What Is smoke testing and Why Is It Important?

smoke testing

In software testing and auditing, smoke testing is sometimes referred to as black-box testing due to its lack of sensitivity to outcomes, which makes it more generic than sensitivity testing. In software testing and debugging, smoke testing is the first stage testing to reveal only few serious failures, usually very simple, for instance, the rejection of a proposed software release by testers. The second stage of testing, which is often called post-testing, entails additional work with a system that passes the first stage but then fails a second time, in which case the testing team will need to re-run the complete process. This can be quite costly and time consuming because it needs to be repeated for each failure. A quality improvement initiative or QA effort must consider the cost and resources required for detecting and fixing the errors or bugs before they cause severe problems.

How to know about smoke testing and Why Is It Important?


In contrast, black-box testing deals with missing or false negative results that are usually caused by human error, access control, server issues, hardware failure, network issues or other situations where the tester cannot achieve a positive result. In the recent years, there has been a trend in software testing and debugging for different types of testing and verification methods. Different tests are based on different types of inputs and the results of each test are also different in their distribution of failures. For instance, a test for a database application would produce different results depending on whether it is being run under a single user, multiple user, or replicated environment. Similarly, the type of input used for the testing method should also determine the results. Some types of inputs to produce different types of outputs, while some produce results only under specific conditions.


Another reason why many software testers choose black box methods of testing is the fact that they produce faster and better results than the traditional ways. In traditional methods, testers search through a large area of memory to identify the issues, while in different types of software testing and debugging, these issues can be isolated and quickly identified. In addition, the testers can easily modify or maintain the test case after its completion, which is not possible with the traditional test cases.
