Rspec tests failing when using Rails.cache, but pass if I do a binding.pry

I'm having a weird issue where I'm testing a controller that has a procedure that uses caching. The test is failing, but if I do a binding.pry inside the method that does the caching, the test passes.

example of the method containing the caching and the binding.pry:

def method_example:  data = Rails.cache.fetch(cache_key) do    ProcedureService.new(params).generate  end  binding.pry  dataend

Example of the test:

  it "reverts record amount" do    expect(record.amount).to eq((original_amount + other_amount).to_d)  end

The caching is done via redis_store.

When done in the development environment, it works fine. What I don't understand is why it is failing but passing when adding a stopper? It seems it could be something about the time it takes to fetch the cache
