Introduction

Bromide is a snapshot library for Go, designed to simplify managing snapshot tests.

With Bromide, you can easily capture test output and then review any differences against expected values.

Usage

Write

go get github.com/cobbinma/bromide

import github.com/cobbinma/bromide

func TestSomething(t *testing.T) {
    text := "world"
    something := testStruct{
      example: &text,
      again:   5,
    }
    
    bromide.Snapshot(t, something)
}
