Software Testing | Dynamic Testing

INTRODUCTION 

1. Dynamic testing is a type of software testing that involves executing the software and evaluating its behavior during runtime. It is also known as functional testing, as it focuses on testing the software’s functionality and how it behaves under different inputs and conditions.
2. During dynamic testing, the software is run and tested against a set of predefined test cases. These test cases are designed to cover a range of inputs and use cases, and they are used to check the software’s behavior and output in response to different inputs. This can include testing the software’s user interface, functional requirements, and performance.
3. Dynamic testing can be performed manually or through the use of automated testing tools. Automated testing tools can be used to run test cases repeatedly and quickly, making it easier to identify and fix any issues that are found.
4. Dynamic testing is an important part of the software development process, as it helps to ensure that the software is working as intended and meets the requirements of the end users. It also helps to identify and fix any bugs or issues that may not have been identified during the earlier stages of development.

It is important to note that dynamic testing is just one aspect of software testing, other types of testing like Unit testing, Integration testing, System testing, and Acceptance testing are also important and should be performed in addition to dynamic testing.

Dynamic Testing is a type of Software Testing which is performed to analyze the dynamic behavior of the code. It includes the testing of the software for the input values and output values that are analyzed. Dynamic Testing is basically performed to describe the dynamic behavior of code. It refers to the observation of the physical response from the system to variables that are not constant and change with time. To perform dynamic testing the software should be compiled and run. It includes working with the software by giving input values and checking if the output is as expected by executing particular test cases which can be done with either manually or with automation process. In 2 V’s i.e., Verification and Validation, Validation is Dynamic Testing.

Levels of Dynamic Testing

There are various levels of Dynamic Testing. They are:

• Unit Testing
• Integration Testing
• System Testing
• Acceptance Testing

There are several levels of dynamic testing that are commonly used in the software development process, including:

1. Unit testing: Unit testing is the process of testing individual software components or “units” of code to ensure that they are working as intended. Unit tests are typically small and focus on testing a specific feature or behavior of the software.
2. Integration testing: Integration testing is the process of testing how different components of the software work together. This level of testing typically involves testing the interactions between different units of code, and how they function when integrated into the overall system.
3. System testing: System testing is the process of testing the entire software system to ensure that it meets the specified requirements and is working as intended. This level of testing typically involves testing the software’s functionality, performance, and usability.
4. Acceptance testing: Acceptance testing is the final stage of dynamic testing, which is done to ensure that the software meets the needs of the end-users and is ready for release. This level of testing typically involves testing the software’s functionality and usability from the perspective of the end-user.
5. Performance testing: Performance testing is a type of dynamic testing that is focused on evaluating the performance of a software system under a specific workload. This can include testing how the system behaves under heavy loads, how it handles a large number of users, and how it responds to different inputs and conditions.
6. Security testing: Security testing is a type of dynamic testing that is focused on identifying and evaluating the security risks associated with a software system. This can include testing how the system responds to different types of security threats, such as hacking attempts, and evaluating the effectiveness of the system’s security features.

 
Dynamic Testing Process Phase
 
Advantages of Dynamic Testing

• It discloses very difficult and complex defects.
• It detects the defects that can’t be detected by static testing.
• It increases the quality of the software product or application being tested.
• Dynamic testing detects security threats and ensure the better secure application.
• It can be used to test the functionality of the software at the early stages of development.
• It is easy to implement and does not require any special tools or expertise.
• It can be used to test the software with different input values.
• It can be used to test the software with different data sets.
• It can be used to test the software with different user profiles.
• It can be used to test the functionality of the code.
• It can be used to test the performance of the code.
• It can be used to test the security of the code.

Disadvantages of Dynamic Testing

• It is a time consuming process as in dynamic testing whole code is executed.
• It increases the budget of the software as dynamic testing is costly.
• Dynamic testing may require more resources than static testing.
• Dynamic testing may be less effective than static testing in some cases.
• It is difficult to cover all the test scenarios.
• It is difficult to find out the root cause of the defects.

IMPORTANTS POINTS:
Some important points to keep in mind when performing dynamic testing include:

1. Defining clear and comprehensive test cases: It is important to have a clear set of test cases that cover a wide range of inputs and use cases. This will help to ensure that the software is thoroughly tested and any issues are identified and addressed.
2. Automation: Automated testing tools can be used to quickly and efficiently execute test cases, making it easier to identify and fix any issues that are found.
3. Performance testing: It’s important to evaluate the software’s performance under different loads and conditions to ensure that it can handle the expected usage and the expected number of users.
4. Security testing: It is important to identify and evaluate the security risks associated with a software system, and to ensure that the system is able to withstand different types of security threats.
5. Defect tracking: A defect tracking system should be implemented to keep track of any issues that are identified during dynamic testing, and to ensure that they are addressed and resolved in a timely manner.
6. Regular testing: It’s important to regularly perform dynamic testing throughout the software development process, to ensure that any issues are identified and addressed as soon as they arise.
7. Test-Driven Development: It’s important to design and implement test cases before the actual development starts, this approach ensures that the software meets the requirements and is thoroughly tested.
