The help text for the event type field is animated using a technique
unaffected by `Capybara.disable_animation`. Wait for the animation.
Resolves: #2356
Works around: #2661
As of Rails 5.1:
- Rails has built-in support for running tests within database
transactions, so Database Cleaner is no longer needed for this.
- Rails automatically shares the database connection across threads,
so transactional_capybara is no longer needed.
Changes:
- Enable `use_transactional_tests`.
- Remove transactional_capybara.
- Remove the Database Cleaner test wrapper.
This resolves:
- transactional_capybara mismanages the shared database connection,
causing the connection to falsely report as idle after the first
test. At 6 minutes (idle_timeout + reaping_frequency) into testing,
the connection is closed, causing e.g. `PG::ConnectionBad` errors.
The `find` was added to try to fix the flickering test: ac3337b
`find` and `fill_in` have the same `default_max_wait_time`, so didn't
change the problem.
The reason why this fails sometimes is that the Javascript for the
description (for the text editor) moves the 'Do you require something
special?' link a bit down. This causes that the link is not actually
clicked if capybara found it before it moved. Ensuring that the link is
searched after the description has been introduced solves the problem.
