BIS has a team of QA professionals with over 32,000
hours of external QA experience. We have well educated specialists
who perform a system analysis beyond basic testing which allows for
discovery of the system's weak points. In the most difficult cases,
the testing is performed by our top developers who solve tasks of
utmost complexity according to client's needs.
To guarantee the effectiveness and thoroughness of the testing, BIS
QA team uses the most up-to-date technologies. Some of the techniques
we use to assure the system’s proper functionality include:
|
| Black-box (Functional) Testing |
| Black-box testing implies that the tester only knows
the input and the expected outcome but doesn't how the program works.
During this process, the tester does not examine the programming code
and does not need any further knowledge of the program other than
its specifications. This is the most common and simple type of testing
and is often performed externally.
Being fairly simple, it has several important advantages: |
 |
The test is unbiased because the developer
and the tester are independent from each other. |
|
The test is done from the user point of view,
not that of the developer. |
|
Test cases can be designed as soon as the specifications
are complete. |
|
| White-box Testing |
| White-box testing implies knowledge
of the program and familiarity with the code. The data for this testing
is carefully chosen and requires more skillful testers. |
| Performance Testing (including
profiling and benchmarking) |
| This type of testing is yet more complicated.
If conducted by specialists, it can show not only whether the system's
performance conforms to the specifications, but also determine potential
bottle-necks and improvements for parts of the code that are crucial
for the system's performance. |
| Configuration testing (different
platforms, operation systems, browsers) |
| BIS is skilled in testing application
developed for any platform, including Windows, the UNIX-family, and
Mac OS. |
| Stress Testing |
| BIS checks to see how the system works
with a maximum specified load and stress. |
| Automated Testing |
|
Testing process can be greatly accelerated and facilitated
with the use of automation. Much of the routine can repeatedly tested
by the machine, which saves a lot of time and effort.
We use MQC (Mercury Quality Center) for automation purposes.
