The Power of AI in Application Performance Testing

Lub Rau Hli Ntuj 12, 2023 los ntawm Kev kawm Tester

Introduction: In the rapidly evolving landscape of software development, ensuring optimal application performance has become paramount. With the increasing complexity of applications and the need for seamless user experiences, traditional methods of performance testing often fall short. Tiam sis, the emergence of Artificial Intelligence (AI) has revolutionized the field of performance testing, offering unprecedented opportunities to identify bottlenecks, optimize performance, and enhance user satisfaction. This essay explores the remarkable benefits of leveraging AI in application performance testing using tools like Bard Chat and Chat GPT

  1. Enhanced Test Coverage: AI-based performance testing enables organizations to achieve superior test coverage by simulating real-world scenarios and user behavior. Traditional performance testing methods often struggle to accurately replicate complex usage patterns, leaving critical performance issues undetected until deployment. AI algorithms can analyze vast amounts of data, including user logs, historical performance data, and usage patterns, to create realistic and dynamic performance test scenarios. By mimicking real-world user interactions, AI-powered tests provide more comprehensive coverage, identifying potential bottlenecks and issues that may arise under varying conditions.
  2. Efficient Test Case Generation: AI algorithms can significantly streamline the test case generation process. Instead of manually designing test cases, AI can automatically generate an extensive set of test scenarios by considering various factors such as system complexity, user behavior, and anticipated load. This automation eliminates human bias and reduces the time and effort required to create test cases manually. By leveraging AI, organizations can accelerate their testing cycles, enabling faster time-to-market without compromising on application performance.
  3. Real-time Monitoring and Analysis: AI-driven performance testing facilitates real-time monitoring and analysis of critical performance metrics. With the ability to process vast amounts of data in real-time, AI algorithms can swiftly identify performance anomalies, bottlenecks, and degradation trends. By continuously monitoring performance metrics, AI can detect even subtle changes that may affect user experience. Organizations can proactively address performance issues, leading to improved stability, reduced downtime, and enhanced user satisfaction.
  4. Predictive Analytics: One of the most significant advantages of AI in performance testing is its ability to predict application performance under different load conditions. By analyzing historical performance data, AI algorithms can forecast how the application will perform when subjected to increased user traffic or system stress. This foresight allows organizations to make informed decisions about infrastructure scaling, resource allocation, and performance optimization strategies, mitigating risks before they impact end-users. Predictive analytics empowers businesses to optimize their application’s performance and deliver a seamless user experience, even during peak demand periods.
  5. Root Cause Analysis and Optimization: AI-based performance testing enables detailed root cause analysis by analyzing performance data, logs, and system metrics. When performance issues arise, AI algorithms can quickly identify the underlying causes, such as inefficient code, database queries, or infrastructure limitations. This information helps development teams pinpoint the specific areas that require optimization, allowing for targeted improvements. By continuously iterating and refining the application’s performance based on AI-driven insights, organizations can enhance application responsiveness, scalability, and overall user satisfaction.

Xaus: The utilization of AI in application performance testing has revolutionized the way organizations ensure optimal performance and user experience. Through enhanced test coverage, efficient test case generation, real-time monitoring and analysis, predictive analytics, and detailed root cause analysis, AI enables businesses to identify and address performance issues proactively. By leveraging AI-driven insights, organizations can optimize their applications, reduce downtime, enhance scalability, and deliver superior user experiences. As the field of AI continues to advance, the future holds even more promise for leveraging AI in application performance testing, allowing businesses to stay competitive in the ever-evolving digital landscape.

Zaj kwv huam ntawm Sh *** lub taub hau rau Recruiter

November 29, 2021 los ntawm Kev kawm Tester

I’ll illustrate the recruitment agency life cycle with a story: The Parable of Shithead.

Picture a wideboy from some Essex sink estate – all swagger and hairgel. Reptilian, devoid of all talent, a sociopathic disregard for others. Hungers for success, for fast cars and fit birds and gassy lager and awful nightclubs. He’s watched The Apprentice and finks he knows wot business is abaat. He’s got a shiny suit and practises his take-me-seriously-face in the mirror every day. His name could be Spencer or Kai, Nathan or Chardonnay, but I’m going to call him Shithead.

Shithead’s friend tells him about a job at his office. “It’s just like the telesales you’ve been doing since school. You just make these computer tossers take jobs they don’t want. The wages are crap and the boss is a bastard and you’ll get sacked if you miss the targets, but you make a packet on commission”. Shithead is bored with cold-calling people about comp-en-sation and this recruiting lark means he can get up later, so he takes the job.

