        This method is used by Robot Framework itself when it builds suites.
        External parsers and other tools that want to produce suites with
        names matching names created by Robot Framework can use this method as
        well. This method is also used if :attr:`name` is not set and someone
        accesses it.

        The algorithm is as follows:

        - If the source is ``None`` or empty, return an empty string.
        - Get the base name of the source. Read more below.
        - Remove possible prefix separated with ``__``.
        - Convert underscores to spaces.
        - If the name is all lower case, title case it.

        The base name of files is got by calling `Path.stem`__ that drops
        the file extension. It typically works fine, but gives wrong result
        if the extension has multiple parts like in ``tests.robot.zip``.
        That problem can be avoided by giving valid file extension or extensions
        as the optional ``extension`` argument.

        Examples::

            TestSuite.name_from_source(source)
            TestSuite.name_from_source(source, extension='.robot.zip')

id: str property

An automatically generated unique id.

longname: str property

Deprecated since Robot Framework 7.0. Use :attr:full_name instead.

name: str property writable

Suite name.

If name is not set, it is constructed from source. If source is not set, name is constructed from child suite names by concatenating them with &. If there are no child suites, name is an empty string.

setup: KW property writable

Suite setup.

This attribute is a Keyword object also when a suite has no setup but in that case its truth value is False. The preferred way to check does a suite have a setup is using :attr:has_setup.

test_count: int property

Total number of the tests in this suite and in its child suites.

adjust_source(relative_to=None, root=None)

Adjust suite source and child suite sources, recursively.

:param relative_to: Make suite source relative to the given path. Calls pathlib.Path.relative_to()__ internally. Raises ValueError if creating a relative path is not possible. :param root: Make given path a new root directory for the source. Raises ValueError if suite source is absolute.

name_from_source(source, extension=()) staticmethod

Create suite name based on the given source.

This method is used by Robot Framework itself when it builds suites. External parsers and other tools that want to produce suites with names matching names created by Robot Framework can use this method as well. This method is also used if :attr:name is not set and someone accesses it.

The algorithm is as follows:

• If the source is None or empty, return an empty string.
• Get the base name of the source. Read more below.
• Remove possible prefix separated with __.
• Convert underscores to spaces.
• If the name is all lower case, title case it.

The base name of files is got by calling Path.stem__ that drops the file extension. It typically works fine, but gives wrong result if the extension has multiple parts like in tests.robot.zip. That problem can be avoided by giving valid file extension or extensions as the optional extension argument.

Examples::

TestSuite.name_from_source(source)
TestSuite.name_from_source(source, extension='.robot.zip')
TestSuite.name_from_source(source, ('.robot', '.robot.zip'))
