/* This is the promise chain which drives the test execution.
|
|
|
|
suite.getCamera
|
|
This returns a promise which is resolved when the suite
|
|
acquires the camera object (i.e. returns as if one
|
|
called cameraManager.getCamera() directly). It saves
|
|
the CameraControl reference in suite.camera and will
|
|
automatically release it for you when the test is
|
|
completed.
|
|
|
|
.then(startAutoFocusFail, suite.rejectGetCamera)
|
|
If the getCamera promise is resolved, startAutoFocusFail
|
|
will be called. That function attaches a handler to
|
|
the camera test hardware to intercept the auto focus
|
|
driver call so that we can change the behaviour to
|
|
trigger an OnAutoFocusComplete(false) event. It then
|
|
calls camera.autoFocus() and returns the promise for
|
|
that camera call so that the next promise in the chain
|
|
can block waiting for that promise to be fulfilled.
|
|
|
|
If the getCamera promise is rejected,
|
|
suite.rejectGetCamera will be called. This is a helper
|
|
handler provided by the test suite; it will log
|
|
a get camera failure and fail the test via ok, and
|
|
return a new promise rejecting *without* an error
|
|
object (i.e. promise parameter is undefined). This is
|
|
important because all reject handlers further down
|
|
the promise chain will still be called due to the
|
|
failure. However since we replaced the promise with
|
|
an error object, with a promise without one, we can
|
|
use this to identify errors that have already been
|
|
handled.
|
|
|
|
.then(resolveAutoFocusFail, suite.rejectAutoFocus)
|
|
If the suite.camera.autoFocus() promise is resolved,
|
|
resolveAutoFocusFail will be called. That function
|
|
simply verifies the result from the autoFocus() call.
|
|
It should be false, given the modified behaviour we
|
|
gave the driver. Since it doesn't return a new promise
|
|
explicitly, it will generate a new promise which is
|
|
already resolved (without the focused state parameter,
|
|
will now be undefined to the next .then handler).
|
|
|
|
If the suite.camera.autoFocus() promise is rejected,
|
|
we want to fail the test case again, just like when
|
|
suite.getCamera() failed.
|
|
|
|
.then(startAutoFocusError)
|
|
Assuming the first suite.camera.autoFocus() promise
|
|
was resolved, startAutoFocusError will be called.
|
|
That function is similar to startAutoFocusFail but
|
|
now it throws an error in the intercepted auto focus
|
|
driver call in order to trigger an OnUserError(kAutoFocus)
|
|
event. It then calls and returns the promise from
|
|
suite.camera.autoFocus().
|
|
|
|
.then(suite.expectedRejectAutoFocus, rejectAutoFocusError)
|
|
Now we are expecting the previous suite.camera.autoFocus()
|
|
promise to be rejected, which would call
|
|
rejectAutoFocusError. This simply verifies that we
|
|
got the error we expected.
|
|
|
|
If, on the other hand, it somehow succeeded, we
|
|
let suite.expectedRejectAutoFocus handle it, which
|
|
similar to the suite.rejectAutoFocus method, will
|
|
fail and return an empty rejected promise.
|
|
|
|
Note that this method itself returns the promise chain.
|
|
This allows the test suite to 1) capture any unhandled
|
|
errors in the promise chain and ensure the test case
|
|
fails as a result, and 2) perform any cleanup operations
|
|
such as resetting low memory state, releasing the camera,
|
|
etc, before starting the next test.
