Effectiveness of software testing techniques in enterprise: a case study

Figure 6. The trends of testing techniques used in R&D teams 
Prepared by author according to empirical research results. 
The experts' answers revealed that all teams are using regression testing to ensure the reliability 
of each software release. The second and third popular techniques are functional testing and non 
functional testing. Each of them are tended to discover specific types of defects. Further, performance 
development, and acceptance testing techniques are selected. Experts from Team 2 and Team 3 have 
chosen acceptance testing. The Expert B added a comment 
"Our team is not using this technique 
directly, but other team is doing acceptance testing for our team".
So we got new relevant information. 
Whereas, some experts mentioned additional testing techniques that were not added in a list. Expert A 
stated that his team uses 
"Integration testing"
as well. Expert G added 
"Exploratory and smoke 
testing"
.
Furthermore, we sought to identify what static analysis techniques are used in teams. Thus, the 
most used technique is Code or Design Inspection (see Figure 7, page 53). Second and third place 
belong to and Review (peer) and Review (technical) respectively. According to research results, 
Review (management) and Walk-through are not used at all.
