[Core]: While creating a quote, if a client is not already in the system allow the user via the search box to add a client on the go #64

Context

Especially in busy environments adding a client instantly would be time efficient

spacecabbie: also currently no error when trying this. (clients field empty application crashes)

Specific:

As a user, I want to be able to add a client quickly and reliably, without the application crashing when client fields are empty.

Measurable:

The time taken to add a client will be reduced by 50% and the application will no longer crash when client fields are empty.

Achievable:

The development team has the resources and skills to implement input validation and optimize the client creation process.

Relevant:

This feature directly improves user efficiency and prevents application crashes, thus enhancing user satisfaction and data integrity.

Time-bound:

This user story must be completed within the next two development sprints, ending in four weeks.

Arrange:

// 1. Create a user and authenticate them
// 2. Define an array of client data with some empty fields (e.g., 'name' => '', 'email' => 'test@example.com')
// 3. Define a route for creating clients (assuming it's named 'clients.store')

Act:

// 1. Make a POST request to the 'clients.store' route with the client data array

Assert:

// 1. Assert that the response has a 302 status code (redirect) indicating validation failure
// 2. Assert that the session has validation errors (using assertSessionHasErrors) for the empty fields (e.g., 'name')
// 3. Assert that the database does not contain a new client record with the attempted data.
