Question

Having

ByteArrayOutputStream b = ...;

//some code under test writes to b

 Reader result = (convert b to reader);

 IOUtils.contentEqualsIgnoreEOL(expected, result);

How to convert a ByteArrayOutputStream to a Reader?

Answer 1

You can try

ByteArrayOutputStream baos = 
Reader reader = new InputStreamReader(new ByteArrayInputStream(baos.toByteArray()));

a simpler solution would be to check the contents of the buffer.

assertEquals(expected, baos.toString().trim());
