## Overriding dependencies during testing { #overriding-dependencies-during-testing }

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

 * If {@link #ignoreException} is set to true, any exceptions thrown during the delay will be caught
 * and ignored. Otherwise, they will be re-thrown as {@link CrawlerSystemException}.

    /**
     * Indicates whether exceptions during the delay process should be ignored.

         * @param request the request data
         * @param exceptionList the list of exceptions that occurred during retries

        void onRequestEnd(FaultTolerantClient client, RequestData request, List<Exception> exceptionList);

specifics of a local system, we rely on hermetic Python (see
[rules_python](https://github.com/bazelbuild/rules_python)) for all build
and test commands executed via Bazel. This means that your system Python
installation will be ignored during the build and Python interpreter itself
as well as all the Python dependencies will be managed by bazel directly.

### Specifying Python version

The hermetic Python version is controlled by `HERMETIC_PYTHON_VERSION`

    PROCESS_CHILD_URLS_BY_EXCEPTION,
    /** Indicates processing a child URL due to an exception. */
    PROCESS_CHILD_URL_BY_EXCEPTION,
    /** Indicates an access exception during crawling. */
    CRAWLING_ACCESS_EXCEPTION,
    /** Indicates a general exception during crawling. */
    CRAWLING_EXCEPTION,
    /** Indicates no URL is available in the queue. */
    NO_URL_IN_QUEUE,
    /** Indicates the start of a crawler thread. */

The recommended way to handle the *startup* and *shutdown* is using the `lifespan` parameter of the `FastAPI` app as described above. If you provide a `lifespan` parameter, `startup` and `shutdown` event handlers will no longer be called. It's all `lifespan` or all events, not both.

You can probably skip this part.

///

There's an alternative way to define this logic to be executed during *startup* and during *shutdown*.

	PutObjectMetadata(context.Context, string, string, ObjectOptions) (ObjectInfo, error)
	DecomTieredObject(context.Context, string, string, FileInfo, ObjectOptions) error

	// ObjectTagging operations
	PutObjectTags(context.Context, string, string, string, ObjectOptions) (ObjectInfo, error)
	GetObjectTags(context.Context, string, string, ObjectOptions) (*tags.Tags, error)
