Reset a new session directly after its creation in
`ActionDispatch::IntegrationTest#open_session`. Reset the session to a clean
state before making it available to the client's test code.
Issue #22742 reports unexpected behavior of integration tests that run multiple
sessions. For example an `ActionDispatch::Flash` instance is shared across
multiple sessions, though a client code will rightfully assume that each new
session has its own flash hash.
The following test failed due to this behavior:
class Issue22742Test < ActionDispatch::IntegrationTest
test 'issue #22742' do
integration_session # initialize first session
a = open_session
b = open_session
refute_same(a.integration_session, b.integration_session)
end
end
Instead of creating a new `ActionDispatch::Integration::Session` instance,
the same instance is shared across all newly opened test sessions. This is
due to the way how new test sessions are created in
`ActionDispatch::IntegrationTest#open_session`. The already existing
`ActionDispatch::IntegrationTest` instance is duplicated with `Object#dup`,
