Software Testing Improving Electrical Hardware Designs

When we think of performance testing and calculations, it is typically with regard to the performance of a given web application or software. We use performance testing processes to “validate the performance of an application under load”, and thereby determine what if any changes need to be made to optimise that performance and improve results. It’s an…

JMeter – Passing Variable Value to another Thread Group

Under a Test Plan, you can add multiple Thread Groups. But these Thread Groups are independent of each other. The child elements of these Thread Groups have limited scope and do not share any information outside the Thread Group scope. Sometime in JMeter, there is a requirement of passing the value of the variable from…

Regular Expression (RegEx) – Easy to learn

Regular Expression (RegEx) is a sequence of characters that define a search pattern. Each character in a regular expression is understood to be a metacharacter (with its special meaning), or a regular character (with its literal meaning). For example, if we define a regular expression r. where ‘r’ is a literal character which matches just ‘r’ and ‘.’ is…

How does JMeter simulate a real browser?

Just to have a knowledge of how to record the script for an application and execute the test; should not be enough for a performance tester. As described in the previous article, performance testing should be realistic rather than just a simple test. To implement this concept, a performance tester should know how does a…

How to make a Performance Test more realistic?

Performance Testing of any application or system has two primary objectives: To find out the capacity of the system at the desired load To find out the performance bottleneck which restricts the system to achieve the expected load. On the basis of these two main goals, performance testing tools are designed. One point to be…

Now a day, it is straightforward to check the response time of any website from different geographical locations. For a company, it’s important to determine their website’s or system’s performance on a regular basis. The better performance of the website of any organization increases the ranking in the search engines like Google and faster pages…
