Verify DAG version displayed correctly in UI when DAG structure changes between two DAG runs

1. Create and run DAG Version 1.
2. Modify DAG to Version 2.

UI

displays correct DAG structure and code for each version with a version change indicator.

Functional

Pass

TC_AIP65_002

Verify a new DAG version is created on updating any DAG params

1. Try Updating DAG params

A new DAG version should be created in the `DAG_version` table.

Functional

Pass

TC_AIP65_003

Verify changing task implementation does not create a new DAG version

1. Try to change any task implementation.

Changing task implementation should not create a new DAG Version.

Functional

Pass

Ensure removed tasks are correctly shown in the grid view

1. Create a DAG with 3 tasks and run.
2. Modify DAG to remove a task and run again.
3. Check grid view for both DAG runs.

Removed tasks are shown without status boxes, and the toggle to exclude them works.

Verified backend.

TC_AIP65_005

Verify that non-structural (e.g., task rename) DAG code changes are reflected properly in the UI

1. Modify a DAG without changing task structure.
2. Run tasks and observe the UI.

Version change indicator appears, and the tooltip reflects version changes between task instances.

Check UI for task reordering animation when an older DAG version is selected

1. Run DAG in Version 1 and then modify it to Version 2.
2. Click on an older DAG run in the UI.

Rows animate to correct positions, and tasks are reordered accordingly.

Ensure the clear button is disabled for removed tasks with proper explanation

1. Remove a task from the DAG.
2. Try to clear the removed task in the UI.

The clear button is disabled with a tooltip explanation.

Validate DAG version tracking at TaskInstance try level

1. Run a task instance multiple times with DAG changes in between.
2. Navigate through task instance attempts.

Each attempt reflects the correct DAG version, with version history accessible.

Functional

Pass

TC_AIP65_009

Test behavior when clearing an entire DAG run with older code

1. Clear all tasks in a completed DAG run.
2. Observe if the latest DAG version code is used.

Entire DAG run re-executes using the latest DAG version, with a clear indication in the UI.

Functional

Pass

TC_AIP65_010

Verify toggling between DAG code versions in code view

1. Run a DAG with multiple versions.
2. Switch between versions in the code view.

Code view updates to show the selected version accurately.

Functional

Pass

TC_AIP65_011

Test task retries with DAG version change

1. Run a task that fails in DAG

Version 
2. Modify DAG to Version 2 and retry.
3. Observe retry behavior in UI.

Task is retried with Version 2 DAG code, and the version change is indicated.

Functional

Pass

TC_AIP65_012

Check version details in task instance details

1. View task instance details in the UI.
2. Check if version details are displayed for each task.

Task instance details show the version.

Functional

Pass

TC_AIP65_013

Validate UI display when selecting DAG runs from different versions

1. Select different DAG runs from older and newer versions.
2. Compare the UI outputs.

Each DAG run displays its corresponding version, with an indicator in the UI.

TC_AIP65_014

Verify the representation of failed tasks from older DAG versions

1. Run a task with Version 1 that fails.
2. Modify the DAG and run again.

Failed tasks from Version 1 remain represented as failed, with a version indicator.

Validate task dependencies after DAG version changes

1. Modify the DAG with added/deleted dependencies.
2. Run the updated DAG and check task dependencies.

Dependencies are updated in the UI according to the

Latest DAG version, with proper visualization.

Functional

Pass

TC_AIP65_018

Test version change behavior when a task is skipped due to dependencies

1. Modify a DAG to skip a task based on conditions.
2. Check the task's behavior across different versions.

Skipped tasks are shown with their respective version history in the UI.

Functional

Pass

Verify

`serialized_dag`, `task_instance`, and `dag_code` tables have a new field as `dag_version_id`

1. Connect to the database.
2. Verify the tables have a new field as `dag_version_id`.

The tables have a new field as `dag_version_id`.

Database

Pass

TC_AIP65_020

Verify a new table `DagVersion` is created to track different DAG versions

1. Connect to the database and check.
