Test Smell: Bloated Construction

The Search class requires you to pass an InputStream on a Search object through its constructor. Your test builds an InputStream in two places. The first construction requires three statements:

utj3-refactor-tests/06/src/test/java/util/SearchTest.java

var pageContent = "There are certain queer times and occasions "
    + "in this strange mixed affair we call life when a man takes "
    + "this whole universe for a vast practical joke, though "
    + "the wit thereof he but dimly discerns, and more than "
    + "suspects that the joke is at nobody's expense but his own.";
var bytes = pageContent.getBytes();
var stream = new ByteArrayInputStream(bytes);
