<h2 id="h-what-is-model-based-testing">What is Model Based Testing?</h2>



Model-based testing, often abbreviated as MBT, is a systematic approach to software testing where abstract models are used as a basis for designing and generating test cases. These models represent the expected behaviour of the system under test, including various states, inputs, and expected outcomes. Test cases are automatically derived from these models, reducing the need for manual test case design. This method aims to increase testing efficiency, improve <a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener">test coverage</a>, and facilitate early defect detection by aligning the testing process with the models created, making it an essential tool in modern software quality assurance.



<h2 id="h-model-based-testing-example">Model Based Testing Example</h2>



For instance, if you have a transition in the model from &#8220;Login&#8221; to &#8220;Transfer Funds,&#8221; the testing tool can automatically generate test cases. These cases ensure that the application allows users to log in successfully, select accounts for transferring funds, and verifies that the transaction is executed accurately.



As the banking application evolves with new features or updates, you can adapt the model, and the testing tool will automatically generate updated test cases. This approach streamlines testing, enhances coverage, and accelerates the detection of defects, making Model-Based Testing an asset in ensuring software quality.

Model-Based Testing (MBT) is a systematic approach to software testing that uses abstract models to design and generate test cases. Here are the seven key steps in how MBT works, with a more detailed explanation for each step, consisting of three points:



<h3 id="model-creation">Model Creation:</h3>



<ul><li>Create an abstract model that represents the expected behaviour of the system under test. This model defines states, transitions, and inputs. </li><li>The model can use various techniques, such as finite state machines, statecharts, or decision tables. </li><li>The modelling process often involves collaboration between testers, developers, and domain experts to ensure accuracy.</li></ul>



<h3 id="model-validation">Model Validation:</h3>



<ul><li>The created model is subject to validation to ensure it accurately reflects the intended system behaviour. </li><li>Validation involves reviews, inspections, and simulations to ensure the model&#8217;s correctness. </li><li>Stakeholders, including domain experts and developers, provide feedback to validate the model.</li></ul>



<h3 id="test-case-generation">Test Case Generation:</h3>



<ul><li>Once the model is validated, <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test cases </a>are automatically generated from the model. </li><li>These test cases are derived from the model&#8217;s states, transitions, and inputs, ensuring that various system behaviours are covered. </li><li>Automated test case generation saves time and effort compared to manual test case design.</li></ul>



<h3 id="test-execution">Test Execution:</h3>



<ul><li>The generated test cases are executed against the actual system under test. </li><li>This involves interacting with the software, providing inputs, and observing how the system responds. </li><li>The behaviour of the system is closely monitored during test execution.</li></ul>



<h3 id="result-comparison">Result Comparison:</h3>



<ul><li>During test execution, the observed behaviour of the system is compared to the expected behaviour defined in the model. </li><li>Testers compare the actual outcomes with the predicted outcomes, and any discrepancies are identified. </li><li>This step helps in identifying failures or issues in the software.</li></ul>



<h3 id="defect-reporting">Defect Reporting:</h3>



<ul><li>When discrepancies or defects are discovered during testing, they are reported to the development team. </li><li>Early defect detection is a significant advantage of MBT, allowing for timely resolution of issues. </li><li>Detailed defect reports typically include information on the issue, the test case that triggered it, and the model element involved.</li></ul>



<h3 id="model-maintenance-and-iteration">Model Maintenance and Iteration:</h3>



<ul><li>As the system evolves or changes are made, the abstract model is updated to reflect these modifications. </li><li>Test cases can be regenerated based on the updated model, ensuring that testing remains aligned with the current state of the application.</li></ul>



<ul><li>The iterative nature of MBT allows for continuous refinement and adaptation based on feedback and evolving requirements.</li></ul>

One striking example is the Equifax Data Breach of 2017. The security breach exposed the personal information of 147 million US consumers, triggering a crisis. Equifax found itself in the unenviable position of having to work diligently to rebuild customer trust and reputation. It leads to the following:


<ul>
<li>Increased Customer Acquisition Efforts: Equifax had to invest significantly in rebuilding trust. This involved extensive marketing and communication efforts to address customer concerns and promote improved security measures.</li>
<li>Impact on Attracting New Customers: The incident cast a long shadow over Equifax&#8217;s ability to attract new customers. Heightened regulatory scrutiny, which indirectly impacted customer acquisition costs, added to the financial burden.</li>
</ul>

<div class="wp-block-image"> </div>


Throughout all these diverse examples, one thing is absolutely clear i.e., the cost of a software defect is a multifaceted and interconnected web of consequences. From the immediate financial hits to the long-term damage to reputation, from the toll on an organization’s morale to the need for extensive legal and public relations efforts, defects can wreak havoc in unpredictable ways.


