mongodb - 帆の wercker + mongo db

Question

werckerを使用しようとしていますが、テストで mongodb に接続できないことがわかりません。

私は帆+帆モンゴを使用しています.npmテスト...私は常にエラーが発生し、モンゴDBに接続できます.これは私のwercker.ymlです:

box: nodesource/trusty:0.12.7
services:
  - id: mongo:2.6
# Build definition
build:
  # The steps that will be executed on build
  steps:
    - script:
        name: set NODE_ENV
        code: export NODE_ENV=development
    # A step that executes `npm install` command
    - npm-install
    # A step that executes `npm test` command
    - npm-test
    # A custom script step, name value is used in the UI
    # and the code value contains the command that get executed
    - script:
        name: echo nodejs information
        code: |
          echo "node version $(node -v) running"
          echo "npm version $(npm -v) running"

これは私のエラーメッセージです:
