Different amount of Documents in ytbx.InputFile depending on how InputFile is created

[oscr]

Hi 👋

Depending on how an InputFile is created the amount of Documents differ for the same file/data. I would have expected no diff.

I ran the example program below with an empty file called example.txt in the same folder. I got the following output:

failed to compare input: comparing YAMLs with a different number of documents is currently not supported
expected len: 1
actual len: 0
expected file value: ''

package main

import (
	"fmt"
	"github.com/gonvenience/ytbx"
	"github.com/homeport/dyff/pkg/dyff"
	"os"
)

func main() {
	filename := "empty.txt"

	expectedFile, err := ytbx.LoadFile(filename)
	if err != nil {
		fmt.Errorf("failed to load expected: %v", err)
		os.Exit(1)
	}

	data, err := os.ReadFile(filename)
	docs, err := ytbx.LoadYAMLDocuments(data)
	if err != nil {
		fmt.Printf("failed to load actual: %v", err)
		os.Exit(1)
	}

	actualFile := ytbx.InputFile{
		Documents: docs,
	}

	_, err = dyff.CompareInputFiles(expectedFile, actualFile, dyff.KubernetesEntityDetection(true))
	if err != nil {
		fmt.Printf("failed to compare input: %v\n", err)
		fmt.Printf("expected len: %d\n", len(expectedFile.Documents))
		fmt.Printf("actual len: %d\n", len(actualFile.Documents))
		fmt.Printf("expected file value: '%s'\n", expectedFile.Documents[0].Value)
		os.Exit(1)
	}
}
