regex - ruby selenium webdriver minitest::test .* not matching in assert_match -

i having trouble getting regular expression match following:

expected /.*ipcal\nipcc\nipcm\nipcontact\nipescalate\nipim\n.ippm\nipradar./ match "equens-prod-ipmon01\nequens-prod-ipmon02\nequens-test-ipmon01\nevryone-prod-ipmon01\nevryone-prod-ipmon02\nipcal\nipcc\nipcm\nipcontact\nipescalate\nipim\niplocksmithv2\nipmonui\nippm\nipradar\nipradar new request".

does .* not match 0 or more times in ruby or need modifier allow match new lines, thinking 's' modifier.

thanks!

thanks everyone's help.

i needed add 'm' modifier assert_match , regular expression started matching.

here final product:

assert_match(/(?i).*ipcal.*ipcc.*ipcm.*ipcontact.*ipescalate.*ipim.*ippm.*ipradar.*/m, subtabs.text)
