为什么不是在Protractor中使用executeScript创建的对象

Question

I have this code inside a describe in a protractor script that tests an angular js app.

beforeEach(function() {
  browser.get('index.html#/device_list');
  browser.executeScript("chrome.bluetooth = {};");
  browser.executeScript("console.log('test')");
  browser.executeScript("alert('test')");
});

Without this code the tests run and fail as expected. When I add this code and run the script the object isn't created, the console log isn't printed but an alert is created (and throws an async error as expected).

I have tried it without the alert and their is still no object or log.

Why is this? Is it possible to create a simple object which can be used by a test using executeScript in protractor? If not is there another way of doing it that doesn't involve creating a service?

I'm using this code inside the Protractor script to look for the console log.

browser.manage().logs().get('browser').then(function(browserLog) {
    if(browserLog.length > 0) {
        console.log(browserLog);
    }
});

Answer 1

Logging only shows error-level logs.

You'd need to do:

browser.executeScript("console.error('test')");

Answer 2

executeScript runs in the browser. If you are expecting to see the log in your node process it will not be there. It I will in you browser's log.
