我试图弄清楚为什么我在尝试运行一些已经创建的测试并且确实运行了一段时间时出现错误的原因.这是Test类:
package com.chw.pxi.impl.oneway.formatter;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;
@RunWith(PowerMockRunner.class)
public class OnewayOldFormatterTestsWhy
{
@Before
public void setUp()
{
}
@Test
public void
test_nothing()
{
System.out.println("Yep");
}
}
当我尝试通过右键单击运行"test_nothing"方法时出现错误,选择"Run As/Junit test".
java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=test_nothing], {ExactMatcher:fDisplayName=test_nothing(com.chw.pxi.impl.oneway.formatter.OnewayOldFormatterTestsWhy)], {LeadingIdentifierMatcher:fClassName=com.chw.pxi.impl.oneway.formatter.OnewayOldFormatterTestsWhy,fLeadingIdentifier=test_nothing]] from org.junit.internal.requests.ClassRequest@3632be31

此项目的构建路径中有许多jar文件.我想我应该尝试创建一个新项目,看看问题是否存在.旁注 - 当我在另一个具有此测试的测试中对某个方法运行测试时 - 它运行良好而没有上述错误:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"dao-tests-context.xml"})
@TransactionConfiguration(transactionManager="transactionManager", defaultRollback=true)
//Note: This is a live database test but transactions will be rolled …我正在编写一些XML和一个XSD作为赋值...在我的XML中,我有一个名为a(非实际名称)的标签和名为的属性id.我的部分XML如下所示:
<a id="1">
...........
</a>
<a id="1">
............
</a>
当我使用XSD验证时,它不会给出错误....
<xsd:attribute name="id" type="xsd:string" />
我试图使用xsd:ID作为属性的数据类型,id但它给了我一个错误; 我无法弄清楚问题是什么.
我怎样才能做到这一点？
BigQuery是否具有MD5()功能？我知道它有cityhash但我特别需要MD5.谢谢!
我正在使用 java 8 流，并且无法在流的 foreach 内抛出异常。
stream.forEach(m -> {
try {
if (isInitial) {
isInitial = false;
String outputName = new SimpleDateFormat(Constants.HMDBConstants.HMDB_SDF_FILE_NAME).format(new Date());
if (location.endsWith(Constants.LOCATION_SEPARATOR)) {
savedPath = location + outputName;
} else {
savedPath = location + Constants.LOCATION_SEPARATOR + outputName;
}
File output = new File(savedPath);
FileWriter fileWriter = null;
fileWriter = new FileWriter(output);
writer = new SDFWriter(fileWriter);
}
writer.write(m);
} catch (IOException e) {
throw new ChemIDException(e.getMessage(),e);
}
});
这是我的异常类

我用DatePicker创建了一个简单的Expression Blend 4项目。我编辑了DatePicker的模板（包括其DatePickerTextBox），将水印文本从“选择日期”更改为“ dd / mm / yyyy”。Blend中生成的XAML将样式应用于原始DatePicker，并且此样式作为资源存储在Window.Resources中。但是，对水印文本所做的编辑不会生效。有任何想法吗？谢谢。（请注意，我不想求助于代码，我想了解如何使用Blend来实现。）这是窗口的XAML：

public class Transaction {
private final BigDecimal amount;
private final String accountType;

}
public class ResultantDTO {
private final List<Transaction> transactionsForAccount;
public ResultantDTO(List<Transaction> transactionsForAccount){

}
到目前为止,我使用以下代码对List<Transaction>by 进行分组accountType.
Map<String, List<Transaction>> transactionsGroupedByAccountType = transactions
.stream()
.collect(groupingBy(Transaction::getAccountType));
如何返回a List<ResultantDTO>,将List从每个map键传递到构造函数中,ResultantDTO每个包含一个accountType？
假设我有以下内容ConcurrentHashMap:
ConcurrentHashMap<Integer,String> indentificationDocuments = new ConcurrentHashMap<Integer,String>();
indentificationDocuments.put(1, "Passport");
indentificationDocuments.put(2, "Driver's Licence");
如何使用for循环迭代地图并将每个条目的值附加到字符串？
public interface ABC {
public boolean removeUser(String userId) throws OTPServiceException, RemoteException;
}
ABC abc= mock(ABC.class);
doNothing().when(abc).removeUser(anyString());
我试过这样的.我得到了以下异常.
org.mockito.exceptions.base.MockitoException:
Only void methods can doNothing()!
Example of correct use of doNothing():
doNothing().
doThrow(new RuntimeException())
.when(mock).someVoidMethod();
Above means:
someVoidMethod() does nothing the 1st time but throws an exception the 2nd time is called
只是想知道是否有人可以帮助我.我试图将一个数组返回到main方法并让它打印到我的屏幕.我是编码新手,刚开始.此代码编译但没有打印输出.我想我在主要部分缺少一行代码,但我无法弄明白.任何帮助将非常感激.
public class DivideArray {
public static void main(String[]args){
double myNumbers[] ={1.4,3.43,5.6,6.94,8.1,56.2};
double m = 2.2;
}
public static double[] scaleArray(double m, double myNumbers[]){
double array1[]= new double[myNumbers.length];
for(int i =0;i<myNumbers.length;i++){
array1[i]=myNumbers[i]/m;
}
for(int i =0;i<array1.length;i++){
System.out.println(array1[i]);
}
return array1;
}
}
