Codeception，Dbh，transactions

Question

我在Codeception中遇到了Dbh模块的一些问题。 首先，我想回滚每个测试中的每个数据库操作（在看到数据库之后）。所以我codeception.yml是

paths: 
    tests: tests 
    log: tests/_log 
    data: tests/_data 
    helpers: tests/_helpers 
settings: 
    bootstrap: _bootstrap.php 
    suite_class: \PHPUnit_Framework_TestSuite 
    memory_limit: 1024M 
    log: true 
    colors: true 
coverage: 
    enabled: true 
    remote: true 
    include: 
     - controllers/* 
     - models/* 
     - widgets/* 
modules: 
    enabled: [Db,Dbh] 
    config: 
     Db: 
      dsn: 'mysql:host=localhost;dbname=baxi' 
      user: 'root' 
      password: '' 
      #dump: tests/_data/dump.sql 
      cleanup: true 
     Dbh: 
      cleanup: false 

该指南说把这个引导

<?php 
\Codeception\Module\Dbh::$dbh = $dbh; 
?> 

但我怎样才能从DB模块$胸径之后？最后我得到错误

[Codeception\Exception\ModuleConfig]      
    Dbh module is not configured!        

    Transaction module requires PDO instance explicitly set. 
    You can use your bootstrap file to assign the dbh:   

    \Codeception\Module\Dbh::$dbh = $dbh 

如何正确设置？

Answer 1

也许你需要做这样的事情在你的引导文件：

$dbh = new PDO('mysql:host=localhost;dbname=baxi;charset=utf8', 'root', ''); 
\Codeception\Module\Dbh::$dbh = $dbh; 

Answer 2

您还可以使用配置PARAMS从codeception.yml：

\Codeception\Module\Dbh::$dbh = new PDO($settings['modules']['config']['Db']['dsn'], $settings['modules']['config']['Db']['user'], $settings['modules']['config']['Db']['password']);
