Catching ST errors

[freightgateone]

Is it possible to catch errors thrown by ST and handle them as I wish to?

For example catching the error that occurs when a row can not be located due to an invalid rowindex?

try {
    St.grid(locator).rowAt(index);
} catch (e) {
    // grid not found
}catch (e) {
    // row not found
}

As the ST Future APIs are queued up and executed when the components/elements are ready, any exceptions can't be caught in a traditional try-catch situation like you demonstrated above, as the actions from the Futures API will be executed after the contents of the test are parsed.

In any case, as part of an automated test run I would think it would be undesired for errors to be caught so they are instead output properly as part of the test run results, so you can then fix or improve the tests before running them again.

The Sencha Test APIs do provide a mechanism to assert that something has failed, for instance if you want to check a component doesn't exist, or you expect a particular action to always fail, you can use the "timedout" API:

ST.component('mycomponent').timedout();  // This checks the component doesn't exist
