Question 1

How does Goad compare to Apache JMeter for load testing?

Accepted Answer

Goad excels in distributed, cost-effective testing using AWS Lambda for global loads, while JMeter offers more features like scripting and plugins but requires managing your own infrastructure. Goad is better for simple high-concurrency tests from multiple regions, whereas JMeter suits complex, customizable scenarios.

Question 2

How to set up AWS credentials for Goad?

Accepted Answer

Goad reads credentials from ~/.aws/credentials or the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables. You need an AWS account with permissions to create Lambda functions, IAM roles, and SQS queues, as detailed in the usage section.

Question 3

Can Goad test APIs with POST requests and custom headers?

Accepted Answer

Yes, Goad supports various HTTP methods including POST via the -m flag, allows setting custom headers with -H or in the INI file, and can include a request body, making it suitable for API testing beyond simple GET requests.

Question 4

What are the AWS costs for using Goad?

Accepted Answer

Goad itself is free and open-source, but you incur AWS charges for Lambda executions, SQS usage, and other resources. Costs are minimal for short tests (fractions of a penny as claimed), but can accumulate with frequent or high-concurrency runs.

Question 5

Does Goad support HTTPS and Docker deployment?

Accepted Answer

Yes, Goad supports HTTPS URLs and can be run as a Docker container that exposes a web API via WebSockets, allowing flexible deployment options as described in the Docker section of the README.

Question 6

How does Goad handle high concurrency up to 100,000 requests?

Accepted Answer

It distributes requests across multiple AWS Lambda instances in different regions, each running Go processes with concurrent goroutines, leveraging serverless scalability to achieve high throughput without managing servers.
