Destructive testing is a kind of software testing used to identify flaws in a software program. It is a testing approach in which an application is purposefully forced to crash in order to verify its resilience and discover the site of breakdown.
Unlike the other testing methods that examine an application's functionality, this methodology examines the unexpected user behavior within the program.
It is not essential to understand the specified requirements of a software system to do Destructive Testing. But, some understanding might aid in the development of an effective testing method.
It aids in understanding anticipated program behavior whenever the product is used incorrectly.
It aids in testing the resilience of a software system.
You will look for the following items during Destructive Testing.
Correct software behavior
Inappropriate software behavior
Incorrect input data
Proper output data
Several actions are involved in destructive testing, such as building a series of test scripts, implementing test scripts, reporting defects, resolving defects, and presenting clients with a pass or fail statistics at the conclusion of the cycle.
There are several methods for testing Destructive Testing. Here are a few examples −
Method of failure point analysis − It is a tour of the system that assesses what may go wrong at different phases. This plan may benefit from the assistance of a BA (Business Analyst).
Tester peer review − Get a colleague tester who is less acquainted with the platform/functionality to assess or examine your test scenarios.
Business review of test cases − Consumers or specialists may think of countless appropriate situations that testers may not even have explored or ignored because their whole attention would be on validating the objectives.
Conduct exploratory testing, using run sheets − Exploratory testing with run sheets can let you identify what's been tested, rerun the tests, and manage your testing coverage.
Use other sources − might request that someone disintegrate the software product and examine it for different scenarios.
The many Destructive Testing Methods utilized in Software Engineering are as follows −
Alpha / Beta Testing
Acceptance Testing, etc.
The following Destructive Testing Techniques can be utilized with adjustments −
White Box Testing
Smoke Testing, etc.
Specific testing criteria must be met when doing Destructive Testing.
Improper input data should not be processed or accepted by the program.
Irrespective of the legitimacy or quality of the input data, the program must always generate accurate output data.
In this methodology, an application is purposefully designed to fail in order to test its resilience.
It is not essential to understand the specified requirements of a software product to do Destructive Testing.
