如何编写Laravel4上单选按钮的代码感知功能测试

在具有codeception的Laravel 4上编写功能测试。

我的tests/functional/UserSignUpCept.php文件。

<?php 
$I = new FunctionalTester($scenario);
$I->am('a guest');
$I->wantTo('sign up for a musician account');
$I->amOnPage('/');
$I->click('Sign Up as User');
$I->seeCurrentUrlEquals('/user/register');
$I->fillField(['name' => 'email'], 'jon@mail.com');
$I->fillField(['name' => 'password'], '123456');
$I->fillField(['name' => 'password_confirmation'], '123456');
$I->fillField(['name' => 'first_name'], 'jon');
$I->fillField(['name' => 'last_name'], 'deo');
$I->selectOption(['form select[name=gender]'], 'm');
$I->selectOption(['name' => 'zipcode_id'], '1');
$I->fillField(['name' => 'phone'], '01234567891');
$I->click('Register');
$I->seeCurrentUrlEquals('');
$I->see('The user has been successfully created. Activation mail has been sent to your email address.');

我的注册视图

{{ Form::open(array('route' => 'user.register', 'class' => 'form-horizontal', 'role' => 'form')) }}
    <div class="col-xs-12 col-sm-12 col-md-6 col-lg-6">

                {{ Form::email('email', null, array('id' => 'email', 'class' => 'form-control', 'placeholder' => 'example@example.com', 'tabindex' => 1)) }}

我在终端上运行codeception

vagrant@homestead:~/Code/musician$ vendor/bin/codecept run functional
Codeception PHP Testing Framework v2.0.11
Powered by PHPUnit 4.4.5 by Sebastian Bergmann.
Functional Tests (1) -------------------------------------------------------------------------------------------------

There was 1 failure:
---------

Couldn't select option "form select[name=gender]"],"m":

Scenario Steps:
10. I select option "form select[name=gender]"],"m"
9 . I fill field {"name":"last_name"},"deo"
8 . I fill field {"name":"first_name"},"jon"
7 . I fill field {"name":"password_confirmation"},"123456"
6 . I fill field {"name":"password"},"123456"
5 . I fill field {"name":"email"},"jon@mail.com"

FAILURES!

我检查过http://codeception.com/docs/modules/Laravel4.但我解决不了。如何修复单选按钮组的此测试？

提前谢谢。
