[英]Jmock Mockery, mocking a file system object
I want to be able to mock the File object in java using Mockery. 我希望能够使用Mockery模拟Java中的File对象。 I seems like we may not be able to create an interface for the File in java.
我似乎无法在Java中为File创建接口。 Is this possible?
这可能吗?
EDIT: 编辑:
I need to test the indexDoc function in Indexer Class. 我需要测试Indexer类中的indexDoc函数。
@Test
public void testindexDocs()
{
final File f = mockFile.mock(File.class);
File file = new File("test");
mockFile.setImposteriser(ClassImposteriser.INSTANCE);
final String[] files = {
"C:\\test\\",
"C:\\test\\test1.html",
"C:\\test\\test2",
"C:\\test\\test3.html"};
mockFile.checking(new Expectations(){
{
one(f).list();will(returnValue(files));
}
});
//TODO test if list() how many time i have called
//Document doc = HTMLDocument.Document(file); in function indexDocs
}
Index Docs function in Indexer class Indexer类中的Index Docs函数
private static void indexDocs(File file) throws Exception{
//Check for file to be a directory or file to be indexed look for html files and add to document
if(file.isDirectory()){
String[] files = file.list();
Arrays.sort(files);
for (int i = 0; i < files.length; i++) // recursively index them
indexDocs(new File(file, files[i]));
} else if(file.getPath().endsWith(".html") || file.getPath().endsWith("htm")){
// Get the document from HTMLDocument class which takes care of stripping of HTML tag, get the path
// of HTML file and title of HTML document.
Document doc = HTMLDocument.Document(file);
// TODO Get the book of HTML, it can be a part of HTML document class.
writer.addDocument(doc);
}
}
Don't mock the file system. 不要嘲笑文件系统。 We tried to do this in the early days and it diverted us from using tests to guide the design.
我们在早期尝试这样做,这使我们无法使用测试来指导设计。
From a quick look at your code, there are two things going on, one is file navigation, the other is html stripping. 快速查看您的代码,有两件事正在进行,一是文件导航,二是html剥离。 Perhaps one option would be to introduce a html stripping object (passed in as a collaborator) and mock that, then write tests against examples in a real file system.
也许一种选择是引入html剥离对象(作为协作者传入)并对其进行模拟,然后针对实际文件系统中的示例编写测试。
Jmock can mock concrete classes. Jmock可以模拟具体的类。 Just do
做就是了
Mockery context = new Mockery();
context.setImposteriser(ClassImposteriser.INSTANCE);
您遇到的问题是确切的原因,应该使用抽象而不是具体的类。
