How can the developer test a specific Lambda function locally?

  • A. Run the sam package and sam deploy commands. Create a Lambda test event from the AWS Management Console. Test the Lambda function.
  • B. Run the cdk synth and cdk deploy commands. Create a Lambda test event from the AWS Management Console. Test the Lambda function.
  • C. Run the cdk synth and sam local invoke commands with the function construct identifier and the path to the synthesized CloudFormation template.

The developer can test a specific Lambda function locally by running the cdk synth command to synthesize the AWS CDK application into an AWS CloudFormation template. Then, the developer can use the sam local invoke command with the function construct identifier and the path to the synthesized CloudFormation template to test the Lambda function locally (option C).

o test a specific Lambda function locally when using the AWS Cloud Development Kit (AWS CDK), the developer can use the AWS Serverless Application Model (AWS SAM) CLI's local testing capabilities in conjunction with the CDK. The typical process would be: Run cdk synth to synthesize the AWS CDK app into a CloudFormation template. Use sam local invoke to run the specific Lambda function locally, providing the function's logical identifier and the path to the synthesized CloudFormation template as arguments.
