Software testing holds a great importance in the life cycle of software development. Software development company like GA Technocare Technology has been able to build successful and smooth-functioning software programs only by putting them through various software techniques.

The role of testing is considered essential because it helps to figure out the flaws in the design and validates if the developed script of codes can meet the designated requirements.

The software is put through sturdy functional testing to verify its functionality. Let’s see the various aspects of functional testing,

1.Unit testing

It is as a defined procedure of custom software development where each component of a module is tested separately. This ensures that every unit of the program functions well with respect to the way it has been designed.

It is the first level of testing that is usually performed by the developers. They review and rework on the code in case of any abnormality.

2.Integration testing

This stage of testing involves integrating the components of the software and verifying if the whole unit is working properly without any interruption.

Independent developers or testers can perform this stage of testing. They merge the tested components, review them as a whole, and redesign the codes if a bug gets detected.

3.System testing

Any custom software development company includes the system testing as a part of the development process to make sure that the combined set of modules works swiftly and comply with various devices for which it has been designed.

Most of the times, the skilled testers perform this stage of testing as it is a part of the black-box testing method.

4.Sanity testing

After the components of the software have been fused and tested individually as well as a whole, the reported issues are fixed. Sanity testing plays the critical role to verify if the infused corrections in code have not opened the gateway to other irregularities.

If yes, then the issues are reported, developers fix them, and testers again check if the software is sane.

5.Smoke testing

The software development company in India like GA Technocare uses this stage of testing to validate the functioning of the features. It ensures if the developed program can be put through the further testing procedure or it requires a fix-up.

It unveils the integration issues and reports problems at a very early stage.

6.Interface testing

This phase of testing confirms that commands are received and executed in a hassle-free manner. It checks that every API and integrated modules perform well from the perspective of the user as well as communication with the devices is secure and fast.

7.Regression testing

Any software development agency performs this testing to make sure that the previous fix-ups did not deliver any new abnormality into the system. All the changes and modifications in the codes are tested to reduce risks at the further stage.

8.Beta/ acceptance testing

It is the final stage of functional testing that requires inputs and feedback from the end user to make a final assertion of acceptance. This assures that the system is ready to use and it fulfils the requisites on the basis of which it was developed.

Conclusion

Each phase of testing has its own importance and none can be excluded if the end product has to be an efficient software program.
