Build & Test: UCSBOrganization Edit Page

Welcome to the exciting world of frontend development! In this article, we'll dive into the process of creating and testing the Edit Page for UCSBOrganization. This is a crucial step in building a robust and user-friendly application. We will follow a structured approach, ensuring that our implementation is not only functional but also well-tested and documented. Let's get started!

Understanding the Goal: UCSBOrganization Edit Page

The primary objective of this task is to create an Edit Page for the UCSBOrganization component within our application. This page will allow users to modify existing records in the database. When a user navigates to /ucsborganization/edit/:id, where :id represents the unique identifier of a valid record, the page should be populated with the existing data. The user should then be able to modify the fields and save the changes.

Acceptance Criteria Deep Dive

• Populating the Edit Page: Upon navigating to the edit page with a valid ID, the page should fetch and display the existing data for that specific UCSBOrganization record.
• Saving Valid Changes: When the user submits the form with valid data, the changes should be saved to the database through the appropriate API endpoint.
• Handling Invalid Data: If the user enters invalid data, the changes should not be saved. Instead, the page should display informative error messages to guide the user.
• Canceling Changes: A cancel button should be implemented to allow users to discard their changes and return to the previous page without saving.
• Documentation: The pull request (PR) should include a screenshot of the new edit page and a link to the corresponding Storybook story for easy review and verification.

Achieving these criteria ensures a well-functioning and user-friendly edit experience.

Step-by-Step Implementation: Building the Edit Page

Now, let's break down the implementation process. We will follow a detailed approach to ensure accuracy and efficiency. This will involve understanding the existing components, utilizing relevant API endpoints, and creating a new page with proper functionality.

Setting Up the Environment

Before you begin, ensure your development environment is correctly configured. This includes setting the node version using nvm use 22.18.0. This ensures compatibility with the project's dependencies and avoids potential issues. Having the correct node version is crucial for the smooth operation of the project.

Code Structure and Files

1. UCSBOrganizationEditPage.js: This file will house the core logic and structure of the edit page. You'll need to replace the placeholder content with the actual implementation based on the design.
2. UCSBOrganizationEditPage.test.js: This file will contain the unit tests for the edit page, ensuring that all functionalities work as expected.
3. UCSBOrganizationEditPage.stories.js: Create this file under frontend/src/stories/pages/UCSBOrganization/. This file will enable you to visualize and interact with the UCSBOrganizationEditPage component in Storybook.

Leveraging Existing Components

To expedite the development process, utilize the code from existing components such as RestaurantEditPage.js and UCSBDatesEditPage.js. These components serve as excellent examples of how to implement edit pages, including data fetching, form handling, and error validation. Carefully analyze the code and adapt it to the specific requirements of the UCSBOrganization component, ensuring the correct API endpoints are used.

API Endpoint Considerations

Understanding the backend API endpoints is crucial for successful integration. Consult the Swagger page to identify the correct endpoints for CRUD (Create, Read, Update, Delete) operations related to UCSBOrganization. Make sure the frontend code interacts with the right endpoints to ensure data is properly saved and retrieved. Mismatched endpoints can lead to errors and data loss.

Testing the Edit Page: Ensuring Quality

Testing is a vital part of the software development lifecycle. Thorough testing will help ensure that the edit page functions correctly, handles errors gracefully, and meets all the acceptance criteria.

Unit Testing (UCSBOrganizationEditPage.test.js)

Create comprehensive unit tests in UCSBOrganizationEditPage.test.js to cover all aspects of the edit page. This includes:

• Data Population: Verify that the page correctly fetches and displays the data for the specified UCSBOrganization record when loaded.
• Form Submission: Test the form submission logic, ensuring that valid changes are saved to the database.
• Error Handling: Simulate invalid data inputs and confirm that appropriate error messages are displayed, and data is not saved.
• Cancel Functionality: Test the cancel button to ensure it navigates the user back to the previous page without saving any changes.

Running Tests

Execute the tests locally using the command npm test to verify that all tests pass. Pay close attention to any test failures and address the underlying issues to ensure complete functionality.

Mutation Coverage

Check mutation coverage locally using npx stryker run (slow) or npx stryker run -m src/main/pages/UCSBOrganization/UCSBOrganizationEditPage.js (faster for single files). Mutation testing helps to identify areas where the tests might not be covering all the code paths, improving the overall quality and reliability of the tests.

Storybook Integration: Visualizing and Interacting

Storybook offers a powerful way to visualize and interact with UI components in isolation. Creating a Storybook story for UCSBOrganizationEditPage allows developers to:

• Isolate the Component: View and interact with the edit page component independently from the rest of the application.
• Test Different States: Simulate various states (e.g., loading, success, error) to test how the component behaves under different conditions.
• Easy Collaboration: Share and showcase the component with team members and stakeholders for review and feedback.

Creating UCSBOrganizationEditPage.stories.js

Create a new file called UCSBOrganizationEditPage.stories.js under frontend/src/stories/pages/UCSBOrganization/. Model the story after examples like RestaurantEditPage.stories.js and UCSBDatesEditPage.stories.js. The story should showcase the edit page and allow interaction with the different input fields and buttons. This allows for a clean and efficient way to showcase your component.

Running Storybook

Run Storybook locally using the command npm run storybook. Open the Storybook interface in your browser and verify that the UCSBOrganizationEditPage component is displayed correctly. Interact with the component to ensure it behaves as expected.

Documentation and Code Submission: Completing the Task

Once the edit page is implemented, tested, and integrated with Storybook, it's time to prepare the code for submission.

Pull Request Description

Create a comprehensive pull request (PR) description that includes:

• A clear and concise description of the changes made.
• A screenshot of the new edit page, showing its functionality and design.
• A link to the published Storybook story for the UCSBOrganizationEditPage component, linking directly to the story for the new UCSBOrganizationEditPage component.

Code Formatting

Ensure that the code is formatted consistently using npm run format. This will automatically format your code according to the project's coding standards, improving readability and maintainability.

Linting

Check for any linting errors using npx eslint --fix . and resolve them. This will ensure that the code adheres to the project's coding style guidelines and avoids potential errors.

Team Collaboration and Sprint Completion

With the UCSBOrganizationEditPage completed, it's time to focus on assisting your team members in completing the sprint. Collaborate with your teammates, provide support, and ensure that the team is ready to submit the project by the deadline. This collaborative effort helps to enhance the overall quality and efficiency of the project. Teamwork makes the dream work!
