RANDOM TESTING

SYSTEM TESTING

Random testing is a testing technique where programs are tested by generating random and independent inputs. It is a type of black box testing. The results of output generated are compared with the software specifications to verify if the result is correct or not. There are some strengths and weakness of random testing.

The strength of random testing are:

  1. It is inexpensive to use
  2. It does not have any bias
  3. The bugs are found very easily and quickly
  4. If software is used properly it will find the bugs.

The weakness of this testing is:

  1. It is capable of finding only basic bugs
  2. It is precise when specifications are imprecise.
  3. This technique compares poorly with other techniques to find the bugs
  4. This technique will create a problem for continuous integration if different inputs are randomly selected on each test.
  5. Some think that white box testing is better than this random testing technique

The characteristics of random testing:

  1. It is performed where defects in a software application is not identified by the regular intervals.
  2. Random input is used to test the system performance and its reliability.
  3. Saves time and effort than actual tests.
  4. Other testing methods are not used.

The common example of Random testing is: use of random integers to test the software function that returns the results based on those integers. Specifically when dealing with integers or other types of variables. Random testing is random as a set of random inputs that are used, in other words testers are bound to choose set of integers rather than infinite set.

Types of random testing:

  1. With respect to the input

Random input sequence generation, random sequence of data inputs and random data selection from existing database.

  1. Guided vs Unguided

Undirected random test generation with no heuristics to guide its search and directed random test generation. Eg. adaptive random testing.

Most of the criticism about random testing is about misapplication of the technique. The key problem of random test is generating input that are part of the domain of the software under test. Random testing is great for testing

  • fault behaviour
  • data validation
  • Adherence to specifications
  • Concurrency

  3. Random testing to test the software application by randomly generated inputs to look for any defects.This is part of the black box testing.
    Characteristics include: This test is implemented to test the application to find out defects if they are not identified during intervals.
    It is inexpensive, it is better than white box testing. This is to check the performance and reliability of the software. save time and effort than actual tests.

  6. What is random testing?
    Random testing is a black-box software testing technique where programs
    are tested by generating random, independent inputs.
    Results of the output are compared against software specifications
    to verify that the test output is pass or fail.

    What are the characteristics of random testing
