It is a special type of reliability that consists of multiple raters or judges. Inter-Rater Reliability is otherwise known as Inter-Observer or Inter-Coder Reliability. It is called so as the testers are conducting the test in two forms at the same time. 2) Parallel or Alternate form of Reliability In such a case he cannot be considered a ‘reliable’ source. After 6 months he takes the same ‘IQ test’ and scores 68 points. Here, it is very important to note that the length of the test remains the same if we have 10 steps in a test case, then the number of steps will remain the same for performing the test next time.Ĭonsider the particular Example of a person attending an ‘IQ Test’ and scoring 144 points. Usually, a Reliability of 0.8 or more means that the system can be considered a highly reliable product. Then we can say that the test is ‘Reliable’. We are getting a high correlation in the results. 1) Test-retest ReliabilityĬonsider the following situation in which we are testing a functionality, Say at 9:30 am and testing the same functionality at 1 pm again. Fundamental Types to Gauge the Reliability of SoftwareĮnlisted below are a few fundamental types to gauge Software Reliability. While doing Reliability Testing, we must check the environment constraints like memory leakage, low battery, low network, database errors, etc. If it shows the same or similar result then the software can be considered reliable.Īlso, we can test the Reliability by executing the test cases for a particular amount of time and check if it is showing the result correctly without any failures after that particular period of time. The test cases should be executed at regular intervals so that we can cross-check the current result and the previous result and verify if there is any difference between them. Test cases should be designed in such a way in it ensures the total coverage of the software. To find the faults present in the system and the reason behind them.Given below are the scenarios where we use this testing: Reliability testing is performed to ensure that the software is reliable, satisfies the purpose for which it is made, for a specified amount of time in a given environment, and is capable of rendering a fault-free operation. If we are able to repeat the test cases and if we get the same output consistently, then the product is said to be ‘reliable ‘. Reliability testing is concerned with the quality of the software and the standardization of products. Hence, we need to have accurate data on which the users can rely on. In today’s world, Software Applications are being used in each and every aspect of our life including healthcare, government sectors, telecommunication, etc.
