Examples

Load a raw stream of tables in a test case

The following test uses array.from() to create two streams of tables to compare in the test.

import "testing"
import "array"

got =
    array.from(
        rows: [
            {_time: 2021-01-01T00:00:00Z, _measurement: "m", _field: "t", _value: 1.2},
            {_time: 2021-01-01T01:00:00Z, _measurement: "m", _field: "t", _value: 0.8},
            {_time: 2021-01-01T02:00:00Z, _measurement: "m", _field: "t", _value: 3.2},
        ],
    )

want =
    array.from(
        rows: [
            {_time: 2021-01-01T00:00:00Z, _measurement: "m", _field: "t", _value: 1.2},
            {_time: 2021-01-01T01:00:00Z, _measurement: "m", _field: "t", _value: 0.8},
            {_time: 2021-01-01T02:00:00Z, _measurement: "m", _field: "t", _value: 3.1},
        ],
    )

testing.load(tables: got)
