAILS_ENV=development bin/tootctl accounts create mastodonpy_test --email mastodonpy_test@localhost:3000 --confirmed && \
RAILS_ENV=development bin/tootctl accounts create mastodonpy_test_2 --email mastodonpy_test_2@localhost:3000 --confirmed && \
psql -d mastodon_development < ~/masto/Mastodon.py/tests/setup.sql && sleep 4 && \
RAILS_ENV=development DB_PASS="" foreman start

You may additionally have to set up a database password and pass it as DB_PASS for the streaming tests to function.

Tests that send requests to Mastodon should be marked as needing VCR with the pytest.mark.vcr decorator. Streaming tests use a heavily monkeypatched version of VCR.py to work and may behave in weird ways sometimes.

import pytest

@pytest.mark.vcr()
def test_fun_new_feature(api):
    foo = api.fun_new_feature()
    assert foo = "bar"
