These are the classes in the test infrastructure and their methods. Each class described below is located in a module by the same name:
    from TestCmd import TestCmd
If a class is derived from another class, the superclass is given in parenthesis.

xxx At the moment, only limited documentation is present; basically, this is just something I can search when I need a particular function. In time, descriptions will be added for each method. There may be methods missing that need to be added and there may be internal routines present that need to be removed. TLC is needed until this becomes actual documentation. This is intended to be "quick-look" documentation and detailed documentation (including the vaunted examples) would be linked from the description.

TestCmd

Access to test directory. Create pathnames within the test directory. Write (and read) test files. Run a command and capture stdout and stderr. Miscellaneous operating system and file system operations. Succeed, fail, and skip test.

Initialize and tear down.

TestCmd.__init__(self, description = None, program = None, interpreter = None, workdir = None, subdir = None, verbose = None, match = None, combine = 0, universal_newlines = 1)
TestCmd.description_set(self, description)
TestCmd.program_set(self, program)
String or list of strings. The command to be tested and its arguments.
TestCmd.interpreter_set(self, interpreter)
String or list of strings. If the command to be tested is a script, the interpreter and any arguments.
TestCmd.workdir_set(self, path)

Creates a temporary working directory. if path is None or '' a unique name is created.

cnt = TestCmd.subdir(self, *subdirs)
Create subdirectories under the current working directory. Errors are ignored; the return value is the number of subdirectories actually created.
TestCmd.verbose_set(self, verbose)
TestCmd.preserve(self, *conditions)

If the test terminates due to one of the conditions, preserve the temporary test directory. The conditions can be any or all of 'pass_test', 'fail_test', or 'no_result'; no conditions preserves the directory for all cases.

TestCmd.cleanup(self, condition = None)

Skip, fail, succeed. One of these must be executed to terminate the test run.

TestCmd.no_result(self, condition = 1, function = None, skip = 0)

Reports NO RESULT from the test if the condition is true. If the test is failing, runs function with no arguments to clean up. The first skip stack frames are not displayed; set it to a large number to suppress the display completely.

TestCmd.fail_test(self, condition = 1, function = None, skip = 0)

Fails the test if the condition is true. If the test is failing, runs function with no arguments to clean up. The first skip stack frames are not displayed; set it to a large number to suppress the display completely.

TestCmd.pass_test(self, condition = 1, function = None)

Passes the test if the condition is true. If the test is succeeding, runs function with no arguments.

Workspace. The canonicalize() and workpath() methods appear to be equivalent; I don't know why both exist.

TestCmd.canonicalize(self, path)

Returns the full path within the working directory. The path argument may either be a string or a list of strings representing path elements.

TestCmd.workpath(self, *args)
Returns the full path within the working directory. The arguments are strings of path elements.
TestCmd.write(self, file, content, mode = 'wb')

Write content (a string) to the workspace file.

TestCmd.read(self, file, mode = 'rb')
Return the content of the workspace file.

Run command.

cmd_list = TestCmd.command_args(self, program = None, interpreter = None, arguments = None)

Constructs a command list. If program or interpreter are not specified, the corresponding default is used.

popen = TestCmd.start(self, program = None, interpreter = None, arguments = None, universal_newlines = None, **kw)
TestCmd.finish(self, popen, **kw)
TestCmd.run(self, program = None, interpreter = None, arguments = None, chdir = None, stdin = None, universal_newlines = None)

Test results.

content = TestCmd.stdout(self, run = None)

Return the standard output from the specified run. If run is None, the latest run is returned.

content = TestCmd.stderr(self, run = None)

Return the standard error from the specified run. If run is None, the latest run is returned.

bool = TestCmd.match(self, lines, matches)

Either match_exact or match_re depending on the match argument when the class was initialized.

bool = TestCmd.match_exact(self, lines, matches)

Returns true if lines and matches are the same and false otherwise. Both lines and matches can be either a string or a list of strings.

bool = TestCmd.match_re(self, lines, res)

Returns true if lines matches the regular expressions in res. Both lines and res can be either a string or a list of strings.

bool = TestCmd.match_re_dotall(self, lines, res)

Same as match_re except that the regular expressions are compiled with re.DOTALL.

module.diff_re(a, b, fromfile='', tofile='', fromfiledate='', tofiledate='', n=3, lineterm='\n')

A quick-and-dirty line-by-line diff. Both a and b must be lists of strings; lines in a are compared with regular expressions in b. The keyword arguments are all ignored.

Miscellaneous.

path = TestCmd.where_is(self, file, path=None, pathext=None)
path = TestCmd.tempdir(self, path=None)

Creates a temporary directory and arranges to remove it when the test completes. A path of None causes a unique directory to be created. Note that the path is not canonicalized.

TestCmd.chmod(self, path, mode)
TestCmd.symlink(self, target, link)
TestCmd.touch(self, path, mtime=None)
TestCmd.unlink(self, file)
TestCmd.sleep(self, seconds = default_sleep_seconds)
TestCmd.rmdir(self, dir)
TestCmd.readable(self, top, read=1)
TestCmd.writable(self, top, write=1)
TestCmd.executable(self, top, execute=1)

File status.

TestCommon.must_exist(self, *files)
Fail test if file(s) do not exist.

TestCommon.must_contain_all_lines(self, output, lines, title=None, find=None)

Ensure that all of the lines (a list of strings) appear in output. The title appears above any failure output. The find function returns true if the lie (second arg) is in the output (first arg).

TestCommon.must_contain_any_line(self, output, lines, title=None, find=None)

Ensure that output contains at least one of the lines specified. The `ti tle appears above any failure output.  The find` function returns true if the lie (second arg) is in the output (first arg).
