Grails集成測試不會倒退

Question

我正在學習書籍「Grails In Action」中的grails，我試圖從示例中運行集成測試。在本書中，它表示每個集成測試功能都應該在每次測試結束時回滾操作。它不回滾每個事務（因爲當我完成數據庫是骯髒的）。我試圖找出原因並找到了一個名爲「事務性」的屬性。據稱你將這個屬性設置爲true，它會使測試用例成爲事務性的，但它似乎沒有改變行爲。我已經在下面列出了單元測試的代碼。

我正在使用grails 1.3.7並連接到MySql數據庫。測試成功運行，它不會回滾。我在這個集成測試中做了什麼錯誤，它跳過了回滾？

UserIntegrationTests.groovy：

package com.grailsinaction 

import framework.TestTools 

class UserIntegrationTests extends GroovyTestCase { 
    static transactional = true 

    protected void setUp() { 
     super.setUp() 
    } 

    protected void tearDown() { 
     super.tearDown() 
    } 

    void testCreateUser() { 
     TestTools.banner(log, "testCreateUser()") 

     def user = new User(userId:"joe", password:"secret") 
     assertNotNull user.save() 
     assertNotNull user.id 

     def foundUser = User.get(user.id) 
     assertEquals 'joe', foundUser.userId 
    } 

    void testSaveAndUpdate() { 
     TestTools.banner(log, "testSaveAndUpdate()") 

     def user = new User(userId:"joe2", password:"secret") 
     assertNotNull user.save() 

     def foundUser = User.get(user.id) 
     foundUser.password = 'sesame' 
     foundUser.save() 

     def editedUser = User.get(user.id) 
     assertEquals 'sesame', editedUser.password 
    } 

    void testSaveThenDelete() { 
     TestTools.banner(log, "testSaveThenDelete()") 

     def user = new User(userId: 'joe3', password: 'secret') 
     assertNotNull user.save() 

     def foundUser = User.get(user.id) 
     foundUser.delete() 
     assertFalse User.exists(foundUser.id) 
    } 

    void testValidation() { 
     TestTools.banner(log, "testValidation()") 

     def user = new User(userId: 'chuck-norris', password: 'tiny') 
     assertFalse user.validate() 
     assertTrue user.hasErrors() 

     def errors = user.errors 
     assertNotNull errors 

     errors.allErrors.each { 
      log.info("field: ${it.field}, code=${it.code}, rejected=${it.rejectedValue}") 
     } 
    } 
} 

User.groovy

package com.grailsinaction 

class User { 
    String userId 
    String password 
    Date dateCreated 
    Profile profile 

    static constraints = { 
     userId(size: 3..20, unique: true) 
     password(size: 6..8, validator: {password, user -> 
      return (password != user.userId) 
     }) 
     dateCreated() 
     profile(nullable: true) 
    } 

    static mapping = { 
     profile lazy: false 
    } 

    static hasMany = [posts : Post] 
}

Answer 1

默認情況下，測試（和服務）是事務性的，因此您通常只在false時指定靜態transactional屬性。如果你沒有指定方言，它可能是自動檢測MySQL，但是這些表是使用可能是MyISAM的默認引擎創建的。 MyISAM表不是事務性的。一定要在使用MySQL時指定InnoDB方言，例如

test { 
    dataSource { 
     dialect= org.hibernate.dialect.MySQLInnoDBDialect 
     driverClassName = 'com.mysql.jdbc.Driver' 
     username = '...' 
     password = '...' 
     url = '...' 
     dbCreate = 'update' 
    } 
} 

或者如果您在所有環境中都使用MySQL，則可以將其移動到頂層（例如，

dataSource { 
    pooled = true 
    dialect = org.hibernate.dialect.MySQLInnoDBDialect 
    driverClassName = 'com.mysql.jdbc.Driver' 
} 

Answer 2

我有同樣的問題。

• 在我的情況下，

環境：STS（IDE）中，MySQL（數據庫）

Grails的集成測試必須回滾你知道（默認）。

'grails集成測試'嘗試在每次測試結束時回滾。

如果你的數據庫不支持事務..？

我改變自動創建數據庫表來直接創建表，選項Type = InnoDB。所以我可以解決它。

create table something（...）Type = InnoDB;
