无法访问测试资源

Question

我在 ..\src\test\resources 文件夹中有一个文件 testPristineCopy.xlsx。在我的单元测试中

InputStream testInputStream = this.getClass().getResourceAsStream("/testPristineCopy.xlsx");

当我尝试使用 JUnit 运行单元测试时，我收到此行的错误。堆栈跟踪如下：

知道问题是什么吗？当测试用例在 Jenkins 上运行时，我需要这些资源可供测试用例访问。

您可以使用相对路径访问 src/test/resources 文件夹下的任何资源文件。像这样。

InputStream testInputStream = new FileInputStream(new File("src/test/resources/testPristineCopy.xlsx"));
