mongodb - MongoDB插件-如何使其在测试过程中不创建数据源？

Question

我正在使用Grails 2.3.8和MongoDB的项目中进行开发。在我的项目中，我包括MongoDB GORM plugin和hibernate来简化数据库连接的工作:

BuildConfig.groovy

// default config stuff here

grails.project.dependency.resolution = {
   ...

   plugins {
       ...
       compile ":mongodb:3.0.3"
       runtime ":hibernate:3.6.10.4"
    }
}

DataSource.groovy

environments {

    development {
        grails {
            mongo {
                host = "localhost"
                port = 27017
                databaseName = "myDB"
                // runs without --auth option needs no authentication
            }
        }
    }

    production {
        grails {
            mongo {
                databaseName = "myDB"
                username = "user"
                password = "*****"
                replicaSet = [
                        "master-host:port",
                        "slave1-host:port",
                        "slave2-host:port"
                ]
            }
        }
    }
}

如果我在本地计算机(开发)或预生产版本的服务器上运行我的应用程序，这将很好地工作。

我的问题是我为 Controller 创建了一个集成测试，其中模拟了服务，根本不需要建立数据库连接。当我像这样运行测试时:

grails test test-app --debug-fork --stacktrace --verbose -integration

环境已正确设置为“测试”，但出现此异常:

基于堆栈跟踪的这一部分:

nested exception is com.mongodb.MongoTimeoutException: Timed out while waiting for a server that matches AnyServerSelector{} after 10000 ms

在我看来，无论环境是“测试”，该插件都试图连接到mongo实例。这是有道理的，因为如果我在计算机上启动本地mongo，则测试将成功运行。

我花了一天半的时间在这个问题上进行搜索，但是常见的答复是“您的mongo实例未运行”。我意识到，但是对于测试，我实际上不需要它。

为了获得更多信息，此测试必须在没有任何mongo实例运行并且抛出与预期完全相同的异常的Jenkins服务器中运行。

对此表示任何帮助，我们深表感谢。

集成测试针对“完全成熟”的grails应用程序运行-如果在dev和prod中使用数据库，则需要一个测试。

此外，如果您确实在执行自动化测试部分，则需要一个用于其他测试的测试数据库，因此现在就创建一个。即使此测试未使用它，它也构成了您正在测试的“完整grails环境”的一部分。

在您的Jenkins作业中，您可以传递环境设置以指示测试环境将指定的配置文件用于数据源。我使用存储在test / conf / app-config.groovy中的特定于测试的app-config.groovy文件来执行此操作。该配置指向Jenkins服务器可以看到的一个长期的AWS RDS实例(该数据库不在Jenkins服务器上)。 Jenkins构建步骤主要调用:

grails test-app -Dapp.config.location = test / conf / app-config.groovy集成:

(我在工作中面临着同样的问题，只是为所有三个环境(开发，生产和测试)创建了MySQL数据库。由于我们运行的客户端是在H2，MSSQL，Oracle或MySQL之间进行选择，因此要做更多的事情。
