Using HAML instead of ERB causes tests to fail

This seems very basic, but I'm using Rails 5 and I swapped all of my views to HAML instead of ERB. Now one of my tests is failing saying the following:

ActionController::UnknownFormat: ProductsController#index is missing  a template for this request format and variant.

request.formats: ["text/html"]
request.variant: []
    test/controllers/products_controller_test.rb:9:in `block in <class:ProductsControllerTest>'

Is there anywhere to change the default, or is there another issue I have to address? My routes are fine, and I can access the index page no problem.

I saw the same issue and the solution for us was caused by adding the haml gem into development group in the Gemfile, make sure the haml related gems are in no group

It means a missing template for the #index method in controller. Rails has a convention, it will search for this file in /views/ directory, the associated html.erb or haml file, following the name convention.

You need haml installed, add gem 'haml' to the Gemfile, next bundle install in your console.

Seems that you are missing the view file index.html.haml in app/views/products
