How to test in SAPUI5 with OPA5 if a dialog is successfully closed? (Negative testing) - sapui5

Question

I wonder how to test with OPA5 if a Dialog is successfully closed after pressing the corresponding button.
This is how I test if the dialog is open:
{
// ...
iShouldSeeTheSortDialog: function () {
return this.waitFor({
controlType: "sap.m.ViewSettingsDialog",
id: "sortDialog",
fragmentId: "sortFragment",
success: function () {
Opa5.assert.ok(true, "The sort dialog is open");
},
errorMessage: "Did not find the sort dialog control"
});
},
}
Now I'm looking for the exact opposite test case. I would like to search for the sortDialog and throw a success if it is not found anymore.
Could you please suggest a solution?

I found the answer myself, maybe it will be helpful for someone else.
If you want to check if a dialog has been closed but not destroyed, you can do it this way:
{
//..
iShouldNotSeeDialog: function () {
return this.waitFor({
id: "dialogID",
visible: false,
success: function (oDialog) {
Opa5.assert.notOk(oDialog.getVisible(), "Dialog is not visible -- OK");
},
errorMessage: "Checking Field: dialogID -- Assertion Failed"
});
}
}
If you want to check if a dialog has been destroyed, you can do this as follows:
{
//..
iShouldNotSeeDialog: function () {
return this.waitFor({
success: function () {
var bExists = (Opa5.getJQuery()("#" + "dialogID").length > 0);
Opa5.assert.notOk(bExists, "Dialog doesn't exist -- OK");
},
errorMessage: "-- Assertion Failed"
});
}
}
