Feature: Add unit_tests for is_main_network()

[Debarghya-Banerjee]

Trac Ticket: Core-59981

Description:

• This pull request introduces the initial set of unit tests for the is_main_network() function. The tests are designed to verify the function's behavior in both multisite and single-site scenarios.

Changes Made:

• Added Multisite Tests:

  • Class: Tests_Multisite_IsMainNetwork

  • Purpose: Tests the behavior of is_main_network() for valid and invalid network IDs within a multisite environment.

  • Test Cases:

    • Valid network IDs that should return true:

      • null
      • 1 (main network)

    • Invalid network IDs that should return false:

      • 2
      • 0
      • Empty string

• Added Single-Site Tests:

  • Class: Tests_Functions_IsMainNetwork

  • Purpose: Tests the behavior of is_main_network() in a single-site context.

  • Test Cases:

    • Valid network IDs that should return true:
      • null
      • 1
      • 0
      • Empty string
      • Non-main network ID (2) which is also tested to ensure the function handles it correctly.

Benefits:

• Coverage for Multisite and Single-Site

  • Ensures that the is_main_network() function is thoroughly tested in different contexts.

• Early Detection of Issues

  • The introduction of these tests will help catch any bugs or unexpected behavior early in the development process.

Testing:

• The tests are designed to be run in the WordPress environment using PHPUnit.

• All tests have been verified to pass successfully.
