+Feature: @bugsnag/plugin-express autoDetectErrors=false
+
+Background:
+  Given I store the api key in the environment variable "BUGSNAG_API_KEY"
+  And I store the notify endpoint in the environment variable "BUGSNAG_NOTIFY_ENDPOINT"
+  And I store the sessions endpoint in the environment variable "BUGSNAG_SESSIONS_ENDPOINT"
+  And I start the service "express-disabled"
+  And I wait for the host "express-disabled" to open port "80"
+
+Scenario: a synchronous thrown error in a route
+  Then I open the URL "http://express-disabled/sync"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: an asynchronous thrown error in a route
+  Then I open the URL "http://express-disabled/sync"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: an error passed to next(err)
+  Then I open the URL "http://express-disabled/next"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: a synchronous promise rejection in a route
+  Then I open the URL "http://express-disabled/rejection-sync"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: an asynchronous promise rejection in a route
+  Then I open the URL "http://express-disabled/rejection-async"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: a string passed to next(err)
+  Then I open the URL "http://express-disabled/string-as-error"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: throwing non-Error error
+  Then I open the URL "http://express-disabled/throw-non-error"
+  And I wait for 5 seconds
+  And I should receive no errors
+
+Scenario: a handled error passed to req.bugsnag.notify()
+  Then I open the URL "http://express-disabled/handled"
+  And I wait to receive an error
+  Then the error is valid for the error reporting API version "4" for the "Bugsnag Node" notifier
+  And the event "unhandled" is false
+  And the event "severity" equals "warning"
+  And the exception "errorClass" equals "Error"
+  And the exception "message" equals "handled"
+  And the exception "type" equals "nodejs"
+  And the "file" of stack frame 0 equals "scenarios/app-disabled.js"
+  And the event "request.url" equals "http://express-disabled/handled"
+  And the event "request.httpMethod" equals "GET"
+  And the event "request.clientIp" is not null
+
+Scenario: adding body to request metadata
+  When I POST the data "data=in_request_body" to the URL "http://express-disabled/bodytest"
+  And I wait for 5 seconds
+  And I should receive no errors
