I’m going through Hartl’s Rails tutorial, which now uses Rails 4.2 and Guard with minitest.
Having Guard up and running does not automatically run tests; I have to press Enter to trigger the tests.
I can get the tests to run automatically upon starting Guard by changing “guard :minitest, spring: true, all_on_start: false do” in the Guardfile to “guard :minitest, spring: true do”. (This change means that the all_on_start parameter is set to true by default.)
How can I get the tests to run automatically when I modify files in the app? While I don’t need this automatic testing to get through railstutorial.org, I want to have this capability for working on more serious apps. I’d like the tests to begin BEFORE I click on the terminal window that I have dedicated to Guard testing.
