Use cases are derived from `FRs.md` (user stories) and `meta-arch.md`. Each Feature name matches the corresponding user story; scenarios focus on observable behavior without restating story details.
|
||||
|
||||
```gherkin
|
||||
Feature: PDF browser
|
||||
|
||||
Scenario: Open a PDF and navigate pages
|
||||
Given a PDF document is available
|
||||
When the user opens the document
|
||||
Then the first page is displayed
|
||||
And the user can move to the next or previous page
|
||||
|
||||
Scenario: Jump to a specific page
|
||||
Given a multi-page PDF is open
|
||||
When the user selects a specific page number
|
||||
Then that page is displayed
|
||||
|
||||
Scenario: Select a page for signing
|
||||
Given a PDF is open
|
||||
When the user marks the current page for signing
|
||||
Then the page is set as the signature target
|
||||
```
|
||||
|
||||
```gherkin
|
||||
Feature: load signature picture
|
||||
|
||||
Scenario: Import a signature image
|
||||
Given a PDF page is selected for signing
|
||||
When the user chooses a signature image file
|
||||
Then the image is loaded and shown as a signature asset
|
||||
|
||||
Scenario Outline: Handle invalid or unsupported files
|
||||
Given the user selects "<file>"
|
||||
When the app attempts to load the image
|
||||
Then the user is notified of the issue
|
||||
And the image is not added to the document
|
||||
|
||||
Examples:
|
||||
| file |
|
||||
| corrupted.png |
|
||||
| signature.bmp |
|
||||
| empty.jpg |
|
||||
```
|
||||
|
||||
```gherkin
|
||||
Feature: geometrically adjust signature picture
|
||||
|
||||
Scenario: Resize and move the signature within page bounds
|
||||
Given a signature image is placed on the page
|
||||
When the user drags handles to resize and drags to reposition
|
||||
Then the size and position update in real time
|
||||
And the signature remains within the page area
|
||||
|
||||
Scenario: Lock aspect ratio while resizing
|
||||
Given a signature image is selected
|
||||
When the user enables aspect ratio lock and resizes
|
||||
Then the image scales proportionally
|
||||
```
|
||||
|
||||
```gherkin
|
||||
Feature: graphically adjust signature picture
|
||||
|
||||
Scenario: Remove background
|
||||
Given a signature image is selected
|
||||
When the user enables background removal
|
||||
Then near-white background becomes transparent in the preview
|
||||
And the user can apply the change
|
||||
|
||||
Scenario: Adjust contrast and brightness
|
||||
Given a signature image is selected
|
||||
When the user changes contrast and brightness controls
|
||||
Then the preview updates immediately
|
||||
And the user can apply or reset adjustments
|
||||
```
|
||||
|
||||
```gherkin
|
||||
Feature: draw signature
|
||||
|
||||
Scenario: Draw with mouse or touch and place on page
|
||||
Given an empty signature canvas
|
||||
When the user draws strokes and confirms
|
||||
Then a signature image is created
|
||||
And it is placed on the selected page
|
||||
|
||||
Scenario: Clear and redraw
|
||||
Given a drawn signature exists in the canvas
|
||||
When the user clears the canvas
|
||||
Then the canvas becomes blank
|
||||
|
||||
Scenario: Undo the last stroke
|
||||
Given multiple strokes were drawn
|
||||
When the user chooses undo
|
||||
Then the last stroke is removed
|
||||
```
|
||||
|
||||
```gherkin
|
||||
Feature: save signed PDF
|
||||
|
||||
Scenario: Export the signed document to a new file
|
||||
Given a PDF is open and contains at least one placed signature
|
||||
When the user saves/exports the document
|
||||
Then a new PDF file is saved at specified full path, location and file name
|
||||
And the signatures appear on the corresponding page in the output
|
||||
And keep other unchanged content(pages) intact in the output
|
||||
|
||||
Scenario: Vector-accurate stamping into PDF page coordinates
|
||||
Given a signature is placed with a position and size relative to the page
|
||||
When the user saves/exports the document
|
||||
Then the signature is stamped at the exact PDF page coordinates and size
|
||||
And the stamp remains crisp at any zoom level (not rasterized by the screen)
|
||||
And other page content remains vector and unaltered
|
||||
|
||||
Scenario: Prevent saving when nothing is placed
|
||||
Given a PDF is open with no signatures placed
|
||||
When the user attempts to save
|
||||
Then the user is notified there is nothing to save
|
||||
|
||||
Scenario: Loading sign when exporting/saving files
|
||||
Given a signature is placed with a position and size relative to the page
|
||||
When the user starts exporting the document
|
||||
And the export process is not yet finished
|
||||
Then the user is notified that the export is still in progress
|
||||
And the user cannot edit the document
|
||||
|
||||
```
|
||||
The Gherkin scenarios live in runnable BDD feature files under `test/features/`.
