What Is Pesticide Paradox And How Do You Fix It?

Why is it important to avoid the pesticide paradox?

You run the same set of test cases and they all pass.

The old set of test cases are incapable of identifying these new bugs.

This is called Pesticide Paradox.

To avoid this you need to update your test cases with each cycle and add new cases to the old set..

What are the 7 testing principles?

The seven principles of testingTesting shows the presence of defects, not their absence. … Exhaustive testing is impossible. … Early testing saves time and money. … Defects cluster together. … Beware of the pesticide paradox. … Testing is context dependent. … Absence-of-errors is a fallacy.

Who is responsible for acceptance testing?

User acceptance testing (UAT) is the responsibility of the users. By ‘user’, we are typically referring to those stakeholders who will use the system to support their roles in the day to day operation of the business. At least some of these users have hopefully been involved in the elicitation of the user requirements.

What is absence of error fallacy?

The absence of Error is a Fallacy i.e. Finding and fixing defects does not help if the system build is unusable and does not fulfill the user’s needs & requirements.

What is STLC?

STLC stands for Software Testing Life Cycle. STLC is a sequence of different activities performed by the testing team to ensure the quality of the software or the product. STLC is an integral part of Software Development Life Cycle (SDLC). … STLC provides a step-by-step process to ensure quality software.

What is the entry and exit criteria in testing?

Before running performance testing, certain conditions are set, which are called the entry criteria. These conditions are based on approvals, testing environment, and many other factors. Whereas, specific expectations are documented after the test is complete, and they are known as the exit criteria.

What is white box testing techniques?

White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing).

What is difference between verification and validation?

Validation is the process of checking whether the specification captures the customer’s needs, while verification is the process of checking that the software meets the specification.

How can you overcome the pesticide paradox?

Methods to prevent pesticide paradox:To write whole new set of test cases to exercise different parts of the software.To prepare new test cases and add them to the existing test cases.

What is pesticide paradox Mcq?

What is pesticide paradox? a) If the same tests are repeated over and over again , eventually the same set of test cases will no longer find any new bugs. b) A small number of modules contain most of the defects. c) Testing can show that defects are present , but can not prove that there are no defects.

What is a defect life cycle?

A Defect life cycle, also known as a Bug life cycle, is a cycle of a defect from which it goes through covering the different states in its entire life. This starts as soon as any new defect is found by a tester and comes to an end when a tester closes that defect assuring that it won’t get reproduced again.

What is BVA and ECP with examples?

Boundary Value Analysis and Equivalence Class Partitioning are the most common technique in Black-box Testing Techniques for test case design. Both are used to design test cases for validating a range of values for any given input domain.

What are the testing methodologies?

Why is exhaustive testing impossible?

Why Exhaustive Testing Is Impractical and Impossible It is not possible to perform complete testing or exhaustive testing. … The domain of possible inputs of a program is too large to be completely used in testing a system. There are both valid inputs and invalid inputs. The program may have a large number of states.
