Testing Utilities

Summary

This page will provide developers with details of testing utilities, such as helper files, which are useful in creating unit tests.

Helper Functions

C++

The following helper files have been found in the Mantid/Framework/TestHelpers package:

• BinaryOperationMDTestHelper

• ComponentCreationHelper ComponentCreationHelper This creates instrument components that can then be used in a unit test.

• ICatTestHelper

• MDEventsTestHelper

• SANSInstrumentCreationHelper

• ScopedFileHelper This creates a file that is automatically deleted when no longer needed.

• WorkspaceCreationHelper This creates simple workspaces that can be used in a unit test. One of these workspaces has a full instrument.

Python

There are some testhelpers which are only available in Python, they can be found in the testhelpers-package.

• make_decorator - A function that returns a decorator for an algorithm without executing it.

• TemporaryFileHelper - A class that creates named temporary files and deletes them automatically when the object is deleted. Basically a thin wrapper around NamedTemporaryFile from the tempfile package.
