INTRODUCTION TO SMOKE TESTING AND IT’S IMPORTANCE
All the industries are today focused on producing and delivering the best quality outcomes to their customers and their markets, and the same goes with the software development sector as well and in order to achieve that, productive software testing is all that is required as it is the key element to reach the target.
There are numerous ways to test the software that includes unit testing, API testing, sanity testing, smoke testing, integration testing, functional and non – functional testing, and so on. Among all these listed ways, smoke testing is the one that is very crucial in its own way and this blog is focused on it that will cover different aspects of this methodology.
ROLE OF SMOKE TESTING
The smoke testing cycle that is performed by QA teams in the test environment ensures that if the deployed build is achieving the core target and whether it should be tested further or not. In other words, if the build fails the test scenario of core functionality, then it will be rejected immediately by the QA team, and they will stop testing it. It is drafted to ensure the core functionality of the fresh build.
This kind of process and verification method also checks the stability and complete functional aspect of the build and if it fails the smoke testing, then there is no meaning to go ahead with testing it.
Hence, in a nutshell, the smoke testing is very promising to confirm if a build is stable enough to be tested further.

SMOKE TESTING PURVIEW
With smoke testing, most of the build issues can be identified in the early stages of the program development and can be helpful for the correction of the same so it can be said that smoke testing is a frequent regression test of the prime functionalities and manifests if the build is ready to carry out the testing further.
This method can be adopted by the developers and the build passes the test then only it can be deployed for further testing else should be rejected.
Here is a pictorial representation for the above:
WHEN TO DO SMOKE TEST?
Smoke testing should be performed at the initial phase of the testing life cycle as it checks very soon the productivity of the build and ensures if the elementary requirements can be fulfilled or not. Whenever a fresh build is deployed, or any change has been made in the build then smoke testing should be carried out.
Software development is always divided into different sprints so that all the corners are covered hence it is important that each sprint has a stable code so smoke test takes very little time to fulfil this need before the regression testing and, in this way, we also save our precious time as well.
The objective of smoke testing is to test the important functionalities of a system and not to execute the exhaustive test scenarios.
WHAT IF THERE IS NO SMOKE TEST?
It is necessary for every fresh build being deployed to be tested aggressively with smoke testing because it is possible that without it, certain critical bugs would not be detected and can be a showstopper later in other test cycles. It is also possible that without smoke testing, an integration error can be generated.
BENEFITS OF SMOKE TESTING
A. Identification of major issues in initial test phase that saves time.
B. Assurance of stability to test further.
C. Deployment of quality products at quicker rate as it delivers quick feedback.
D. Smoothens the integration and easy to track development progress.
STEPS TO FOLLOW FOR SMOKE TESTING
A. Run smoke tests at the initial phase of the project.
B. Consistently maintain all the smoke tests.
C. It should not take much time.
D. Test scenarios should be carried out for each deployment and sprint.
E. If possible, automate the smoke test scenarios to reduce the time and cost further.
F. Conduct this test for all key features for the deployed build.
There are three types of Smoke testing namely: – Manual Method, Automation Method and Hybrid Method.
The manual method is the most commonly used smoke testing method under which the smoke test cases are tested manually for the fresh build and the newly added features. Here, the scripts have to be modified on the basis of each requirement.
Automation smoke testing is also applied when we need to use the batch of automated test cases and the build can be tested immediately every time a fresh issue is found.
Hybrid smoke testing as the name suggests is the merger of both mentioned methodologies and its objective is to enhance the overall performance of Smoke Testing.
With everyday technical advancements, the market and the consumers need the well productive end results in the forms of major platforms i.e. web-based and mobile-based and it is only possible with the help of software testing.
As we have mentioned earlier that there are so many kinds of software testing methods and among all these, smoke testing stands an important way, as it is being carried out with each
developed build and to detect if it has been left with some broken links or it should be deployed further to test more.
With many benefits in its pocket, smoke testing should be taken into consideration as it saves time and calculates the stability early, that saves the cost as well.
