Add Task Version Acceptance Tests

[cppwfs]

Feature: Task versioning
Registering multi versioned task apps and selecting versions for launch.

• Scenario: I want to create a task app with 1 version

1. Given A task with 1 versions
2. And I create a task definition
3. When I launch task definition using default app version
4. Then Task should succeed
5. And It launches the specified version

• Scenario: I want to create a task app with 2 versions using default version

1. Given A task with 2 versions
2. And I create a task definition
3. When I launch task definition using default app version
4. Then Task should succeed
5. And It launches the specified version

• Scenario: I want to create a task app with 2 versions using new version

1. Given A task with 2 versions
2. And I create a task definition
3. When I launch task definition using version 2 of app
4. Then Task should succeed
5. And It launches the specified version

• Scenario: When no version is specified previous used version should be used.

1. Given A task with 2 versions
2. And I create a task definition
3. And I launch task definition using version 2 of app
4. When I launch task definition using no app version
5. Then Task should succeed
6. And It launches the specified version

• Scenario: I want to create a task app with 1 version run invalid version

1. Given A task with 1 versions
2. And I create a task definition
3. When I launch task definition using version 2 of app
4. Then Task should fail

• Scenario: Invalid version usage should not affect subsequent default launch

1. Given A task with 2 versions
2. And I create a task definition
3. And I launch task definition using version 2 of app
4. When I launch task definition using default app version
5. Then Task should succeed
6. And It launches the specified version

• Scenario: Deleting a previously used version should fail if relaunched.

1. Given A task with 2 versions
2. And I create a task definition
3. And I launch task definition using version 2 of app
4. And I unregister version 2 of app
5. When I launch task definition using version 2 of app
6. Then Task should fail

• Scenario: Changing the app default version and running between changes should be successful

1. Given A task with 2 versions
2. And I create a task definition
3. And I launch task definition using default app version
4. And I set the default to version 2 of the app
5. When I launch task definition using default app version
6. Then Task should succeed
7. And The version for the task execution should be version 2

• Scenario: Rolling back default to previous version and running should be successful

1. Given A task with 2 versions
2. And I create a task definition
3. And I launch task definition using default app version
4. And I set the default to version 2 of the app
5. And I launch task definition using default app version
6. And I set the default to version 1 of the app
7. When I launch task definition using default app version
8. Then Task should succeed
9. And The version for the task execution should be version 1

• Scenario: Unregistering app should prevent task definition launch

1. Given A task with 1 versions
2. And I create a task definition
3. And I launch task definition using default app version
4. And I unregister version 1 of app
5. When I launch task definition using default app version
6. Then Task should fail
