|
|
|
|
This class tests the hacking checks in ceilometer.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.
