What is Performance Testing Life Cycle?
The Performance Testing Life Cycle (PTLC) is a set of stages that development teams go through to ensure the effective performance of the software, application, website, etc. PTLC normally consists of the following phases:
Planning
The planning stage is the first step in the performance testing lifecycle. It involves identifying the objectives of the testing, defining the scope, and establishing the testing environment.
The objective of the planning stage is to identify the performance metrics that need to be measured during testing, such as response time, throughput, and resource utilization.
Entry criteria for the planning stage include a detailed test plan that outlines the testing objectives, scope, and environment. Exit criteria for this stage include a signed-off test plan and an approved testing environment.
Studies show that early performance testing can help identify and fix performance issues before they become more complex and costly to fix.
A study by the National Institute of Standards and Technology found that “the cost of fixing a defect detected during the design phase was about 15 times less than the cost of fixing the same defect in the maintenance phase.”
Test design
In the test design stage, you will create a test script that simulates real-world scenarios to measure the performance of the software. This stage also involves identifying the test scenarios and configuring test data.
It is crucial to design scenario-based scripts that accurately represent user behavior and identify critical business functions.
Entry criteria for the test design stage include a detailed test plan, an approved testing environment, and identified test scenarios. Exit criteria for this stage include reviewed and approved test scripts.
Studies show that designing effective scripts is critical to achieving reliable results. Poor test design, insufficient test coverage, and unrealistic test scenarios are the most significant contributors to unreliable testing.

Test execution
The test execution is the 3rd in the list of phases of performance testing. It involves running the test scripts and collecting performance data. It is essential to monitor the application’s performance and identify any issues that may impact the user experience. During this stage, you will identify and report defects and work with the development team to fix them.
Entry criteria for the test execution stage include reviewed and approved test scripts, a stable testing environment, and sufficient test data. Exit criteria for this stage include reviewed and approved test results and identified and reported defects.
Studies show that identifying and fixing performance issues during the testing phase can significantly reduce the risk of performance-related issues after deployment.
