A cuelang testing package

testing

NOTE: Still in early beta and subject to breaking API changes

A assertion package, for cuelang.

Usage

Given github.com/ipcf/foo/foo.cue:

package foo

Bar: =~ "^([foo]|[bar])+$"

one might define tests as follows github.com/ipcf/foo/test/foo.cue:

package test

import "github.com/ipcf/testing"

import "github.com/ipcf/foo"

testing.T & {
	test: "foo.Bar": {
		[testing.NumDot]: subject: foo.Bar
		"0": assert: ok:     "foo"
		"1": assert: notOk:  "foobar" // will fail
		"2": assert: ok:     "bar"
		"3": assert: ok:     "barfoo"
		"4": assert: ok:     "barfoo"
		"5": assert: ok:     "barfoofoobarfoo"
		"6": assert: notOk:  ""
		"7": assert: notOk:  "bar1"
		"8": assert: notOk:  "1bar"
		"9": assert: notOk:  int
		"10": assert: notOk: null
		"11": assert: notOk: {}
	}
}

and then evaluate package in the test/ directory:

foo/test [master] » cue eval
test: {
    BarBaz: {
        "0": {
            subject: =~"^([foo]|[bar])+$"
            assert: {
                ok:   "foo"
                pass: true
            }
        }
        "1": {
            subject: =~"^([foo]|[bar])+$"
.
.
.

Kind of a lot of output so let's just look at failed tests:

foo/test [master] » cue eval --expression FAIL
BarBaz: {
    "1": {
        subject: =~"^([foo]|[bar])+$"
        assert: {
            pass:  false
            notOk: "foobar"
        }
    }
}

Looks like BarBaz: "1": notOk: "foobar" failed :+1
