1.32 +/**
1.33 + * Runs javadoc and then runs regression tests on the resulting output.
1.34 + * This class currently contains three tests:
1.35 + * <ul>
1.36 + * <li> String search: Reads each file, complete with newlines,
1.37 + * into a string. Lets you search for strings that contain
1.38 + * newlines. String matching is case-sensitive.
1.39 + * You can run javadoc multiple times with different arguments,
1.40 + * generating output into different destination directories, and
1.41 + * then perform a different array of tests on each one.
1.42 + * To do this, the run method accepts a test array for testing
1.43 + * that a string is found, and a negated test array for testing
1.44 + * that a string is not found.
1.45 + * <li> Run diffs: Iterate through the list of given file pairs
1.46 + * and diff the pairs.
1.47 + * <li> Check exit code: Check the exit code of Javadoc and
1.48 + * record whether the test passed or failed.
1.49 + * </ul>
