symforce.test_util.test_case_mixin module

class SymforceTestCaseMixin(methodName='runTest')

Bases: TestCase

Mixin for SymForce tests, adds useful helpers for code generation

Parameters:

methodName (str) –

LieGroupOpsType

alias of Union[LieGroup, float]

KEEP_PATHS = ['.*/__pycache__/.*', '.*\\.pyc']

static should_update()

Return type:

bool

__init__(methodName='runTest')

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

Parameters:

methodName (str) –

static main(*args, **kwargs)

Call this to run all tests in scope.

Parameters:

• args (Any) –

• kwargs (Any) –

Return type:

None

static assertStorageNear(actual, desired, *, places=7, msg='', verbose=True)

Check that two elements are close. Handles sequences, scalars, and geometry types using StorageOps.

Parameters:

• actual (Any) –

• desired (Any) –

• places (int) –

• msg (str) –

• verbose (bool) –

Return type:

None

static assertLieGroupNear(actual, desired, *, places=7, msg='', verbose=True)

Check that two LieGroup elements are close.

Parameters:

• actual (Union[LieGroup, float]) –

• desired (Union[LieGroup, float]) –

• places (int) –

• msg (str) –

• verbose (bool) –

Return type:

None

static assertArrayEqual(actual, desired, msg='')

Called by unittest base class when comparing ndarrays when “assertEqual” is called. By default, “assertEqual” uses the “==” operator, which is not implemented for ndarrays.

Parameters:

• actual (ndarray) –

• desired (ndarray) –

• msg (str) –

Return type:

None

assertNotEqual(first, second, msg='')

Overrides unittest.assertNotEqual to handle ndarrays separately. “assertNotEqual” uses the “!=” operator, but this is not implemented for ndarrays. Instead, we check that np.testing.assert_array_equal raises an assertion error, as numpy testing does not provide a assert_array_not_equal function.

Note that assertNotEqual does not work like assertEqual in unittest. Rather than allowing you to register a custom equality evaluator (e.g. with addTypeEqualityFunc()), assertNotEqual assumes the “!=” can be used with the arguments regardless of type.

Parameters:

• first (Any) –

• second (Any) –

• msg (str) –

Return type:

None

make_output_dir(prefix, directory=PosixPath('/tmp'))

Create a temporary output directory, which will be automatically removed (regardless of exceptions) on shutdown, unless logger.level is DEBUG

Parameters:

• prefix (str) – The prefix for the directory name - a random unique identifier is added to this

• dir – Location of the output directory. Defaults to “/tmp”.

• directory (Path) –

Returns:

The absolute path to the created output directory

Return type:

str

setUp()

Creates list of temporary directories that will be removed before shutdown (unless debug mode is on)

Return type:

None

tearDown()

Removes temporary output directories (unless debug mode is on)

Return type:

None

compare_or_update(path, data)

Compare the given data to what is saved in path, OR update the saved data if the –update flag was passed to the test.

Parameters:

• path (Union[str, PathLike]) –

• data (str) –

Return type:

None

compare_or_update_file(path, new_file)

Parameters:

• path (Union[str, PathLike]) –

• new_file (Union[str, PathLike]) –

Return type:

None

compare_or_update_directory(actual_dir, expected_dir)

Check the contents of actual_dir match expected_dir, OR update the expected directory if the –update flag was passed to the test.

Parameters:

• actual_dir (Union[str, PathLike]) –

• expected_dir (Union[str, PathLike]) –

Return type:

None
