What All You Need To Do For Software Performance Testing ?

Performance of the software is one aspect that cannot be overlooked or ignored even if it has functionality richness

. If the software performance is poor, it cannot address clients requirements. Product specifications laid out in the initial stage of development sometimes lead to architectural design flaws, which in turn pave way for poor software performance. Hence, its paramount to check for software performance before its released in to the market.

Software performance testing technique is used not to spot bugs, but to remove bottlenecks, if any and cement the platform for regression testing to be conducted in the future. Now as a tester, this question must have popped up in your mindWhere to start from?

Well, begin by identifying your clients business requirements and then classify them accordingly as end-user requirement, business requirement or technical requirement. If you spot the need as end-user requirement, you must estimate the application functionality, decipher performance needs and objectives, quantify those goals, record the performance results based on experiences, brief the recorded results and sign off. If its the case of a business requirement, transaction response time would be less than 3 seconds and must support around 10,000 end users under ideal conditions.

Now if the identified business need is a technical requirement, youd notice that CPU utilization rate is more than 80% lasting for a few seconds. This can be classified as a bug, which you can point out to your development team. Performance testing is challenging sometimes, especially in a scenario like this.

A tester must then draft a test plan, which should entail load testing strategy, test methodology, testing tools to be used, information about scripting, library development etc., resource allocation, risk management, test pass or fail criteria, test environment creation criteria etc. A tester must then go for load testing to check how the software performs under bulk volumes of HTTP traffic.

Hence, its recommended that you carry out performance testing to:

Evaluate production readiness

Assess against performance criteria

Do comparative analysis of performance characteristics of varied system configurations

Locate the source of performance complexities

Get started with correct performance testing technique today and give your clients business the required dose of competitive advantage !
