Understanding Dynamic Testing

Dynamic testing refers to evaluating the dynamic behavior of code within a software application. Compiling and executing the software code is essential during this process. 

Dynamic testing and static testing serve different purposes in the software testing lifecycle.  

• Execution: Dynamic testing requires code execution, whereas static testing is conducted without running the software.  
• Test сases: Dynamic testing involves test cases, while static testing does not.  
• Process: Dynamic testing is active and focuses on validation, while static testing is passive and primarily concerned with verification.  
• Tools: Dynamic testing is often automated using tools, while static testing is usually performed manually.  

Dynamic testing helps uncover errors that may not be visible through static analysis. It is beneficial for testing integration scenarios, performance, and component interactions. Incorporating dynamic testing in software testing into development practices enables organizations to cultivate a continuous enhancement culture, ensuring that each iteration delivers top-notch software while maintaining flexibility and efficiency.   

Distinguishing Features of Dynamic Testing

Familiarize yourself with the distinguishing features to understand the basics and principles of dynamic testing in software testing. Here are some of them:   

• Dynamic software testing involves running and assessing software applications against a predetermined set of test cases during the testing process.   
• The initial step involves identifying the specific feature requiring testing. Afterward, executing the test case in a test environment becomes crucial. Early preparation of the test case is pivotal in dynamic software testing.   
• Executing the code with appropriate inputs as per end-user requirements is significant.   
• It is obligatory to analyze the actual outputs after the test execution and compare them with the expected outputs. The obtained output aids in determining the software application's behavior and functionality. Test results indicate compliance or failure.   
• It is a structured testing method for various testing functions such as test execution, coverage consideration, reporting, and test case identification.  

Dynamic testing practices within the Software Testing Life Cycle (STLC) encompass essential tasks. These include analyzing test requirements, formulating testing plans, designing and implementing tests, establishing the testing environment, executing tests, documenting defects, and concluding tests. Successfully executing each task in dynamic testing hinges on completing the preceding task within the framework.  

In the STLC framework, the initiation of dynamic testing corresponds with the development of test cases. Let's explore each step in more detail.  

Dynamic Testing Strategy

Let us delineate the strategy to be adhered to for dynamic testing.  

1. Test сase design and implementation: During the initial phase of dynamic testing, test cases are developed based on predefined project requirements and the testing scope. This phase involves establishing test conditions, deriving test cases, defining coverage items, and identifying the features that need to be tested.  
2. Test environment setup: Ensure the testing environment closely mirrors the production setting. This phase includes configuring the build and managing the test platforms.  
3. Test execution: Executing the test cases transpires during this phase.  
4. Bug reporting: If the test results differ from the expected outcomes, mark the test case as failed and log the identified defect. 

This approach ensures a comprehensive evaluation and yields dependable outcomes throughout the dynamic testing process.

Dynamic Testing Types

Dynamic software testing involves executing the code in the runtime environment to validate the functionality and performance of the software application. This validation approach includes both functional and non-functional tests. Below are the primary types of dynamic software testing explained in detail:   

Functional Testing   

Functional testing focuses on verifying the software application's specifications to ensure proper functionality. It assesses the developed features of software applications to confirm they align with the requirement specification. Functional testing is conducted by executing test cases prepared by the QA team. Each software application module is tested during this stage by providing inputs and validating the corresponding outputs.   

Functional testing is further categorized into the following types: 

• Unit Testing focuses on individual components or modules to verify their functionality in isolation, ensuring each unit operates independently.    
• Integration Testing examines the interaction between different software application components to guarantee seamless collaboration. It evaluates how components function and interact with each other. (You can also explore our article software integration testing for comprehensive insights).  
• System Testing validates the entire software system, including its integrations with external systems or dependencies. It assesses all software application components and modules to ensure they satisfy business requirements.    
• Acceptance Testing ensures that the software complies with specified requirements and meets end-users' needs. This test is crucial before releasing the software application to ensure optimal performance under real-user conditions.   

Non-Functional Testing 

Non-functional testing is a process that focuses on validating the quality of software applications by examining their non-functional aspects. Conducting non-functional tests helps mitigate production risks associated with non-functional aspects of software applications. Non-functional testing is integrated into various stages of the testing cycle, spanning all test levels.   

• Performance testing assesses how the software performs under various conditions, including load and stress scenarios. For example, dynamic testing often involves performance testing to ensure the software effectively handles expected user loads.    
• Usability testing assesses the software's ease of use and intuitiveness. It ensures that the interface and user experience meet user needs and expectations. Interested in improving user experience? Check out our guide on how to conduct usability testing for practical tips and best practices.   
• Security testing identifies vulnerabilities and ensures that the software is protected against threats and attacks. It can be tested dynamically by simulating potential security breaches.  
• Compatibility testing checks how well the software operates across different devices, browsers, and operating systems.  

These non-functional testing types complement dynamic testing by addressing different performance aspects and ensuring a comprehensive software evaluation.

Understanding these methods facilitates comprehension of the strategies employed in dynamic software testing procedures. The primary dynamic testing include several types of testing techniques. Let us delve into a comprehensive exploration of each approach:  

Black Box Testing  

Black box testing entails validating software applications without delving into their internal structure, code, or design details. This form of testing focuses on verifying the software's functions and executing the complete test suite without programming expertise. Test scenarios are meticulously considered in alignment with given requirements and specifications. 

Consequently, software applications are assessed from an end-user perspective without insights into their internal workings.  

White Box Testing  

White box testing, or clear box or structural testing, involves scrutinizing software applications' internal structure and code. This form of testing necessitates coding proficiency as it involves assessing the internal code implementation and algorithms. Testers possessing access to the underlying code craft test cases focusing on specific code paths, logic branches, and conditions.  

This testing methodology mandates a meticulous examination of the programming, line by line, to identify related errors.  

Grey Box Testing  

Grey box testing amalgamates black box and white box testing principles. Testers undertaking grey box testing possess partial knowledge of the software's internal mechanisms. This partial knowledge may include insights into system documentation, database schemas, or limited comprehension of the code structure. Leveraging this partial understanding, test cases are formulated to gauge the software's behavior and operational capabilities.  

This comprehensive approach helps identify defects arising from interactions between diverse system components or modules. Explore our article, grey box penetration testing, to gain insights into effective security testing strategies.

Illustration of Dynamic Testing

Equipped with knowledge of dynamic testing and its characteristics, let's delve into an example prepared by our testers for a more detailed illustration of this concept.  

In this case, we will examine the login functionality of an application like www.x.com.  

For instance, if we intend to create a new account with a strong password, we must adhere to predefined criteria in the password field. Specifically, the password must be eight characters long, include capital letters, and contain at least one unique character.   

During testing, we would assess all input conditions related to this feature and confirm the resulting output. Furthermore, we can introduce non-compliant conditions, like entering a 4-character password, to check whether an error occurs.  

Difference Between Static and Dynamic Testing

Various testing activities and techniques are used in testing software to ensure it performs as expected. All testing activities and techniques can be classified as either static or dynamic testing, and they are complementary to each other as they tend to find defects/failures effectively and efficiently.  

Static testing is the testing of software or its components at the specification or implementation level without executing the software; it is a powerful way of improving the quality and productivity of software development. The table below shows a comparison of the testing approaches. 

Static and dynamic testing are essential methods for ensuring software quality, each with unique strengths in defect detection and efficiency. While static testing is cost-effective and focuses on verification without execution, dynamic testing involves validation through code execution, often at a higher cost.
