Software Reliability Testing Training Course

Software reliability testing training course will cover proactive ways to use well-established systematic test planning and design techniques that generate value, not just busywork.


What is Software Reliability Testing?

Software reliability testing methods evaluate the software’s functionality, under certain environmental conditions and for a limited amount of time. In other words, software reliability testing refers to the techniques and methods of evaluating the reliability of the software. Software reliability testing allows you to explore the problems that might occur in the software design and functionality.

Software Reliability

Software reliability is the likelihood that software works as it is intended under a given environmental condition and for a specific amount of time.

Probability = Number of failing cases / Total number of cases under consideration

Input space is defined as the set of all possible input states. The reliability of software would be the output space associated with the given input space and software.

For reliability testing, data is collected from different phases of the software development, from the conceptual design through the final execution. However, the number of tests is limited due to the cost and time burdens. Statistical samples are attained from the software products to test for the reliability of the software. Once adequate data is available, statistical studies are thorough.

In order to accomplish satisfactory outcomes from reliability testing, some reliability characteristics need to be taken into considerations. For example, Mean Time to Failure (MTTF) is measured in terms of three factors:

  1. Operating time
  2. Number of on/off cycles
  3. Schedule time

Software reliability is calculated in terms of mean time between failures (MTBF). MTBF consists of mean time to failure (MTTF) and mean time to repair (MTTR). MTTR is the time required to fix the failure.

Reliability Testing Objectives

Primary Objective

To evaluating software performance under given conditions without any type of corrective measure using known fixed procedures considering its specifications

Secondary Objectives

  1. To identify perceptual configuration of recurring failures
  2. To identify the number of failures repeating in a specified amount of time
  3. To find the mean life of the software
  4. To explore the major cause of failure
  5. Checking the performance of various parts of software after taking preventive actions

Some Restrictions

  • Response of the software should be defined in given conditions
  • The objective should be feasible
  • Time constraints should be provided
