Concurrency testing is mainly used to check the performance of a website when there are multiple users active on your website. That’s why it is also called as Multi-User Testing. Synchronization testing is like a step to get a website’s traffic ready, So that it doesn’t get stuck when there are multiple users. In other words, we can say monitoring the effect while multiple users take the same action at the same time.
Concurrency test techniques :
- Code review : In this process, the embedded code and its structures are verified. This is a time-consuming process.
- Static Analysis : Static analysis is used to check and evaluate the coding system before the code is executed. It is useful for discovering errors and errors in the system.
- Fuzz Test : In this test, the user feeds incorrect random data and then waits to see how the program responds. There is no logic behind the fuzz test, it is more than just a guess as the bad data is provided to crash the program.
- Con Test : Contest removes sync errors in multi-threaded Java applet. The competition also points out shortcomings in the unit test.
- Reachability testing : Usually, reachability testing is not possible for many applications because it requires large subtests.
- Random Test : The coverage area is increased by randomizing the test inputs. Multiple strands are tested simultaneously. For better results, 5-10 strandsshould be tested each time.
- Concurrent Test Extension : This can be used to test multi-threaded or concurrent software. This type of test is easily extendable and consumable using permutation algorithms. Without extension, the combination test is effective for the serial program test.
Advantages :
- Issues like data corruption and dead lock are easily identified.
- Encapsulation makes it easy to check behavior of a certain portion of a program.
- Reliability and durability of the software product increases.
