How many types of software test methodologies are there?

Let’s explore the various types of software testing methodologies:

Waterfall Model

The waterfall software testing methodology uses sequential steps to plan, execute, and maintain software. The next step can only be started once the previous one is completed. This methodology has five predefined stages, including:

• Requirements
• Design
• Implementation
• Verification
• Maintenance

This software testing methodology is perfect for small and less complicated projects. Since it has fewer players and procedures, this method tends to speed up test procedures.

Advantages of the Waterfall Model:

• Its step-by-step strategy is very easy to follow.
• This software testing methodology is inexpensive and often results in faster development cycles.

Disadvantages of the Waterfall Model

• Inflexible because you can’t skip or record its steps.
• Even small modifications to this methodology can lead to large expenses.

Iterative Model

The iterative software testing methodology focuses on continuous improvement and feedback. Unlike Waterfall, this methodology focuses on breaking down a project into smaller components, where each of them is iterated and tested before merging into a final product. 

This testing approach is perfect for larger software products that need to be finished rapidly. Further, it’s ideal for flexible software where the requirements are loosely defined, and scalability is an important factor.

Advantages of the Iterative Model

• Error and bugs are resolved early because of the iteration cycle.
• More flexibility in design
• Results and feedback of each iteration are immediately available for analysis.

Disadvantages of the Iterative Model

• Overlapping iteration cycles is not possible
• Since planning and documentation are low priorities in this software testing methodology, it could result in unexpected circumstances that may delay your project.

Agile Model

The agile model, unlike the waterfall method, is well suited for big development projects. In an agile software testing methodology, tests are executed at the end of each increment or iteration. Additionally, the complete software is also tested at the end of the project. 

The agile model delivers incremental deliverables throughout the processes rather than delivering complete work like the iterative model. It also allows the stages to overlap and includes frequent communication with stakeholders to continually refine requirements. 

With this software testing methodology, each cycle is tested thoroughly to create a deliverable to be presented to the stakeholders and adapted to the feedback.

Advantages of the Agile Model

• It reduced the risks of numerous changes and expensive fees.
• Continual communication means everyone is informed of the progress

Disadvantages of the Agile Model

• This may result in longer delivery time due to back and forth between the stakeholders and the developers
• It can be tedious to test each stage so often thoroughly.

Spiral Model

The spiral model is a quality assurance technique incorporating both waterfall and iterative approaches. In addition, it is parallel to the incremental methodology, with more concentration on threat analysis. Various stages of the spiral model comprise the planning stages, risk analysis, assessments, etc.

Advantages of the Spiral Model

• This software testing methodology uses the time box approach at every incremental phase, which reduces the overall threats significantly.
• It has robust documentation support and can function well with bigger and more critical projects.

Disadvantages of Spiral Model

• It is not suitable for small projects and can be expensive.
• This method is quite difficult to use with legacy systems.

Extreme Programming Model

This software testing methodology breaks the job into smaller sections, and after every section is finished, the next section is operated on. This method is used where the requirements of the users are constantly evolving. 

There are two teams, one functions with the code, and the other team instantly reviews it. Every phase of this testing technique can be considered finished when excellently written and tested.

Advantages of Extreme Programming Model

• QAs can create superior-quality code because each line is scrutinized.
• Perfect for customers with vague software designs.

Disadvantages of the Extreme Programming Model

• Considerable time loss between the development team and customers for brainstorming
• This software testing methodology prioritizes code rather than design.
• Constant Changes make documentation difficult.

DevOps Approach and Continuous Testing

Using this testing methodology in software testing, developers don’t have to wait to perform testing until software completion. Instead, they test the software continuously during the building processes to ensure quality and compliance with requirements. Continuous testing uses automated test methods to provide immediate feedback during the build process on any risks that might exist.

Advantages of the DevOps Approach

• DevOps approach prompts continuous integration and continuous delivery, enabling rapid deployments and bug fixes.
• This software testing methodology fosters collaboration between testing and operations teams.

Disadvantages of the DevOps Approach

• DevOps relies heavily on automation and integration of various tools. For large projects, this can cause complexities and may require additional expertise.

Importance of choosing the right software testing methodology

Selecting the most suitable testing methodology is crucial if you want your software to succeed. Here is how it can impact your product:

• Perfect project fit: Different methodologies cater to different project needs. Therefore, you should choose a software testing method based on your specific needs.
• Efficiency and effectiveness: Each software testing methodology offers its own unique strengths. For example, agile promotes early and continuous testing for faster bug detection and improved adaptability. On the other hand, waterfall prioritized clear documentation and stricter control. Therefore, it's very important that you find the right balance between effectiveness and efficiency.
• Team dynamics: It's important that the software testing methodology complements your team's capabilities, as understanding your team’s strengths can lead to successful adoptions.
• Proactive risk management: Testing methodologies are not just about finding bugs; the right methods will help you mitigate quality, schedule, and budget risks throughout the project’s lifecycle.
• Meeting expectation: If delivery is your priority, then agile is the right choice for you; however, if the stakeholders focus more on documentation, a traditional method like waterfall would be better suited. Therefore, before you implement a software testing methodology, it is important to align your approach with the expectations.
