diffview

This library opens your favourite diff viewer directly from your tests.

why

I did a lot of testing recently where I had to compare complex structs and or strings.

I really like the GoLand diff viewer.

I absolutely hated to copy stuff from the console to two files in order to use the GoLand diff view. So here is diffview.

current caveats

It should not run from within CI. I guess a testing flag should do. I'll fix this soon/contributions welcome.

usage

package diffview

import "testing"

var (
	a = `foo
bar
baz
`
	b = `foo
baz
bar`
)

func TestGolandDiffView(t *testing.T) {
	NewGoland().DiffViewBytes("test", []byte(a), []byte(b))
}
