Question

Angular Protractor is hitting a limit with its executeScript and executeAsyncScript functions, throwing an error of "

Is it possible to access the isolated scope of a directive with Protractor using this code snippet?

protractor.executeAsyncScript(function(callback){
    var isoScope = angular.element("div[my-directive='data']").isolateScope();
    callback(isoScope);
}).then(function(isoScope){
    console.log("Directive's isolated scope:", isoScope);
});

However, an issue arises when trying to execute the code in Chrome:

UnknownError: Unknown error: Maximum call stack size exceeded (Session info: chrome=34.0.1847.131)

javascript angularjs scope protractor

Answer №1

Avoid sending overly large or complex objects from the client to protractor. In this scenario, the isolatedScope object is too bulky.

This issue may arise with functions like executeAsyncScript(), executeScript(), and evaluate() (which internally calls executeScript()).

If you encounter a problem, try reproducing it outside of protractor first. You can easily examine the scope by right-clicking and selecting "inspect element", then entering $scope in the dev console.

If you're examining the scope for testing purposes, remember that Protractor tests are meant to be high-level "black box" tests focusing on user interactions. Testing internal states of directives should be done using DOM client unit tests instead.

One common cause of the error message `Maximum call stack size exceeded` is when a function recursively calls itself. Consider this example:

let next = async function () {
    await $nextButton.click();
    await next();
}

In this scenario, the code enters an infinite loop and triggers the error.

To prevent this issue, carefully review your code to ensure that it does not unintentionally call a function within itself.
