Collections

Example

const Collections = require('@cumulus/integration-test/Collections');

• Collections
  • createCollection(prefix, [overrides]) ⇒ Promise.<Object> ⏏
    • ~addCustomUrlPathToCollectionFiles(collection, customFilePath) ⇒ Array.<Object>
    • ~buildCollection(params) ⇒ Object
    • ~collectionExists(stackName, collection) ⇒ boolean
    • ~addCollection(stackName, collection) ⇒ Promise.<undefined>
    • ~addCollections(stackName, bucketName, dataDirectory, [postfix], [customFilePath], [duplicateHandling]) ⇒ Promise.<Array.<Object>>

createCollection(prefix, [overrides]) ⇒ Promise.<Object> ⏏

Create a randomized collection using the Cumulus API.

The default collection is very simple. It expects that, for any discovered file, the granule ID is everything in the filename before the extension. For example, a file named gran-1.txt would have a granuleId of gran-1. Filenames can only contain a single . character.

Collection defaults:

• name: random string starting with collection-name-
• version: random string starting with collection-version-
• reportToEms: false
• granuleId: '^[^.]+$'
• granuleIdExtraction: '^([^.]+)\..+$'
• sampleFileName: 'asdf.jpg'
• files:

  [
    {
      bucket: 'protected',
      regex: '^[^.]+\..+$',
      sampleFileName: 'asdf.jpg'
    }
  ]

Kind: Exported function
Returns: Promise.<Object> - the generated collection

createCollection~addCollections(stackName, bucketName, dataDirectory, [postfix], [customFilePath], [duplicateHandling]) ⇒ Promise.<Array.<Object>>

Add collections to database

Kind: inner method of createCollection
Returns: Promise.<Array.<Object>> - - collections that were added
