The testing.load() function loads tests data from a stream of tables.

import "testing"

testing.load()

Parameters

tables

Input data. Default is piped-forward data (<-).

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.diff(got: testing.load(tables: got), want: testing.load(tables: want))
