How can you automate testing and deployment of AWS Lambda functions?
- Email notifications
- Manual deployment
- Using CI/CD pipelines
- Using physical servers
Implementing continuous integration and continuous deployment (CI/CD) pipelines allows you to automate testing and deployment processes for AWS Lambda functions, ensuring faster and more reliable releases.
What are some best practices for integration testing of AWS Lambda functions?
- Limiting testing to unit tests
- Manually testing each function
- Skipping testing altogether
- Using a staging environment
Using a staging environment similar to production can help mimic real-world scenarios and validate the integration of AWS Lambda functions with other services.
What is the purpose of unit testing in AWS Lambda function development?
- To deploy infrastructure as code
- To monitor production performance
- To test individual units or components of code
- To test the entire application end-to-end
Unit testing in AWS Lambda function development allows developers to test individual units or components of code in isolation, ensuring they work as expected before integration and deployment.
Which service can you use to simulate event triggers for testing AWS Lambda functions?
- AWS Lambda Console
- AWS SAM Local
- AWS Step Functions
- Amazon EventBridge
AWS SAM Local is a tool for local development and testing of serverless applications, including simulating event triggers for AWS Lambda functions.
How can you test AWS Lambda functions locally?
- Using AWS CloudFormation
- Using AWS CodeDeploy
- Using Amazon S3
- Using local development environments
Local development environments allow developers to test AWS Lambda functions on their own machines before deploying them to the cloud, ensuring functionality and identifying issues early in the development process.
In AWS Lambda, __________ can be used to precompile dependencies to improve cold start performance and reduce execution time.
- Containerization
- Layers
- Snapshots
- Triggers
In AWS Lambda, layers can be used to precompile dependencies to improve cold start performance and reduce execution time.
When dealing with complex dependencies, it's advisable to utilize __________ to manage version conflicts and ensure consistency.
- Continuous integration
- Dependency management tools
- Parallel computing
- Static analysis
Dependency management tools such as npm and pip can help manage version conflicts and ensure consistency when dealing with complex dependencies in AWS Lambda.
__________ is a technique used to package only necessary dependencies to minimize the size of deployment packages in AWS Lambda.
- Containerization
- Dependency management
- Dynamic linking
- Tree shaking
Tree shaking is a technique used to package only necessary dependencies to minimize the size of deployment packages in AWS Lambda.
AWS Lambda functions can include __________ dependencies that are required for their execution.
- build-time
- compile-time
- design-time
- runtime
Runtime dependencies are libraries or packages required for the execution of AWS Lambda functions, such as Python libraries or Node.js modules.
Scenario: You are testing an AWS Lambda function that processes data from Amazon S3. How would you simulate different S3 event triggers to ensure the function behaves correctly?
- Configure S3 event notifications
- Use AWS CloudWatch Events
- Use the AWS Management Console
- Utilize AWS SDKs
Using the AWS Management Console allows you to manually trigger AWS Lambda functions and simulate different S3 event triggers for testing purposes.
It's important to perform __________ testing to ensure AWS Lambda functions interact correctly with other AWS services.
- Acceptance
- Integration
- Regression
- Unit
Integration testing verifies that AWS Lambda functions interact correctly with other AWS services, ensuring seamless integration and functionality.
__________ testing assesses how AWS Lambda functions handle sudden spikes in traffic or increased workload.
- Functional
- Integration
- Load
- Stress
Load testing assesses how AWS Lambda functions handle sudden spikes in traffic or increased workload by subjecting them to varying levels of demand.
