WebDriver Lamda - Next Gen Scalable Test
- 1. WebDriver Lambda - Next Gen Scalable Test vodQA 2018 Bangalore Varuna Srivastava varunatester varunas@thoughtworks.com Vinayaka Mayura vinayakamayura vinaymgg@thoughtworks.com
- 2. Agenda ● Current Problem in Scaling tests ● Why/What AWS Lambda ● Lambda function ● AWS Lambda in UI testing ● Demo ● ROI ● Limitations ● References
- 3. What to expect from today’s session ● Basics of AWS Lambda ● How to create a Lambda function. ● Demo ● Stitching AWS Lambda to scale ui tests ● Advantages of AWS Lambda ● Limitations for AWS Lambda
- 4. What to not expect from today’s session ● Deep dive on serverless architecture ● Headless chrome ● Grid issues
- 5. Is Red a new Green ?
- 6. Are you still struggling with scaling tests?
- 7. “UI automated tests takes around 3 hrs to run 1000 tests which multiples by every check ins”
- 8. History
- 10. Serverless Architecture Serverless != No Servers
- 12. “AWS Lambda lets you run code without provisioning or managing servers…”
- 13. “There is no charge when your code is not running...”
- 16. What is Lambda Function ● Code ● Configuration ● Stateless ● Dependencies
- 17. How to invoke a lambda function ● Invoked via AWS console ● Invoked using AWS CLI ● Invoked via amazon API Gateway ● Invoked via event triggered using AWS Lambda
- 18. Ways to invoke a Lambda function ● RequestResponse Synchronous ● Events Asynchronous
- 19. Monitoring a lambda function... AWS XRay
- 20. Monitoring a lambda function AWS CloudWatch
- 22. Prerequisites ● Create a AWS Account ● Create a IAM user ● Associate a role for user
- 24. ROI ● Continuous Scalability: Achieving Massive Scale Not Massive Cost ● Improved Latency ● Lower Cost ● Pay only code runs
- 25. AWS Lambda Limitations ● Maximum execution duration per request ● Concurrent executions ● Aws Lambda cold starts ● Lambda is best for short processes.
- 26. See you in next vodQA with ● Rich reporting ● Multiple browser support ● Hands on execution on tests in lambda
- 28. Questions?
Editor's Notes
- Massive-scale automated testing only works well if it is never allowed to descend into a “sea of red”
- https://aws.amazon.com/solutions/case-studies/snapshot-blackboard-lambda/ Scalable selenoid
- Flexible Scaling High Availability No idle capacity No server management
- Let your service providers manage the scaling challenges. No need to fire alerts or write scripts to scale up and down. Handle quick bursts of traffic and weekend lulls the same way -- with peace of mind.
- Function-as-a-service compute and managed services charged based on usage rather than pre-provisioned capacity. You can have complete resource utilization without paying a cent for idle time. The results? 90% cost-savings over a cloud VM, and the satisfaction of knowing that you never pay for resources you don’t use.
- Deploy code without provisioning anything beforehand, or managing anything afterward. There is no concept of a fleet, an instance, or even an operating system. No more bothering the Ops department.
- Not supported languages
- Event Triggered -> Object Created in S3 Synchronous -> Request Response Asynchronous -> Event A service (e.g. S3) publishes an event to Lambda and invokes the function Pull - Lambda polls streaming event source (Kinesis, DynamoDB) and invokes the function when new data arrives
- Event Triggered -> Object Created in S3 Synchronous -> Request Response Asynchronous -> Event A service (e.g. S3) publishes an event to Lambda and invokes the function Pull - Lambda polls streaming event source (Kinesis, DynamoDB) and invokes the function when new data arrives
- Life of the lambda function is 5 mins
- Life of the lambda function is 5 mins
- How to execute
- Concurrency: able to scale up to 20,000 concurrent Lambda executions in testing One simulation of 20 million mortgages ran in 1.5 hours, more than 4X faster than existing process
- 5 mins Default 1000
