What is dynamic software testing?

The dynamic behavior of software code is tested using the software testing technique known as dynamic testing. Finding weak points in the program runtime environment and evaluating software behavior using dynamic variables or variables that are not constant are the major goals of dynamic testing. The dynamic behavior must be tested by running the code.

Examples of dynamic software testing

The login process of any program, such as Google’s gmail.com, provides the clearest illustration of this. If we were to create an account and a password for it, you would need to follow a set of guidelines.

For example, an 8-character string must have at least one special character and a capital letter.

These are only various parameters or criteria. The program should either alert the user or refuse any input that deviates from these guidelines.

As an illustration, if you were to input all the circumstances necessary to test this capability, you would then validate the results.

You would also provide invalid parameters, such as a 4-character password, and check to see if an error is raised. All of this falls under dynamic testing.

What accomplishes dynamic software testing?

The primary goal of dynamic testing is to guarantee that software functions properly. This is before, during, and after installation, resulting in a reliable program free of significant problems.

The primary goal of the dynamic test is to guarantee that the program is consistent.

Dynamic Software Testing Types

What is dynamic software testing

Dynamic Testing may be divided into two groups:

  • White Box Testing
  • Black Box Testing

White Box Testing

Is a type of software testing where the tester is aware of the internal structure and design. It’s testing’s primary goal is to evaluate the system’s performance in relation to the code. White box testers or developers with programming skills often execute it.

Black Box Testing

Black box testing is a testing technique in which the tester is not aware of the internal structure, code, or design. The primary goal of this testing is to confirm the functioning of the system being tested.

This sort of testing necessitates the execution of the whole test suite. It is mostly carried out by testers; no programming skills are required.

There are two types of black box testing:

  1. Functional Testing
  2. Non-functional Testing

Functional Testing

Functional test cases produced by the QA team are executed to ensure that all features developed adhere to the functional specifications. During the functional testing phase, the system is tested by giving input, confirming the output, and matching the actual results with the anticipated outcomes.

Non- Functional Testing

Non-functional testing is a testing approach that primarily focuses on the non-functional characteristics of the system. Such as memory leaks, performance, or resilience of the system, rather than on functional elements. All test levels include non-functional testing.

The most important Non-functional testing techniques are:

  • Compatibility testing

Compatibility testing is done to make sure the system functions properly in various settings.

  • Recovery Testing

Recovery testing is a technique to assess a system’s capacity to bounce back from breakdowns and malfunctions.

  • Security testing

Security testing is done to guarantee that the program is reliable, i.e. to make sure that only authorized users or roles are using the system.

  • Performance Testing

Performance testing is done to see if the system responds to requests in a reasonable amount of time under the required network load.

  • Usability testing

Usability testing is a technique to examine how easily people can utilize a system and how comfortable they are doing so.

Dynamic Software Testing Techniques

What is dynamic software testing

The STLC Dynamic Testing Techniques includes a variety of activities, including the analysis of test requirements, test planning, the design and implementation of test cases, the creation of test environments, the execution of test cases, the reporting of bugs, and the test closure itself.

The success of the preceding task in the testing process is a prerequisite for the completion of all tasks in dynamic testing approaches.

The approach that should be used for dynamic testing:

The resources and timing should be the major areas of attention for the test strategy. The goal of testing, the testing scope, the testing stages or cycles, the kind of environment, the assumptions or problems that could be encountered, risks, etc., must all be recorded based on these aspects.

The real process test case design begins when the approach is determined and approved by management.

Test design and Implementation

We identify the throughout this step:

  • Features to be tested
  • Derive the Test Conditions
  • Derive the coverage Items
  • Derive the Test Cases

Creating a test environment

In order to guarantee that the testing environment constantly resembles the production environment, we must set up and maintain the test computers during this phase.

Test Execution

Test cases are really run in this stage.

Bug report captured

If upon execution, the expected and actual results differ, the test case must be marked as failing, and a bug must be reported.

Why is necessary to perform dynamic software testing?

The benefits of dynamic testing make it simple to understand why it should be used during the software testing life cycle when we take a look at its capabilities (STLC).

With the use of this testing, the team can verify a number of important software features that, if left unchecked, may affect the product’s functionality, performance, and dependability.

The objectives of dynamic testing are:

  • It is a useful tool for determining how different environmental pressures, including those caused by hardware, networks, and other factors, affect software products.
  • The team’s ability to identify mistakes and flaws in the program is a key benefit of using dynamic testing.
  • The team runs the code throughout this procedure to evaluate how well the software product performs in a real-world setting.
  • It is used to evaluate the software’s functionality.
  • To guarantee that the software product complies with both the client’s and the end user’s requirements and goals.
  • Helps the team compare and verify the result with the desired outcome.
  • Most significantly, it aids the team in verifying the software’s overall performance.

Benefits of dynamic software testing

  • The undetected faults that are deemed too challenging or complex to be covered by static analysis can be revealed by dynamic testing.
  • In dynamic testing, we run the program from beginning to end to ensure that it is error-free, which improves the quality of a project or product.
  • For the purpose of identifying any security threats, dynamic testing becomes a crucial tool.

Drawbacks of dynamic software testing

  • Because it runs the program, code, or application that demands a significant number of resources, dynamic testing takes a lot of time.
  • Because dynamic testing does not begin early in the software lifecycle, any errors that are resolved at a later point may result in an increase in cost.

In a word, the sort of testing approach that is used in all businesses nowadays is dynamic testing. When implemented appropriately in businesses, it has effectively demonstrated outcomes of greater quality and is used as a tool that the QA can rely on. In software testing, this strategy is quite helpful.
