Concurrency Testing In Software Testing With Example

Concurrency Testing In Software Testing with Example

What is concurrency Testing?

Concurrency testing is a testing technique performed to identify the defect in an application when a number of users are logged in at the same time and perform the same action. This is also called multi-user testing. In software testing concurrency plays a significant role, it helps in detecting and measuring the problem in system parameters as -

Response Time
Throughput
Lock
Deadlock
System crashed

Example of Concurrency Testing

A real-time example of concurrency testing is given below.

Tatkal Ticket Booking :

The best and most straightforward example of concurrent testing is Tatkal train ticket booking, where multiple users try to log in to IRCTC at the same time ie.10 and 11 with different platforms.

Concurrency Testing Tools

There is no. of concurrency testing tool available in the market some of the widest tool is given below.

Load Runner
Jmeter -we can perform concurrency testing using jmeter
Selenium

Concurrency Testing Method

To perform the concurrent testing follow the below steps.

Create Plan
Analyze the test Plan
Define the scope
Create scenarios
Create Environment
Now Execute the plan

Why do we do Concurrency Testing?

Concurrency testing helps to identify the effect of accessing the same database record when multiple users perform the same action same time.
It also helps to identify the effect of accessing the same module when multiple users perform the same action same time.
Concurrency helps improve the robustness and reliability of concurrent programs.

Advantage Concurrency Testing :

Concurrency Testing helps to check the effect on the system when multiple users perform the same action at the same time. Concurrency Testing helps in improving the robustness of concurrent programs.
Concurrency Testing is used to identify issues like deadlock, increased response time, and system crashes.

Disadvantage of Concurrency Testing :

For concurrency, testing needs to be done on multiple platforms. For concurrency, testing requires more intensive tests.
In concurrency testing, most of the defects are time-related and difficult to reproduce.
For concurrency testing creating test cases is very difficult job tester needs to interact with the developer daily basis.
While performing the concurrency testing there are chances that new errors may occur in the code.

Hope!!! The above tutorial on concurrency testing with examples is helpful for you ...