Our protagonist rocks up for his first day at 24-7-Synergistic-Cyber-Resourcing-International Ltd. It’s a serviced office in Readingstoke, all plasticky and naff, full of berks like him who know nothing about IT. Presiding over this hive of villany is the company’s owner, Mr Bastard. “Old Bastard knows all the tricks” whispers the guy at the next desk, “learn from him and you’ll make a packet”. They give Shithead a crap PC, a phone, an account on LinkedIn and a database of IT professionals they scraped off a job site last week. After a few hours training he’s handed the spec for a terrible job they’ve been trying to fill for weeks and ordered to recruit his little heart out. “No pressure” they tell him, “but you’re sacked if you can’t find someone”.

All those funny IT words mean nothing to Shithead but he types a few into his database. He finds there are loads more matches if he leaves the “location” box blank. It spits out a list of all the experts in technologies like “L-U-N-I-X”, “Dogger” and “Curriculum Vitae”. Using some cool recruiter words the others taught him, he drafts an email. “L@@K! L.U.N.I.X ninja Dogger rockstar required for green-field migration project in London. Call for details!!!”.

He omits to mention that the role is a hundred miles outside London. On the seabed. In a burning submarine full of ebola and ravenous tigers. “Don’t want to discourage anyone” Shithead thinks.

At the click of a button he sends it to a thousand matches.

After half an hour no-one has responded. Worse, there’s a bounce message from some stuck-up arsehole saying he’s been blocked. He tries to argue with the bounce message, threatening to report it to the Internet Police for curtailing his Freedom of Expression. “We int doing nuffink wrong” Shithead mutters.

Disappointed that no-one appreciated his beautiful email he clears every search field, selects all 50,000 of the IT professionals in the database and clicks “send” again.

The responses start to trickle in. “Get lost you berk” scold the IT professionals, “quit wasting my time”. But Shithead has been trained for this and he pastes in some canned responses. “Wouldn’t you commute for such a great opportunity?” he wheedles. “I wudn’t be doing my job proper if I didn’t tell you about all these great opportunities”. “Yeah I know you said you wusn’t interested but don’tcher want to know about our £50 finder’s fee?”

A couple of people send CV’s but their acronyms don’t match the list on the spec so he bins them. “Fucking timewasters” he mutters, “we’re looking for a ninja rockstar domain expert in L.U.N.I.X, not this Ubuntu crap”. When the applications dry up he starts calling people from the database. “That’s nothing to do with my skillset” people keep saying. “I’ve told you guys five times I’m not looking for a contract”. He harangues them anyway until they put the phone down or cave in and mail him a CV.

Eventually some poor soul wins the game of acronym bingo. He pastes their CV into the company template, ruining the formatting and obscuring their identity just like Mr Bastard taught him. “Don’t want them arseholes going behind our back” Bastard reminds him.

After dithering for ten days the client asks for an interview. Unfortunately the applicant found a job somewhere else. “Don’t worry” Mr Bastard tells him, “just pick another one at random and send them”. The guy is hired and Shithead gets a small commission. He’s hit his target and won’t be fired this month. “I’m sure you’ll love it there” he chuckles down the phone, proud of how clever he is.

Mr Bastard calls Shithead into his office. “Well done young Shithead, we’ve been trying to fill that job for weeks. How did you do it?”. Shithead thinks of the thousands of people he spammed. “Yeah, well, I’m just real good at charming the talent”. Mr Bastard promotes him to the contract team. “That’s where the real money is” explains Old Bastard, “them contractors make a packet. Best thing is we don’t do any more work after we’ve found them but those dumbfuck clients have to pay us 15% of the daily rate forever!”

Six months later Shithead has learned everything about IT recruitment. He’s “placed” dozens of contractors and 247SCRI Ltd (they rebranded after that business with the dead guy and the tigers) is raking in two grand a day from the fruits of his labour. He’s rented a BMW and throws his money around in shit bars. He’s learned how to swindle the clients, to harvest CV’s by advertising fake jobs, to manipulate applicants, to pretend he’s “representing” someone who’s never heard of him and how to silence criticism of his dubious practices by asserting, improbably, “no-one else has a problem wiv it”.

He’s also learned how to roll some of his commission into a tube and with it, hoover the rest up his nose. Thus fortified Shithead lives in total certainty that he’s God’s gift to the IT industry. “I wuz doin’ you a favour” he tells people who catch him fraudulently using their CV, “and kiss my arse because you’ll never get a job in this town wivvout my ‘elp”.

