Why Software Testing is Necessary?

What is software testing?

Software testing or software QA is a discipline in software engineering that consists of execution processes and work methodologies with the finality of locating and removing software errors. It can also be understood as the process of validation and verification of a software program or application.

It is essential to bear in mind that testing is parallel to the software development process. As the product is built, software testing tasks are performed to prevent functionality issues and correct software deviations before release.

Why is testing important?

At a high level, software testing is essential to catch bugs in the software development process and to realize whether the software fulfills customer requirements and necessities. This enables the development team to correct bugs and produce quality software.

There are several junctures in the software development cycle where human error can lead to software that does not meet customer requirements. Here are some of the most common mistakes:

• The client/individual supplying the prerequisites on behalf of the consumer organization may not comprehend exactly what is required. He or she may forget to provide small details as well, which can lead to missing features.
• The person who is compiling the requirements may misinterpret them or not fully comply with them when documenting them.
• Errors can happen during the development phase due to human error, lack of experience, etc.
• Customers may not have the necessary bandwidth to test all product features, which can lead to end users encountering application bugs.

What is a tester

Software testers (also known as testers) plan and carry out software tests on computers to see if they are working correctly. They identify the risk of software bugs, detect errors, and then report them. They evaluate the overall performance of the software and suggest ways to improve it.

In many cases, the testing stage has been relegated to a final phase before going to production, and with such a limited time that, in many cases, they cannot guarantee effective testing.

Profiling a tester

The tester is like the German Shepherd dog breed. It is said that the German Shepherd is not the best at anything, but he is the second-best at everything. Extrapolating into the computing world, the tester must be the second most knowledgeable person regarding the project (immediately after the project manager), the architecture (after its architects), the design (behind its designers), and the development (following the developers). There is only one case in which the tester should be the one who knows the most about something, and that is testing. In addition to this, the tester must know how to express these mathematical terms easily and clearly.

How to implement a testing service from scratch

Implementing a testing service from scratch is a complex and time-consuming duty. In most projects, we see that small but effective steps are taken towards a QA service through continuous integration. Steps such as committing people specialized in said fields. Finally, the implementation of tools such as Testlink for test management, SonarQube to evaluate the quality of the code, Jenkins for continuous integration, or Selenium for test automation are commonly employed with the purpose of producing the best possible product.
