Software Testing and QA

The architectural quality of the software is ordinarily difficult to maintain: It depends on the developer team’s skills and guarantees by code analysis and debugging. However, there is a practical side covered by peculiar quality control actions: quality assurance and testing.

The two terms relate to totally different phases of software quality supervision. Notwithstanding the general purpose of realization that a product is of the excellent quality, both organizationally and operationally, they use different approaches to this task.

QA concentrates on the organizational side of quality management, observing the sequence of the production process. A company has to assure that processes are streamlined and fitted as per the quality norms established for software products.

Testing is the primary action pointed to identifying and fixing tech concerns in the software code and estimating the overall product utility, production, safety, and adaptability. It has a very tight focus and it can be done by the test engineers alongside the development process.

The main pronciples of Software Testing

KitRUM is fundamentally an enterprise software company. During our years of work, we have accommodated many small, medium and large businesses and enterprises. This practice allows us to build a process that guarantees great performance for your company.

Early testing

The price of a mistake increases during the SDLC. Consequently, it is essential to begin testing the software as early as possible so that the identified bugs are fixed.

Testing reveals the existence of errors

The purpose of testing is identifying the errors and bugs. However, we can’t be convinced that there are no bugs. We test software to minimize the number of flaws.

Pesticide paradox

Applying the identical test every time won’t allow you to uncover more bugs. It is crucial to examine and modernize the tests repeatedly to adjust and get more bugs.

Absence-of-errors fallacy

If there are no errors in your software at all it doesn’t mean it’s successful. Detecting and resolving bugs doesn’t work if the software created is worthless and doesn’t meet the customers’ needs & demands.

Defect clustering

Defect Clustering means that a little number of modules cover most of the bugs. This is the implementation of the Pareto rule to software testing: about 80% of the errors are detected in 20% of the modules.

Exhaustive testing is impossible

It is impossible to test all mixes of data, scenarios, and the requirement inside an application. The requirement is the optimal number of testing based on the risk assessment of the application.

Testing is context-dependent

Depending on their purpose or industry, different applications should be tested differently. The method you test a car’s autopilot varies from the way you test a website for a store. All the software is not equal.

Quality Assurance

As we already know Software Quality Assurance this is an engineering process that guarantees quality.

Software Quality Assurance contains the complete software development life cycle and the aim is to guarantee that the development and support processes are continuously improved to provide products that fit the standard.

Once the processes have been established and realized, Quality Assurance is in charge of classifying defects in the processes and improving those flaws to regularly update the processes.

3 basic Quality Assurance responsibilities:

  • Technology transfer

    This procedure involves getting a product design document as well as the trial and error data and its evaluation. The documents are distributed, checked and approved.

  • Validation

    Here, the validation master plan for the entire system is prepared, approval of test criteria for validating product and process is set, and resource planning for the execution of a validation plan is done.

  • Documentation

    This function controls the distribution and archiving of documents. Any change in a document is made by adopting the proper change control procedure. Approval of all types of documents is finalized.
