How to write an integration test (protractor) for multi-uploading files in Chrome?

Question

Angular

Hello everyone
I am solving the problem of testing a multi-file upload form in a browser
For multi-upload, the angular-file-upload module is used ( https://github.com/nervgh/angular-file-upload )
The form needs to be tested in two browsers in IE 11 version and Chrome
Yes the condition that during multi-upload the number of simultaneously downloaded files should not be more than 5
Ok, for testing I use Protractor (e2e test framework based on WebDriverJS)
Here is the test code itself

it('A user attaches fileы with correct existantion', function () {
        var validFile = '../test/filesToUpload/testxlsx.xlsx',
            validFile2 = '../test/filesToUpload/testxls.xls',
        var absolutePath = path.resolve(__dirname, validFile);
        var absolutePath2 = path.resolve(__dirname, validFile2);
        $('#ifile').sendKeys('"' +absolutePath2 + '" "' +absolutePath +'"');
        var absolutePath = path.resolve(__dirname, invalidFile);
        var errorMessageElement = $('.contactForm__errorMessage');
        expect(errorMessageElement.getText()).toEqual('');
    });

Let me explain a little
In Chrome (and in IE) when selecting multiple files for multi-upload, file names are enclosed in quotes and are written with a space.
I run the test - in IE everything is ok (yes, in IE it's not strange), but in Chrome the test fails with an error:
I.e. chrome doesn't understand my two files quoted and separated by space.
UnknownError: unknown error: path is not absolute: "E:\MyProjects\tns\test\filesToUpload\testxls.xls"
"E:\MyProjects\tns\test\filesToUpload\testxlsx.xlsx"
Tried with both relative and absolute paths - the picture is the same, everything is OK in IE, the test fails in chrome
Who came across, tell me, pliz!

Answer 1

The option is purely on the ball, but did you try to slash in the other direction or escape in the paths?

Answer 2

In the wilds of the Internet, I found a solution
for Chrome files should be separated '\n'
But unlike IE, file names should not be wrapped in quotes

if (browser.browserName === 'chrome') {
            resultPath = absolutePaths.join('\n');
        }
      
  if (browser.browserName === 'internet explorer') {
            var newAbsolutePaths = [];
            absolutePaths.forEach(function (path) {
                newAbsolutePaths.push('"' + path + '"');
            });
            resultPath = newAbsolutePaths.join(' ');
        }
