You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: docs.go
    path of file: ./repos/benthos/internal/config/test
    
    the code of the file until where you have to start completion: package test

import (
	"bytes"
	"fmt"
	"text/template"

	"gopkg.in/yaml.v3"

	"github.com/benthosdev/benthos/v4/internal/docs"

	_ "embed"
)

const fieldTests = "tests"

//go:embed docs.md
var testDocs string

type testContext struct {
	Fields []docs.FieldSpecCtx
}

// DocsMarkdown returns a markdown document for the templates documentation.
func DocsMarkdown() ([]byte, error) {
	testDocsTemplate := docs.FieldsTemplate(false) + testDocs

	var buf bytes.Buffer
	err := template.Must(template.New("tests").Pars
    
func FromAny(v any) ([]Case, error) {
	if t, ok := v.(*yaml.Node); ok {
		var tmp struct {
			Tests []yaml.Node
		}
		if err := t.Decode(&tmp); err != nil {
			return nil, err
		}
		var cases []Case
		for i, v := range tmp.Tests {
			pConf, err := caseFields().ParsedConfigFromAny(&v)
			if err != nil {
				return nil, fmt.Errorf("%v: %w", i, err)
			}
			c, err := CaseFromParsed(pConf)
			if err != nil {
				return nil, fmt.Errorf("%v: %w", i, err)
			}
			cases = append(cases, c)
		}
		return cases, nil
	}

	pConf, err := ConfigSpec().ParsedConfigFromAny(v)
	if err != nil {
		return nil, err
	}
	return FromParsed(pConf)
}
