# Integration package
The main goal is to have integration tests here.
### Performance test
Right now we have `performance_test.go` to measure number of processed TX per second.
In order to run it:
```
$ cd integration
$ go test -bench=. -benchmem
```
Result:
```
10000 402421 ns/op 177370 B/op 90 allocs/op
PASS
ok github.com/nspcc-dev/neo-go/integration 4.360s
```
Which means that in 4.360 seconds neo-go processes 10 000 transactions.
