JUnit for BufferedReader

[Shaheena_Sheikh]

new BufferedReader(new InputStreamReader(<inputStremObject>, StandardCharsets.UTF_8))

I have mocked InputStream, InputStreamReader and BufferedReader and I'm fetching a JSON file asset. <bufferedReaderObject>.readLine() throws IOException (error msg: Underlying input stream returned zero bytes) in my test file. How do I handle this JUnit scenario?
