我正在使用TestNG
6.9.9来构建回归测试环境。但是遇到使用JUnit时从未遇到过的问题。在我看来,当每个测试用例完成时,如果测试方法在与调用方法相同的事务上下文中运行,则默认情况下将自动回滚每个数据的更改。但这似乎不是事实,而且我无法找出我的代码中是否有任何错误。请帮帮我。pom.xml中的属性,指示框架的版本
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<springframework.version>4.2.4.RELEASE</springframework.version>
<hibernate.version>4.3.11.Final</hibernate.version>
<testng.version>6.9.9</testng.version>
</properties>
显然,它们都是最新的。
我的测试课:
package com.noahwm.hkapp.api;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import org.testng.Assert;
import org.testng.annotations.Test;
import com.noahwm.hkapp.api.db.dao.AppUserDao;
import com.noahwm.hkapp.api.db.model.AppUser;
import com.noahwm.hkapp.api.service.AppUserService;
@ContextConfiguration(locations = { "classpath:applicationContext-test.xml" })
public class AppUserServiceTestNGTest extends AbstractTestNGSpringContextTests {
@Autowired
private AppUserService appUserService;
@Test
@Rollback
@Transactional
public void testApp() {
AppUser appUser = new AppUser();
appUser.setAge(10);
appUser.setGender("F");
appUser.setMobilePhone("13219201034");
appUser.setName("HKAPP Test");
appUserService.createUser(appUser);
String appUserId = appUser.getId();
Assert.assertNotNull(appUserId);
}
}
创建一个实体实例,然后调用createUser()将其保存到数据库。根据我在JUnit中所做的事情,即使我没有将@Rollback批注放在测试方法的前面,数据也会自动回滚。
AppUser的结构为:
package com.noahwm.hkapp.api.db.model;
import javax.persistence.Column;
import javax.persistence.Entity;
@Entity(name = "APP_USERS")
public class AppUser extends BaseDataModel {
@Column(name = "NAME")
private String name;
@Column(name = "GENDER")
private String gender;
@Column(name = "AGE")
private Integer age;
@Column(name = "MOBILE_PHONE")
private String mobilePhone;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getMobilePhone() {
return mobilePhone;
}
public void setMobilePhone(String mobilePhone) {
this.mobilePhone = mobilePhone;
}
}

package com.noahwm.hkapp.api.db.model;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;
import javax.persistence.Version;
import org.hibernate.annotations.GenericGenerator;
@MappedSuperclass
public class BaseDataModel {

如您所见,这是一个非常常见的Spring TestNG集成测试。但是无法使用自动回滚功能,这使我感到非常困惑。

在我的一般问题之后,我有一个使用Spring的特定问题,我想在下面每次执行DAO方法后回滚特定的测试方法。 添加和未能回滚插入 此外,在之前/之后获取连接并回滚也不会产生影响 我应该如何使用TestNG框架回滚单元测试?大多数答案使用JUnit的 我未能使用TestNG自动接线: 但是成功地使用了和include配置类includes jdbcTemplate/DataStource TestNG
问题内容: 有没有一种方法可以不使用ROLLBACK来回滚到事务的先前状态? 信息: ROLLBACK TRANSACTION请求没有相应的BEGIN TRANSACTION。 任何输入都会有很大的帮助。 谢谢 !!! 问题答案: 要在明确将IMPLICIT_TRANSACTIONS设置为ON时扩展gerrytans答案,可以使用ROLLBACK。请参阅与此相关的MSDN doco 。请注意,这不
我们有一个Spring事务回滚问题,其中回滚似乎不起作用 在用注释的服务层方法中,我调用三个不同的类来插入3条记录 中间插入从第四个表执行get以填充描述字段,但此get失败。我希望第一次插入会回滚,但它似乎没有发生 几点: 获取方法抛出运行时异常 我们使用和中定义的。Bean是在中创建的,它被导入到 在层 中没有 注释 我们已经使用了
这很好,但并不总是在代码中抛出运行时异常。因此,我挖掘并发现如下所示的rollbackFor; 现在,我必须更改所有代码,以使用RollBackfor更改@Transactional。但是还有其他方法可以将所有@transaction advice属性更改为rollbackFor=exception.class吗?
下面是一个使用JdbcTemplate的示例。我的问题是,由于runTimeException,doMultipleCalls()在第3步失败,一切是否都会回滚。我只有对多个调用的事务注释,而没有对其他调用的注释。所有人是否共享同一个事务会话?。如果没有,那么如何跨多个服务器传递相同的事务会话?
