How do I access a text file for JUnit test in Android?

Question

How can I access a text file in my directory 'src/test/resources'

I can't seem to get it to pickup during my JUnit test

mobile/build.gradle:

sourceSets {
        test {
            java {
                srcDirs = [ 'src/test/java' ]
            }
            resources {
                srcDirs = [ 'src/test/resources' ]
            }
        }
    }

Test method:

@Test
public void test_file() {
    URL resource = getClass().getResource("file_four_lines.txt");
    File file = new File(resource.getFile()); // Get NullPointerException here
    ...

}

Answer 1

Prefix the file path with /.

Basically, you'd do something like this:

File helloBleprintJson = new File(
        getClass().getResource("/helloBlueprint.json").getPath());

Above snippet is taken from here.
