如何获取测试资源文件？

Question

在单元测试中,我需要导入一个csv文件.它位于资源文件夹中,即src/test/resources

Answer 1

如果您有可用的文件,例如在进行单元测试时,这可能非常有用 - 这不会从jar AFAIK中加载它.

URL url = Thread.currentThread().getContextClassLoader().getResource("mypackage/YourFile.csv");
File file = new File(url.getPath());
// where the file is in the classpath eg. <project>/src/test/resources/mypackage/YourFile.csv

Answer 2

您可以使用当前线程的类加载器访问测试资源:

InputStream stream = Thread.currentThread().getContextClassLoader()
    .getResourceAsStream("YOURFILE.CSV");

Answer 3

用番石榴

import com.google.common.io.Resources;
URL url = Resources.getResource("YourFile.csv");

Answer 4

// assuming a file src/test/resources/some-file.csv exists:

import java.io.InputStream;
// ...
InputStream is = getClass().getClassLoader().getResourceAsStream("some-file.csv");
