Poorly performing websites, like Twitter's recent fiasco with Ellen's selfie,
are a constant source of irritation for users. At first you think it's your
computer, or maybe someone on your block is downloading the entire "Game of
Thrones" series. But, when nothing changes after refreshing the page once or
twice, you give up, mutter under your breath, and move on.
Whatever the reason for a website crashing or slowing down, it's bad for
business and for your online reputation. According to a survey conducted by
Consumer Affairs, a dissatisfied customer will tell between 9-15 people about

Understanding how your website performs under pressure is extremely important
for any company. But, it can be daunting trying to figure out w... (more)
The selfie that changed the world, or at least Twitter, has been in the news
for the past month. On March 2, 2014, the infamous Oscar selfie of Ellen and

Agile software development isn't really a "new" trend anymore. I mean, the
Agile Manifesto turns 13 years old next month and while that might be early
adolescence in human years, it's downright ancient as far as trends in IT are
concerned. However, one area that has yet to fully mature is the
implementation of non-functional testing practices in a Continuous Testing
sort of way that can keep pace with more Agile development teams. Load and
performance testing definitely fall into that category. You might be a
performance tester on a team that is just starting to do more iterative... (more)
October 1, 2013, was the most anticipated date for the Obama administration
since his re-election. It was to be the day every American would have access
to health care on one centralized website. However, according to at least one
report only six people enrolled in Obamacare on the first day. Then shortly
after, the entire website crashed along with its infrastructure.
The massive crash happened because within the first 10 days of launch
HealthCare.gov had over 14.6 million unique views. Something the Obama
administration was not prepared for, nor the testers.

As a tester, you understand how important it is to create the most realistic
