How can I benchmark my Go test packages?

How can I benchmark my Go test packages?

You can use the built-in testing package in Go to create benchmarks. Use the testing.B type to write benchmark functions.

Can you show me an example of a benchmark function?

Sure! Here's a simple example:

func BenchmarkMyFunction(b *testing.B) {
    for i := 0; i < b.N; i++ {
        MyFunction()
    }
}

How do I run the benchmarks?

You can run your benchmarks using the command go test -bench=. in your terminal. This will execute all benchmark functions.

What output should I expect from the benchmark?

The output will show the number of operations per second and the average time taken for each operation, helping you assess performance.
