 class HackingTestCase(base.TestCase):
+    """
+    This class tests the hacking checks in tempest.hacking.checks by passing
+    strings to the check methods like the pep8/flake8 parser would. The parser
+    loops over each line in the file and then passes the parameters to the
+    check method. The parameter names in the check method dictate what type of
+    object is passed to the check method. The parameter types are::
+
+        logical_line: A processed line with the following modifications:
+            - Multi-line statements converted to a single line.
+            - Stripped left and right.
+            - Contents of strings replaced with "xxx" of same length.
+            - Comments removed.
+        physical_line: Raw line of text from the input file.
+        lines: a list of the raw lines from the input file
+        tokens: the tokens that contribute to this logical line
+        line_number: line number in the input file
+        total_lines: number of lines in the input file
+        blank_lines: blank lines before this one
+        indent_char: indentation character in this file (" " or "\t")
+        indent_level: indentation (with tabs expanded to multiples of 8)
+        previous_indent_level: indentation on previous line
+        previous_logical: previous logical line
+        filename: Path of the file being run through pep8
+
+    When running a test on a check method the return will be False/None if
+    there is no violation in the sample input. If there is an error a tuple is
+    returned with a position in the line, and a message. So to check the result
+    just assertTrue if the check is expected to fail and assertFalse if it
+    should pass.
