Falling beneath the umbrella of performance testing, both load and stress
testing play an important role in assessing the availability and performance
of your web or mobile applications under expected and extreme load.
While the terms "stress testing" and "load testing" may be used
interchangeably within a testing team or organization, the two differ when it
comes to their definitions and purpose.
Stress Testing vs. Load Testing
Load Testing: A performance-related testing process that places simulated
demand on software, web or mobile applications in order to measure responses
and systems' behavior under both normal and anticipated peak load conditions.
Its purpose: Providing insight into your application and system's behavior
under expected load conditions.
Stress Testing: A testing process designed to push an application's
environment to its breaking point so that Q... (more)
Ah, the plight of software testers - destined to crank away behind the scenes
ensuring all runs smoothly. Unlike musical conductors who command the
spotlight while overseeing the performance of a piece, testers only seem to
attract attention when things go terribly wrong.
The same can be said for most IT professionals, at least according to Reddit.
In December, this question was posed to the AskReddit community:
"What is a job when done right no one notices, but the moment its [sic] done
wrong all eyes are on you?"
Second only to a response about bass players, a comment citing IT ... (more)
If you read the title and assumed this post would be filled with baseball
analogies, you'd be right! It's game day and all those fans who fill up major
league stadiums, those are your application users. They are invested in the
game and have shown up to watch the players (i.e. your application) perform.
Depending on how the game plays out, your audience will either head home
elated or full of disappointment. The great thing is that in your case,
unlike in the case of traditional baseball games, there doesn't have to be a
loser. You can consistently ensure happy mobile users by set... (more)
The cloud provides two major advantages to load and performance procedures
that help testing teams better model realistic behavior: instant
infrastructure and geographic location. Cloud-based load testing also lowers
the total cost of ownership, increases flexibility and allows testers to
understand the impact of third-party components. So you're sold on using the
cloud; here's what you should look for in a cloud-based load testing
One of the most dangerous moves software developers and testers can make is
being lulled into a false sense of security. For example, when ... (more)
Providing a full-duplex communication channel over a single TCP connection,
WebSocket is the most efficient protocol for real-time responses over the
web. If you're utilizing WebSocket technology, performance testing will boil
down to simulating the bi-directional nature of your application.
Introduced with HTML5, the WebSocket protocol allows for more interaction
between a browser and website, facilitating real-time applications and live
content. WebSocket technology creates a persistent connection between the
client and server, circumventing the requirement for a client-initiate... (more)
