twisted.trial.reporter.Reporter : API documentation

_startTime =

The time when the first test was started. It defaults to None, which means that no test was actually launched. (type: float or NoneType)

_warningCache =

A set of tuples of warning message (file, line, text, category) which have already been written to the output stream during the currently executing test. This is used to avoid writing duplicates of the same warning to the output stream. (type: set)

_publisher =

The log publisher which will be observed for warning events. (type: LogPublisher (or another type sufficiently similar))

def __init__(self, stream=sys.stdout, tbformat='default', realtime=False, publisher=None): (source)

overrides twisted.trial.reporter.TestResult.__init__

overridden in twisted.trial.reporter.TreeReporter

Undocumented

def _observeWarnings(self, event): (source)

Observe warning events and write them to self._stream.

This method is a log observer which will be registered with self._publisher.addObserver.

Parameters event A dict from the logging system. If it has a 'warning' key, a logged warning will be extracted from it and possibly written to self.stream.

def stream(self): (source)

from twisted.trial.itrial.IReporter

Deprecated in Twisted 8.0. The io-stream that this reporter will write to

def separator(self): (source)

from twisted.trial.itrial.IReporter

Deprecated in Twisted 8.0. A value which will occasionally be passed to the write method.

def startTest(self, test): (source)

from twisted.trial.itrial.IReporter

overrides twisted.trial.reporter.TestResult.startTest

overridden in twisted.trial.reporter.TreeReporter, twisted.trial.reporter.VerboseTextReporter

Called when a test begins to run. Records the time when it was first called and resets the warning cache.

Parameters test ITestCase

def addFailure(self, test, fail): (source)

from twisted.trial.itrial.IReporter

overrides twisted.trial.reporter.TestResult.addFailure

overridden in twisted.trial.reporter.TextReporter, twisted.trial.reporter.TreeReporter, twisted.trial.reporter.VerboseTextReporter

Called when a test fails. If realtime is set, then it prints the error to the stream.

Parameters	test	`ITestCase` that failed.
	fail	`failure.Failure` containing the error.

def addError(self, test, error): (source)

from twisted.trial.itrial.IReporter

overrides twisted.trial.reporter.TestResult.addError

overridden in twisted.trial.reporter.TextReporter, twisted.trial.reporter.TreeReporter, twisted.trial.reporter.VerboseTextReporter

Called when a test raises an error. If realtime is set, then it prints the error to the stream.

Parameters	test	`ITestCase` that raised the error.
	error	`failure.Failure` containing the error.

def write(self, format, *args): (source)

from twisted.trial.itrial.IReporter

Deprecated in Twisted 8.0, use done instead.

Display a string to the user, without appending a new line.

def _write(self, format, *args): (source)

overridden in twisted.trial.reporter.TreeReporter

Safely write to the reporter's stream.

Parameters	format	A format string to write.
	*args	The arguments for the format string.

def writeln(self, format, *args): (source)

from twisted.trial.itrial.IReporter

Deprecated in Twisted 8.0, use done instead.

Display a string to the user, appending a new line.

def _writeln(self, format, *args): (source)

Safely write a line to the reporter's stream. Newline is appended to the format string.

Parameters	format	A format string to write.
	*args	The arguments for the format string.

def upDownError(self, method, error, warn, printStatus): (source)

from twisted.trial.itrial.IReporter

overrides twisted.trial.reporter.TestResult.upDownError

overridden in twisted.trial.reporter.TreeReporter

Deprecated in Twisted 8.0.

Called when an error occurs in a setUp* or tearDown* method

Parameters	warn	indicates whether or not the reporter should emit a warning about the error (type: Boolean)
	printStatus	indicates whether or not the reporter should print the name of the method and the status message appropriate for the type of error (type: Boolean)

def cleanupErrors(self, errs): (source)

from twisted.trial.itrial.IReporter

overrides twisted.trial.reporter.TestResult.cleanupErrors

overridden in twisted.trial.reporter.TreeReporter

Report an error that occurred during the cleanup between tests.

def _trimFrames(self, frames): (source)

Undocumented

def _formatFailureTraceback(self, fail): (source)

Undocumented

def _groupResults(self, results, formatter): (source)

Group tests together based on their results.

Parameters	results	An iterable of tuples of two or more elements. The first element of each tuple is a test case. The remaining elements describe the outcome of that test case.
	formatter	A callable which turns a test case result into a string. The elements after the first of the tuples in `results` will be passed as positional arguments to `formatter`.
Returns	A `list` of two-tuples. The first element of each tuple is a unique string describing one result from at least one of the test cases in `results`. The second element is a list of the test cases which had that result.

def _printResults(self, flavor, errors, formatter): (source)

Print a group of errors to the stream.

Parameters	flavor	A string indicating the kind of error (e.g. 'TODO').
	errors	A list of errors, often `failure.Failure`s, but sometimes 'todo' errors.
	formatter	A callable that knows how to format the errors.

def _printExpectedFailure(self, error, todo): (source)

Undocumented

def _printUnexpectedSuccess(self, todo): (source)

Undocumented

def printErrors(self): (source)

from twisted.trial.itrial.IReporter

Print all of the non-success results in full to the stream.

def _printErrors(self): (source)

overridden in twisted.trial.reporter.MinimalReporter

Print all of the non-success results to the stream in full.

def _getSummary(self): (source)

Return a formatted count of tests status results.

def printSummary(self): (source)

from twisted.trial.itrial.IReporter

Print a line summarising the test results to the stream.

def _printSummary(self): (source)

overridden in twisted.trial.reporter.MinimalReporter, twisted.trial.reporter.TreeReporter

Print a line summarising the test results to the stream.

def done(self): (source)

from twisted.trial.itrial.IReporter

overrides twisted.trial.reporter.TestResult.done

Summarize the result of the test run.

The summary includes a report of all of the errors, todos, skips and so forth that occurred during the run. It also includes the number of tests that were run and how long it took to run them (not including load time).
