Powerful Command-Line Applications in Go: TestParseContent & TestRun failed (pages 53 - 54)

Tests on compare 2 slice of byte fail because there is a difference in the formatting we get after the parseContent() and goldenFile functions. The difference lies in different tabulation.

To bring them to a common state I suggest using the package go get -u github.com/yosssi/gohtml

func formatHTML(data []byte) []byte {
	// Convert to string for manipulation
	content := string(data)

	formattedHTML := gohtml.Format(content)

	// Return the formatted html as []byte
	return []byte(formattedHTML)
}

This formatHTML function will take raw HTML in a []byte format, format it using gohtml, and return the formatted HTML as []byte. Here’s a quick breakdown of how it works:

Conversion to String: string(data) converts the byte slice to a string, as gohtml.Format requires a string input.

Formatting*: gohtml.Format(content) processes the HTML string, adding indentation and spacing for readability.

Returning as []byte: []byte(formattedHTML) converts the formatted string back to []byte.

if !bytes.Equal(formatHTML(expected), formatHTML(result)) {
    t.Logf("golden:\n%s\n", formatHTML(expected))
    t.Logf("result:\n%s\n", formatHTML(result))
    t.Error("Result content doesn't match golden file")
}

Hello @Siarhei! Oddly enough, I had that same issue this morning. My text editor (vim) was configured to not expand tabs, I was using tabs for indenting, and the tabstop as set at 2. I solved the issue by editing the main.go file and using spaces instead of tabs.
