| 21 | + |
| 22 | +| Method | Purpose | Key Arguments | Expected Behaviour | |
| 23 | +|--------------------------------------|-------------------------------------------------------------------------|------------------------------|--------------------| |
| 24 | +| `invite_surveillance_subjects_early` | Generates health check forms and invites a surveillance subject early. | `screening_centre_id` (`str`)| Navigates UI, recalculates due count, finds subject, generates forms, returns NHS number. | |
| 25 | +| `find_early_invite_subjects` | Finds an eligible subject for early surveillance invitation. | `screening_centre_id` (`str`), `surveillance_due_count_date` (`str`) | Returns NHS number of eligible subject. | |
| 26 | + |
| 27 | +--- |
| 28 | + |
| 29 | +## Main Methods |
| 30 | + |
| 31 | +### `invite_surveillance_subjects_early` |
| 32 | + |
| 33 | +Generates health check forms and invites a surveillance subject early by automating the relevant UI steps. |
| 34 | + |
| 35 | +**Arguments:** |
| 36 | + |
| 37 | +- `screening_centre_id` (`str`): The screening centre ID for which to generate forms and invite a subject. |
| 38 | + |
| 39 | +**How it works:** |
| 40 | + |
| 41 | +1. Navigates to the Surveillance page and then to the Produce Health Check Forms page. |
| 42 | +2. Sets the "Surveillance Due Count Volume" to 1. |
| 43 | +3. Clicks the "Recalculate" button to update the due count. |
| 44 | +4. Retrieves the current "Surveillance Due Count Date" from the UI. |
| 45 | +5. Finds an eligible subject for early invitation using the due count date and centre ID. |
| 46 | +6. Clicks the "Generate Health Check Forms" button. |
| 47 | +7. Returns the NHS number of the invited subject. |
| 48 | + |
| 49 | +**Returns:** |
| 50 | + |
| 51 | +- `str`: The NHS number of the early-invite subject. |
| 52 | + |
| 53 | +--- |
| 54 | + |
| 55 | +### `find_early_invite_subjects` |
| 56 | + |
| 57 | +Finds an eligible subject for early surveillance invitation based on the due count date and screening centre. |
| 58 | + |
| 59 | +**Arguments:** |
| 60 | + |
| 61 | +- `screening_centre_id` (`str`): The screening centre ID. |
| 62 | +- `surveillance_due_count_date` (`str`): The due count date as a string. |
| 63 | + |
| 64 | +**How it works:** |
| 65 | + |
| 66 | +1. Uses the `SubjectRepository` to query the database for a subject eligible for early surveillance invitation. |
| 67 | +2. Returns the NHS number of the found subject. |
| 68 | + |
| 69 | +**Returns:** |
| 70 | + |
| 71 | +- `str`: The NHS number of the eligible subject. |
| 72 | + |
| 73 | +--- |
| 74 | + |

| 77 | +Before using the Generate Health Check Forms utility, ensure that the following prerequisites are met: |
| 78 | + |
| 79 | +1. **UI Access**: The utility requires access to the BCSS UI and a valid Playwright `Page` object. |
| 80 | +2. **Database Access**: The utility uses the `SubjectRepository` to query the database for eligible subjects. |
| 81 | +3. **Screening Centre ID**: You must provide a valid screening centre ID for which to generate forms and invite subjects. |
| 82 | + |
| 83 | +--- |
| 84 | + |
| 85 | +## Supporting Classes |
| 86 | + |

| 89 | +- `BasePage` — Provides navigation and common UI actions. |
| 90 | +- `SurveillancePage` — Handles navigation to the surveillance section. |
| 91 | +- `ProduceHealthCheckFormsPage` — Interacts with the health check forms UI. |
| 92 | +- `SubjectRepository` — Queries the database for eligible subjects. |
| 93 | + |
| 94 | +--- |
| 95 | + |
| 96 | +## Example Usage |
| 97 | + |
| 98 | +```python |
| 99 | +from utils.generate_health_check_forms_util import GenerateHealthCheckFormsUtil |
| 100 | + |
| 101 | +# Assume you have a Playwright page object and a valid screening centre ID |
| 102 | +page = ... # Playwright Page object |
| 103 | +screening_centre_id = "12345" |
| 104 | + |
| 105 | +# Create the utility |
| 106 | +health_check_util = GenerateHealthCheckFormsUtil(page) |
| 107 | + |
| 108 | +# Invite a surveillance subject early and generate health check forms |
| 109 | +nhs_no = health_check_util.invite_surveillance_subjects_early(screening_centre_id) |
| 110 | + |
| 111 | +print(f"Invited subject NHS number: {nhs_no}") |
| 112 | +``` |
