java - Junit 4.11 TemporaryFolder 构造函数与 java.io.File

Question

我正在尝试这样做。它在 eclipse 中工作正常，但在 maven 中给出错误。

示例代码

File baseFolder=new File("C:\BASE_FOLDER");
temporaryFolder = new TemporaryFolder(baseFolder);


//Error in maven
[ERROR] symbol  : constructor TemporaryFolder(java.io.File)
[ERROR] location: class org.junit.rules.TemporaryFolder

任何链接或提示都会有帮助。谢谢。

完全错误:

symbol  : constructor TemporaryFolder(java.io.File)
location: class org.junit.rules.TemporaryFolder

因为 TemporaryFolder 是 TestRule ，您可以将它与 @Rule 注释一起使用。来自 Javadoc :

public static class HasTempFolder {
    @Rule
    public TemporaryFolder folder = new TemporaryFolder();

    @Test
    public void testUsingTempFolder() throws IOException {
        File createdFile = folder.newFile("myfile.txt");
        File createdFolder = folder.newFolder("subfolder");
        // ...
    }
}

或者如果您想指定位置:

File baseFolder = new File("C:\BASE_FOLDER");
@Rule
public TemporaryFolder folder = new TemporaryFolder(baseFolder);
