### create\_test

```python
dbnl.experimental.create_test(*, test_spec_dict: TestSpecDict) → dict[str, Any]
```

Create a new Test Spec

* **Parameters:test\_spec\_dict** – A dictionary containing the Test Spec schema.
* **Raises:**
  * **DBNLNotLoggedInError** – dbnl SDK is not logged in.
  * **DBNLAPIValidationError** – Test Spec does not conform to expected format.

```

Create a Test Generation Session

* **Parameters:**
  * **run** – The Run to use when generating tests.
  * **columns** – List of columns in the Run to generate tests for. If None, all\
    columns in the Run will be used, defaults to None. If a list of strings, each string is a column name.\
    If a list of dictionaries, each dictionary must have a ‘name’ key, and the value is the column name.

* **Returns:**\
  The TestGenerationSession that was created.

#### Examples:

```python
import dbnl
dbnl.login()


run = dbnl.get_run(run_id="run_0000000")
dbnl.experimental.create_test_generation_session(
    run=run,
    columns=["col1", "col4"],
)
```

```python
dbnl.experimental.create_test_recalibration_session(*, test_session: TestSession, feedback: str, test_ids: list[str] | None = None) → TestRecalibrationSession

Create a Test Recalibration Session by redefining the expected output for tests in a Test Session

* **Parameters:**
  * **test\_session** – Test Session to recalibrate

  Test Recalibration Session

#### IMPORTANT

If some generated Tests failed when they should have passed and some passed when they should have failed,\
you will need to submit 2 separate calls, one for each feedback result.
