def development?
  !!(webmock_enabled? || repl? || test? || rails_development?)
end

.webmock_enabled? ⇒ Boolean

WebMock stores the reference to ‘Net::HTTP` with constant `OriginalNetHTTP`, and when WebMock enables, the adapter swaps `Net::HTTP` reference to its mock object, @webMockNetHTTP.

Hence, we can detect by

1. Checking if `Net::HTTP` is referring to mock object
=> ::Net::HTTP.equal?(::WebMock::HttpLibAdapters::NetHttpAdapter.instance_variable_get(:@webMockNetHTTP))

2. Checking if `Net::HTTP` is referring to the original one
=> ::Net::HTTP.equal?(::WebMock::HttpLibAdapters::NetHttpAdapter::OriginalNetHTTP)

Returns:

  • (Boolean)
