Select option by value in Protractor fails

Question

I'm trying to select an option by option value. In this scenario, I have Categories and sub categories. Here is the application I'm testing using Protractor.

Here what I'm doing is first add the Category. and I have to refresh the page, because, only if I refresh the page, the added category will be listed in the category drop-down shown in subcategory tab. So, after refresh the page I click on subcategory tab and try to fill the fields in subcategory. But, my script fails when selecting the category from options.

Here are the two ways I tried.

Method 1:

// Select Category
element.all(by.model('sub_category.category_id')).each(function (eachElement, index)
{
    eachElement.click();
    browser.driver.sleep(500);
    element(by.css('.ng-not-empty > option:nth-child(10)')).click();
    browser.driver.sleep(500);
});

Method 2:

var select = element(by.model('sub_category.category_id'));
select.$('[value="Test Supplier Category by Me"]').click();
browser.driver.sleep(500);

Both methods gives an error called,

Failed: No element found using locator ...

Edit -

Here is the HTML

<select required="required" class="form-control empty ng-pristine ng-empty ng-invalid ng-invalid-required ng-touched" name="category_id" ng-model="sub_category.category_id" ng-options="category.id as category.category for category in categories_index" ng-required="true"><option selected="selected" value="?"></option><option value="string:6" label="Staff Cost">Staff Cost</option><option value="string:7" label="Utility Bill Expenses">Utility Bill Expenses</option><option value="string:8" label="Administrative Expenses">Administrative Expenses</option><option value="string:9" label="Building Rent">Building Rent</option><option value="string:10" label="Professional Charges &amp; Fees">Professional Charges &amp; Fees</option><option value="string:11" label="Vehicle Expenses">Vehicle Expenses</option><option value="string:13" label="Training &amp; Workshop Cost">Training &amp; Workshop Cost</option><option value="string:14" label="Marketing &amp; Promotional Expenses">Marketing &amp; Promotional Expenses</option><option value="string:15" label="Printing &amp; Supplies">Printing &amp; Supplies</option><option value="string:16" label="Fixed Assets">Fixed Assets</option><option value="string:17" label="Finance Cost">Finance Cost</option><option value="string:18" label="Statutory Payments">Statutory Payments</option><option value="string:19" label="Overseas Travelling Expenses">Overseas Travelling Expenses</option><option value="string:20" label="Test Supplier Category By Me">Overseas Travelling Expenses</option></select>

When I'm using Metod 1, following error occurs.

Could you provide the HTML representation of the `select` element(s) you are working with? Screenshots does not help much here. Also, post the complete traceback of the error. Thanks. — alecxe, Mar 15 '16 at 14:41

First of all, I don't see the Test Supplier Category by Me option in the posted HTML.

Also, it looks like you are checking the value attribute, but should be checking the text of the option instead. This could be done with an XPath locator:

element(by.xpath("//option[. = 'Utility Bill Expenses']")).click();

But, I would really look into using a Select wrapper proposed here:

Select -> option abstraction

Then, the code would be as simple as:

var SelectWrapper  = require('select-wrapper');
var mySelect = new SelectWrapper(by.model('sub_category.category_id'));

mySelect.selectByText('Utility Bill Expenses');

This gives an error called cannot find select-wrapper. :( – Manuli Mar 17 '16 at 04:13
@QualityProducts well, sure, because it is a separate `select-wrapper.js` file you need to manually create. Please carefully study the answer at that linked thread. Thanks. – alecxe Mar 17 '16 at 14:20
