我需要在指定的目录中加载一些测试类来运行它们包含的junit测试
似乎我在方法Class.forName()和URLClassLoader。
我在路径为
的文件夹中有一些Junit测试类
C:\Documents\Java\Project\src\tests\net\sourceforge
和编译的类
C:\Documents\Java\Project\target\tests-classes\net\sourceforge
运行Class我需要JunitCore.run()的实例，但当我尝试使用Class.forName()方法时，我会得到NoClassDefFoundException或ClassNotFoundException。
我目前所做的是迭代target\tests-classes\中的所有文件并尝试加载这些类。
目录树结构类似于
SOURCEFILES
- Java
- Project
- src
- tests
- net
- sorceforge
- Test1.java
- Test2.java
- directory1
- Test3.java
- Test4.java
- directory2
- Test5.java
BINARIES
- Java
- Project
- target
- tests-classes
- net
- sorceforge
- Test1.class
- Test2.class
- directory1
- Test3.class
- Test4.class
- directory2
- Test5.class
以下是我的代码方法：
private void runJunitTest(JUnitCore junit, ArrayList<File> directories, String path) {
File f = new File(path); //path first call is usually "C:\Documents\Java\Project\src\tests\"
File bin = new File(txtClassTest.getText()); //bin path is "C:\Documents\Java\Project\target\tests-classes\"
File[] files = f.listFiles();
for (int i = 0; i < files.length; i++) {
if(files[i].isFile()){
String fullname = getFullyQualifiedName(files[i].getAbsolutePath(), txtTest.getText()); //getFullyQualifiedName return the fully qualified name of a class eg. net.sourceforge.Test1
try {
URLClassLoader urlClassloader = URLClassLoader.newInstance(new URL[] { bin.toURI().toURL() });
Class cl = Class.forName(fullname, false, urlClassloader);
Result result = junit.run(cl);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (MalformedURLException e1) {
e1.printStackTrace();
}
}
else{
directories.add(files[i]);
}
}
if(!directories.isEmpty()){
String dir = directories.get(0).getAbsolutePath();
directories.remove(0);
runJunitTest(junit, directories,dir);
}
}
}
我还尝试更改bin和path变量以潜入内部或走到路径的外部，但结果却大致相同。
编辑
拥有bin：...\target\test-classes\
