Introduction

Software testing is an essential part of software development and maintenance. It ensures that the software meets the specified requirements, performs as expected, and is free of errors, defects, and vulnerabilities. Software testing can be broadly classified into two categories: static testing and dynamic testing.

Static testing is a software testing technique that involves examining and evaluating the software code or documentation without executing it. It is used to check the syntax, style, design, and quality of the software code or documentation. Some examples of static testing are code reviews, inspections, walkthroughs, and static analysis tools.

Dynamic testing is a software testing technique that involves executing and evaluating the software code or system during runtime. It is used to test the dynamic behavior of the software code with different inputs and outputs, and to find any errors or defects in the software runtime environment. Some examples of dynamic testing are unit testing, integration testing, system testing, and acceptance testing.

In this blog post, we will introduce the types, techniques, and examples of dynamic testing. We will also explain how dynamic testing can help you improve the quality and security of your software systems.

Types of Dynamic Testing

Dynamic testing can be classified into two types: white box testing and black box testing.

White box testing

• White box testing is a dynamic testing technique that tests the internal structure or design of the software code. It requires the tester to have knowledge of the software code, logic, and algorithms. White box testing is also known as structural testing, clear box testing, or glass box testing.
• Some examples of white box testing are statement coverage, branch coverage, path coverage, and mutation testing. Some tools and frameworks for white box testing are JUnit, NUnit, PyUnit, Code Coverage, and CodeSonar.

Black box testing

• Black box testing is a dynamic testing technique that tests the functionality or behavior of the software code or system without knowing the internal details. It requires the tester to have knowledge of the software requirements, specifications, and expected outputs. Black box testing is also known as functional testing, behavioral testing, or opaque testing.
• Some examples of black box testing are equivalence partitioning, boundary value analysis, decision table testing, and state transition testing. Some tools and frameworks for black box testing are Selenium, Appium, Cucumber, TestComplete, and Postman.

Another type of dynamic testing that is gaining popularity and importance is dynamic application security testing (DAST). DAST is a dynamic testing technique that tests the security of the software code or system by simulating real-world attacks and vulnerabilities.

It requires the tester to have knowledge of the software architecture, network, and protocols. DAST is also known as penetration testing, ethical hacking, or vulnerability scanning. Some examples of DAST are SQL injection, cross-site scripting, buffer overflow, and denial-of-service attacks. Some tools and frameworks for DAST are Nmap, Metasploit, Burp Suite, ZAP, and OWASP.

Techniques of Dynamic Testing

There are many techniques of dynamic testing that can be used to test different aspects and features of the software code or system. Some of the common techniques are:

Functional testing: This technique tests the functionality or behavior of the software code or system according to the software requirements, specifications, and expected outputs. It verifies that the software code or system does what it is supposed to do and meets the user’s needs and expectations. Some examples of functional testing are unit testing, integration testing, system testing, and acceptance testing.

Regression testing: This technique tests the software code or system after any changes or modifications are made to it. It ensures that the changes do not affect the existing functionality or behavior of the software code or system and that no new errors or defects are introduced. Some examples of regression testing are retesting, selective testing, and smoke testing.

Performance testing: This technique tests the performance or efficiency of the software code or system under different conditions and scenarios. It measures the response time, throughput, resource utilization, scalability, reliability, and availability of the software code or system. Some examples of performance testing are load testing, stress testing, endurance testing, and spike testing.

Usability testing: This technique tests the usability or user-friendliness of the software code or system. It evaluates the ease of use, learnability, satisfaction, and accessibility of the software code or system from the user’s perspective. Some examples of usability testing are user interface testing, user feedback testing, and accessibility testing.

To choose the appropriate technique for dynamic testing, the tester should consider the following factors:

• Type and scope of the software code or system
• Purpose and objective of the testing
• Software development life cycle model and methodology
• Software testing strategy and plan
• Software testing tools and frameworks
• Software testing budget and schedule
• Software testing risks and challenges

Some of the best practices and challenges for dynamic testing are:

• Plan and design the test cases and scenarios carefully and comprehensively
• Use appropriate tools and frameworks to automate and simplify the testing process
• Execute and monitor the testing activities and results regularly and systematically
• Analyze and report the testing outcomes and findings accurately and objectively
• Communicate and collaborate with the software development team and stakeholders effectively and efficiently
• Update and maintain the testing artifacts and documents consistently and clearly
• Handle and resolve the testing issues and problems promptly and professionally
