+# Atlas Data Lake Tests
+
+## Introduction
+
+The YAML and JSON files in this directory are platform-independent tests that drivers can use to assert compatibility
+with [Atlas Data Lake](https://www.mongodb.com/docs/datalake/). These tests utilize the
+[Unified Test Format](../../unified-test-format/unified-test-format.md).
+
+Several prose tests, which are not easily expressed in YAML, are also presented in this file. Those tests will need to
+be manually implemented by each driver.
+
+## Test Considerations
+
+Running these integration tests will require a running `mongohoused` with data available in its `test.driverdata`
+collection. See the
+[ADL directory in drivers-evergreen-tools](https://github.com/mongodb-labs/drivers-evergreen-tools/tree/master/.evergreen/atlas_data_lake)
+and [10gen/mongohouse README](https://github.com/10gen/mongohouse/blob/master/README.md) for more information.
+
+The test runner for Atlas Data Lake testing MUST NOT drop the collection and/or database under test. In contrast to most
+other tests, which insert their own data fixtures into an empty collection, the data for these tests is specified in the
+`mongohoused` configuration file.
+
+Additionally, the test runner MUST NOT execute `killAllSessions` (see:
+[Terminating Open Transactions](../../unified-test-format/unified-test-format.md#terminating-open-transactions)) when
+connected to Atlas Data Lake.
+
+## Prose Tests
+
+The following tests MUST be implemented to fully test compatibility with Atlas Data Lake.
+
+### 1. Support for `killCursors` command
+
+Test that the driver properly constructs and issues a
+[killCursors](https://www.mongodb.com/docs/manual/reference/command/killCursors/) command to Atlas Data Lake. For this
+test, configure an APM listener on a client and execute a query on the `test.driverdata` collection that will leave a
+cursor open on the server (e.g. specify `batchSize=2` for a query that would match 3+ documents). Drivers MAY iterate
+the cursor if necessary to execute the initial `find` command but MUST NOT iterate further to avoid executing a
+`getMore`.
+
+Observe the CommandSucceededEvent event for the `find` command and extract the cursor's ID and namespace from the
+response document's `cursor.id` and `cursor.ns` fields, respectively. Destroy the cursor object and observe a
+CommandStartedEvent and CommandSucceededEvent for the `killCursors` command. Assert that the cursor ID and target
+namespace in the outgoing command match the values from the `find` command's CommandSucceededEvent. When matching the
+namespace, note that the `killCursors` field will contain the collection name and the database may be inferred from
+either the `$db` field or accessed via the CommandStartedEvent directly. Finally, assert that the `killCursors`
+CommandSucceededEvent indicates that the expected cursor was killed in the `cursorsKilled` field.
+
+Note: this test assumes that drivers only issue a `killCursors` command internally when destroying a cursor that may
+still exist on the server. If a driver constructs and issues `killCursors` commands in other ways (e.g. public API),
+this test MUST be adapted to test all such code paths.
+
+### 2. Connect without authentication
+
+Test that the driver can establish a connection with Atlas Data Lake without authentication. For these tests, create a
+MongoClient using a valid connection string without auth credentials and execute a ping command.
+
+### 3. Connect with authentication
+
+Test that the driver can establish a connection with Atlas Data Lake with authentication. For these tests, create a
+MongoClient using a valid connection string with SCRAM-SHA-1 and credentials from the drivers-evergreen-tools ADL
+configuration and execute a ping command. Repeat this test using SCRAM-SHA-256.
