# All Plugin Dynamic Finders returning a Version are tested here.
# When adding one to the spec/fixtures/db/dynamic_finder.yml, a few files have
# to be edited/created
#
# - spec/fixtures/dynamic_finder/expected.yml with the expected result/s
# - Then, depending on the finder class used: spec/fixtures/dynamic_finder/plugin_version/
#
# Furthermore, the fixtures files _passive_all.html are also used by plugins/themes
# finders in spec/app/finders/plugins|themes to check the items existence from the homepage
#
# In case of a failure, it's recommended to use rspec -e "<Full Description>" while fixing.
# e.g: rspec -e "WPScan::Finders::PluginVersion::Cardealerpress::HeaderPattern#passive"
# The -e option can also be used to test all HeaderPattern, for example: rspec -e "::HeaderPattern"
