Test lambda functions

In this section we will create tests to see if the functions are working properly.

To test the functions, download the following file to your computer and run the command: aws dynamodb batch-write-item --request-items file://documentData.json

  • documentData.json (3 ko)

    • LambdaConsole

    Test listing functions

    1. Open the list_documents function console
    2. Click Test tab
    • Enter tc_1 for event name
    • Enter the below json for Event JSON
    {
  "pathParameters": {
    "id": "abcd1234"
  }
}
    1. Click Save, then click Test

    LambdaConsole

    1. You will get all the information of the user’s files with the id abcd1234

    LambdaConsole

    Test creating function

    1. Open the upload_document function console
    2. Click Test tab
    • Enter tc_1 for event name
    • Enter the below json for Event JSON
    {
  "body":{
      "user_id": "abcd1234",
      "file": "aws_serverless.doc",
      "folder": "",
      "identityId": "123456cvbn",
      "modified": "13-03-2023",
      "size": "2MB",
      "type": "doc",
      "tag": "aws, serverless"
  }
}
    1. Click Save, then clickTest

    LambdaConsole

    1. You will get a return result of succeeded

    LambdaConsole

    1. Open Documents table to check if added successfully

    LambdaConsole

    Test deleting function

    1. Opent the delete_document function console
    2. Click Test tab
    • Enter tc_1 for event name
    • Enter the below json for Event JSON
    {
  "pathParameters": {
    "id": "abcd1234"
  },
  "queryStringParameters": {
    "file": "aws-exports.js"
  }
}
    1. Click Save, then clickTest

    LambdaConsole

    1. You will get a return result of succeeded

    LambdaConsole

    1. Open Documents table to check if deleted successfully

    You are done creating Lambda functions that interact with DynamoDB. In the next post we will authenticate to the archive with the Amplify library.
