All About Static and Dynamic Testing

Static and dynamic testing are testing types used in software quality assurance. Software testing is verification (Static Testing) and, at the same time, validation (Dynamic Testing). They have differences, of course. Let us learn more about them.

What is Static Testing?

Static testing method requires programmers to read their code to find any errors manually. It is a stage of White Box Testing. Static testing is a software testing technique by which we can check the defects in software without actually executing it.

Static Testing Types

  • Manual examinations or reviews: Manual examinations include analysis of code done manually. It is typically used to find and likewise, eliminate errors or ambiguities in documents such as requirements, design, test cases, etc.
  • Automated analysis using tools: Automated analysis is a static analysis which is done using instruments. Furthermore, the code written by developers is analyzed for structural defects that may lead to errors.

Benefits of Static Testing

  1. Fewer defect at a later stage of testing
  2. Reduced development timescales
  3. For improvement of development productivity
  4. Early defect detection and also correction
  5. Reduced testing cost and likewise of time

Defects Found by Static Testing

  • Security vulnerabilities
  • A variable with an undefined value
  • Programming standards violations
  • The inconsistent interface between modules and also components
  • Syntax violations
  • Unreachable code or Dead Code

The Static Testing Process

Step 1: Use Cases Requirements Validation

The more detailed and thorough the use cases are, the more accurate and likewise,comprehensive the test cases can be.

Step 2: Functional Requirements Validation

It ensures that the Functional Requirements identify all necessary elements. It also looks at the database functionality, interface listings, and hardware, software, and network requirements.

Step 3: Architecture Review

All business-level processes like server locations, network diagrams, protocol definitions, load balancing, database accessibility, test equipment, etc.

Step 4: Prototype or Screen Mockup Validation

This stage includes validation of requirements and use cases.

Step 5: Field Dictionary Validation

Every field in the UI is defined to create field-level validation test cases. 

Dynamic Testing

Dynamic Testing checks the dynamic behavior of the analyzed code. It requires working with the actual system.  Hence, by providing input and comparing the actual behavior of the application to the expected behavior.

In other words, working with the system with the intent of finding errors. The primary purpose of the dynamic test is to ensure the consistency of the software.

Types of Dynamic Testing

Black Box Testing

Black Box Testing is a method of testing in which the internal structure, code, and also, the design is unknown to the tester. The main aim of black box testing testing is to verify the functionality of the system under test. Therefore, there is no need for any programming knowledge.

White Box Testing

The main aim of White Box testing is to check on how the system is performing based on the code.

Dynamic Testing Techniques

  • Test Design and Implementation: The features to be tested are identified in this phase.
  • Setting Up the Test Environment: We have to ensure that the Testing Environment is always similar to the Production environment. Therefore, we have to install the build and manage the test machines.
  • Test Execution: This phase involves the actual execution of the test.
  • Bug report captured: The test is a failure, depending on the result of test execution.  Thus, if the expected and also the actual results are not the same. Therefore, it need to report a bug.

To Conclude

Both Static testing and Dynamic testing aims to improve the quality of software products. Static testing detects errors without the actual execution of the test. Dynamic testing, on the other hand, executes actual testing  for bug detection.
