Top 5 JUnit and Unit Testing Courses for Java Programmers

DZone

java performance testing tdd unit testing junit online courses mockito unit tests java for beginnersToday, we're going to talk about JUnit and unit testing, one of the key skills for any software developer. You may already know that JUnit and Mockito are two of the most popular testing libraries for Java applications, and you will find them in almost every Java application classpath. I often meet and work with Java developers who know Java well but haven't written a single unit test.

Effective Concurrency Course: June and (Not) October

Sutter's Mill

I forgot to blog about this until now because of focusing on the Effective Concurrency course in Stockholm a few weeks ago, but to answer those who wonder if I’ll be giving it again in North America too: Yes, I’m also giving the public Effective Concurrency course again at the end of this month at the Construx facility in Bellevue, WA, USA. This will be the full four-day version of the course.

The Performance Inequality Gap, 2021

Alex Russell

Not as much as we'd like, of course, but the worldwide baseline has changed enormously. There are differences, of course, but not where it counts. Of course, if most of this content is JavaScript, it must be compiled and run, shrinking our content window back down significantly.

Faster remainders when the divisor is a constant: beating compilers and libdivide

Daniel Lemire

Of course, if d is not a power of two, 2 N / d cannot be represented as an integer. Not all instructions on modern processors cost the same. Additions and subtractions are cheaper than multiplications which are themselves cheaper than divisions. For this reason, compilers frequently replace division instructions by multiplications. Roughly speaking, it works in this manner. Suppose that you want to divide a variable n by a constant d. You have that n/d = n * (2 N / d ) / (2 N ).

10 Portfolio Projects for Aspiring Automation Engineers

One way to gain experience is, of course, to study and practice on your own. Those looking to break into the test automation field have difficulty doing so because of a lack of experience. But how do you demonstrate your newfound knowledge to employers? Other professionals, such as front-end developers, create portfolios to highlight their skills, and you can do the same as automation engineers!

Of course, if they do have to throw it out, then that speculative work accomplishes nothing. The other day I was auditing a site and ran into a pattern that I’ve seen with a few different clients now.

The Cost of Javascript Frameworks

Tim Kadlec

But of course, that’s just one part of the equation. There is no faster (pun intended) way to slow down a site than to use a bunch of JavaScript. The thing about JavaScript is you end up paying a performance tax no less than four times: The cost of downloading the file on the network.

The Future of Performance Testing

Alex Podelko

Of course, more sophisticated tools may definitely do better job in creating a simple and intuitive interface (still providing a way to invoke more sophisticated functionality when needed). And, of course, need for performance / cost modeling – to see how any change (for example, on a component level) will impact bottom line. Following up my post Are Times still Good for Load Testing? , I decided to answer multiple comments here separately.

Alex Podelko

Of course, it doesn’t mean that JMeter became the best tool for every task, but its popularity, in addition to being an open source tool, definitely gets it high in the list of options to consider. My post Good Times for Load Testing was published in 2014. It is difficult to believe that 5 years passed… Are times still good for load testing? Well, yes and no. I am not so upbeat as I was in 2014.

The Three Types of Performance Testing

CSS Wizardry

The short answers are, of course ‘all the time’ and ‘everyone’, but this mutual disownership is a common reason why performance often gets overlooked. Of course, it is impossible to fix (or even find) every performance issue during the development phase. A lot of companies—even if they are aware that performance is key to their business—are often unsure of how, when, or where performance testing sits within their development lifecycle.

Industry Trends and Performance

That, of course, should involve more automation to performance checks. One software vendor ask me, along with a few other performance professionals, to answer questions related to performance trends.

Load Testing Your Application Using JMeter, Docker, and Amazon Web Services

DZone

Of course, you’re not in the business of making web applications that will only be used by just one person. Test how your application will react when many users access it. When building your application, you probably test your application in a lot of ways, such as unit testing or simply just running the application and checking if it does remotely what you expect it to do. If this succeeds you are happy. Hooray for you, it works for one person!

Master Apache JMeter. From Load Testing to DevOps

Alex Podelko

Of course, it doesn’t mean that JMeter became the best tool for every task, but its popularity, in addition to being an open source tool, definitely gets it high in the list of options to consider. But load tests considerably reduce the risk if they are carried out correctly (and, of course, can be completely useless and misleading if they are not). And, of course, a reproducible workload greatly simplifies debugging and checking multi-user problems.

The Broken Promise of Test Automation: Why Are We Still Hand-Cranking Tests?

DZone

Of course, those vendors really meant test execution automation. Remember when test automation was being peddled as a silver bullet for testing bugbears? Automating test execution was going to increase coverage, minimize testing time, and overall reduce the amount of money being spent on testing. It would even butter your toast in the morning. Well, those days are long gone. Organizations have now reckoned with implementing test automation and have grown wise to their challenges.
