Functional Testing, its types and its automation process

• Line coverage
• Code path coverage
• Method coverage

2. Smoke Testing:

We perform this task after releasing each build to ensure that the software stability is intact and not facing any anomalies. Smoke testing ensures the appropriate and consistent functioning of the basic functionalities and the important features. This also ascertains the absence of show stopper bugs in the release done. We make the decision on proceeding with further testing based on the outcome of smoke testing. Ensure basic functionality/user journey works and there are no show stopper bugs present.

3. Sanity Testing:

After performing smoke testing, we usually run this to verify that every major functionality of an application is working perfectly, both by itself and in combination with other elements. Sanity testing is a subset of regression testing. This also checks the proper working of new functionality added to an application.

4. Regression Testing:

Regression Testing ensures that changes to the codebase (new code, debugging strategies, etc.) do not disrupt the already existing functions or trigger some instability. We test the complete end-to-end functionality of the application software here after including the new feature or change in it.

5. Integration Testing:

After conducting regression testing on individual modules of the application software, integration testing ensures proper integration of all the modules. That is, all the modules work fine and in proper sequence when used combinedly without breaking the product. If a system requires multiple functional modules to work effectively, integration testing is done to ensure that individual modules work as expected when operating in combination with each other. It validates that the end-to-end outcome of the system meets these necessary standards.

6. Beta/ Usability Testing:

In this stage, volunteers or a limited set of users for whom the new feature or changes made in the application software have been enabled for usage will test the product in a production environment. This stage is necessary to gauge how comfortable a customer is with the interface. We take their feedback for implementing further improvements to the code.

Process Workflow for Functional Testing

The overview of a functional test includes the following steps:

1. Create input values with boundary conditions in mind.
2. Execute test cases with defined test steps.
3. Compare actual and expected output.

For example, ask yourself: Can you create test scripts on one OS and run them on another? Do you need UI automation, CLI automation, mobile app automation, or all of them?

4.It must provide features specific to your team’s requirements.

For instance, if certain team members are not comfortable with a certain scripting language, the tool should support conversion to other script languages that they may be better versed in. Similarly, if you need specific reporting and logging or automated build tests, the tool must be able to provide the same.

5.In case of changes to the UI, the tool must support the reusability of test cases.
