According to a report, app crashes cause 71% of uninstalls. Other reasons that compel users to uninstall the app are page response time, confusing UI, battery consumption, etc. This indicates the importance of functional testing as well as non-functional testing to deliver a user-friendly app. So let’s understand what is functional testing.

Scott Jehl: One of the most impactful things we can do to improve page performance and resilience is to load CSS in a way that does not delay page rendering. That’s because by default, browsers will load external CSS synchronously—halting all page rendering while the CSS is downloaded and parsed—both of which incur potential delays. <link rel="stylesheet" href="/path/to/my.css" media="print" onload="this.media='all'"> Don't just up and do this to all your stylesheets though, otherwise, y

There are tons of tools out there that help you make sure your app is functioning correctly. But how do test software from a purely visual standpoint? Chances are you’re writing functional tests to check visual elements, or manually checking your UI whenever you push a change. If you are doing either of those things, then you know that they’re incredibly time-consuming and bugs still end up slipping through the cracks.

SQL Performance

I have been making the same recommendations about tempdb since I started working with SQL Server over 15 years ago, when I was working with customers running version 2000. The gist of it: create multiple data files that are sized the same, with the same auto-growth settings, enable trace flag 1118 (and maybe 1117), and reduce your tempdb use. From the customer side, this has been the limit of what can be done*, until SQL Server 2019.

In previous posts we have introduced the multiprocessing module which makes it possible to parallelize Python programs on shared memory systems. The limitation of the multiprocessing module is that it does not support parallelization over multiple compute nodes (i.e. on distributed memory systems). To overcome this limitation and enable cross-node parallelization, we can use MPI for Python , that is, the mpi4py module.

In today's world, data is generated in high volumes and to make something out of it, extracted data is needed to be transformed, stored, maintained, governed and analyzed. These processes are only possible with a distributed architecture and parallel processing mechanisms that Big Data tools are based on. One of the top trending open-source data storage that responds to most of the use cases is Elasticsearch.

Many years ago, I worked with a company that helped big pharma companies distribute free medical samples to doctors. Having pharma products on-hand is a convenience for doctors and patients alike, mainly because a doctor can initiate immediate treatment for a patient. Having pharma products on-hand is also good for big pharma, as starting somebody on a medication is highly likely to lead to a prescription.

If you have ever done it, it is quite apparent that Blazemeter and other similar services are pretty popular to help you with load generators and remote execution; however, I am not going to write about non-functional testing and services. I am going to write about a couple of articles, videos, and tutorials I have come across during this research.

In this phase, virtual user scripts are run based on the number of concurrent users and workload specified in the non-functional test plan.

What is Load Balancing? Load balancing refers to the distribution of a workload across several nodes. In the web hosting service industry, it is commonly used for balancing the HTTP traffic across multiple servers which act together as a web front-end. A Load Balancer allows the users to distribute the traffic to a single IP across several servers by using a set of different protocols.
