This package provides test of the root modules
silx.test.utils
#
Utilities for writing tests.
temp_dir()
provides a with context to create/delete a temporary directory.
- utilstest = <silx.utils.ExternalResources.ExternalResources object>#
This is the instance to be used. Singleton-like feature provided by module
- temp_dir()[source]#
with context providing a temporary directory.
>>> import os.path >>> with temp_dir() as tmp: ... print(os.path.isdir(tmp)) # Use tmp directory
- add_gaussian_noise(y, stdev=1.0, mean=0.0)[source]#
Add random gaussian noise to synthetic data.
- Parameters:
y (ndarray) – Array of synthetic data
mean (float) – Mean of the gaussian distribution of noise.
stdev (float) – Standard deviation of the gaussian distribution of noise.
- Returns:
Array of data with noise added
- add_poisson_noise(y)[source]#
Add random noise from a poisson distribution to synthetic data.
- Parameters:
y (ndarray) – Array of synthetic data
- Returns:
Array of data with noise added
- add_relative_noise(y, max_noise=5.0)[source]#
Add relative random noise to synthetic data. The maximum noise level is given in percents.
An array of noise in the interval [-max_noise, max_noise] (continuous uniform distribution) is generated, and applied to the data the following way:
\(yn = y * (1. + noise / 100.)\)
- Parameters:
y (ndarray) – Array of synthetic data
max_noise (float) – Maximum percentage of noise
- Returns:
Array of data with noise added

#
Helper class to write Qt widget unittests.
- qWaitForWindowExposedAndActivate(window, timeout=None)[source]#
Waits until the window is shown in the screen.
It also activates the window and raises it.
See QTest.qWaitForWindowExposed for details.
- class TestCaseQt(methodName='runTest')[source]#
Base class to write test for Qt stuff.
It creates a QApplication before running the tests. WARNING: The QApplication is shared by all tests, which might have side effects.
After each test, this class is checking for widgets remaining alive. To allow some widgets to remain alive at the end of a test, set the allowedLeakingWidgets attribute to the number of widgets that can remain alive at the end of the test. With PySide, this test is not run for now as it seems PySide is leaking widgets internally.
All keyboard and mouse event simulation methods call qWait(20) after simulating the event (as QTest does on Mac OSX). This was introduced to fix issues with continuous integration tests running with Xvfb on Linux.
- DEFAULT_TIMEOUT_WAIT = 100#
Default timeout for qWait
- TIMEOUT_WAIT = 0#
Extra timeout in millisecond to add to qSleep, qWait and qWaitForWindowExposed.
Intended purpose is for debugging, to add extra time to waits in order to allow to view the tested widgets.
- classmethod tearDownClass()[source]#
Hook method for deconstructing the class fixture after running all tests in the class.
- property qapp#
The QApplication currently running.
- Press = 0#
Key press action code
- Release = 1#
Key release action code
- Click = 2#
Key click action code
- property QTest#
The Qt QTest class from the used Qt binding.
- keyClick(widget, key, modifier=0, delay=-1)[source]#
Simulate clicking a key.
See QTest.keyClick for details.
- keyClicks(widget, sequence, modifier=0, delay=-1)[source]#
Simulate clicking a sequence of keys.
See QTest.keyClick for details.
- keyEvent(action, widget, key, modifier=0, delay=-1)[source]#
Sends a Qt key event.
See QTest.keyEvent for details.
- keyPress(widget, key, modifier=0, delay=-1)[source]#
Sends a Qt key press event.
See QTest.keyPress for details.
- keyRelease(widget, key, modifier=0, delay=-1)[source]#
Sends a Qt key release event.
See QTest.keyRelease for details.
- mouseClick(widget, button, modifier=None, pos=None, delay=-1)[source]#
Simulate clicking a mouse button.
See QTest.mouseClick for details.
- mouseDClick(widget, button, modifier=None, pos=None, delay=-1)[source]#
Simulate double clicking a mouse button.
See QTest.mouseDClick for details.
- mouseMove(widget, pos=None, delay=-1)[source]#
Simulate moving the mouse.
See QTest.mouseMove for details.
- mousePress(widget, button, modifier=None, pos=None, delay=-1)[source]#
Simulate pressing a mouse button.
See QTest.mousePress for details.
- mouseRelease(widget, button, modifier=None, pos=None, delay=-1)[source]#
Simulate releasing a mouse button.
See QTest.mouseRelease for details.
- qSleep(ms)[source]#
Sleep for ms milliseconds, blocking the execution of the test.
See QTest.qSleep for details.
- classmethod qWait(ms=None)[source]#
Waits for ms milliseconds, events will be processed.
See QTest.qWait for details.
- qWaitForWindowExposed(window, timeout=None)[source]#
Waits until the window is shown in the screen.
See QTest.qWaitForWindowExposed for details.
- classmethod qWaitForDestroy(ref)[source]#
Wait for Qt object destruction.
Use a weakref as parameter to avoid any strong references to the object.
It have to be used as following. Removing the reference to the object before calling the function looks to be expected, else
deleteLater()
will not work.ref = weakref.ref(self.obj) self.obj = None self.qWaitForDestroy(ref)
- Parameters:
ref (weakref) – A weakref to an object to avoid any reference
- Returns:
True if the object was destroyed
- Return type:
bool
- class SignalListener[source]#
Util to listen a Qt event and store parameters
- arguments(callIndex=None, argumentIndex=None)[source]#
Returns positional arguments optionally filtered by call count id or argument index.
- Parameters:
callIndex (int) – Index of the called data
argumentIndex (int) – Index of the positional argument.
- karguments(callIndex=None, argumentName=None)[source]#
Returns positional arguments optionally filtered by call count id or name of the keyword argument.
- Parameters:
callIndex (int) – Index of the called data
argumentName (int) – Name of the keyword argument.
- partial(*args, **kargs)[source]#
Returns a new partial object which when called will behave like this listener called with the positional arguments args and keyword arguments keywords. If more arguments are supplied to the call, they are appended to args. If additional keyword arguments are supplied, they extend and override keywords.
