There is an exponentially increasing cost associated with finding software defects later in the development lifecycle. In data warehousing, this is compounded because of the additional business costs of using incorrect data to make critical business decisions. Given the importance of early detection of software defects, let’s first review some general goals of testing an [...]

“Automated Testing” means automating the manual testing process currently in use. This requires that a formalized “manual testing process” currently exists in the company or organization. Minimally, such a process includes:
– Detailed test cases, including predictable “expected results”, which have been developed from Business Functional Specifications and Design documentation.
– A [...]
Performance counters are used to monitor system components such as processors, memory, network and the I/O devices. Performance counters are organized and grouped into performance counter categories. For instance the processor category contains all counters related to the operation of the processor such as the processor time, idle time, interrupt time and henceforth. If [...]
This article lists the common problems & solutions that performance engineers come across when testing flex applications.
Problem #1 : Overlapped transmission error occurs when a flex script is run for the first time from controller. But the same script works fine in VuGen.
Error -27740: Overlapped transmission of request to “www.url.com” for URL “http://www.url.com/ProdApp/” failed: WSA_IO_PENDING.
Performance testers are confronted with this classic dilemma when they decide to execute their script in LoadRunner. Whether to run the Vuser as a thread or as a process?
1.1 Difference between a thread and a process
Let us consider a process as an independent entity or unit that has an exclusive virtual [...]
In global everyone thinks that OpenSTA is compatible with only Internet Explorer & Netscape Navigator browsers to record a script. Through this article you will come to know how to record a script in OpenSTA using Mozilla Firefox.
In my project we had a scenario which was not compatible with IE browser but we were supposed [...]
In this IT market, we have “N” no of tools w.r.t Commercial tools (Loadrunner, Rational Performance Tester…) and Open Source tools (Grinder, OpenSTA…) to measure the performance and scalability of the Web based and desktop based applications. Also it is an open area for performance Test Engineer/Test Consultant to choose an appropriate performance testing tool [...]
Performance testing in production is not practiced widely owing to many risks involved, which include taking the entire production environment offline thus affecting availability, taking part of the production environment offline thus affecting performance, and the risk of updating production data during the test.
However, for applications running on large infrastructure for which there are no [...]
How to Simulate the Load from Safari Browser
There was an interesting requirement where we had to simulate Safari browser at the time of load execution.This article provides information on how to achieve this.
Recently we were involved in a PoC to check the feasibility of SalesForce.com with LoadRunner.
There was one [...]
