It's self-evident that software development and testing are bound. Both these activities are directed at producing high-quality software product. But while working on an application these two branches should be independent.

Experts in web site testing, desktop testing and mobile application testing believe that that they cannot perform their work properly if they are subordinate to the development team manager.

The Point is That Test Reports, Comments and Judgments Must Be:

- clear;

- informative;

- impartial.

This can be achieved only when an independent software testing company is involved in the project. In this case the development team managers will not be able to influence the test results and estimation of the product. Otherwise test engineers will have to obey orders from above in the prejudice of the application quality.

Testers will Have to Adjust Their Reports and Conclusions in Order To:

- make their reports and assessments comply with and opinions of the developers;

- to please certain project managers and allow them to achieve their vain goals, for example, to release the product up to a certain date.

Under such conditions testers cannot be objective and are unable to influence the development process.

Situation of that kind lead to poor software testing and, as a result, release of a low quality program that will likely fail in production as the users are not inclined to tolerate functional, usability or other errors. Nowadays there is a wide choice of various software products; the users choose the best ones.

Competition at the modern market of software products and risk of considerable money losses make project managers refuse software testing derogation.

There is a practice of employing an audit company to watch the development and quality assurance processes. Solutions of that kind create favorable conditions for independent and objective manual and automated testing and evaluation of the software. No project manager can influence testers' reports and conclusions.

So, when testers are independent and impartial, the software development life cycle may take more time and resources than the management assumes, but the constructed system be successful in production.

The Main Advantages of Independent Testing Team Are:

- objective test reports and comments on the software;

- responsibility of the testers for the reported errors and quality of the program in general;

- in most cases saving of time and efforts required for the software development process;

- the end-users are satisfied with the product.

A professional software testing company is always independent and impartial in its reports and evaluation of the product. So, it is preferable to trust mobile testing, desktop testing and web site testing to such an institution.
