Software testing
TestBenefit specializes in information systems testing. We offer comprehensive software quality assurance solution that includes project documentation analysis, drawing up a testing strategy, carrying out the tests and a credible result assesment.
How to lower software production costs while increasing the quality of software?
Software testing is used not only to find defects and check the quality of software. It also allows you to reduce the software production costs and to ensure software reliability.
Testing your software and removing any bugs at an early stage of development is much more cost effective than addressing the same issue further down the project when the programme has already been installed on thousands of computers and is used by several dozen clients from different parts of the country. For instance, should the content of an entiredatabase be erased, the activities of the company using untested, faulty software would have to be limited for as long as it takes to remove the fault and recreate the database from back-up sources.
In such a case, the costs of removing the consequences of program failure are much higher than the costs of software testing.
What kind of tests do we perform?
TestBenefi offer comprehensive software quality assurance solution that includes project documentation analysis, drawing up a testing strategy, carrying out the tests and a credible result assesment.
We offer various kinds of tests that suit the individual needs of both IT companies and other companies implementing software solutions.
Some of the most commonly performed tests include:
- functional testing, is performed to verify whether all the functions of the system run correctly and are in line with the client’s requirements and business processes;
- acceptance testing, is performed to verify and confirm whether the tested system complies with the reqirements of the contract between the supplier and the receiver of software;
- regression testing,is performed in order to verify system performance after introducing changes to software as a result of bug fixing, adding new functionalities, changing the software environment (a new version of an operation system or a data base), changing a computing platform;
- documentation testing , is performed in order to identify incoherence and inconsistencies in the analytical and technical documentation and user’s documentation created in frames of the project;
- efficiency and load testing , is performed to evaluate how well the system meets the performance efficiency requirements. This is achieved through stress-testing the system in a data and user-intensive environment;
- compatibility testing, is performed to establish whether the system is compatible with external applications depending on their version and supplier, e.g. internet browsers;
- database testing, is performed in order to verify the coherence and correctness of the operations performed in the database of the tested system;
- integration testing , is performed in order to check how well the system integrates with existing and used systems. The tests focus mainly on the interfaces between the systems.
- security testing, is performed in order to identify areas of the system where the company’s or its clients’ data are not safe or where the system is vulnerable to a potential attack.
- usability testing, is performed in order to assess the functional qualities of the user interface. This includes checking the level of accessibility, ease of use, ergonomics and the level of compliance with the end user’s expectations.
What are the benefits of software testing?
The main benefits of software testing include:
- software testing lowers the costs of software production through identifying and eliminating software defects at an early stage, as opposed to the stage when the software is prepared to enter the market or is already used by clients;
- software testing allows you to avoid enormous financial losses resulting from code errors. For instance, a crash of a space rocket that causes million dollar losses may be caused by a software defect. This may be avoided thanks to testing a particular fragment of the code responsible for the failure. Although the programmer may know his programme very well, he may not be able to spot errors that an independent tester would pick up.
- the quality of offered software increases thanks to testing and bug fixing;
- the defects identified by program users (clients) have a negative effect on the software provider’s reputation and therefore affect the software sales volume. That’s why it should be a tester’s role to identify the errors, and not the client’s.
Quality is an ideal which can’t be achieved, but which we have to strive for
