Why Do Best Software Testing Companies Track The Program’s Actions
To better track the performance of the program, you can use a source code debugger. It will be useful for you to acquire a lot of valuable knowledge that will broaden your horizons, for example, you will be able to understand which process is currently running, how much space and how many other computer resources the app uses, if the stack is full or not, etc. Even the best software testing companies, despite their brilliant testing experience, use the debugger when working on the apps. Here are examples of errors, which can be found via the debugger.
- Certain subroutine forgets to clean the stack after working with it, and if this subprogram is executed many times, stack overflow error may occur.
- After receiving a message from another process the specified process of the program “forgets” to inform the operating system that it can free the memory allocated for the message. (Messages which are exchanged between processes – are just in-memory data structures. When creating a message an operating system allocates memory for it, and after it is received by the addressee it should get that memory back.) If the processes exchange messages extensively, then at one point, due to inaccuracy in the processes, available memory can be exhausted. You will observe this problem using the debugger, and also you will be able to identify the usurper.
These are only two examples, but they show the opportunities that are faced by the tester knowing the programming basics. But you are not recommended to spend a lot of time working with a debugger. Do not forget that your main job is to run a “black box” testing, and as far as the debugger is concerned the programmer himself can work with it.
Load testing companies can help you understand how your program works under a specific expected load. As a result, you will be able to regulate the number of concurrent connectors to the app server.
Another way to check the performance of the program is to print its screens and changes in the data files. Remember that it is always much easier to work with a sheet of paper than with the computer screen.
If the content of the screen is changing very quickly, you can try to work on the computer with slower download speed, or find some other way to slow down the work of the program – for example, to exploit it in a multiuser environment with increased load. As a result, you can sometimes witness something important; otherwise this moment will glimpse instantly on the screen and remain unnoticed.
Game testing companies hire people to play video games online and pay them for this interesting employment that is rather amusement than work.
