JUnit STDIO

A JUnit extension to run tests with piping file inputs to STDIN and validation against STDOUT.

This can be useful for example when writing solutions as unit tests for coding challenges such as on HackerRank.

Example:

@RunWith(StdioSuite.class)
@StdioInputs({"000", "001"})
public class ToUpperTest {

    @Test
    public void testToUpper() throws Exception {
        BufferedReader stdin = new BufferedReader(new InputStreamReader(System.in));
        String line = "";
        while ((line = stdin.readLine()) != null){
            System.out.println(line.toUpperCase());
        }
    }
}

JUnit will run testToUpper() two times based on the @StdioInputs annotation. The test runner first reads in input000.txt, pipes it to STDIN of the test and then compares its STDOUT to output000.txt. Then, the same is done for input001.txt and output001.txt respectively. The files are read as resources from the CLASSPATH in the same package where the class under test is located.
