Question

我使用普通弹簧jdbc和dao就位的弹簧配置很简单。我为dao层添加了一个测试用例，它具有以下功能。 - 获取设置 - 测试记录和值的数量 - 使用新值更新设置 - 测试更新的值。

我无法使用更新来断言值，下面是我得到的错误。不确定是什么问题。

Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 1.386 sec <<< FAILURE!
updateTest(com.sims.service.SettingsServiceTests)  Time elapsed: 1.086 sec  <<< FAILURE!
org.junit.ComparisonFailure: expected:<[My Org]> but was:<[New Org1]>
at org.junit.Assert.assertEquals(Assert.java:115)
at org.junit.Assert.assertEquals(Assert.java:144)
at com.abc.service.SettingsServiceTests.updateTest(SettingsServiceTests.java:57)

任何人都可以让我知道配置中有什么问题。我已经添加了applicationContext.xml，Dao和dao的单元测试。

的applicationContext.xml

Answer 1

Spring将在您使用时回滚数据库更新：

defaultRollback=true

Answer 2

我正在回答，因为我无法发表评论。我建议你参考以下链接： - http://www.journaldev.com/2603/spring-transaction-management-example-with-jdbc

我觉得你得到某种异常，在调用数据库查询时放一个try catch块。尝试深入了解堆栈跟踪，您将找到解决方案。

Spring单元测试没有从数据库获取更新的值
