Depending on your testing objectives, you should decide between smoke testing and regression testing. Regression testing checks offer information on software performance after some capabilities have been added or changed, whereas smoke testing establishes the stability or fallibility of software prior to conducting additional testing. Let us debate Smoke testing Vs Regression testing to better understand more about it.
What is Smoke testing?
A relatively small number of tests known as smoke tests are performed to ensure that a software project's essential features are stable. Every time a new software build is released, regardless of whether it adds any brand new features or just patches bugs, it is customarily carried out. It is critical to remember that more thorough testing is not covered by smoke testing because it only concentrates on essential functionality.
What is Regression testing?
On the other hand, Regression testing is a thorough testing procedure to guarantee that each feature in the software being tested operates as intended. The product is prepared to be made available to end consumers if all regression tests pass. Regression testing may be required following any code modification, including bug patches and the introduction of new features. Regression testing's major goal is to test more than just the update in order to make sure that the recent modifications haven't had a detrimental impact on other parts of the software project.
Smoke testing Vs Regression testing | Difference between Smoke testing and Regression testing:
- Smoke testing is surface-level testing to verify the stability of the system. Regression testing is deep-level testing to verify the rationality of the system.
- Test cases of the smoke tests are a part of regression testing and cover only the core functionalities. Regression testing is obtained from functional specifications or software specifications.
- The developers carry out smoke tests. Professional testers do our regression tests.
- A regression test always follows a smoke test. A regression test is always carried out throughout the testing phase.
- The cost of a smoke test is low. The cost of regression testing is a little bit high.
- In order to determine whether to accept or reject the build, smoke tests are swiftly conducted. Regression tests do not have the authority to approve or disapprove a software build for further testing.
- The requirement of time and manpower is less than regression testing. The requirement of time and manpower is less than smoke testing.
- Smoke testing is documented or scripted. Regression testing is not documented or scripted.
- Build verification testing is another name for smoke testing. Regression testing is not by any other name.
- Smoke testing is typically a rapid test that generates immediate feedback. Regression testing is generally time-consuming and the result is collected over an extended period.
- A smoke test is non-exhaustive/shallow by nature. Regression testing is depth by nature.
Conclusions:
Smoke testing and regression testing are each significant in their own right. Each has its own strategies, approaches, and issues. With the use of comparison and difference, we have given the difference between these two testing methodologies in this post. I hope you enjoyed reading it.
