Smoke testing is also called build verification testing.  Smoke testing is performed to test the fundamental and sensitive features of an application or software before testing in depth. It illustrates whether the software constructed is steady or not. This testing technique is performed after the software construction is completed by the development and the technical team. 

Purpose of smoke testing

Smoke testing is a software testing technique. This testing is performed after the build of the software. It is performed for the following purposes:

  • Smoke testing concentrates on the work pattern of the primary and secondary features of the application.
  • Through the smoke testing, it is decided if the software built is verifiable or not.

Features of smoke testing

Other than determining if the software constructed is deductible or not, software testing has the following features which explain its importance in software testing. The features of smoke testing are:

  • It recognizes the crucial business-functionalities that software or an application must assure
  • It saves the time and efforts of the testing team by revealing the obvious errors.
  • It depicts and implements the important functionalities of the system.
  • The smoke testing can be automated or non-automated.

Sanity testing

Sanity testing is also called a variant of regression testing. This testing is performed to check the accuracy of the just added attributes and components. Its task is to make sure that the defects fixed do not affect the working and implementation of the existing code. It also assures that the moderations made do not affect the software performance.

Smoke testing VS sanity testing

Smoke testing is software testing performed at the beginning, after the completion of the construction of the software. As mentioned above, smoke testing tests the major functionalities of the software built. If the software functions well enough then the next testing takes place, else the software is sent back to the development team to fix the issues.

Unlike smoke testing, sanity testing is performed after the recommended changes are made in the software. Its main task is to make sure that the changes made in the software are error-free and does not create new errors in the existing functionality of the software.

SANITY TESTING

1. Smoke testing is performed to measure the testability of the system or software.1. Sanity testing is performed to measure the rationality of the system or software.
2. This testing can be performed by the developers as well as testers.2. This testing can only be performed by professional testers.
3. Smoke testing also confirms the sensitive performance of the system or software.3. Sanity testing confirms the modified performance of the system or software.
4. Smoke testing is also called acceptance testing.4. Sanity testing is also called a subset of regression testing.
5. This testing takes place at the beginning, after the construction of the software.5. This testing takes place after the completion of regression testing.
6. It can be documented or scripted.6. It is neither documented nor scripted.

Software testing 

Software testing is performed to find bugs in the system or product developed. It also must verify if the result has matched with the expected result. Its work is to confirm if the software or system does what it claims to do.

Why perform software testing?

  • Software testing does a lot of verification in many areas. So it makes it easy to add new features.
  • It is performed to determine the working of the software or product.
  • It also determines if the product will satisfy the customer by verifying the current and expected outcomes.
  • Software testing regulates product quality.

Smoke testing VS Regression testing

As mentioned above, smoke testing is performed to check the stability of the software built. It tests whether the major functionalities of the product or software is working efficiently or not.

Regression testing tests whether a modification made has caused any change in the existing performance of the product or software. It also decides the performance of the new code. It also assures that no bugs exist in the software built. It is also a BlackBox testing technique.

 The differences between smoke testing and regression testing are:

SMOKE TESTING

REGRESSION TESTING

1. It is a beginning level testing.1. It is testing at the depth level.
2. It verifies the testability of the software or the system.2. It confirms the rationality of the system or the software.
3. It is cost-efficient.3. The cost of regression testing is more than the smoke testing.
4. It requires less time.4. It requires more time.
5. It requires less manpower.5. It requires more manpower.
6. It is performed by software developers.6. It is performed by professional testers.

When software or an application or a product is built, it has to go through various testing to determine if the results are ideal. The built product also needs to satisfy the customer expectations since a huge amount is invested in it. Smoke testing plays a crucial role in the testing pattern. It determines if the product built can go through further testing. It is said that if the initial step is accurate, the coming steps will be accurate too. So this smoke testing is the first step that should be accurate for the better performance of the software.
