[#10920] Add MC/DC coverage for checkCompulsoryFields method in Course Enroll Page

[Jagaima]

Description

This PR addresses the high priority testing for the Course Enroll Page by adding comprehensive MC/DC test coverage for the checkCompulsoryFields method.

Changes

• Added 6 MC/DC test cases covering all decision paths in student enrollment validation
• Method tested: checkCompulsoryFields with logic if ((A && B) || C || D || E) (based on page function sections)
• Conditions covered:
  • A: 100+ students validation
  • B: Empty section validation
  • C: Empty team validation
  • D: Empty name validation
  • E: Empty email validation

Test Coverage

The tests ensure MC/DC coverage by proving each condition independently affects validation:

1. Valid enrollment - All fields filled correctly
2. Empty email - Tests mandatory email field
3. Empty name - Tests mandatory name field
4. Empty team - Tests mandatory team field
5. Large class organized - 100+ students with sections
6. Large class disorganized - 100+ students without sections

Verification

✅ All 6 tests pass successfully
✅ Increases test coverage from 0% to 100% MC/DC
✅ Addresses high priority testing for Course Enroll Page
