The custom RSpec matchers they use raises the following deprecation
warning
```
Using `stub` from rspec-mocks' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` instead. Called from /home/runner/work/openfoodnetwork/openfoodnetwork/spec/support/matchers/delegate_matchers.rb:22:in `block (2 levels) in <top (required)>'.
```
It's not worth maintaining those matchers to test such
implementation-related thing. Whether or not any delegations work is
something that will be caught by integration tests or directly stubbing
the collaborator object's methods.
This stems from
https://github.com/openfoodfoundation/openfoodnetwork/pull/6902.
Increases the maximum number of digits (on the left side of the decimal place) that the column can hold, to allow larger values. This change is made in Spree 2.2 and is relevant in cases with either large order values, or certain currencies that have large values as standard. For example, 100 UK Pounds is roughly 4000 Thai Baht. 1 million pounds is unlikely to ever be needed as a value, but 1 million Baht is not so unlikely...
#update_column(s) skips callbacks (which is useful), but it doesn't change the updated_at field on the record by default (which we should be doing in these cases).
This change is made in Spree 2.2 here: b367c629ce
This method is named "update distribution charge". What this method actually does is delete all of the fee adjustments on an order and all it's line items, then recreate them all from scratch. We call this from lots of different places all the time, and it's incredibly expensive. It even gets called from inside of transactions being run inside callbacks. Renaming it hopefully will add a bit of clarity.
This needs to be a lot more granular!
This method name (#included) is reserved and used internally by ActiveRecord. After updating Ruby, this has changed from a silent warning to a fatal error.
We can now do things like:
```
included_tax = order.adjustments.tax.included.sum(:amount)
additional_tax = order.adjustments.tax.additional.sum(:amount)
```
This method returns the same thing as the Spree::Order#line_items_adjustments scope, but in a slightly less useful format (an array instead of a relation). The method's name is also totally inaccurate, as currently the only adjustments that appear on line items are tax adjustments for inclusive tax rates, which by definition have no effect on the price whatsoever...
