Question

Answer 1

In rails 5,

I used this way to run single test file(all the tests in one file)

rails test -n /TopicsControllerTest/ -v

Class name can be used to match to the desired file TopicsControllerTest

My class class TopicsControllerTest < ActionDispatch::IntegrationTest

Output :

If You want you can tweak the regex to match to single test method \TopicsControllerTest#test_Should_delete\

rails test -n /TopicsControllerTest#test_Should_delete/ -v
