我为 Stash 编写了一个事件处理程序，以通过消息总线架构发送消息。这是我fedmsgEventListener班上的一个例子：
@EventListener
public void opened(PullRequestOpenedEvent event)
{
HashMap<String, Object> message = prExtracter(event);
String originProjectKey = ((HashMap<String, Object>)message.get("source")).get("project_key").toString();
String originRepo = ((HashMap<String, Object>)message.get("source")).get("repository").toString();
String topic = originProjectKey + "." + originRepo + ".pullrequest.opened";
sendMessage(topic, message);
}
它获取一个事件，从中提取信息，根据事件中的信息构造一个主题，并调用一个方法来发送消息。我需要为所有这些事件处理程序编写单元测试。
这是运行我试图实现的第一个测试的类：
import org.junit.Test;
import com.cray.stash.MyPluginComponent;
import com.cray.stash.MyPluginComponentImpl;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertTrue;
public class MyComponentUnitTest
{
@Test
public void testMyName()
{
MyPluginComponent component = new MyPluginComponentImpl(null);
assertTrue(component.openPullRequest().contains(".pullrequest.opened"));
}
}
然后这里是测试调用的类和方法：
import com.atlassian.sal.api.ApplicationProperties;
import com.atlassian.stash.event.pull.*;
import org.mockito.Mock;
import static org.mockito.Mockito.*; …我在为带有 While 循环的方法编写 JUnit 测试时遇到一些困难。我的方法如下所示：
private void deleteMethod(DeleteRequest dr){
// below statement am calling some service which returns me a object after querying it from Database.
SomeObject ob = db.getdata(dr);
while(ob != null) {
// this method deletes the Data from DB
db.deleteData(ob);
// again calling the same service operation as we did before while loop. I have a situation where my service only returns single record at a time. It is avoidable that I need to do a dirty …我有以下c#代码来调用存储过程testproc,但是当我运行这个应用程序时,它说它找不到存储过程testproc.
这是我调用存储过程的c#代码:
SqlConnection con = new SqlConnection();
con.ConnectionString = "data source='example.com';user id='sa';password='password';persist security info=False;initial catalog=Test;Connect Timeout=100; Min Pool Size=100; Max Pool Size=500";
con.Open();
DataSet ds = new DataSet();
SqlCommand com = new SqlCommand("testproc",con );
SqlDataAdapter sqlda = new SqlDataAdapter(com);
//sqlda.SelectCommand.CommandText = "SELECT Id,Name1,ZipCode,StreetName,StreetNumber,State1,Lat,Lng,Keyword, ( 6371 * ACOS( COS( (12.925432/57.2958) ) * COS( (Lat/57.2958) ) * COS( ( Lng/57.2958 ) - (77.5940171/57.2958) ) + SIN( 12.925432/57.2958 ) * SIN( Lat/57.2958 ) ) ) AS distance FROM Business_Details where( (StreetName …我有Element类的数据.我正在尝试将其值写入文件,但我遇到了麻烦:
< Some process to acquire values into the variable "fieldData" >
// Prepare file output
FileWriter fstream = new FileWriter("C:/output.txt");
BufferedWriter out = new BufferedWriter(fstream);
Element field = fieldData.getElement(i);
out.write(field); // DOESN'T WORK: The method write(int) in the type BufferedWriter is not applicable for the arguments (Element)
out.write(field.getValueAsString()); // DOESN'T WORK: Cannot convert SEQUENCE to String
关于我应该如何处理这个案子的任何建议？另外,对于我来说,看到(即打印到屏幕)可用的静态变量和与对象相关的方法的最佳方法是什么？谢谢.
更多代码片段以帮助调试:
private static final Name SECURITY_DATA = new Name("securityData");
private static final Name FIELD_DATA = new Name("fieldData");
Element securityDataArray = msg.getElement(SECURITY_DATA); // …我正在使用COCOS2D为iPhone开发游戏.

我正在对方法的性能进行调查,最后发现开销是由if else语句的"else"部分引起的.我编写了一个小程序来说明性能差异,即使代码的else部分永远不会被执行:
public class TestIfPerf
{
public static void main( String[] args )
{
boolean condition = true;
long time = 0L;
int value = 0;
// warm up test
for( int count=0; count<10000000; count++ )
{
if ( condition )
{
value = 1 + 2;
}
else
{
value = 1 + 3;
}
}
// benchmark if condition only
time = System.nanoTime();
for( int count=0; count<10000000; count++ )
{
if ( condition )

public class TwitterResponse
{

{
_exception = exception;
_response = response;
}
可能是我的错误？
我想从C#代码执行位于服务器上的SSIS包.
我试图让这个运行:
public void Execute()
{
string folderName = "MYFOLDER";
string projectName = "MYPROJECT";
string serverName = @"MYSERVER\REGION";
String connectionString = String.Format("Data Source={0};Initial Catalog=msdb;Integrated Security=SSPI;", serverName);
using(SqlConnection sqlConnection = new SqlConnection(connectionString)) {
IntegrationServices integrationServices = new IntegrationServices(sqlConnection);
Catalog catalog = integrationServices.Catalogs["SSISDB"];
CatalogFolder catalogFolder = catalog.Folders[folderName];
PackageInfo package = catalogFolder.Projects[projectName].Packages[PackageName];
PackageInfo.ExecutionValueParameterSet batchIdParameter = new PackageInfo.ExecutionValueParameterSet {
ObjectType = package.Parameters["BatchId"].ObjectType,
ParameterName = "BatchId",
ParameterValue = package.Parameters["BatchId"].DesignDefaultValue
};
PackageInfo.ExecutionValueParameterSet dateIdParameter = new PackageInfo.ExecutionValueParameterSet
{
ObjectType = package.Parameters["DateId"].ObjectType,
ParameterName = "DateId",
ParameterValue = package.Parameters["DateId"].DesignDefaultValue …我一直在使用SQL Server中的datetime列.现在大多数时候我必须将日期时间的时间部分重置为'00:00:00.000'.
我使用cast函数来实现相同的目的:
select cast(cast(getdate() as date)as datetime)
现在我的其他团队成员使用其他功能:
select cast(floor(cast(GETDATE() as float))as datetime)
要么
SELECT CONVERT(VARCHAR,GETDATE(),105)
我应该记住哪个函数要记住索引列是日期时间类型列.(因此我使用强制转换两次转换datetime - > date - > datetime).
