What is Dynamic Testing?
Definition: Dynamic testing is a type of software testing that involves executing the code of a software application and evaluating the behavior of the application while it is running. It is also known as “running the code” or “execution-based testing.”
Dynamic testing in software testing is used to verify that the software application is working as intended and is able to handle various input and output scenarios. It is typically performed after the software application has been developed and compiled, and is often used in combination with other types of testing, such as unit testing or integration testing.
Dynamic testing may involve testing the software application manually, or it may involve using automated testing tools to execute the tests. It is an important step in the software development process, as it helps to ensure that the software application is of high quality and is able to meet the needs of the users.
How To Do Dynamic Testing ?
Dynamic testing is done by executing the software under test and evaluating its behavior and performance under different conditions. Here are the general steps involved in conducting dynamic testing:
1.Test planning: Identify the test objectives, requirements, and scope of the testing effort. Develop a test plan that outlines the testing approach, resources, and timelines.
2.Test case design: Create test cases that cover various scenarios and inputs that the software may encounter. Test cases should design to validate the functionality, performance, security, and usability aspects of the software.
3.Test execution: Execute the test cases and record the results. This can do manually by a tester or using automated testing tools.
4.Defect reporting: Report any defects or issues discovered during the testing process. Defects should be clearly documented, including the steps to reproduce the issue, the expected and actual results, and the severity of the issue.
5.Retesting: After defects fixed, the affected test cases should re-executed to verify that the issues have resolved.
6.Test closure: After all the test cases execute and the results have been analyzed, the testing effort is concluded. A final report create that summarizes the testing results and highlights any outstanding issues.
Types of Dynamic Testing
There are several types of dynamic testing which are shown below:
Functional testing
This type of testing use to ensure that the software meets the functional requirements specified in the requirements documentation. Functional testing can perform manually or using automated testing tools, and typically involves creating test cases that cover various scenarios and input data.
Performance testing
This type of testing use to evaluate how the software performs under different levels of load and stress. Performance testing can conduct using a variety of tools and techniques, including load testing, stress testing, and endurance testing.
Security testing
This type of testing use to identify security vulnerabilities in the software. Security testing can include a variety of techniques, such as penetration testing, vulnerability scanning, and code analysis.
Usability testing
This type of testing use to evaluate the usability and user-friendliness of the software. Usability testing typically involves observing users as they interact with the software and gathering feedback on their experience.
Compatibility testing
This type of testing use to ensure that the software functions correctly on different hardware and software platforms. Compatibility testing can involve testing the software on different operating systems, browsers, and hardware configurations.
Regression testing
This type of testing use to ensure that changes to the software have not introduced new defects or caused existing functionality to break. Regression testing typically involves re-executing previously tested test cases to verify that they still function correctly after changes have been made to the software.
Dynamic Testing Techniques
Black box testing: This technique involves testing the software without any knowledge of its internal workings. Testers only have access to the software interface and evaluate its behavior based on various inputs and expected outputs.
White box testing: This technique involves testing the software with knowledge of its internal workings. Testers can examine the source code, design documents, and other technical documentation to evaluate the software’s behavior and performance.
Grey box testing: This technique is a combination of black box and white box testing. Testers have limited knowledge of the software’s internal workings and evaluate its behavior based on both input and output data as well as knowledge of the system’s internal design.
Boundary value analysis: This technique involves testing the software using input data that is at or near the boundary values of its input range. This technique used to identify issues related to input data validation, such as data entry errors or buffer overflow vulnerabilities.
Equivalence partitioning: This technique involves dividing the input data into equivalence classes based on their behavior or output. Test cases designed to test each equivalence class to ensure that the software handles different input data scenarios correctly.
Random testing: This technique involves generating random input data to test the software’s behavior and performance. Random testing is useful for identifying defects that may not detected through structured testing approaches.
Exploratory testing: This technique involves testing the software through exploration and discovery, without the use of predefined test cases. Testers explore the software interface and functionality to identify defects and issues.

Advantages Of Dynamic Testing
Some advantages of dynamic testing include:
Real-world evaluation: Dynamic testing allows for the evaluation of software behavior in real-world conditions, allowing testers to identify issues that may not be apparent during static testing.
Early defect identification: Dynamic testing can identify defects and issues early in the software development process, allowing for earlier remediation and cost savings.
Improved software quality: Dynamic testing can help improve software quality by identifying and addressing defects and issues before the software released to users.
Greater confidence in software: Dynamic testing can help increase confidence in the software by demonstrating that it meets its requirements and operates as expected.
Disadvantages Of Dynamic Testing
Some disadvantages of dynamic testing include:
Time-consuming: Dynamic testing can be time-consuming, especially when executed manually, as it requires executing test cases and analyzing results.
Limited test coverage: Dynamic testing can only test for the scenarios and inputs that are explicitly specified in the test cases. It is possible that some scenarios or inputs may miss, leading to potential issues in the software.
Costly: Dynamic testing can be costly, especially when using specialized tools or requiring a significant amount of time and resources.
Testing bias: Dynamic testing can bias towards testing scenarios and inputs that are more likely to occur in real-world conditions, potentially overlooking edge cases or less likely scenarios.
Dynamic Testing Example
Here is an dynamic testing example:
Let’s say you are testing a web application that allows users to sign up for an account, log in, and post comments on a forum. Here is an example of a dynamic testing scenario:
Functional testing: You create test cases to ensure that users can sign up for an account, log in, and post comments on the forum. You also test for scenarios such as incorrect login credentials, validation of input data, and error handling.
Performance testing: You use a performance testing tool to simulate different levels of user traffic on the website and evaluate its response time, page load time, and other performance metrics. You also test for scenarios such as high traffic loads or concurrent users.
Security testing: You use security testing tools to identify potential security vulnerabilities in the application, such as SQL injection or cross-site scripting. You also test for scenarios such as invalid input data, user authentication, and data encryption.
Usability testing: You observe users as they interact with the application and gather feedback on their experience, such as ease of navigation, clarity of instructions, and overall user-friendliness.
Compatibility testing: You test the application on different browsers, operating systems, and hardware configurations to ensure that it functions correctly on different platforms.
Regression testing: You re-test previously tested functionality to ensure that changes to the application have not introduced new defects or caused existing functionality to break.
