Why Web Service Performance Testing Matters for The Success of an Application?

Web service Performance testing is a kind of testing that tests, confirms and validates operational abilities of an application or a website. It consists of a broad class of techniques designed to observe and fix the quality and skills of certain characters of the system’s operation. This shows how the system acts in varied circumstances.

Performance testing is generally recognized as one of the necessary parts of the software testing method as it directly deals with the software skills to do what it supposed to do.

Why do you require web service performance testing?

While it may look like no big deal but Performance testing is rather complicated. The pieces of it are comparatively easy — but the overall method requires to be thought-through step by step to gain the most effectiveness.

The first and foremost thing the tester requires to do is to establish a plan for testing routines.

If not — then the info will be simply a jumbled mess with no precise use.

Another necessary aspect of Performance testing is collecting data on the system’s activity in a particular situation with a workload of different extent. The outcomes of performance tests serve as a basis for future feature-specific tests. This provides a clear conclusion of systems limitations and offers direction on what to improve and change.

The purpose of performance testing The main goal of Performance testing is rather clear — to determine how much workload the system can take before breaking down or hindering in terms of user exercise and detect weak points of the system with complete specifics regarding the source of the problem before it costs a business.

Aside from assisting in locating problems but it also gives directions for possible solutions via results and related tests. It makes clear when and why the problem occurred and what makes it happen.

A fundamental set of web service performance testing specifications: • Evaluating the system’s workload capacities against standard criteria.

• Under normal situations.

• Under peak circumstances.

• Determining the response time.

• Average under max load.

• Detecting doubtful points in the system’s process.

• Identifying breaking points and bottlenecks in the process.

• Analysing test results on various systems.

Performance testing methods are usually broken down into certain types: Stress — studies the system’s performance and checks its stability in situations when the hardware is inadequate to maintain software. I.e. if CPU, memory, disk space are lacking.

Spike — aimed at studying particular segments of performance upon rising load way beyond the extended scope for short periods.

Scalability — regarding a capability to adapt to the varying workload. Specifically — testing user load, various possible actions, data volume.

Volume — used to control the performance of the operation by subjecting the program to a large volume of data.

Endurance — used to study the system’s performance over extended periods. Tests the system with the predicted amount of load to check for memory leaks, processual fails or mixed acting.

Load — involves testing the system with increasing load until it reaches the breaking point to define threshold value.

The most common parameters are: • • • •

Response time (average & peak) Amount of errors that occurred throughout the test.

Throughput ability.

CPU / Memory load.

In conclusion Every application is a strong knot of several functions connected. This means every element of the program has to be strong enough to carry the extreme and excessive workload and don’t fail inadequately in the process. But that is not the thing that happens on its own.
