An Online Test Competition

When the staff at NRGGlobal asked me to start blogging for them, they asked what we had in common, and what they could do for the test community.

The Moment We've Been Waiting For

It’s here!  It’s here!  If you are reading this, then the Test Competition is finally here!

Tuning Performance with Method-R

I've been that guy. You may be that person some day ... you may be that person now. Either way, it is safe to sat that those in that position would prefer to be out of it.

The Black Swan In The Enterprise

Amazon’s Service level agreement for it’s cloud computer service is 99.95% uptime for a service region (that’s a data center) during a one year period.

Understanding the difference between total users and concurrent users.

Many of our clients have enterprise applications that are accessed 24 hours a day, seven days a week.  Their applications may be accessed remotely from all over the world.  In such cases, total users could number in the thousands.

Oracle Apps Tutorial: How to Automate Oracle EBS Patch Testing

Steve Sutphin, an Oracle expert for over 20 years, had this to say about using AppLoader for regression testing.

A Tale of Two Performance Projects

Imagine for a moment two companies have an identical problem - the website is slow.  Perhaps this is a huge problem; the company bet it's future on a new product, that customers sign up for on the web, and performance is bad enough that people are abandoning the site and going to the competition.[…]

Testing Cloud Applications: Cloud Load Testing vs. Traditional Load Testing

 

Deviant Deviation

A few years ago, I worked a performance project.  You probably know the type:  Customers were upset, executives were upset, technical staff were asking for specific direction (and not getting much) ... nobody was happy. The code was already in production, and there was no obvious ‘roll it back to[…]

Testing the Upgrade from Eclipsys 5.0 to Eclipsys 5.5:

If you are starting or thinking of starting your Eclipsys 5.5 upgrade, you are probably wondering what approach to take when testing the upgrade and what issues others have uncovered during testing.

Test Competition Update

It has been two weeks since we announced the details and how to register for the NRGGlobal test competition.  Since that time, we've had three teams register.

Serious Web Load Testing

It is called the basketball exercise, or sometimes inattention blindness, and it demonstrates a real problem in many kinds of automated testing.

Yugo Testing

Recently, I was invited to observe a colleague’s monthly stress test exercise. There is a large room filled with mangers and technicians, experts in various aspects of the system, general network specialists, application specialists, customer support representatives and a collection of people with[…]

5 Reasons to Consider an Image Recognition Testing Tool

There's an ongoing debate in the applications development world on whether front end or back end testing is the most effective method. However, the discussion shouldn't be just about where the testing takes place, but rather about the ease of use and effectiveness of the tool. Traditional testing[…]

Another Way to Monitor Performance

A few years ago, one of the companies I worked with created a "Production Application Support Team", or PAST.  These were the sysadmins and programmers intended as the next line of support after the helpdesk, who could triage some problems and perhaps actually fix them.

Performance Matters

By Matthew Heusser Hello; I am Matt Heusser, a risk management consultant and sometimes writer.  You can learn more about me at xndev.com. The folks at NRG Global have asked me to start blogging for them because their place in the community aligns with mine.  We are both interested in minimizing[…]

Method R Meets Profiling

If you've been following me talk about Method-R, you might wonder how I learned it.  In my case, I learned it the "right way", the "official way":  My employer brought in a consultant to teach a three-day class in performance tuning.  Method-R was the method he taught.

Update: One Month To Test Competition!

On March 11th, 2013, registration for the test competition closed.

(Just Starting to) Analyze Performance Data

If you've done any performance testing, or even seen a demo, you are probably familiar with the “big line graph” that is created as the test runs. A Typical Response Time Graph The typical scenario is simple:  Have the load tool start with one simultaneous user running a script.  Then add a new[…]

More On The Test Competition

Over the past two weeks I have spent a great deal of time doing research, gathering resources, and judging interest in an on-line test competition in software testing.  My conclusion is kind of like Nike.

Testing web applications across different browsers and operating systems.

You have a client server application used through the web and another used through a fat client. Every month you need to install required automatic updates on different Windows Operating Systems and some application patches. Your users use the application on different Operating Systems and use[…]

More On Power

One of our contributors, Pete Walen, recently put out a blog post on leadership and power.  It is a good post; if you enjoy reading long-form articles that are more conversation than bullet-points, I suspect you'll get a kick out of it.

10 Steps to load test a business application

1. Test from the end user's perspective

The Killer App

We called it the Killer App, and, for the insurance industry, it was magic.

The Consultant's Gambit

The class where I learned method-R performance tuning also taught me something else, something I call the consultant's gambit. This is that story.

On Power

Every week on "The Apprentice" may be different, but we know one thing:  Donald Trump is going to walk in, ask questions, fire someone, and drive on.

The Next Killer App

Today I’ll cover the story of project number two, "just a little code" to integrate two systems.  But first, let’s talk about my motivations. 

The Killer App Finale

Last week I posted The Killer App, the story of a real software project with a cliff-hanger, pick-a-path ending.  It's time to close the loop.

System Shenanigans

Last week I put out the Black Swan In The Enterprise, which argued that most uptime planning comes from the ability to predict the future -- and sometimes, the future is wildly different that you would have predicted.  Things fall apart; the centre does not hold -- and they fall apart very[…]
