Benchmark Testing in Software Testing
Prerequisite : Software testing
Every developed software application pass through functional testing and non functional testing to ensure that it satisfies the business requirements. Not only business requirements are observed but also all the performance standards like product behavior, speed, functionality, stability, scalability, reliability, load capacity, and performance under stress etc. are monitored. Benchmark testing is a part of the performance testing. So now let’s go little bit deep to know more about this benchmark testing.
Benchmark Testing :
Benchmark testing is considered as a part of Software Development Life Cycle (SDLC) which compares performance testing results against performance metrics to determine current performance and any changes needed to improve performance. It covers software, hardware, and network performance. Mainly it focuses on present and future releases of an software product/service to maintain high-quality standards.
A benchmark must be repeatable as well as quantifiable in terms of determining performance of the product/service. For example a product’s response time needs to be stable amongst different load conditions which refers to repeatable of benchmark and user spending how much time on a product, within how much time getting the actual service refers to quantifiable of benchmark.
For an example, here we will take two cases of benchmark testing. Let there is an web application and we will see what are the benchmark components for database performance of web application and client server application of web.
Components that are Benchmarked in case of data base :
- Table Space Configurations
- Hardware Configurations
- SQL Queries
- SQL Triggers
- SQL Indexes
Components that are Benchmarked in case of client server :
- Browser compatibility
- Broken Links
- Load Time
- HTML compliance
Importance of Benchmark Testing is :
- For performance analysis of a software product/service with competitors.
- It is essential for implementing quality standards of software product.
- It is essential for implementing SLAs (Service Level Agreements).
- It is essential to practically establish user/customer experience.
- It allows to point out the mistakes to be avoided.
- It allows to determine current performance and any changes needed to improve performance.
Phases of Benchmark Test :
Benchmark test involves four phases i.e.,
- Planning Phase –
This phase involves identifying and defining and prioritizing standards and requirements. Benchmark test process defined and different benchmark metrics are decided.
- Analysis Phase –
This phase involves setting the goals and objectives and identifying the error and resolve them to get a quality product.
- Integration Phase –
This phase involves the agreement between functional and non-functional requirements and share outcomes with concerned business in getting approval.
- Action Phase –
This phase involves developing the test plan and documentation, implementing the performance tests, measuring the performance, calculating results and running the process continuously.
Along with this there are four benchmark testing techniques phases i.e.,
- Benchmark preparation
- Benchmark test creation
- Benchmark test execution
- Benchmark test analysis
Advantages of Benchmark testing :
- Performance Improvement
- Changed focus
- No extra cost incurred
- Identification of essential activities
Disadvantages of Benchmark testing :
- Standard stability
- Increased dependency
