testing.assertEquals() function

Warning! This page documents an earlier version of Flux, which is no longer actively developed. Flux v0.36 is the most recent stable version of Flux.

The testing.assertEquals() function tests whether two streams have identical data. If equal, the function outputs the tested data stream unchanged. If unequal, the function returns an error.

import "testing"

testing.assertEquals(
  name: "streamEquality",
  got: got,
  want: want
)

The testing.assertEquals() function can be used to perform in-line tests in a query.

Assert of separate streams
import "testing"

want = from(bucket: "backup-telegraf/autogen")
  |> range(start: -5m)

got = from(bucket: "telegraf/autogen")
  |> range(start: -5m)

testing.assertEquals(got: got, want: want)
Inline assertion
import "testing"

want = from(bucket: "backup-telegraf/autogen")
  |> range(start: -5m)

from(bucket: "telegraf/autogen")
