from tempest.hacking import checks
from tempest.tests import base
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.
