go-testparrot 🦜

go-testparrot records and replies expected test values, so you don't have to hardcode complex test values.

About

Are you tired of hard coding values in tests? Do you copy paste failed test values like as monkey?

What if there would be a record button to record test values and reply them later, just like a parrot!

Features

• Simple interface for record and reply values based on sequential or key value.
• Generation of recorded values in readable go code.

Quick start

Create a package with some tests:

package example

import (
	"testing"

	"github.com/xtruder/go-testparrot"
)

func doSomething() string {
    return "value"
}

func TestSomething(t* testing.T) {
    value := doSomething()

    // When running in recording mode return value will equal
    // passed value and file with recordings will be generated.
    // When running without recording, values from recording file
    // will be replied.
    expected := testparrot.RecordNext(t, value)

    if value != expected {
        t.Errorf("doSomething() = %v; want %v", value, expected)
    }
}

func TestMain(m *testing.M) {
	testparrot.Run(m)
}

You must provide TestMain method that will run testparrot.Run of if you need additional steps after/before running tests, you can also use testparrot.BeforeTests and testparrot.AfterTests helper methods.

Record values

To record values run tests with recording enabled:

go test <package> -testparrot.record

This will record values and save them into <package>_recording_test.go file in same directory as tests.

You can also use go:generate by placing comment like:

//go:generate go test ./ -testparrot.record

in package under test and running go generate <package>

Run tests

Run tests like you woul ussually run them, but with recording disabled:

go test <package>
