spec_helper file that throws uninitialized constant RSpec::Mocks::Mock (NameError)
when I add the three lines at the bottom:
# This file was generated by the `rails generate rspec:install` command. Conventionally, all
# specs live under a `spec` directory, which RSpec adds to the `$LOAD_PATH`.
# The generated `.rspec` file contains `--require spec_helper` which will cause this
# file to always be loaded, without a need to explicitly require it in any files.
#
# Given that it is always loaded, you are encouraged to keep this file as
# light-weight as possible. Requiring heavyweight dependencies from this file
# will add to the boot time of your test suite on EVERY test run, even for an
# individual file that may not need all of that loaded. Instead, make a
# separate helper file that requires this one and then use it only in the specs
# that actually need it.
#
# The `.rspec` file also contains a few flags that are not defaults but that
# users commonly want.
#
# See http://rubydoc.info/gems/rspec-core/RSpec/Core/Configuration
RSpec.configure do |config|
# The settings below are suggested to provide a good initial experience
# with RSpec, but feel free to customize to your heart's content.
# These two settings work together to allow you to limit a spec run
# to individual examples or groups you care about by tagging them with
# `:focus` metadata. When nothing is tagged with `:focus`, all examples
# get run.
config.filter_run :focus
config.run_all_when_everything_filtered = true
# Many RSpec users commonly either run the entire suite or an individual
# file, and it's useful to allow more verbose output when running an

# Seed global randomization in this process using the `--seed` CLI option.
# Setting this allows you to use `--seed` to deterministically reproduce
# test failures related to randomization by passing the same `--seed` value

RSpec::Mocks::Mock.module_eval do

end

The solution to your issue is probably that your mock needs to respond to id
or to_param
in order for Rails to convert it into a url, it's calling to_s
as a last resort and wouldn't give the result you want.
The reason why Mock
is undefined is that module was an internal api and has since been renamed, (to Double as your error shows), however we don't recommend monkey patching it like this.
@JonRowe is that was https://github.com/rspec/rspec-activemodel-mocks is supposed to do? I remember mock_model
being a thing a while back but I think we moved it out of core?
@xaviershay Yep, that library implements a bunch of "fake active record" functionality.
It seems from other issues posted that this was an intentional breaking change in 3.0.0, but from the issues listed I haven't been able to put together a concrete answer to how I should change my code so as not to have this problem. Some suggest putting this in spec_helper:
But I cannot get that code to run, and even if I could, would that not just reintroduce bugs with Double#to_str?
Here is my test:
And failing line of code is the first
format