The complexities of these costs serve as an important reminder of the critical importance of rigorous testing and quality processes in the software development process. Identifying and addressing defects early can save organizations from the maze of trouble and consequences.


Here are a few lessons to take from the case studies &amp; exploration of various costs associated with the defects:


<ol>
<li>Invest in Testing: Rigorous testing and quality practices are not optional—they are essential. The cost of fixing defects after they&#8217;ve reached production can be exponentially higher. Checkout our open source tool to accelerate your testing effort.</li>
<li>Consider the Human Element: Software defects don&#8217;t just impact systems; they impact people. Customer’s morale, trust, and satisfaction are intangible yet invaluable assets. Do join our free discord community to stay up to date with fellow professionals and be on top of your quality and testing game.</li>
<li>Trust is Priceless: Once trust is shattered, the cost of rebuilding it can be exorbitant. Trust is a currency that can&#8217;t be quantified but holds immeasurable value.</li>
<li>Prepare for the Unpredictable: Defects can manifest in unexpected ways and places. A proactive stance towards testing and quality is the best defense.</li>
</ol>




<blockquote class="wp-block-quote has-text-align-center">
“Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution.”
</blockquote>


John Ruskin


Like a hidden iceberg lurking beneath the surface of the sea, with the potential to sink even the mightiest of ships, defects exist in the software world.


Understanding and mitigating these costs should be at the forefront of every organization&#8217;s software strategy. As we navigate the ever-evolving digital landscape, let&#8217;s do so with a keen awareness of the hidden consequences that lie beneath the surface.

<h2 id="h-what-is-fault-based-testing">What is Fault-Based Testing?</h2>



Fault-based testing is a software testing method that identifies faults, errors, and defects within a software system. It introduces various types of faults like syntax and semantic errors to assess the system&#8217;s ability to handle unexpected inputs effectively. By employing techniques like mutation testing and fuzz testing, it aims to uncover vulnerabilities and weaknesses that might lead to software failures.



Fault-based testing is crucial for enhancing software quality, improving robustness, and proactively addressing potential issues before they impact end-users. It is often integrated with other testing approaches to provide a comprehensive assessment of a software application&#8217;s reliability and resilience.



<h2 id="h-a-theory-of-fault-based-testing">A Theory of Fault-Based Testing</h2>



This theory is built on the principle that software is prone to faults and errors, and the systematic identification and evaluation of these faults can lead to the discovery of potential vulnerabilities and weaknesses. The theory posits that by intentionally introducing various types of faults, such as coding errors, logical mistakes, or boundary condition violations, testers can assess how a software system responds to these issues and determine the effectiveness of error-handling mechanisms. This approach helps improve software quality and reliability by proactively addressing defects before they can manifest in real-world scenarios.



These techniques are applied in a controlled manner to explore various fault scenarios, ensuring that the software is robust and resilient in the face of unexpected inputs and errors. Overall, a theory of fault-based testing provides a systematic framework for enhancing software quality and uncovering hidden issues, contributing to more reliable and resilient software systems.



<h2 id="h-fault-based-testing-techniques">Fault-Based Testing Techniques</h2>



Fault-based testing techniques are critical methods used to introduce and evaluate faults, errors, and defects in software to ensure its robustness and reliability. Several key fault-based testing techniques are commonly employed:



<h3 id="h-mutation-testing">Mutation Testing</h3>



Mutation testing involves the deliberate introduction of artificial faults (mutations) into the source code. These mutations represent common programming mistakes, such as changing an operator or variable. Test cases are then executed against the mutated code to assess whether they can detect and reveal the introduced faults. The effectiveness of the test suite is measured by its mutation score, indicating how many mutations were successfully detected.



<h3 id="h-fuzz-testing"><a href="https://testsigma.com/blog/fuzz-testing/" target="_blank" rel="noreferrer noopener">Fuzz Testing</a></h3>



Fuzz testing, or fuzzing, focuses on feeding the software with a variety of malformed, random, or unexpected inputs. This technique is particularly useful for uncovering vulnerabilities and security flaws in a system. Fuzzers automatically generate and send inputs to the software, monitoring its behavior for crashes or unexpected responses. By doing so, fuzz testing helps identify issues in input validation, boundary checking, and exception handling.



