我无法在 grails 中运行单元测试。我有一个TransactionController（也可以在github 上获得）transactionAnalytics，我想测试如下方法，

TransactionController.groovy

package eccount


import org.codehaus.groovy.grails.web.json.JSONObject
import org.springframework.dao.DataIntegrityViolationException
import grails.converters.JSON

class TransactionController {
   def transactionService

   def transactionAnalytics = {
       searchRequest = searchRequest ?: new SearchRequest(requestParams: new HashMap<String, String>())
       configureRequestParams()
       def responseBytes = transactionService.getSearchResponse(searchRequest)
       def jsonResponse
       if (responseBytes)
            jsonResponse = JSON.parse(responseBytes)
       else
           jsonResponse = new JSONObject()
       render jsonResponse as JSON
   }
 }

TransactionController#transactionAnalytics（也可在 github 上获得）的相应测试如下，

TransactionControllerTests.groovy

package eccount



import org.junit.*
import grails.test.mixin.*

@TestFor(TransactionController)
class TransactionControllerTests {
    def INDEX_NAME = "gccount"

    void testTransactionAnalytics(){
        Map<String, String> params = new HashMap<String, String>()
        params.put("indexName",INDEX_NAME)
        //println params.get("indexName")
        //controller.params  = params
        controller.params.indexName  = "gccount"
        controller.transactionAnalytics()
        def jsonResponse = controller.response.json
        println jsonResponse
    }
}

当我运行控制器的方法时，出现以下异常

同样，在 没有留下任何报告file:///backup/gccount/target/test-reports。 无论如何，谁在这里实际上是空的？

尝试：

grails test-app TransactionController.testTransactionAnalytics

您忘记了方法名称前面的“测试”...是的...看来，您不必将其写在类名中，但必须在方法名中...

Grails Goodness: Invoking a Single Test Method似乎发布了错误的信息，因为以下代码不起作用。

$ grails test-app TransactionController.transactionAnalytics

正确的是初始化transactionService

$ grails test-app TransactionControllerTests.testTransactionAnalytics

或者

$ grails test-app TransactionController.testTransactionAnalytics
