Yii2 调用未定义的函数测试\codeception\unit\models\expect（）

我试图在Yi2基本应用程序中使用默认的ContactFormTest执行单元测试。但它给了我以下错误

E:\xampp\htdocs\news\tests>codecept run unit codeception\unit\models\ContactForm
Test.php

in E:\xampp\htdocs\news\tests\codeception\unit\models\ContactFormTest.php:46

和unit.suite.yml

"require-dev": {
    ...
    "codeception/specify": "*",
    "codeception/verify": "*"
}

如何解决此问题？

您的IDE是否识别

指定中的
expect
函数调用

如果没有，请尝试按照手册中的规定，将和添加到
要求开发人员
编写器依赖项：

然后运行
composer update
