How to test ActionMailer in Rails Discussion

Great episode, Chris. I like how you said you don't really need to test CSS styling but instead focus on testing the higher level functionality of your mailers. That way, a developer doesn't go down a rabbit hole writing too fine grained tests.

Also, the last point about ActionMailer::Base.deliveries makes me wonder what the difference is between that and assert_emails.


Cool, thanks. I've been using mailcatcher, which is great for developing but you have to reload! in the console to get changes in the templates to show up. Previews looks much better.


Webpacker::Manifest::MissingEntryError in Pages#home i get this error when i run integration tests, can any one help?


coaching for the line courses is too heavy to learn and get a good score but you can concentrate on learning English descriptive linguistics or academic writing with and more behavior of writing you'll solely hump which is cheap and provides quality labor inside the amount of your time that you just require.


Hello all of you, today I want to tell you about DoMyEssay's ability to work effectively with a variety of subjects, as stated in the, prompted me to place an order for a comprehensive literature analysis. The essay I received was accurate, interesting and well-written, showing a deep understanding of the text and its context. NoCramming's review aptly assessed the experience, making the service a reliable resource for students looking for academic help.
