Test fails on Amazon and Codeship

Question

Building an application using Dropbox and Google Drive in Groovy, the tests run fine.

Code:

 def "It instantiates and configures the googleAuthorizationCodeFlowBuilder component"() {
         given:
         def ctx = grailsApplication.mainContext
         GoogleAuthorizationCodeFlow.Builder builder = ctx.googleAuthorizationCodeFlowBuilder

         expect:
 }

When running on Codeship and Amazon however, the test fails:

Message: Error creating bean with name 'googleAuthorizationCodeFlowBuilder': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow$Builder]: Constructor threw exception; nested exception is java.lang.NullPointerException

The googleAuthorizationflowBuilder bean only creates a GoogleAuthorizationCodeFlow.Builder (I use the Google java API).

EDIT 1: I reproduced the error on my machine by modifying doWithSpring:

def doWithSpring = {
        def config = application.config
        String googleSecret = getConfigValue(config, 'storage.google.secret')
        String googleAppId = null//getConfigValue(config, 'storage.google.appId')
        String appName = getConfigValue(config, 'storage.appName')

        if (!ConfigUtils.optional(config,'storage.google.disabled')) {
            googleNetHttpTransport(NetHttpTransport)
            googleJsonFactory(JacksonFactory)
            googleCredentialsBuilder(GoogleCredential.Builder) {
                transport = googleNetHttpTransport
                jsonFactory = googleJsonFactory
            }
       googleAuthorizationCodeFlowBuilder(GoogleAuthorizationCodeFlow.Builder, ref('googleNetHttpTransport'), ref('googleJsonFactory'),
                googleAppId, googleSecret, [DRIVE])
        }
    }

EDIT 2 : It seems that the error happen specifically when the AppId is null... The question is why is it null on the cloud and not on my machine...

Answer 1

Okay, it seems that the environment variables used to initialize the values of Config.groovy weren't set on the Codebase project, resulting in the aforementioned error.

The missing environment variables have been initialized on Codeship and everything works great now.
