bundle.testing.tools.assertions.instance_identity(instance, class_type)

Validates that an instance belongs to a specified class or a subclass thereof.

Asserts that the first argument is an instance and not a class, and that it is an instance of the specified class or its subclass.

Parameters:

• instance – The object to check.

• class_type – The class to which the instance should belong.

Raises:

AssertionError – If instance is a class or not an instance of class_type or its subclasses.

bundle.testing.tools.assertions.compare(ref: object, tmp: object) → None

Compares two objects for equality and generates a detailed string diff if they differ.

Converts each object to a string and uses difflib to compare these string representations. If differences are found, an AssertionError is raised with a detailed diff.

Parameters:

• ref – The reference object to compare.

• tmp – The temporary object to compare against the reference.

Raises:

AssertionError – If ref and tmp are not equal, with a detailed diff as the error message.