But Shithead’s not a complete moron. He’s been earning a fortune for 247SCRI and Old Bastard keeps most of it for himself. He calculates what the guy must be making. “Cor!” Shithead thinks, “I could do that. It’ll cost nufink to start and if I go bust it’s them IT arseholes who lose out.”

A few hours later Shithead has nicked the database, registered a new company of his own (“Shithead-E-Web-Interglobal-Talent-Solutions”) and got some offshore web designers to build him a website. “Make it look really official” he tells them, so they fill it with stock photos of city skylines and people-looking-serious-in-the-workplace.

By Monday morning Shithead is working his way through the stolen client list. He knows what his old agency charged so undercutting them is easy. He also cold-calls the employers of former applicants to probe for jobs he can advertise, ruining a few careers in the process. “Ha” he thinks, “more jobs for me to fill”.

Six months later business is booming and Shithead’s feeling very proud of himself. He swaps the BMW for an Aston Martin, pays a dodgy accountant to cook the books and fills a serviced office with little shitheads of his own. They learn from a pro and the most avaricious quickly fly the nest to startagencies of their own. A million new agencies bloom.

 

For the Love of God End This Infestation

The UK tech industry is crawling with parasites like Shithead. We excuse their terrible behaviour by fancying it’s just isolated miscreants; that ones we’ve not caught red-handed must be squeaky clean. When my shitlist topped a hundred domains I came to realise tech recruitment is a wholly rotten industry. It’s a perfect storm of perverse incentives, low barriers to entry and minimal regulation with enough money sloshing round to attract a plague of unscrupulous middle-men.

I’m through with recruitment agencies. 90% of my work (and 100% of the work I liked) comes through word of mouth yet almost all my work-finding energy was wasted on these berks. Unless you’re starving (or enjoy being lied to and swindled) they’re not worth the endless weapons-grade aggrevation.

Their bullshit-filled emails go straight in the trash. The rest are pro-thick, so certain of their own brilliance that the instructions don’t apply.

To employers – ask your staff to help find new hires. Offer a bounty – enough to get their attention, say a fortnight’s salary. It’s a lot less than Shithead would cost. And their incentives are all positive: no-one will hire an idiot if they have to work alongside them and new staff with social ties to your team are far more likely to stay. You’ll be amazed how effective this can be.

To my fellow IT workers – don’t fall for the idea that recruiters are a necessary evil. Block their emails. Block their calls. Stay in touch with old colleagues. Learn to network. Join groups, boardsand mailing lists for your field and remember to post on them when trying to hire. Every time you fill a job through your social network a recruiter goes hungry. Remember, the more money you suck out of the recruitment ecosystem the fewer Shitheads it can support.

If you must deal with the agents, question everything they say. However nice they may seem remember they are not incentivised to act honestly. They’re not your friend. Get promises (and the job description) in writing. Check directly with clients whether the agent represents them. Before you’ve signed anything compare notes with the client to find out what the agent’s rate really is; often they’ll lie to you both to gouge out a larger cut. When you catch one behaving deceitfully publicise it so others will be wary. Reach out to the client (pro tip: go straight to HR) to tell them what’s going on. Odds are they’ll be appalled at how they’ve been represented. Have an expert read your contract (most recruiters are clueless about contract law) and question every onerous term. Walk away if they make excuses for not negotiating. If you’re a contractor and at the last moment they demand to see your ID (passport, driving license) refuse; they have no right to it.

Most importantly – have a backbone. When some sleazebag tries to get one over on you don’t let it slide. Don’t allow a swarm of rapacious middle-men to grow rich by ruining our industry.

Don’t feed the beast.

tosca testsuite
tosca testsuite

By adopting and implementing TOSCA an organisation will likely move upwards through the Test Maturity Levels.

Whilst it is important to recognise the significant advantages that Test Automation can bring to an organisation, it should not be considered to be a panacea which will solve all testing problems. However certain business intelligence softtware tools like Power BI are not always compatible with automated test tools.

In order to adopt test automation as part of the testing process (in addition to necessary manual effort) an organisation must recognise the following points:

  • The organisation must have a mature testing process and testing capability in place. Automation can only replace a current manual activity.
  • Automation requires significant investment in appropriate tools and the development and ongoing maintenance of automated test packs.
  • Automation is not suited to areas which are subject to volatile change.

Tricentis Tosca optimizes and accelerates end-to-end testing of your entire digital landscape. Its codeless, AI-powered approach accelerates innovation application testing.
