E2E testing on angularjs using protractor yielding different results between running a single test file and all test files

Question

I am using protractor to do E2E testing on an angularjs application. I started with the angular-seed base project which comes with npm set up to run all of your e2e tests with the command npm run protractor, which really just runs "protractor test/protractor-conf.js". I have a test that goes to a page, selects a dropdown menu item, and then verifies that the resulting

it('should render all of the available '+subsystem.subsystem_name+' that can be created', function() {

// first select the appropriate subsystem from the dropdown

                element(by.cssContainingText('.subsystem_select option', subsystem.subsystem_name)).click().then(function(){
                    var create_table = element.all(by.css('table')).get(0);
//                  filter the General Options and check that the Option Create Table is rendered correctly
                    browser.executeScript(function(ms_valid_options,subsystem_id) {
                        return angular.element(document).injector().get("$filter")("filter")(ms_valid_options, {subsystem_id:subsystem_id})
                    }, MS_VALID_OPTIONS, subsystem.subsystem_id).then(function(filtered_options){
                        expect( element.all(by.repeater('option in valid_options')).count() ).toEqual(filtered_options.length);
                        filtered_options.forEach(function(valid_option,i){
                            var current_row = element.all(by.repeater('option in valid_options')).get(i);
                            expect( current_row.all(by.css('td')).get(0).getText() ).toEqual(valid_option.option_name+"("+valid_option.default_value+")"); //first table cell has text option_name(default_value)
                            expect( current_row.all(by.css('td')).get(1).getInnerHtml() ).toEqual('<input type="button" value="Add Option" ng-click="addOption(option)">')//second table cell contains the add option button
                            expect( current_row.all(by.css('td')).get(2).all(by.css('span')).get(0).getText() ).toEqual('?');//third table cell contains the help questionmark
                        });
                    });
                });
            });

when I run the individual test file all the tests pass as expected, but when I run all of the test files with the npm run protractor command, this test is failing with the error

TypeError: Object [object Object] has no method 'all' and this error is complaining about the line

expect( current_row.all(by.css('td')).get(0).getText() ).toEqual(valid_option.option_name+"("+valid_option.default_value+")");

Any insight into this issue would be appreciated

Thanks

edit just a bit more information, when running the single file(successful case) current_row is an object with these keys on it [ 'locator_', 'parentElementFinder_', 'opt_actionResult_', 'opt_index_', 'click', 'sendKeys', 'getTagName', 'getCssValue', 'getAttribute', 'getText', 'getSize', 'getLocation', 'isEnabled', 'isSelected', 'submit', 'clear', 'isDisplayed', 'getOuterHtml', 'getInnerHtml', 'toWireValue' ]

and when the test is run along with all the other tests(failure case) current_row is an object with these keys on it [ 'then', 'cancel', 'isPending', 'errback', 'driver_', 'id_', 'click', 'sendKeys', 'getTagName', 'getCssValue', 'getAttribute', 'getText', 'getSize', 'getLocation', 'isEnabled', 'isSelected', 'submit', 'clear', 'isDisplayed', 'getOuterHtml', 'getInnerHtml', 'toWireValue', '$', 'findElement', '$$', 'findElements', 'isElementPresent', 'evaluate' ]

Answer 1

I have had issues with tests interfering with one another, which may be the case here. I basically just had to make sure I was in the correct state after each of my tests by doing logouts in an afterEach(), and starting from login for each test, or related set of tests.

Answer 2

First of all I would make use of a PageObject (po) to make the tests more readable. So for example you could include initially:

var poSubsystem = {}, option1Text='..';
poSubsystem.table = element(by.tagName('table')).first();
poSubsystem.options = poSubsystem.table.all(by.tagName('td'));
poSubsystem.option1 = poSubsystem.options.first();
// .etc
expect(poSubsystem.option1.getText()).toEqual(option1Text);

By the time you've tidied things up the answer should have made itself known :-)
