Software Testing Companies and The Challenges They Face at Work Day By Day
Multi-user and multi-tasking
If your product is a complex multi-tasking or multi-user system, it will be much more difficult to test it. It is necessary to check whether or not the product can perform several tasks simultaneously and how it coordinates actions of multiple users. A typical example of such system is a multiuser database management system, where several users sitting at different and, perhaps, even quite remote computers can simultaneously enter data in the same table. To test such system software testing companies have to put it to work in real world conditions, involve a lot of people in the work using lots of technical equipment items and possibly write special programs that simulate one-time data entry. A more detailed discussion of this issue can be found in the book by Beyzer, 1984.
The program should properly respond to the wrong or irregular, or undocumented user activities. Try to make as many mistakes as you can and you will be able to see each message described in the documentation with your own eyes. Maybe you will encounter error messages that are not documented. Through such testing, you will find the largest number of errors, as this part of the program usually receives the least attention.
By the way, penetration testing companies are in rush to identify security problems in your IT systems so that no attacker can harm your network.
Compatibility and conversion of data formats
Two software products are consistent (compatible), if they can work with the same data files, or if they co-exist safely in the computer’s memory and work without interfering with each other. Therefore, when instructed to check out the compatibility of the program, you should be sure to find out what kind of compatibility is at stake.
If the two programs cannot work directly with the data to each other, it does not mean yet that they are totally incompatible. It is possible that users can take advantage of special converters – proxies that convert data from one format to another.
One of the most common situations that require data conversion is the release of a new version of the program. In this case, the new program should be able to determine that the proposed data are stored in the format compatible with the previous version and perform their conversion independently.
