This library opens your favourite diff viewer directly from your tests.
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.
It should not run from within CI. I guess a testing flag should do. I'll fix this soon/contributions welcome.
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))
}Feel free to add Openers for different operating systems/diff view tools.
