Step by Step Guide 2021
Enterprises are constantly striving to achieve a quality product for which the testing of software is essential. Software testing methods such as unit testing, integration testing, system testing, smoke testing and functional testing are of varying types. Smoke tests are important from these kinds of tests and should not be avoided in order to ensure high quality software.
What is Smoke Testing?
Smoke testing is a software testing process that validates whether or not the software build deployed is stable. This test method is designed to test the core functionality of a new build, and if the smoke test fails, it is very likely that the build will be immediately rejected by the QA team. As QA teams are involved in this process, the test is performed in a QA environment to ensure that the product is stable and fully functional. It is also referred to as ‘build verification testing’ or ‘confidence testing.’
Approaches for Smoke Testing?
There are two approaches to testing. These are manual smoke tests and automated smoke tests. Typically, the approach they follow varies from organization to organization.
Manual Smoke Testing:
This testing is done to ensure that the critical navigation path is as expected and does not hinder functionality.
Once the build is released to the QA teams, the test cases for high priority features are checked to identify the critical flaws in the system. If the test passes, the teams will proceed to the functional test and, if the test fails, the build will be rejected and sent back to the development team for corrections.
Once again, QA teams perform smoke tests on the new build version. It is then integrated with old structures to maintain the correctness of the system.
Automated Smoke Testing:
Smoke Testing can be performed using a set of automated test cases. Using the record and playback feature, recorded smoke test cases can be reused whenever new software builds are deployed.
It verifies whether or not the major functionalities are working properly. If the test fails, the corrections are made and the build is immediately redeployed. It helps to save the team’s time and effort.
STEP BY STEP SMOKE TESTING:
Following are the most essential and effective steps to conduct smoke testing.
Identify test cases:
This is a very important step in the smoke test. It is essential to identify the minimum number of test cases to cover the key features of the product so that they can be carried out quickly. Choose the necessary test cases that have already been identified by the programmers.
Create a test:
The identified smoke test can be used to construct test cases around them. Test cases are manually developed and automatically performed with test scripts.
Once the smoke tests have been developed, they can be carried out and results analyzed.
Evaluate the test :
After completing the test the results can be analyzed to determine if the construction is a pass or a failure. If the test is successful, it is submitted and sent back to development teams for re-build if the test failure occurs.
How important is a smoke test?
Obviously, it is important for good quality to thoroughly test your applications. Conducting a smoke test series is even more important as an answer to these preliminary questions is sensitive before moving towards other tests:
- Is it possible to initialize the application without errors?
- Does the login process work properly?
- What is the result of clicking the main menus or buttons?
Sizing a smoke test suite:
A suite should include an easy to manage number of tests to perform very quickly, even if it is fully automated, to be efficient and purposeful. There would be a good range for the number of tests between 20 and 50. The intention of this preliminary test suite can be defeated by too little or too much coverage.
Each smoke test should ideally meet the following criteria:
- Tests only core functions
- The test must be permanently reproducible
- Very quick running
- If few or no false positives are generated.
Think about automation of your tests, if you have not thought much. We understand why it may seem much easier to say than to do, given that many automation efforts are complete projects. It is worth the extra effort for non-trivial applications. There are many good reasons for your testing but the best reason is that tests are done faster, more consistently and automatically return results. This set of tests should be completed in five minutes or less.
The test of smoke is essential if software construction is to be stable or not. It helps in the early identification of defects and it tells if further testing or re-construction of the software is possible.
This helps to achieve high quality software applications that are stable. Therefore, this test process must be followed as it quickly assesses the basic features of a new construction and ensures that the structure for further testing is appropriate.
Thus, companies should recognize tests, when working on software products, as an essential test method to assess software quality.
