Codeception，Dbh，事务

Question

我有一些问题与Dbh模块在Codec农田。首先，我想在每次测试中回滚每个数据库操作（当然是在看到InDatabase之后）。所以我的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

在指南说把这个放进引导程序之后

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

但如何从Db模块中获得$dbh？最后我得到了一个错误

[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

您还可以使用codeception.yml中的配置参数：

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

Answer 2

也许您需要在引导文件中执行以下操作：

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