func StartBenchmark ¶

func StartBenchmark(b *testing.B, benchFunc func(b *testing.B))

Instruments the given benchmark func

Example of usage:

func factorial(value int) int {
		if value == 1 {
			return 1
		}
		return value * factorial(value-1)
}

func BenchmarkFactorial(b *testing.B) {
		scopeagent.StartBenchmark(b, func(b *testing.B) {
			for i := 0; i < b.N; i++ {
				_ = factorial(25)
			}
		}
}

func BenchmarkFactorialWithSubBenchmarks(b *testing.B) {
		res := 0

		b.Run("25", func(b *testing.B) {
			scopeagent.StartBenchmark(b, func(b *testing.B) {
				for i := 0; i < b.N; i++ {
					res = factorial(25)
				}
			})
		})

		b.Run("50", func(b *testing.B) {
			scopeagent.StartBenchmark(b, func(b *testing.B) {
				for i := 0; i < b.N; i++ {
					res = factorial(50)
				}
			})
		})

		b.Run("75", func(b *testing.B) {
			scopeagent.StartBenchmark(b, func(b *testing.B) {
				for i := 0; i < b.N; i++ {
					res = factorial(75)
				}
			})
		})

		b.Run("100", func(b *testing.B) {
			scopeagent.StartBenchmark(b, func(b *testing.B) {
				for i := 0; i < b.N; i++ {
					res = factorial(100)
				}
			})
		})

		_ = res
}

func StartTest ¶

func StartTest(t *testing.T, opts ...scopetesting.Option) *scopetesting.Test

Instruments the given test, returning a `Test` object that can be used to extend the test trace
