To build a k6
binary with this extension, first ensure you have the prerequisites:
- Go toolchain
- Git
Then:
- Clone
xk6
:
git clone https://github.com/k6io/xk6.git
cd xk6
- Build the binary:
CGO_ENABLED=1 go run ./cmd/xk6/main.go build master \
--with github.com/dgzlopes/xk6-interpret
import interpret from 'k6/x/interpret';
export default function() {
var result = interpret.run(
`package interpret
import "fmt"
// fibonacci is a function that returns
// a function that returns an int.
func fibonacci() func() int {
x, y := 0, 1
return func() int {
x, y = y, x + y
fmt.Println("Calculated:",x)
return x
}
}
func Run(s interface{}) interface{} {
f := fibonacci()
var results []int
var i int64
for i = 0; i < s.(int64); i++ {
results = append(results,f())
}
return results
}
`,
10
);
console.log(`Results: ${result}`)
}
Result output:
