Testing Vuex Prompt Module Integration in vue-cli

This test suite validates the Vuex prompt module functionality in Vue CLI, ensuring proper plugin configuration and user interaction flows. It verifies the correct implementation of Vuex feature selection and corresponding plugin setup.

Test Coverage Overview

The test suite provides targeted coverage for the Vuex prompt module integration.

Key areas tested include:

Feature selection prompt configuration
Plugin registration verification
Expected options validation
Prompt module assertion workflow

Implementation Analysis

The testing approach utilizes Jest’s mocking capabilities to isolate the prompt module functionality. It implements a structured assertion pattern using Vue CLI’s test utilities to validate prompt configurations and plugin setup outcomes.

Technical implementation features:

File system and inquirer mocking
Specialized prompt module assertion utilities
Plugin configuration validation

Technical Details

Testing tools and configuration:

Jest test framework
@vue/cli-test-utils assertion helpers
Mock implementations for fs and inquirer
Structured test expectations for prompts and options

Best Practices Demonstrated

The test implementation showcases strong testing practices through isolated component testing and comprehensive validation.

Notable practices include:

Clear test case organization
Effective dependency mocking
Structured expectations definition
Async/await pattern usage
Modular test utility implementation
