Introduction. In today’s highly competitive world, software development and automation play a significant role in creating robust software applications for businesses. Additionally, emerging technologies like artificial intelligence and blockchain have given a competitive edge to enterprises. For gaining maximum benefits out of automation testing , testers require hands-on experience in a minimum of one automation programming language.

By Alok Tiagi , Hariharan Ananthakrishnan , Ivan Porto Carrero and Keerti Lakshminarayan Netflix has developed a network observability sidecar called Flow Exporter that uses eBPF tracepoints to capture TCP flows at near real time. At much less than 1% of CPU and memory on the instance, this highly performant sidecar provides flow data at scale for network insight.

If you have a public-facing web application, the odds are you should probably be thinking about load testing. Any tester can (and should) add load testing to their repertoire. Functional tests are often carried out with a single user’s experience of your application in mind, but what happens when hundreds or thousands of users are on your site at the same time?

I’m weary of always comparing the web to so-called “native” platforms like Android and iOS. The web is streaming, meaning it has none of the resources locally available when you open an app for the first time. This is such a fundamental difference, that many architectural choices from native platforms don’t easily apply to the web — if at all.

Web tables, or "data tables," are a common sight in many web-based applications. These tables are predominantly used for displaying information in a tabular format. Rows and columns are the key identifiers of web tables in Selenium. If you’re using tables in Selenium PHP, you can perform several operations on the table, like fetching data from a specific row-column combination, searching for a particular key string in the table, etc.
