The `shapedetection-helpers.js` tests require implementations of
|
|
the `FaceDetectionTest`, `BarcodeDetectionTest` and `TextDetectionTest`
|
|
interfaces, which should emulate platform shape detection backends.
|
|
|
|
The `FaceDetectionTest` interface is defined as:
|
|
|
|
```
|
|
class FaceDetectionTest {
|
|
async initialize(); // Sets up the testing environment.
|
|
async reset(); // Frees the resources.
|
|
MockFaceDetectionProvider(); //Returns `MockFaceDetectionProvider` interface.
|
|
};
|
|
|
|
class MockFaceDetectionProvider {
|
|
getFrameData(); //Gets frame data of detection result.
|
|
getMaxDetectedFaces(); //Gets value of `maxDetectedFaces` in `FaceDetector` constructor
|
|
getFastMode(); //Gets value of `fastMode` in `FaceDetector` constructor
|
|
};
|
|
```
|
|
|
|
The Chromium implementation of the `FaceDetectionTest` interface is located in
|
|
[mock-facedetection.js](../resources/chromium/mock-facedetection.js).
|
|
|
|
The `BarcodeDetectionTest` interface is defined as:
|
|
|
|
```
|
|
class BarcodeDetectionTest {
|
|
async initialize(); // Sets up the testing environment.
|
|
async reset(); // Frees the resources.
|
|
MockBarcodeDetectionProvider(); //Returns `MockBarcodeDetectionProvider` interface.
|
|
};
|
|
|
|
class MockBarcodeDetectionProvider {
|
|
async enumerateSupportedFormats(); //Enumerates supported formats
|
|
getFrameData(); //Gets frame data of detection result.
|
|
getFormats(); //Gets value of `formats` in `BarcodeDetector` constructor
|
|
simulateNoImplementation(); // simulate a 'no implementation available' case
|
|
};
|
|
```
|
|
|
|
The Chromium implementation of the `BarcodeDetectionTest` interface is located in
|
|
[mock-barcodedetection.js](../resources/chromium/mock-barcodedetection.js).
|
|
|
|
The `TextDetectionTest` interface is defined as:
|
|
|
|
```
|
|
class TextDetectionTest {
|
|
async initialize(); // Sets up the testing environment.
|
|
async reset(); // Frees the resources.
|
|
MockTextDetection(); //Returns `MockTextDetection` interface.
|
|
};
|
|
|
|
class MockTextDetection {
|
|
getFrameData(); //Gets frame data of detection result.
|
|
};
|
|
```
|
|
|
|
The Chromium implementation of the `TextDetectionTest` interface is located in
|
|
[mock-textdetection.js](../resources/chromium/mock-textdetection.js).
|
|
|
|
Other browser vendors should provide their own implementations of
|
|
the `FaceDetectionTest`, `BarcodeDetectionTest` and `TextDetectionTest`
|
|
interfaces.
