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.
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.
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.
Other browser vendors should provide their own implementations of the FaceDetectionTest
, BarcodeDetectionTest
and TextDetectionTest
interfaces.
