Testing.

See the [Testing](https://tensorflow.org/api_docs/python/tf/test) guide.

> [!NOTE]
> **Note:** `tf.compat.v1.test.mock` is an alias to the python `mock` or `unittest.mock` depending on the python version.

## Classes

[`class Benchmark`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/Benchmark): Abstract class that provides helpers for TensorFlow benchmarks.

[`class StubOutForTesting`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/StubOutForTesting): Support class for stubbing methods out for unit testing.

[`class TestCase`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/TestCase): Base class for tests that need to test TensorFlow.

## Functions

[`assert_equal_graph_def(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/assert_equal_graph_def): Asserts that two `GraphDef`s are (mostly) the same.

[`benchmark_config(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/benchmark_config): Returns a tf.compat.v1.ConfigProto for disabling the dependency optimizer.

[`compute_gradient(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/compute_gradient): Computes and returns the theoretical and numerical Jacobian. (deprecated)

[`compute_gradient_error(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/compute_gradient_error): Computes the gradient error. (deprecated)

[`create_local_cluster(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/create_local_cluster): Create and start local servers and return the associated `Server` objects.

[`get_temp_dir(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/get_temp_dir): Returns a temporary directory for use during tests.

[`gpu_device_name(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/gpu_device_name): Returns the name of a GPU device if available or the empty string.

[`is_built_with_cuda(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/is_built_with_cuda): Returns whether TensorFlow was built with CUDA (GPU) support.

[`is_built_with_gpu_support(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/is_built_with_gpu_support): Returns whether TensorFlow was built with GPU (i.e. CUDA or ROCm) support.

[`is_built_with_rocm(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/is_built_with_rocm): Returns whether TensorFlow was built with ROCm (GPU) support.

[`is_gpu_available(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/is_gpu_available): Returns whether TensorFlow can access a GPU.

[`main(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/main): Runs all unit tests.

[`test_src_dir_path(...)`](https://www.tensorflow.org/versions/r1.15/api_docs/python/tf/test/test_src_dir_path): Creates an absolute test srcdir path given a relative path.
