Question

I am comparing text files in junit using:

public static void assertReaders(BufferedReader expected,           BufferedReader actual) throws IOException {     String line;     while ((line = expected.readLine()) != null) {         assertEquals(line, actual.readLine());     }      assertNull('Actual had more lines then the expected.', actual.readLine());     assertNull('Expected had more lines then the actual.', expected.readLine()); } 

Is this a good way to compare text files? What is preferred?

Answer 1

junit-addons has nice support for it: FileAssert

It gives you exceptions like:

junitx.framework.ComparisonFailure: aa Line [3] expected: [b] but was:[a]
