英文:
JUnit testing with different data XML files using @Theory
问题
我在使用多个数据文件时，对于在JUnit测试中使用@Theory遇到了困难。
我正试图将两个XML文件用作我的测试输入，因此我有以下代码：
public class XmlParserTest{@DataPointpublic static Document document;@DataPointpublic static Document nsDocument;@Beforepublic void before() throws Exception{InputStream is = getClass().getResourceAsStream("xmlTest.xml");DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();factory.setNamespaceAware(true);DocumentBuilder builder = factory.newDocumentBuilder();XmlParserTest.document = builder.parse(is);XmlParserTest.document.getDocumentElement().normalize();is.close();is = getClass().getResourceAsStream("xmlNSTest.xml");XmlParserTest.nsDocument = builder.parse(is);XmlParserTest.nsDocument.getDocumentElement().normalize();}@Theorypublic void testGetAttribute(Document doc) throws Exception{NodeList ln = doc.getElementsByTagNameNS("*", "Event");...}}
基本上，我希望使用我的两个加载的XML文件运行该测试。
但是我收到异常：java.lang.Exception: No runnable methods
我查看了参数化字段，并看过了@Theory与静态设置字段的简单示例，但我无法弄清楚如何加载和使用文件。
任何见解都将非常有帮助。

I am having difficulty finding a solution to using @Theory on a JUnit test when using multiple data files.
I am trying to use 2 XML files as input to my tests so I have the following:
public class XmlParserTest{@DataPointpublic static Document document;@DataPointpublic static Document nsDocument;@Beforepublic void before() throws Exception{InputStream is = getClass().getResourceAsStream("xmlTest.xml");DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();factory.setNamespaceAware(true);DocumentBuilder builder = factory.newDocumentBuilder();XmlParserTest.document = builder.parse(is);XmlParserTest.document.getDocumentElement().normalize();is.close();is = getClass().getResourceAsStream("xmlNSTest.xml");XmlParserTest.nsDocument = builder.parse(is);XmlParserTest.nsDocument.getDocumentElement().normalize();}@Theorypublic void testGetAttribute(Document doc) throws Exception{NodeList ln = doc.getElementsByTagNameNS("*", "Event");...}}
So basically I want to run that test with my two loaded XML files.
I get the Exception: java.lang.Exception: No runnable methods
I've looked at parameterized fields and have seen simple examples of @Theory with statically set fields but I can't really figure out how to load and use files.
Any insight would be great.

以下是您要翻译的内容：
理论测试需要一个特殊的运行器（请参阅文档）：
@RunWith(Theories.class)public class XmlParserTest {....}
否则，JUnit 将尝试将该类作为“普通”单元测试运行，因此它会寻找带有 @Test 注解的方法。显然，没有这样的方法，因此会出现异常。
英文:
Theories require a special runner (see documentation):
@RunWith(Theories.class)public class XmlParserTest {....}
Otherwise, JUnit tries to run the class as a "regular" unit test, so it looks for methods annotated with @Test. Obviously there are no methods like this, hence the exception.
