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: branches_test.go
    path of file: ./repos/mergestat-lite/extensions/internal/github
    
    the code of the file until where you have to start completion: package github_test

import (
	"testing"

	"github.com/mergestat/mergestat-lite/extensions/internal/tools"
)

func TestBranches(t *testing.T) {
	cleanup := newRecorder(t)
	defer cleanup()

	db := Connect(t, Memory)

	rows, err := db.Query("SELECT * FROM github_repo_branches
    
func TestBranches(t *testing.T) {
	cleanup := newRecorder(t)
	defer cleanup()

	db := Connect(t, Memory)

	rows, err := db.Query("SELECT * FROM github_repo_branches('mergestat/mergestat') LIMIT 10")
	if err != nil {
		t.Fatalf("failed to execute query: %v", err.Error())
	}
	defer rows.Close()

	colCount, _, err := tools.RowContent(rows)
	if err != nil {
		t.Fatalf("failed to retrieve row contents: %v", err.Error())
	}

	if expected := 4; colCount != expected {
		t.Fatalf("expected %d columns, got: %d", expected, colCount)
	}

	rows, err = db.Query("SELECT * FROM github_repo_branches('askgitdev', 'askgit') LIMIT 10")
	if err != nil {
		t.Fatalf("failed to execute query: %v", err.Error())
	}
	defer rows.Close()

	colCount, _, err = tools.RowContent(rows)
	if err != nil {
		t.Fatalf("failed to retrieve row contents: %v", err.Error())
	}

	if expected := 4; colCount != expected {
		t.Fatalf("expected %d columns, got: %d", expected, colCount)
	}
