What is meant by pesticide paradox?

When a small number of modules contains most of the bugs detected or show the most operational failures. Pesticide Paradox: If the same tests are repeated over and over again, eventually the same test cases will no longer find new bugs. This is what pesticide paradox is actually referring to.

Why is it called pesticide paradox?

In 1990, Boris Beizer, in his book Software Testing Techniques, Second Edition, coined the term pesticide paradox to describe the phenomenon that the more you test software, the more immune it becomes to your tests. The same thing happens to insects with pesticides (see Figure 3).

What is pesticide paradox and how do you fix it?

Pesticide Paradox principle says that if the same set of test cases are executed again and again over the period of time then these set of tests are not capable enough to identify new defects in the system. In order to overcome this “Pesticide Paradox”, the set of test cases needs to be regularly reviewed and revised.

Why is it important to avoid pesticide paradox?

This simply means that as the same test suite is run multiple times, it becomes ineffective in catching bugs. And moreover, these test sets will also fail to catch parts of new bugs introduced into the system with recurring enhancements and fixes.

What are the 7 testing principles?

According to International Software Testing Qualification Board there are seven principles that should be considered when developing the testing strategy for a software project/product.

• 1) Testing shows presence of defects.
• 2) Exhaustive testing is impossible.
• 3) Early testing.
• 4) Defect clustering.
• 5) Pesticide paradox.

Who is the best person to catch a defect?

Business Analyst is the best person to catch a Defect – Basic concepts of Software Testing.

How should we tackle the pesticide paradox?

To overcome this ‘pesticide paradox’, the existing test cases need to be regularly reviewed and revised, and new and different tests need to be written to exercise different parts of the system. This will help with finding more defects. Testing is done differently in different contexts.

What is the paradox of applying pesticides to a pest?

The paradox of the pesticides is a paradox that states that applying pesticide to a pest may end up increasing the abundance of the pest if the pesticide upsets natural predator–prey dynamics in the ecosystem.

When did Boris Beizer invent the pesticide paradox?

The Pesticide Paradox In 1990, Boris Beizer, in his book Software Testing Techniques, Second Edition, coined the term pesticide paradox to describe the phenomenon that the more you test software, the more immune it becomes to your tests. The same thing happens to insects with pesticides (see Figure 3).

Which is the best definition of a pesticide?

Definition of pesticide : an agent used to destroy pests : a chemical that is used to kill animals or insects that damage plants or crops : a substance used to destroy pests (as insects or weeds) : an agent used to destroy pests

What’s the paradox of spraying orchards for mites?

Spraying the orchards kills both mites, but the effect of diminished predation is larger than that of the pesticide, and phytophagous mites increase in abundance.
