Using the Test Suite Functions and Properties

8-17

This example shows the basic workflow of creating and running a test using some of the

functions outlined in the previous section.

Get installed hardware information recognizable using the winvideo adaptor.

info = imaqhwinfo('winvideo');

Identify the Device IDs.

info.DeviceIDs

Get information about available formats for the camera under test identified in the last

step. If it is the first camera, use DeviceId of 1.

info.DeviceInfo(1).SupportedFormats

Choose a format, for example MJPG_800x600, and create the test object, with an

estimated frame rate of 15.

testObj = imaqkit.AdaptorTest.createTest('winvideo', 1, 'MJPG_800x600', 15);

By default, tests create verbose logs. To run tests with concise logs set the ConciseLog

property to true and then run tests.

testObj.ConciseLog = true;

To run individual tests, call specific test functions, such as:

testObj.runObjectCreationAndPreviewTest;

testObj.runInteractiveDevicePropertiesTest;

Run all automated tests.

testObj.runAllAutomatedTests;
