Dynamic Testing Techniques
Dynamic testing employs various techniques to analyze and evaluate the software’s behavior when running. Some common dynamic testing techniques include:
- Black-box testing: This technique tests the software’s functionality without delving into the internal workings of the software. The tester inputs the data and checks if the output is as expected.
- White-box testing: This technique tests the software’s internal implementation details. The tester tests specific functions, methods, or code snippets to ensure they work as expected. Get to know key differences between Blackbox Testing and White Box testing
- Grey-box testing: Grey-box testing is a combination of black-box and white-box testing. In this technique, the tester has partial knowledge of the internal workings of the software, which helps to create more comprehensive test cases.
- Regression testing: We perform regression testing when we add new features to existing software. It ensures that changes in the software do not impact existing features negatively.
- Performance testing: Performance testing evaluates the software’s response time, load capacity, and stability under heavy usage to ensure it can handle real-world situations.
- Security testing: Security testing ensures the software is safe and secure from malicious attacks, including data breaches, unauthorized access, and hacking attempts.
These dynamic testing techniques help testers to assess software behavior and identify issues or defects that can compromise the software’s functionality, reliability, or security.
Dynamic Testing and Test Automation
Test automation should be considered for dynamic testing in the following scenarios:
1. Repetitive and frequent execution: If a particular test scenario or set of test cases needs to be executed repeatedly and frequently, test automation can save time and effort by automating the execution process.
2. Large and complex test suites: When dealing with a large number of test cases or complex test suites, manual execution becomes time-consuming and prone to human errors. Automation can efficiently handle the execution, reducing manual effort and ensuring consistent results.
3. Regression testing: Regression testing involves retesting the software after modifications or enhancements. Since regression testing often requires executing a significant number of test cases, automating this process helps in detecting any regression issues quickly and efficiently.
4. Performance testing and load testing: These types of testing involve simulating multiple users or high workloads. Automating the execution and analysis of performance tests helps in accurately measuring the system’s performance, identifying bottlenecks, and collecting performance-related metrics.
5. Cross-platform and compatibility testing: When testing software across different platforms, operating systems, browsers, or devices, test automation simplifies the process by allowing parallel execution on multiple
6. Data-driven testing: If the test cases require variations in input data sets, automating data-driven testing can enable the efficient execution of multiple test scenarios with different data combinations.
7. Integration testing: In scenarios where the software interacts with various external systems or components, automating integration testing helps in simulating and verifying interactions, ensuring proper integration and functionality.
It is important to note that not all dynamic testing scenarios are suitable for automation. Some aspects, such as exploratory testing or user experience testing, may require human judgment and observation. Test automation should be applied judiciously based on factors like test complexity, repeatability, and ROI considerations.

Continuous monitoring, analysis, and adaptation of the testing approach may be necessary based on the test results and evolving requirements.
Example of Dynamic Testing
Let’s consider a scenario where we are checking the login process by entering valid and invalid credentials to ensure successful authentication and appropriate error handling.
Scenario: Testing the Login Functionality
Test Objective: To ensure that users can successfully log-in to the web application using valid credentials.
- Enter a valid username and password.
- Click the “Login” button.
- Verify if the user is redirected to the home page.
- Check if the appropriate user-specific content is displayed.
- Log out and repeat the steps with an invalid username/password combination.
Expected Outcome: The login should succeed for valid credentials, redirecting the user to the home page with the correct content. For invalid credentials, an error message should be displayed, preventing access to the system.
We can discuss another example of testing the file upload feature by uploading a file, verifying successful storage and metadata display, and checking error handling for unsupported file formats.
Scenario: Testing the file upload feature of a document management system.
Test Objective: To ensure that users can successfully upload a valid document/file onto the document management system.
- Select a file to upload.
- Click the “Upload” button.
- Verify if the file is successfully uploaded and stored in the system.
- Confirm that the file metadata (name, size, date) is displayed accurately.
- Attempt to upload a file of an unsupported format.
Expected Outcome: The file should upload successfully, and the system should store it correctly with accurate metadata. Unsupported file formats should generate an error message, preventing the upload.
During the dynamic testing of the login functionality, testers would be actively interacting with the application, executing the steps, and verifying its behavior in real-time. The process helps uncover any issues or deviations from the expected behavior, such as incorrect login, error messages, or improper redirection. Defects found during dynamic testing can then be reported, analyzed, and addressed by the development team.

This helps validate the software’s usability, responsiveness, and compatibility across various platforms or devices.
