Java – files cannot be accessed from Src / main / resources through test cases

I have a file in Src / main / resources dat.

When I try to test a class that loads the file through a jar file, the test fails because it cannot find the file in the path (I / O exception) The path obtained through the test is:

/home/usr/workspace/project/target/test-classes/file. dat

But the files in the target / test class don't have any ideas?

Solution

Files from Src / main / resources will be available in the classpath when the main program runs, while files from Src / main / resources and Src / test / resources will be available in the classpath during the test run

One way to retrieve files located on the classpath is:

Object content = Thread.currentThread().getContextClassLoader().getResource("file.dat").getContent();

.. The content type depends on the file content You can also get the file as InputStream:

InputStream contentStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("file.dat");
