Below are recommendations on how to achieve goals established regarding the analysis of an identified error:
Determine Сritical Moment
On finding error, the tester can only determine its symptom, but he actually does not know what caused this error. The program starts to behave unexpectedly due to a bug in its source code, which is not at the tester’s disposal. And this error may occur not necessarily in the program’s part where its effects were seen, but much earlier and in another piece of the code. If you identify the moment at which it actually happened, it will help the programmer locate and repair any errors found.
Software testing services companies are looking forward to providing you with the most accurate information about your products’ quality and helping to improve it if necessary.
When executing every step towards reproducing an error, you should carefully monitor the behavior of the program, trying to observe any deviation from the norm, the slightest indication that something is going wrong. Such minor software product anomalies are easy to overlook or ignore, and yet, they can be the first symptoms of the errors being analyzed by you.
The Error Symptoms May Be As Follows:
Error Messages. Find out exactly at what point error message appears, try to understand why it happens, and check it against the list of error messages that are listed in the documentation of the program. Software testing lab is appropriately equipped to run all types of tests that help to identify various software errors as well as their causes.
Delays In Data Processing. If it takes so long for the program to display the information on the screen or perform some operations, this may mean that something is going wrong with it. The software can execute irrelevant subprograms, incorrectly handle the data, etc. Therefore, you should always pay attention to the suspiciously long delays and carefully check the resulting data.
Screen Flashing / Refreshing Issues. If the screen suddenly flickers, it may mean that it has been updated by an error handling routine. This may be the first thing the program will do so that only correct information can be displayed on the screen, and the rest of its activities may occur later or not to occur at all.
