Software Testing Methodologies Learn The Methods & Tools

As the world moves onto the online space, it opens up new avenues for cyber attacks. Thus, it is important that we ensure that our systems and applications have enough security to protect against these. And the best way is to test our system under simulated attacks and exploit the weaknesses by authorized personnel. Penetration testing helps in answering vital questions in regard to security standards and vulnerabilities. The developers perform unit testing by running the piece of code before passing it on to the testing team. On a broad level, Test Methodologies involve all the different types of functional and non-functional testing to validate the application.

If customer wishes or requirements are not met, you will have an opportunity to redo a specific part of the product. Each stage of this test method can be considered complete once a piece of code is written and tested. This model allows testing teams to quickly find errors and, more importantly, their causes. They are planning, risk analysis, engineering, and final evaluation. This approach allows teams to make changes to the product at an early stage and save time and resources in the future. As soon as a particular stage of development finishes, the team immediately starts testing a ready-made part of the product.

Software Testing Methodologies To Consider

The customer feedback thus obtained would be an input to the next / subsequent Iterations. Quality Testing ensures that the application does not result in any failures and defects are identified as early as possible.

Once the potential vulnerabilities are discovered, testers will leverage these to further enter the system. This closely resembles how a cybercriminal would exploit these security gaps and helps provide a better understanding. All the steps, tools used, location, and methods of entry for a particular issue are properly documented to capture the entire process for further review. As a step in the penetration testing methodology, these security issues are ranked based on their ease of exploitation and the damage they can cause. Quality testing methodologies result in a higher quality product, greater reliability on the product, and higher client and customer satisfaction. Veracode developers use the Agile methodology and find it the most effective method for both code development and testing, in particular security testing. Since testing occurs during the development phase in Agile, coding issues are found earlier when they are easier to fix.

Advantages of the Agile model

They break projects down into small segments of user functionality called user stories, prioritize them, and then continuously deliver them in two-week cycles called sprints. The testing methodology is also incremental — each small release is thoroughly tested to ensure quality.

• So it’s no surprise that teams are always on the lookout for the best possible testing approaches that will improve their QA strategy and influence the quality of their product.
• The main distinguishing feature of this approach is that the development process happens in parallel with the testing process.
• The Rational Unified Process is an iterative software development process framework created by the Rational Software Corporation, a division of IBM.
• Whether you work in agile development, Scrum and XP, Kanban and Lean, Waterfall, hybrid, or Scaled AgileInflectra can help.
• Some organizations take a test-first approach to software development, with testing methodologies such as TDD and BDD being the first step of code production.

To get around the issues related to manual testing, organizations generally use software to automate their testing processes to validate code. In addition, the people doing the work may be testing specialists (e.g. performance, security) but will be fully embedded in the agile teams. The agile methodology makes your SDLC fluid, and your team more able to adapt. The involvement of QA from the word ‘go’ means that your product will be well-tested, and better quality as a result. In the next articles, we’ll look at other types of software testing.

Once we have this information, we can go on to build the audit universe. Software companies don’t need to pick a singular software testing methodology — they can be combined and used at various stages during software development. Functional testing helps teams check their products against business objectives and specifications. It does not deal with the technical side of the product, such as performance, security, etc.

Imagine that you developed a SaaS application to allow storing photos with a feature that permits connecting the cloud to TV sets. In this case, functional testing would help you make sure that the app allows the user to store photos and watch them on TV. You would also be able to understand in more detail whether the app meets the customer’s requirements and show the client’s team the test results. There are a lot of articles about testing on the Internet, but most of them describe methodologies and types of software testing without solid classification. There are tons of methodologies available for software development and its corresponding testing. Each testing technique and methodology is designed for a specific purpose and has its relative merits and demerits. A penetration testing methodology is a combination of processes and guidelines according to which a pentest is conducted.

But with an increase in complexity, the requirements undergo numerous changes and continuously evolve. Though the iterative model addresses this issue, it’s still based on the waterfall model. At Astra, we offer manual & automated penetration testing with our one-of-a-kind Pentest Suite.

Also, some problems can arise if a team has to test the localization of products for exotic regions. For example, is the application compatible with Microsoft products? You will be able to answer these questions through compatibility tests. This is a test of how the product behaves when there is sudden and unexpected user load. Spike testing will show you whether the product withstands the demand or crashes, so you can make necessary adjustments. This type of testing can help you see how long an application can run at average load, and whether it is stable over an extended period. Can the app work in a normal mode only for a few hours before lagging or crashing?

Waterfall Method

Since software errors can cost businesses money and customer trust, testing is an integral part of the development process and used in some flavor by every software company. Functional testing is done using the functional specifications provided by the client or by using the design specifications like use cases provided by the design team. Therefore the test cases they will need to execute, will need to be more prescriptive and outline the discrete steps / tasks to be carried out. Automated functional tests and manual testing depending on how easy it is to create automated tests for specific integrated components. As soon as one iteration is completed, the entirety of the software is subjected to testing .

To have an effective penetration test, it is necessary to conduct proper reconnaissance and gather intel on the systems. By using various tools, automated and manual, testers will check the system to find any potential vulnerability or entry points. Tools such as Recon-Ng, Nmap, Spiderfoot, Metasploit, Wireshark, are commonly used for this. Chartering involves forming a development team, carrying out a preliminary feasibility analysis, arriving at an initial plan and the development methodology. EXtreme Programming is customer-centric and focuses on constantly changing requirements.

Software Testing Methodologies

These methodologies are particularly relevant for teams that use an agile, or iterative, approach to software development. Teams don’t have to pick one testing solution and stop there — several approaches can be used by the same team at different stages of development. The following sections take a closer look at TDD and BDD and where they fit into the development cycle to give some more context on testing methodologies in practice. Learn about software testing methodologies and some specific strategies that use a test-first approach to software development. To create an audit universe, testers might use a top-down approach to state the business objectives, important applications and processes, and infrastructure. This helps in creating this universe which serves as an inventory for the testers, and forms the foundation of the penetration testing methodology.

Transparent reporting is very difficult to achieve, but this step determines the effectiveness of the testing approach used in the project. Selection of a particular methodology depends on many factors such as the nature of a project, client requirement, project schedule, etc. The main advantage of iterative development is the test feedback is immediately available at the end of each cycle. You also receive detailed steps (including video PoCs, selenium scripts, etc.) on how to reproduce the vulnerability. Ensuring that the right test types are run at the right time and as part of the right test level.

Development

In the waterfall model, you can begin with the next phase only once the previous phase is completed. Hence, this model cannot accommodate unplanned events and uncertainty. Our security researchers go the extra mile and assist your developers with remediation. Once security vulnerabilities are unearthed, testers will devise strategies and solutions to fix them. In their final reports, solution steps will be compiled for all the issues and additional suggestions to keep the system secure.
