Why do we need to perform stress testing?

We have to perform the stress testing when these situations occur:

During sales time, the e-commerce website may see a spike in the number of visitors on the website. If we are not able to manage the sudden traffic can result in the loss of users' interest in the website and the company might see a loss of profits. In this scenario, we have to perform stress testing to handle such irregularities.

Stress can also be performed under the following conditions:

• When the system is feeling stressed, it must display the proper error message.
• To verify that the system can work under bad circumstances as well. 
• What happens when the system is unable to respond under the risky conditions, does it occur a huge loss in profit. 
• With the help of stress testing, we can know how the system reacts in extreme conditions.

What is the Stress Testing Process?

The stress testing process contains the following steps:

1. Find the testing environment: In this step, we will figure out the network, software, and hardware configuration and tool available that helps in achieving the stress test.
2. Figure out the performance acceptance standard: After the first step, we will find the performance acceptance criteria which help in determining the metrics which are used to test the application’s performance under stress. This step also finds out the success criteria.
3. Plan and design Stress tests: In this, we have to design and plan the stress test cases, identify the test scenarios, and more. 
4. Configure the test environment: Once the stress test plan has been created, we will move to the next step where we develop the testing environment, tools, and resources that are essential to perform each approach as features and components. 
5. Implementation of test design: Once the test environment configuration is done, we will develop the stress tests resulting in the best performance. 
6. Execute tests: In this step, we will execute the step again.
