AMA: IE11 Button Clicking in Selenium

Anthony asks…

I have coded to click buttons on IE11/Win7 but the latest version of Selenium IE doesn’t click the buttons correctly most of times. Most of times, it clicks one button below. I thought it might be loading time so added some waiting but still click one button below or two buttons below sometimes. I googled this and found several posting saying Selenium IE doesn’t click buttons well. Now I have moved it to FF but I am still wondering why IE is not accurate. I know a lot of Selenium test developers in the field but they are having the same issue or they know a workaround. What do you think of this issue on IE11? Are you aware of this issue? FYI, the buttons are not regular HTML tag. The menu system with clickable tag is created by javascript. Thank you!

My Response…

We actually don’t run any tests in Internet Explorer any more since these weren’t finding any browser specific bugs (we do exploratory testing in Internet Explorer instead).

But, I have heard of problems generally with the IEDriver tool. If you’re working on a JavaScript generated app I think the best thing for you to do would instead of using a native click in Selenium is instead execute a JavaScript click event. The exact syntax will depend on which language you’re using Selenium in, but it should look something like this:

this.driver.executeScript( 'return arguments[0].click();', webElement );

I hope this solution helps!

AMA: CodeceptJS support for Safari and IE?

Sahana Asks…

We area VOD startup and we have web app, mobile apps and TV apps. I am writing acceptance tests for web app now and chose codeceptjs framework since we have our website’s front end code in Javascript. We have dockerised the processes and docker images for codeceptjs webdriver IO is availble only for chrome and firefox browsers. How can I handle Safari , Internet Explorer browsers ? Looks like CodeceptJs does not support IE and Safari browsers. Do you have any suggestion?

My Response…

I’ve never personally found the return on investment of getting automated tests running across Internet Explorer and  Safari to be worthwhile as in my experience this took more effort than the bugs it found. So I personally stick to running our full e2e test suite in our most used browser (Chrome) and supplementing this with exploratory testing on all other browsers.

In saying that the reason you won’t be able to use Docker containers for these purposes is that they’re Linux and Internet Explorer requires Microsoft Windows and Safari requires Apple macOS to be able to run. To be able to use these for your existing automated tests you can sign up to a on-demand browser service like SauceLabs and use the remote WebDriver protocol to execute your tests.

AMA: What sets exceptional QA testers apart?

Dayana asks…

I wondered if you could tell me what sets exceptional QA testers apart? Not just personality or work ethic traits, but specific skills and programming knowledge that will be very valuable to a team?

My response…

I think exceptional QA testers, as explained recently, aren’t people who are exceptional at just one thing, eg. testing, but good at lots of things.

So an exceptional QA tester, in my opinion, will typically have (at least good) skills in the following things:

  1. Skills in human exploratory testing: an exceptional QA tester has the ability to effectively find the most important bugs fast. Whilst this skill can be developed, I have found it’s mostly a mindset.
  2. Skills in developing automated tests: an exceptional QA tester will have programming skills needed to develop automated tests and I would recommend these to typically match the programming language(s) that programmers in your organization use. For example, skills in automated testing in .NET if your company primarily uses Microsoft .NET. Although, someone with strong programming skills in one language (eg. ruby) should be able to transfer these skills to another language (eg. python).
  3. Knowledge/Experience in your business domain: an exceptional QA tester will fully understand your business domain and keep this context in mind whilst testing a product and raising issues. An exceptional tester is always testing your system – just as I am testing WordPress.com publishing this post.
  4. An empathetic mindset: we design and develop software for real people and real life. An exceptional QA tester will test with this in mind.

AMA: Test Data Infrastructure

Anonymous asks…

Do you have set up (inexpensive) infrastructure to store data collected in your automated tests? We are currently using using selenium Java webdriver to automate our tests and IntelliJ as our IDE. We create data from scratch for each and every test case :(

My response…

I’m a little confused by the question and whether it’s about test data: data is that is needed by the automated tests, or test results data: insights into the results of our automated tests. So I’ll answer both 😀

Infrastructure to manage test data

Our tests run on specific test accounts and sites on production databases. Since our tests are end-to-end in fashion, we try to make our tests have as few dependencies as possible on existing data. Often an end-to-end scenario will involve creating, viewing, editing and deleting something. If we don’t do all of this by our UI we can use hooks that either use services or database jobs to clean up the data. I explained this in more detail previously.

Infrastructure to manage test results data

We use CircleCI for automated end-to-end tests. We have a number of projects that run different types of end-to-end tests from the same code repository for different purposes (canary tests, visual-diff tests, full regression tests for example).

We generate x-unit test results (from Mocha/Magellan) which CircleCI uses to provide insights into our test results such as this:

You can also drill down into slowest tests and most failed tests etc.

Since all our tests are open source you can view these build insights yourself!

We’re pretty happy with the insights we get from CircleCI at the moment so we don’t see a need to currently develop anything ourself.

AMA: Testing an Angular app

Ben asks…

I’ve been working with angular a while now but I have to admit, the testing side throws me. Every time I start to tackle it, I find myself distracted from the test I want to write by all of the things I need to mock. Sometimes it feels like I need to build an entire mock framework to test one feature. Maybe I’m doing it wrong. Any tips appreciated, whether practical or even just the right headspace for approaching it :)

My response…

I haven’t worked with angular applications directly but I’ve worked on React applications and I’m guessing the approach to unit testing these will be similar.

I would start as simple as possible with the smallest test that would possibly work. If you find that you need an entire mock framework to test a feature it sounds like your components may need to be broken down further into smaller components as you have too many dependencies that need to be mocked. If you have smaller components that only require a single dependency then these components should be easier to test as the dependencies will be easier to mock.

With smaller components I would also encourage you to be able to pass in dependencies. This allows you to easily mock/override dependencies for testing purposes – known as dependency injection. I wrote about this using a simple JavaScript example previously which you may want to read.

If retrofitting unit tests into your app is still too difficult you could try to automated some key end-to-end scenarios using Protractor, but I’d discourage you from going overboard since these can quickly get out of hand. You may still benefit from having a few of these tests even if you get unit testing of small components working well to ensure the small components work well together.

I hope this helps you Ben 😊

Save password prompts in Chrome 57 with WebDriver

When running Selenium WebDriver scripts against the latest version of Chrome (57) it shows a save password prompt that hasn’t appeared previously whilst using Chromedriver, as far as I know.
