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: main_test.go
    path of file: ./repos/dendrite/cmd/create-account
    
    the code of the file until where you have to start completion: package main

import (
	"bytes"
	"io"
	"testing"
)

func Test_getPassword(t *testing.T) {
	type args struct {
		password string
		pwdFile  string
		pwdStdin bool
		reader   io.Reader
	}

	pass := "mySecretPass"
	passwordFile := "testdata/my.pass"
	reader := 
    
func Test_getPassword(t *testing.T) {
	type args struct {
		password string
		pwdFile  string
		pwdStdin bool
		reader   io.Reader
	}

	pass := "mySecretPass"
	passwordFile := "testdata/my.pass"
	reader := &bytes.Buffer{}
	_, err := reader.WriteString(pass)
	if err != nil {
		t.Errorf("unable to write to buffer: %+v", err)
	}
	tests := []struct {
		name    string
		args    args
		want    string
		wantErr bool
	}{
		{
			name: "password defined",
			args: args{
				password: pass,
			},
			want: pass,
		},
		{
			name: "pwdFile defined",
			args: args{
				pwdFile: passwordFile,
			},
			want: pass,
		},
		{
			name:    "pwdFile does not exist",
			args:    args{pwdFile: "iDontExist"},
			wantErr: true,
		},
		{
			name: "read pass from stdin defined",
			args: args{
				pwdStdin: true,
				reader:   reader,
			},
			want: pass,
		},
	}
	for _, tt := range tests {
		t.Run(tt.name, func(t *testing.T) {
			got, err := getPassword(tt.args.password, tt.args.pwdFile, tt.args.pwdStdin, tt.args.reader)
			if !tt.wantErr && err != nil {
				t.Errorf("expected no error, but got %v", err)
			}
			if got != tt.want {
				t.Errorf("getPassword() = '%v', want '%v'", got, tt.want)

	}
