The testing.assertEmpty()
function tests if an input stream is empty.
If not empty, the function returns an error.
Function type: Test
import "testing"
testing.assertEmpty()
The testing.assertEmpty()

Examples
Check if there is a difference between streams
This example uses the testing.diff()
function
which outputs the diff for the two streams.
The .testing.assertEmpty()
function checks to see if the diff is empty.
import "testing"
got = from(bucket: "example-bucket")
|> range(start: -15m)
want = from(bucket: "backup_example-bucket")
|> range(start: -15m)
got
|> testing.diff(want: want)
|> testing.assertEmpty()
