The Ultimate Software Testing | Reliability Testing Checklist

Posted on Author qatestingleaders@gmail.com Comments(4)

Reliability testing is a technique for determining a software’s capacity to perform in a specific environment, which aids in the discovery of bugs in the software’s design and functionality. It is defined as a type of software testing that assesses whether a piece of software can operate without fail for a set period of time in a given environment.

The goal of reliability testing is:

  • To discover the pattern of recurring failures.
  • Determine the number of failures that have occurred over a specified time period.
  • To determine the primary cause of failure.
  • After fixing the faults, perform performance testing on various modules of the software product.

Types of Reliability Testing:

Below are the different types of reliability testing:

Feature Testing:

This testing entails the following three steps:

  • The software should utilize each function at least once.
  • There should be less interaction between two or more functions.
  • The correct execution of each function is essential.
Regression Testing:

Regression testing is carried out whenever new functionality is added, old functionality is deleted, or bugs are corrected in an application to ensure that no new bugs are introduced as a result of the addition of new functionality or the fixing of existing bugs.

Load Testing:

Load testing checks if the program can handle the required load without crashing. In this, we test the software’s performance under extreme conditions.

There are three types of reliability testing research: –

  • Modelling
  • Measurement
  • Improvement

Measurement of Reliability Testing:

  • Mean Time Between Failures (MTBF):
    Measurement of reliability testing in terms of mean time between failures (MTBF).
  • Mean Time To Failure (MTTF):
    The time between two consecutive failures is mean time to failure (MTTF).
  • Mean Time To Repair (MTTR):
    The time taken to fix the failures is mean time to repair (MTTR).

MTBF = MTTF + MTTR

  2. This is the perfect blog for anybody who wants to find out about this topic. You know a whole lot its almost hard to argue with you (not that I actually would want toÖHaHa). You certainly put a fresh spin on a topic thats been written about for a long time. Excellent stuff, just wonderful!