<h3 id="h-boundary-value-analysis">Boundary Value Analysis</h3>



Boundary value analysis concentrates on testing at the extreme boundaries of input domains. Test cases are designed to assess how the software handles values near the edges of the valid input range. For example, if a software system accepts integers from 1 to 100, boundary value analysis would test values like 0, 1, 100, and 101 to uncover potential errors or misbehavior caused by boundary conditions. This technique is effective at exposing off-by-one errors and similar issues.



<h3 id="h-error-guessing"><a href="https://testsigma.com/blog/error-guessing/" target="_blank" rel="noreferrer noopener">Error Guessing</a></h3>



Error guessing is an informal testing technique that relies on testers&#8217; experience and intuition to identify potential fault scenarios. Testers use their knowledge of common programming mistakes, system vulnerabilities, or areas where errors are likely to occur. They then create test cases based on these insights, attempting to provoke errors based on their educated guesses. While less systematic than other fault-based testing techniques, error guessing can be a valuable addition to the testing process, leveraging the tester&#8217;s domain expertise.



These fault-based testing techniques play a crucial role in the software testing process, collectively contributing to the identification and resolution of defects and vulnerabilities that may compromise the reliability and performance of a software system. By intentionally introducing and assessing faults, software testers can enhance software quality and reduce the risk of unexpected failures in real-world scenarios.



<h2 id="h-fault-based-test-suite-prioritization-for-specification-based-testing">Fault-Based Test Suite Prioritization for <a href="https://testsigma.com/blog/specification-based-testing/" target="_blank" rel="noreferrer noopener">Specification-Based Testing</a></h2>



Fault-based test suite prioritization for specification-based testing is a strategy to determine the order in which test cases are executed based on their likelihood of uncovering defects in the software. The basic idea of this strategy is to identify and fix critical issues early in the testing process.&nbsp;



For example, imagine a software application for online shopping. A prioritization method could start by running test cases that involve fundamental functionalities like user login and product search. These are considered high-priority because issues in these areas could affect the entire application. As testing proceeds, lower-priority <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test cases</a> for less critical features, such as user preferences or advanced filtering options, can be executed. By following this prioritization, if a major fault is detected early during testing, it can be addressed promptly, reducing the risk of high-impact issues in the final product. This approach optimizes testing efforts by focusing on areas that have the potential to cause significant problems.



<h2 id="h-assumptions-in-fault-based-testing">Assumptions in Fault-Based Testing</h2>



Fault-based testing relies on several key assumptions to effectively identify and address faults and defects in software. One such assumption is that the intentional introduction of faults will expose weaknesses in the software. Here are some assumptions of fault-based testing along with an example:



Introducing Known Faults: One of the core assumptions in fault-based testing is that by deliberately injecting known faults into the software, you can assess how well it handles these issues. This assumes that the presence of these faults will lead to observable defects.



For instance, consider a web application, you intentionally introduce a fault by modifying the login process code to reject valid usernames and passwords. When you test the system with this fault, you expect it to fail to authenticate users and generate an error message.



Defects Correspond to Faults: Fault-based testing assumes that the defects observed in the software are directly related to the introduced faults. This means that when you identify a problem, it can be traced back to a specific fault that was introduced during testing.



While performing mutation testing, you change a multiplication operator (*) to a division operator (/) in a critical calculation function. If the test cases that rely on this function produce incorrect results, you can trace the defect back to the introduced fault, which is the operator change.



Test Cases Detect Introduced Faults: Fault-based testing assumes that the test cases are capable of detecting the introduced faults. Test cases are designed to expose the errors that are introduced into the software, ensuring they can effectively reveal these issues.



Let&#8217;s say you introduce a fault in a sorting algorithm that causes it to produce incorrect results when presented with a sorted input. Test cases are then executed to determine if the algorithm can identify and correct this error, showing that the test cases are capable of detecting the introduced fault.



Detected Faults Represent All Faults: This assumption implies that the faults discovered during testing are representative of the entire spectrum of potential faults in the software. It assumes that if the introduced faults are detected, other similar faults in the code will also be uncovered.



During mutation testing, you introduce a set of specific faults into the code. If these introduced faults are detected and resolved, it&#8217;s assumed that similar types of faults within the codebase will also be addressed.



These assumptions underpin the effectiveness of fault-based testing in identifying and addressing issues in software. However, it&#8217;s important to recognize that fault-based testing may not uncover all types of faults or defects, as not all issues are related to the specific introduced faults. Nevertheless, this methodology remains a valuable tool in improving software quality and robustness.