4. Improved reliability: Potential failures or defects can be identified early in the development process by subjecting the software to dynamic testing. This improves reliability as issues are addressed promptly, reducing the likelihood of critical failures or system crashes in production environments.
5. Enhanced security: Dynamic testing also helps identify vulnerabilities and weaknesses in the software, allowing for robust security measures to protect against potential threats and breaches.
1. Time-consuming: Dynamic testing requires the creation and execution of test cases, which can be time-consuming, especially for complex software systems.
3. Expensive: Dynamic testing often requires specialized tools and resources to execute test cases effectively. These tools can be expensive to acquire and maintain, especially for organizations with limited budgets or small-scale projects. Additionally, dynamic testing may require skilled testers proficient in using these tools, further adding to the overall cost.
4. Dependent: Dynamic testing tools rely on the current state of the system being tested, making it necessary to update and adapt the tools as the system evolves, which can be time-consuming and resource-intensive.
Types of Dynamic Testing
There are many types of dynamic testing, all of which come under two categories: white box testing and black box testing.
White Box Testing
White box testing is a software testing technique that focuses on examining the software’s internal structure, design, and implementation details. Developers perform white box testing because it requires access to the software’s internal code, data structures, and algorithms. Its primary objective is to uncover coding errors, logic flaws, and missing functionality within the software.
Dynamic testing when done as a part of white box testing, deals with identifying and testing the paths through which data is transferred and transformed within a program. It aims to reveal potential errors or anomalies related to the flow of data, such as incorrect assignments, missing data updates, and data dependencies.
Black Box Testing
Black box testing is just the opposite of the white box, where testers do not have access to the knowledge of the internal structure of the software. In black box testing, the tester treats the software as a “black box” and tests it solely based on its inputs and expected outputs without considering the internal workings. This approach helps validate whether the software or system behaves as expected, meets the specified requirements, and correctly handles various inputs and scenarios. There are two types of black box testing;
As the term suggests, functional testing checks the functionality of the software against the specification documents. It focuses on how the application is behaving on the front end rather than giving attention to the actual code. There are four levels of functional testing that you should know about:
Unit Testing: This is the first level. Developers perform unit testing to check every unit/snippet of code before moving ahead for further testing or development. It is the first level of testing that focuses on the accuracy of the code and validates the unit components.
Integration Testing: This testing verifies the interaction between two or more modules of the same system. It tests the transfer of data and compatibility between the modules. This is the second level.
System Testing: System testing refers to validating the entire system as a whole, ensuring that all components and subsystems work together correctly. It checks the system against functional and non-functional requirements, including reliability, performance, usability, and compatibility. This is the third level.
UAT: User acceptance testing (UAT) is the phase of testing where end users validate and approve the software to ensure it meets their requirements and is ready for production. Users perform real-world scenarios to determine if the software functions as expected and meets their needs. It is the fourth and last level before releasing the software.
Non-functional testing focuses on evaluating the non-functional aspects of a system, such as its performance, reliability, usability, scalability, security, and maintainability. Unlike functional testing, which verifies the specific functionality of the software, non-functional testing assesses its quality attributes and how well it performs under various conditions and constraints. The goal is to ensure that the software meets the desired non-functional requirements and provides a satisfactory user experience.
Non-functional testing is further divided into various types, which represent different testing levels:
Performance testing: It checks for how well the software is performing under certain traffic loads. Performance testing evaluates a software system’s speed, scalability, and responsiveness under different loads and conditions. One example can be simulating multiple users accessing a website simultaneously to measure its response time and server performance.
Usability testing: Usability testing assesses a software or system’s ease of use and user-friendliness by observing users’ interactions and collecting feedback. An example of this could be observing users as they navigate through a mobile application to evaluate the intuitiveness of the user interface, menu navigation, and overall user experience.
Compatibility testing: Compatibility testing verifies the compatibility of a system or application across different platforms, operating systems, browsers, and devices. It ensures that the software functions correctly and displays consistently across various configurations, avoiding interoperability and user experience issues.
Recovery testing: This testing checks how effectively a system recovers from a crash or downtime. It assesses the system’s ability to restore data integrity, resume normal operations, and recover gracefully from unexpected events or disasters, ensuring business continuity and minimizing downtime.
Security testing: Security testing focuses on identifying vulnerabilities and weaknesses in a system’s security controls. It uncovers potential threats, assesses the system’s ability to protect sensitive data, and verifies compliance with security standards, thereby ensuring the software’s integrity, confidentiality, and availability.
