Software Testing Services: Race Conditions & Error Prediction
By running a “standard” test of the program, using low-speed test equipment, or under heavily increased load, you can face completely unexpected race conditions. And if it turns out that the program is sensitive to such situations, then, under such circumstances, it will be necessary to completely test the software application. Do not even succumb to the persuasions of the project manager who says that you are wasting your time performing inappropriate tests and that the users will never run the program in a similar fashion. It is false as they will do this for certain! Users will run this software on cheap low-power computers. Even on those computers, they will be running programs in parallel, at that these will be large programs. Therefore, your task is to ensure the reliability of the developed software so that it can work as expected, albeit slowly, but without crashing in any operating system and under any additional loads. And at least, you need to figure out exactly which of your setup files are not compatible with this software product.
Any software app user wants to have a reliable software program. But it happens that this digital product starts showing incorrect behavior. To identify the cause of this failure and ensure desirable performance of the app people tend to use software testing services.
If it turns out that the performance of the software is clearly unsatisfactory in a specific hardware and software environment, and in this environment it will be run by some users at least, it is required to draw up a separate report on this issue. It is best to enter the report into the database on the next day, so that it can be stored in isolation from the reports on the crashes that happen at higher loads or when the program is run on too slow speed machine. So this report will probably get more attention from the project manager than when it is reviewed together with other similar, but much less important reports.
Software apps are subjected to load testing to determine how well they respond to various levels of usage. This type of verification is a core competence of load testing companies.
Sometimes a tester assumes that a particular test class will cause the program to fail, although he cannot prove his argument. Trust your intuition and be sure to include such tests in the overall plan. There are a number of conditions and values, which, although are not boundary ones, but often cause software failures. A typical example of such values is ZERO. Do not waste time trying to find rational justifications for why a particular input value or part of the program seems suspicious to you. Just test it.
It happens that in difficult situations intuition suggests a much better testing tactics than trivial logic does. Sometimes associative relationship helps: you have already found an error under the same circumstances, although you cannot even remember doing that. Whatever it was, trust your gut feeling and learn to listen to it: with experience you will get more reliable ‘gut feeling’ level of understanding.
Mobile app testing companies are the organizations that deal with mobile apps developed for handheld devices, testing them for usability, reliability, functionality and consistency.
