Measuring Performance with Benchmarks in Go

A reliable and comprehensive test suite for your applications isn’t a luxury anymore—it’s a requirement. This course is the third in a series of "Testing in Go" programs that teach you how to test your Go applications to make sure what you ship works the first time. It focuses specifically on how to write benchmark tests in Go that capture micro benchmarks of your code's performance.

• Learn how to write benchmark tests in Go to capture micro benchmarks of your code's performance
• Understand the ways to benchmark your code (and nothing else)
• Uncover the secret ways the Go compiler tries to defeat you when you're running benchmarks
• Discover the ways to get around the traps the Go compiler sets when you're running benchmarks
• Learn how to avoid benchmarking setup/teardown code
• Explore methods for running profiles on your benchmarks to see what's going on under the hood
