Update/Add Unit Tests For ActionValidationService Prerequisites

by ADMIN 64 views

Introduction

Testing is a crucial aspect of software development, ensuring that the code works as expected and meets the required standards. In the context of the ActionValidationService, testing is essential to guarantee that the prerequisite logic functions correctly after refactoring. This article outlines the tasks and steps required to update and add unit tests for ActionValidationService Prerequisites, specifically focusing on the evaluation of JSON Logic prerequisites using the ConditionEvaluatorService.

Goal

The primary goal of this task is to update existing unit tests and add new ones for ActionValidationService.isValid, ensuring that the prerequisite logic works correctly after the refactoring. The new tests must verify that isValid correctly invokes the ConditionEvaluatorService for each prerequisite rule and handles the boolean results appropriately, covering various JSON Logic scenarios.

Tasks

Identify/Remove Old Tests

The first step is to locate unit tests for ActionValidationService and identify and remove any tests specifically targeting the old _checkSinglePrerequisite method. This is necessary to ensure that the new tests do not conflict with the existing ones and to prevent any potential issues.

Setup Mocking

In the test setup for ActionValidationService, mock the ConditionEvaluatorService dependency. The mock should allow checking if its evaluate method was called, with which arguments (rule, context), and allow controlling the boolean value it returns for specific test cases. Additionally, mock EntityManager as needed to provide mock entities and component data for context assembly.

Update Existing isValid Tests

Review existing tests for isValid that might have implicitly tested prerequisites. Update them to:

  • Use mock action definitions containing valid JSON Logic prerequisites.
  • Configure the mock ConditionEvaluatorService.evaluate to return true or false as needed for the specific test case.
  • Assert that isValid returns the expected overall boolean result based on the mock evaluator's return value.

Add New Prerequisite Tests

Create new test cases specifically for prerequisite evaluation logic within isValid:

  • Test Case: Action with NO prerequisites should pass (assuming other checks pass).
  • Test Case: Action with one simple prerequisite (e.g., "==" [1, 1]). Mock evaluate to return true. Assert isValid returns true.
  • Test Case: Action with one simple prerequisite. Mock evaluate to return false. Assert isValid returns false.
  • Test Case: Action with multiple prerequisites. Mock evaluate to return true for all. Assert isValid returns true.
  • Test Case: Action with multiple prerequisites. Mock evaluate to return false for the first one. Assert isValid returns false and verify evaluate was only called once (or verify based on implementation detail).
  • Test Case: Action with multiple prerequisites. Mock evaluate to return true for the first, false for the second. Assert isValid returns false.
  • Verify Context Assembly: Create a test where you pass a specific actorEntity and targetEntity to isValid. Assert that the mock conditionEvaluatorService.evaluate was called with a JsonLogicEvaluationContext containing correctly structured actor and target properties (check IDs and potentially mock component accessor calls if feasible). Use complex JSON logic rules involving actor.components... and target.components... in the test definition.

Refine Mocks and Assertions

Ensure mocks accurately reflect the service interactions and assertions clearly the expected outcomes and service calls.

Acceptance Criteria

  • Unit tests for the old _checkSinglePrerequisite are removed.
  • Unit tests for ActionValidationService.isValid exist that specifically cover the prerequisite evaluation logic.
  • Tests use mock action definitions with JSON Logic prerequisites.
  • Tests mock the ConditionEvaluatorService and verify its evaluate method is called correctly (with rule and context) for each prerequisite.
  • Tests verify that isValid returns the correct boolean result based on the outcome of prerequisite evaluations (including early exit on failure).
  • At least one test verifies the structure of the JsonLogicEvaluationContext passed to the evaluator.
  • All tests pass.

Dependencies

  • Ticket 3.3: ActionValidationService must be refactored to use ConditionEvaluatorService.
  • Familiarity with the project's testing framework (e.g., Jest, Mocha) and mocking libraries.

Estimate

Medium/Large (Requires careful test design, mocking, and verification of interactions).
