Feature: Plan Service
|
|
As a developer
|
|
I want to manage plans
|
|
So that I can generate and apply code changes
|
|
|
|
Scenario: Create a new plan with prompt
|
|
Given I have a plan service
|
|
When I create a plan with prompt "Add error handling"
|
|
Then the plan should be created
|
|
And the plan prompt should be "Add error handling"
|
|
And the plan should be the current plan
|
|
|
|
Scenario: Create empty plan with name
|
|
Given I have a plan service
|
|
When I create an empty plan named "feature-x"
|
|
Then the plan should be created
|
|
And the plan name should be "feature-x"
|
|
And the plan prompt should be empty
|
|
|
|
Scenario: Build a plan to generate changes
|
|
Given I have a plan service
|
|
And I have created a plan with "Generate example code"
|
|
When I build the plan
|
|
Then changes should be generated
|
|
And the changes should include file operations
|
|
|
|
Scenario: Build plan uses actor selection
|
|
Given I have a plan service with stub provider registry
|
|
And I have created a plan with "Generate example code"
|
|
When I build the plan with actor "anthropic/claude-dev"
|
|
Then changes should be generated
|
|
And the stub provider registry should record provider "anthropic" and model "claude-dev"
|
|
|
|
Scenario: Build plan fails when no provider configured
|
|
Given I have a plan service without providers configured
|
|
And I have created a plan with "Generate example code"

|
|
|
|

|
|
|
|
Scenario: List all plans
|
|
Given I have a plan service
|
|

|
|
|
|
Scenario: Switch between plans

|
|
And I have created plan "plan-a"
|
|
And I have created plan "plan-b"
|
|
When I switch to plan "plan-a"
|
|
Then "plan-a" should be the current service plan
|
|
And "plan-b" should not be current
|
|
|
|
Scenario: Continue adding to existing plan
|
|
Given I have a plan service
|
|
And I have created a plan with "Initial instructions"
|
|
When I add "Additional instructions" to the plan
|
|
Then the plan should contain both instructions
|
|
|
|
Scenario: Auto-debug build uses empty context when plan ID disappears
|
|
Given I have a temporary test directory for plan service
|
|
And I configured an auto-debug plan with a disappearing plan ID
|
|
When I run auto-debug build with missing plan context
|
|
Then the auto-debug build should fall back to an empty context
|
|
|

|
|
|
|

|
|
And the prepared LangSmith config should include a generated thread id
|
|
|
|
Scenario: Build fails when plan ID disappears mid-transaction
|
|
Given I have a temporary test directory for plan service
|
|
And I configure a stub plan service whose current plan loses its ID after the transaction

|
|
Then a PlanError should be raised with message "Plan does not have a valid ID"
|
|
|
|
Scenario: Clearing memory without forgetting history keeps cached messages
|
|
Given I have a plan service
|
|
And I stored a chat message in session "ephemeral-branch"
