How do I tackle machine learning in software testing?

Image result for How do I tackle machine learning in software testing?Welcome to the world of machine learning in software testing. Machine-learning software takes past data and uses that data to better understand and make decisions in a problem domain. It consists of a series of mathematical algorithms that are able to adjust themselves based on its understanding of that data. It won’t produce an exact answer, but it will usually produce one that is close enough to correct for its problem domain.

This type of software usually uses a technology called neural networks, which, to put it in a simple way, mimics the operation of the human brain. There are other technologies, such as genetic algorithms and rules-based systems, but most deep-learning systems are using neural networks.

Machine learning in software testing requires an entirely different approach. You will rarely, if ever, get the same result twice with the same input. Testing these systems requires a deep understanding of the problem domain and the ability to quantify the results you need in that domain. Are your results “good enough?” You have to internalize that a bug is more than just an unexpected output.

For machine learning in software testing, you should also have a high-level understanding of the learning architecture. You don’t have to read the code, but you do have to be aware of the architecture of your network and how the algorithms interact with one another. You might have to tell the developers that they have to toss out their approach and start over again. Don’t let the highly mathematical nature scare you. Machine learning in software testing is accessible to all testers with an open mind.

The machine-learning revolution is just starting; if you haven’t encountered it by now, you likely will in the near future. With machine learning in software testing, you need to be comfortable with being able to measure and quantify your testing and objectively explain your confidence in the results.


Facebook’s Testing Out a New Tool to Help You Connect with Like-Minded Users

Facebook’s Testing Out a New Tool to Help You Connect with Like-Minded Users | Social Media Today

Facebook’s always looking to boost sharing and interaction on the platform – as The Social Network has noted previously:

Our top priority is keeping you connected to the people, places and things you want to be connected to — starting with the people you are friends with on Facebook.”

Not only does this encourage more engagement (which is a crucial measure for social platform success), but more sharing means more data, and more data means better ad targeting. Facebook needs to facilitate connection in order to fuel their whole business model.

Which is why their latest test makes sense.

According to TechCrunch, Facebook’s rolling out a new “Discover People” option which will enable users to connect with others who are interested in similar things as they are, including upcoming events, people who work at the same company or even those who simply live nearby. The new feature was initially tested in Australia and New Zealand but it’s now in the process of being rolled out more widely.

The new option will be available within the options menu (the three lines) – some users will have access already.

Once selected, you’re prompted to update your profile bio and photo to ensure it’s accurate and up to date. Below that, you’re shown a list of all the events for which you’ve registered an interest in attending – when you click into any of these, you’re shown a listing of other people who will be heading along, and you can click onto any profile for more information.

As you can see, clicking on a profile will show you not only who each attendee is, but also any things you have in common with them, helping facilitate connection.

And as noted, in addition to events, you can also see a listing of work colleagues and people who live in the same area, further adding to the connective capacity of the tool.

It’s an interesting option, and it certainly adds something to the Facebook mix – but is connecting with strangers something Facebook users will warm to?

In the case of events – particularly business related functions – the tool makes some sense, and LinkedIn actually offers similar in their new platform prompts, introduced as part of their recent redesign.

YouTube Testing New In-App Chat Function to Boost Social Activity

Image result for YouTube Testing New In-App Chat Function to Boost Social ActivityGoogle has never fared particularly well in social.

This was highlighted earlier in the week when the search giant announced a new update for Google+ – which reminded many that Google+ actually does still exist. Yet, despite their various attempts and failures in trying to tap into the social realm, that hasn’t stopped them from trying. I mean, really, they can’t – social platforms are continually cutting into their core business, with more and more discovery activity being conducted with social apps, a trend that only looks set to grow.

That same impetus appears to be behind their latest shot at social functionality, with Google-owned YouTube testing a new in-app messaging platform which enables users to share their thoughts and comments about YouTube content on YouTube – not somewhere else.

It’s pretty straight-forward – you watch a cool video on YouTube and you can immediately share it with your friends, so long as they also have the YouTube app installed. And of course, a lot of people do have the YouTube app on their devices – millions of iOS users have downloaded the app and it’s included on Android by default.

It makes sense, right? Now that it’s easier to share YouTube content directly, within the app itself, more people will do that than click on the Facebook or Twitter button and go share it over there. Right?

This is the same flawed approach Google has repeatedly taken in social, that if you give people an improved or streamlined experience, they’ll use that instead. But they won’t.

Why? Because their friends are on Facebook already. Adding a new chat experience means people need to re-align how they do things, where they share, how they get others involved. And most just won’t bother.

This is the same problem with Google’s new Allo messaging app – yes, it’s good looking and it has cool features like Google Assistant built in, but most people have already established their networks of friends on Messenger and WhatsApp. In order for them to switch to Allo, they’d need to convince all of those friends to also come across in order to make it worth their while, which ultimately means Allo likely won’t see any significant take-up, despite being an arguably more advanced and better messaging platform.

Google+ was the same – its systems may have been better, more advanced, but it offered no key differentiation from the existing options outside of that, which meant users felt no real compulsion to switch across. Everything they cared about was already on Facebook.

Of course, that’s not to say a new option can’t come in – Snapchat’s been able to take audience share from the established players by offering something users can’t get anywhere else, cool new features and tools that differentiate it from the pack and appeal to audiences looking for an alternative. But that differentiation is key.

So, yeah, YouTube might soon have a new messaging system, and it looks okay, functional. But I doubt you’ll see a big enough migration of users across to this option to make it a serious marketing consideration. Maybe, as you build up YouTube subscribers, you could use this to help spread the word. But then again, you’re probably better off using the other platforms where you have established connections and communities, as encouraging more action on those networks will produce greater return in increased reach.

If YouTube’s able to add something new to the process, some new messaging tools or features that make users want to check it out, the option could be something, but right now, in test phase, it looks like another Google social attempt that will be cool to know about, might even have some interesting quirks and benefits. But probably won’t become a major challenger in the space.
