[英]How to Mock Spring JDBCTemplate execute method in Junit Test case
[英]JUnit test case issue with fetching db connection along with play framework, spring jdbctemplate?
我正在編寫JUnit測試用例 ,其中嘗試獲取DataSource的過程正在獲取以下錯誤消息。
堆棧跟蹤:
java.lang.NullPointerException
at play.api.db.DB$.getDataSource(DB.scala:141)
at play.api.db.DB.getDataSource(DB.scala)
at play.db.DB.getDataSource(DB.java:22)
at dao.BaseDao.getJdbcTemplate(BaseDao.java:13)
在這里,我正在使用spring jdbctemplate,play框架和JUnit。 請找到我正在使用的以下資源文件。
application.conf
db.default.jndiName=DefaultDS
db.default.driver=oracle.jdbc.driver.OracleDriver
db.default.url="jdbc:oracle:thin:@//xx.xx.xx.xx:1521/XE"
db.default.user=work
db.default.pass=work
......

似乎您缺少加載應用程序的上下文。 檢查play.test.Helpers包。
嘗試將您的實際測試代碼放入以下塊中:
running(fakeApplication(), new Runnable() {
@Override
public void run() {
...your test here...
}
});
