使用JSON输出执行集成测试时出错 [英] Error while executing Integration Test with JSON output
问题描述
以下是我在控制器中的操作.我正在尝试通过集成测试来测试此操作.这也需要我模拟会话对象.我已经开始进行集成测试,但是运气不好.
Below is my action in the controller. I am trying to test this action via an integration test. This would require me to mock the session objects as well. I have started with the integration test, but have no luck with it.
def listData= {
def playerId=session["playerId"]
tuneInstanceList = tuneService.calculateId(playerId)
def listResult = [total: tuneInstanceList.size(), items: tuneInstanceList]
render listResult as JSON;
}
下面是我的服务类中的CalculateId方法:
Below is the CalculateId method in my service class:
List<Tune> calculateId(String playerId) {
try{
//read the sql file
String playerSql = grailsApplication.mainContext.getResource('classpath:' + Constants.PLAYER_FILE).inputStream.text
def sql = new groovy.sql.Sql(dataSource)
def params = [playerId:playerId]
def tuneInstanceList = new ArrayList<Tune>()
def results = sql.rows(playerSql, params)
tuneInstanceList = results.each {
def tune = new Tune()
tune.setPlayerId it.player_id
tuneInstanceList.add tune
}
return tuneInstanceList
}catch (Exception ex) {
log.error ex.message, ex
throw ex
}
//finally {
//sql.close()
//}
}
下面是我编写的集成测试.这是不正确的,我不确定应该在这里放什么.输入吗?
Below is the Integration Test that I wrote. This isn’t correct and I am not sure what I should be putting up here. Inputs?
public void testQuery () {
def myController = new TuneController()
myController.request.contentType = "text/json"
myController.tuneService = tuneService
myController.listData()
String actualJSON = myController.response.contentAsString
assertNotNull(actualJSON)
}
运行测试时出现以下错误.
I get the below error when I run the test.
无法在空对象上获取属性"request"
Cannot get property 'request' on null object
java.lang.NullPointerException:无法在空对象上获取属性"request"
java.lang.NullPointerException: Cannot get property 'request' on null object
想法?
推荐答案
为此场景制定了测试用例.下面是代码.谢谢!
Worked out the Test Case for this scenario.Below is the code. Thanks!
public void testJSONQuery () {
def tuneController = new TuneController()
tuneController.request.contentType = "text/csv"
tuneController.tuneService = tuneService
tuneController.session["playerId"]='AF67H'
tuneController.listData()
String tuneJSON = tuneController.response.contentAsString
log.info ('Number of Records on execution of query is' + tuneJSON.substring(9,10))
//Checks if the record count is greater than zero
assertTrue (new Integer(tuneJSON.substring(9,10)).intValue() > 0)
}