<h2 id="h-what-are-the-benefits-of-fault-based-testing">What are the Benefits of Fault-Based Testing?</h2>



Fault-based testing offers several benefits for software development and quality assurance processes. Here are some of the key advantages:



Defect Detection: is effective in identifying defects and weaknesses within a software system. We do this by intentionally introducing faults and errors and this methodology can reveal issues that might remain hidden during regular testing.



Improved Software Quality: Identifying and addressing defects early in the development process leads to improved software quality. By fixing issues proactively, the software becomes more reliable, robust, and resilient.



Security Vulnerability Identification: Fault-based testing, particularly techniques like fuzz testing, can uncover security vulnerabilities, such as buffer overflows and injection attacks. By exposing these vulnerabilities, the software can be hardened against potential cyber threats.



Cost Savings: Detecting and fixing defects early in the software development process is more cost-effective than addressing issues after the software is deployed. Fault-based testing can save organizations substantial time and resources in the long run.



<a href="https://testsigma.com/guides/quality-assurance/" target="_blank" rel="noreferrer noopener">Quality Assurance</a>: Integrating fault-based testing with other testing methodologies ensures comprehensive quality assurance. It complements techniques like unit testing, <a href="https://en.wikipedia.org/wiki/Integration_testing" target="_blank" rel="noreferrer noopener">integration testing</a>, and system testing to provide a well-rounded assessment of software reliability.



Compliance and Regulation: In industries with stringent compliance and regulatory requirements, such as healthcare and finance, fault-based testing helps ensure that software meets these standards by identifying and addressing potential issues.



<h2 id="h-conclusion">Conclusion</h2>



In conclusion, fault-based testing stands as an indispensable pillar of <a href="https://testsigma.com/guides/quality-assurance/" target="_blank" rel="noreferrer noopener">software quality assurance</a>, enabling developers and testers to unearth hidden defects, vulnerabilities, and weaknesses in software systems. By introducing known faults, this systematic methodology offers a unique perspective, shedding light on how a software application responds to errors and erroneous inputs.

Static analysis or static code analysis is used by developers and software testers to detect coding defects. Static analysis in software testing is not new, at least not for software testers with coding knowledge or experience. Static analysis involves reviewing the code similarly to performing a code or peer review. 


Static analysis helps software testers fully understand how the code functions and its structure. Software testers can execute code in isolation and review for errors. Static analysis reviews by software testers also help ensure code meets organizational and industry standards. 


This guide describes the types of static code analysis in software testing, how it’s performed, and its benefits for software testing coverage.

<h2 id="h-how-is-static-code-analysis-done">How is static code analysis done?</h2>


Static analysis like other <a href="https://testsigma.com/guides/software-testing/" target="_blank" rel="noreferrer noopener">software testing</a> can be done either manually or by using automation. Static analysis in software testing typically occurs early in the development process. Static code analysis can fulfill testing responsibilities when it’s not possible to test a feature fully in the application. 


If static analysis is performed manually it is done either by using pair testing with a developer or by stepping through the code line by line in a formal setting similar to a code review. In either case, the software tester must follow along and ask any questions necessary to understand the functionality. It’s important to consider the individual code under review as well as its impact on the application functionality as a whole. The code is executed manually to verify no errors exist. 


When static analysis is performed using automated tools, testers typically use a static code analyzer tool. Static code analyzer tools check the code against defined rules and any related standards. Most tools allow users to determine what standards are checked and to set custom guidelines as well. The code is executed by the tool, and any issues are flagged for review.

<h2 id="h-summary">Summary</h2>


Static code analysis in software testing provides testing coverage at the early stages of development as well as throughout the development cycle. Software testers benefit from learning the internal code structure and function which can help create functional and <a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">regression tests</a> that execute defined code components in full. 


For fuller and deeper test cover, consider including testing using static code analysis manually or by using an automated tool.

<div class="schema-faq wp-block-yoast-faq-block"><div class="schema-faq-section" id="faq-question-1753349099974">What is an Example of Static Analysis? In the example below, the OWASP Lapse+ tool provides a typical interface for viewing and analyzing code components. </div> <div class="schema-faq-section" id="faq-question-1753349139472">Why is it called static code analysis? Because the testing is performed outside the application UI. Since the code is not being executed dynamically as required, it is static. Testers are reviewing and stepping through code components that are not active. </div> </div>
