Being a square keeps you from going around in circles.

After a weary few hours sorting through, re-running and manually double checking the "automated test" results, the team decide they need to "run the tests again!", that's a problem to the team. Why? because they are too slow. The 'test' runs take too long and they won't have the results until tomorrow.

How does our team intend to fix the problem? ... make the tests run faster. Maybe use a new framework, get better hardware or some other cool trick.
The team get busy, update the test tools and soon find them selves in a similar position. Now of course they need to rewrite them in language X or using a new [A-Z]+DD methodology. I can't believe you are still using technology Z , Luddites!

Updating your tooling, and using a methodology appropriate to your context makes sense and should be factored into your workflow and estimates. But the above approach to solving the problem, starts with the wrong problem. As such, its not likely to find the right answers
.
The team are spending hours unpicking the test results. The results can't be trusted and need to be rerun or manually reviewed. They are the problems. Until you address the reliability, accuracy and precision of the automated checks they will always be a major source of failure demand

That dream of freeing up the team to move quicker or let the testers do more exploratory or security focused testing will remain a dream - while the team spend excessive time picking through the bones of your test results.

Your "automated tests" are a measuring tool. They help you measure the quality of your app. Imagine if your ruler reported a different length every 3rd time you used it! You'd blame the ruler and build or buy a better ruler. Rather than bemoan the time is takes to get an accurate measurement - while re-measuring objects to get "best of three!".

Try fixing or just disabling the flaky tests. Test your automated tests. Don't "create a failing test then see it pass" - investigate whether it was failing for the right reasons and then passing for the right reasons. Speak to your team mates e.g.: "How can I create Problem X realistically to check that my tests pick it up reliably?"

Do you hear these sort of conversations in your team? If so, then your team might need some coaching.

Betting in Testing

“I’ve completed my testing of this feature, and I think it's ready to ship” “Are you willing to bet on that?” No, Don't worry, I’m not going to list various ways you could test the feature better or things you might have forgotten. Instead, I recommend you to ask yourself that question next time you believe you are finished.  Why? It might cause you to analyse your belief more critically. We arrive at a decision usually by means of a mixture of emotion, convention and reason. Considering the question of whether the feature and the app are good enough as a bet is likely to make you use a more evidence-based approach. Testing is gambling with your time to find information about the app. Why do I think I am done here? Would I bet money/reputation on it? I have a checklist stuck to one of my screens, that I read and contemplate when I get to this point. When you have considered the options, you may decide to check some more things or ship the app

XSS and Open Redirect on Telegraph.co.uk Authentication pages

I recently found a couple of security issues with the Telegraph.co.uk website. The site contained an Open redirect as well as an XSS vulnerability. These issues were in the authentication section of the website, https://auth.telegraph.co.uk/ . The flaws could provide an easy means to phish customer details and passwords from unsuspecting users. I informed the telegraph's technical management, as part of a responsible disclosure process. The telegraph management forwarded the issue report and thanked me the same day. (12th May 2014) The fix went live between the 11th and 14th of July, 2 months after the issue was reported. The details: The code served via auth.telegraph.co.uk appeared to have 2 vulnerabilities, an open redirect and a reflected Cross Site Scripting (XSS) vulnerability. Both types of vulnerabilty are in the OWASP Top 10 and can be used to manipulate and phish users of a website. As well has potentially hijack a user's session. Compromised URLs, that exp

Test Engineers, counsel for... all of the above!

Sometimes people discuss test engineers and QA as if they were a sort of police force, patrolling the streets of code looking for offences and offenders. While I can see the parallels, the investigation, checking the veracity of claims and a belief that we are making things safer. The simile soon falls down. But testers are not on the other side of the problem, we work alongside core developers, we often write code and follow all the same procedures (pull requests, planning, requirements analysis etc) they do. We also have the same goals, the delivery of working software that fulfills the team’s/company's goals and avoids harm. "A few good men" a great courtroom drama, all about finding the truth. Software quality, whatever that means for you and your company is helped by Test Engineers. Test Engineers approach the problem from another vantage point. We are the lawyers (& their investigators) in the court-room, sifting the evidence, questioning the facts and viewing t
