My Greeting to Testers and Automation people! My name is Piyush Srivastava, and I’m working as Tester in functional & Automation for around 6 years on various projects as a Senior Consultant and SME. Now I’m working in *Luxoft * where I got great chance to upskill myself in better way. I wanted to share some Static and Dynamic Testing thoughts with you.
If you are a tester or software developer, you probably know how important it is to deliver high-quality products in a fast and efficient way to end users. That’s why continuous testing is becoming a key practice in the software development lifecycle. Continuous testing is the process of testing software continuously throughout its development and deployment stages, ensuring that it meets the requirements and expectations of the users and stakeholders.
In this article, I will talk about static and dynamic testing; two complementary testing techniques that can help you improve the quality of tested software. Static testing is checking the code, design, and documentation without executing the software. Dynamic testing is testing the software by running it and observing its behavior.
Both techniques have advantages and disadvantages, but when used together, they can provide a more comprehensive and effective testing strategy.
Dynamic testing vs static testing
Dynamic testing and static testing are two types of software testing that have different purposes and methods. Dynamic testing is the process of testing software by executing it with various inputs and scenarios and checking its behavior and outputs. Static testing is the process of testing software by analyzing its code, design, documentation, and configuration, without executing it.
Both dynamic and static testing are essential for continuous testing, as they can help you identify and fix defects at different stages of the software development lifecycle. Dynamic testing can help you verify the functionality, usability, reliability, security, and performance of your software, while static testing can help you improve the quality, maintainability, readability, and compliance of your code.
How Dynamic and Static Testing Support Continuous Testing
Continuous testing requires a high level of automation and integration of different tools and processes. Dynamic and static testing can support continuous testing by providing fast and accurate feedback on your software quality and performance, enabling you to make informed decisions and take corrective actions.
Dynamic testing can support continuous testing by:
Automating your test cases and test suites using tools like Selenium, TestNG, JUnit, etc.
Integrating your test automation with your continuous integration (CI) and continuous delivery (CD) pipelines using tools like Jenkins, Bamboo, Azure DevOps, etc.
Running your tests in parallel on different environments and devices using platforms like LambdaTest.
Generating test reports and dashboards using tools like Allure, TestRail, ReportPortal, etc.
Monitoring your software performance and availability using tools like AppDynamics, New Relic, Dynatrace, etc.
Static testing can support continuous testing by:
Analyzing your code quality and complexity using tools like SonarQube, Code Climate, Codacy, etc.
Detecting code smells, bugs, vulnerabilities, and technical debt using tools like PMD, FindBugs, Checkstyle, etc.
Enforcing coding standards and best practices using tools like ESLint, Prettier, StyleCop, etc.
Reviewing your code changes and providing feedback using tools like GitHub, GitLab, Bitbucket, etc.
Documenting your code and design using tools like Javadoc, Doxygen, Sphinx, etc.
*Continuous testing is a vital practice for enterprises that want to deliver high-quality software in a fast and efficient way. Dynamic and static testing are two types of software testing that play a crucial role in continuous testing for enterprises. By combining dynamic and static testing techniques and tools in your software development lifecycle, you can improve your software quality and performance significantly. *
*Complementary testing techniques are methods that can be used together to enhance the quality and coverage of software testing. They are not meant to replace each other, but rather to supplement and support each other. *
*Static Testing -What is and when do we use it? *
Static testing includes testing all software components or systems without actually running them. It is known as “static” because we run this type of testing without executing the code. Testers often use several techniques to conduct static testing. These include review, inspection, walkthrough, and static analysis.
One of the main benefits of static testing is the early identification of defects. When you can catch errors before the actual code runs, be sure it will save significant time and effort for developers. You will see that static testing is especially useful for testing large or complex code to avoid time-consuming debugging later on.
Static testing can also reduce the overall testing time required for a project. Since it does not involve executing the code, it can be much faster than dynamic testing. Static testing is beneficial for projects with tight deadlines or limited resources.
Besides saving time and effort, static testing can also improve the quality of the code. When you identify and address defects early in the development process, in the end, developers will have a product with fewer bugs. This is a clear path to increase customer satisfaction. And even cost savings by avoiding the need for rework or debugging once the software is in use.
Despite its benefits, there are also some limitations to static testing.
One of the main limitations is the scope of the analysis. Static testing can only identify defects you can see without executing the code. Some defects will only occur when the code is running and thus will not be detected through static testing.
Another potential issue with static testing is the risk of false positives. It means they can identify a defect that will not harm the actual running of the software. So, you will waste your time investigating and addressing these false positives.
In addition, using static testing tools, you can only analyze the code or design available at that time to you. When you don’t include certain parts of the code in the analysis, defects in those parts probably won’t be identified. All this can result in limited coverage and potentially missed defects.
Overall, static testing is an important part of the software development process. Use static testing in combination with other testing techniques like dynamic testing. Static testing will give you a comprehensive view of the software and help developers produce a high-quality product.
Dynamic Testing -What Is and When Do We Use It?
Dynamic testing is a testing method of evaluating the behavior of a software application or system by executing it and observing the results. This type of testing is also known as “run-time testing” because it involves running the code and interacting with it while running.
One of the main goals of dynamic testing is to identify defects or bugs in the code that may not be detectable through static testing methods, such as code review or static analysis. Dynamic testing is often used together with static testing and provides a more accurate evaluation of an application’s quality.
