Testing is a complex process, therefore, it requires a clear and suitable methodology for its performance.
There are many approaches and strategies that you can take advantage of to test the product to make sure that it meets the requirements and consumer expectations. Next, we will analyze the main testing methodologies and the procedure for setting them up depending on the specifics of the project.
Testing Methodology Definition and Overview
A software testing methodology is a collection of variable approaches and strategies for testing that guarantee thorough and high-quality software examination. Since there are many different methodologies, you should choose the one that suits you best based on the project requirements, scope, deadline, etc. Choosing the right and appropriate testing methodology is the key to effective verification of a program or application and its successful release and usage.
Here are some of the most common of them used for software testing.
Waterfall Model
It is one of the classic approaches to product analysis when program testing is carried out before its release. It got its name because each testing phase begins after the previous one is completed. Testing is not implemented throughout the development process, so testers and developers have almost no cooperation. It is not a flexible model, but it has its advantages.
Iterative Methodology
It is a flexible approach to product testing. Since software verification is integrated into the development process from the beginning, testers are able to detect and fix existing defects early. It is an adaptive strategy that constantly contributes to the testing process improvement.
Agile Model
This methodology consists of organizing the workflow in the form of sprints. They are short development cycles that are constantly checked by software testers. It guarantees close cooperation between developers and QA engineers and allows you to control and improve the process throughout the software development life cycle.
Extreme Testing
It is another flexible approach to software testing when testers and developers work side by side from the beginning. Testing is implemented at every stage of design and development, so this strategy is highly disciplined and effective.
Criteria for Determining the Optimal Methodology
Sometimes choosing the most suitable methodology for testing can be difficult. Here is a list of the main factors that you should take into account when determining the approach to product testing:
Scale and schedule of software development. Typically, the waterfall model is used for testing small programs, while the agile methodology is appropriate to implement when the project is large and needs to be developed and tested in parts.
Effectiveness of the strategy. If your software is complex, detecting bugs at the final stage can lead to release delays and extra costs.
Skills and habits of the team. In case your team has less experience working according to the waterfall model, its implementation may require a lot of time to adapt to the new approach.
The choice of methodology may depend on other circumstances. Each project is unique, therefore it requires a special approach.
Methodology Setup Process
Implementing a methodology is often a long-term process that requires effort. To conduct product testing effectively and quickly, you should act as follows:
- Define the goals and objectives of testing.
- Select the most suitable methodology.
- Choose the types of testing you will conduct.
- Prepare the environment and tools you need.
- Create and execute tests.
- Analyze the results.
- Repeat testing after making adjustments.
- Perform regression testing after each software update.
The testing setup procedure in your company may slightly differ. It depends on the methodology you choose.
The Main Benefits of a Properly Chosen Methodology
The methodology you select will definitely affect the testing results. If you choose the wrong approach or strategy, you risk wasting time, money, and reputation. By determining the optimal methodology, you will receive:
- Improved software quality. The product will be tested thoroughly, and therefore its users will receive a convenient and reliable program.
- Timely error elimination. You will be able to detect bugs at the initial stages and eliminate them with less stress and effort.
- Reduced costs. If you plan the process correctly, you are unlikely to face extra costs.
- Accelerated release. Effective testing will speed up the software development process so you will be able to release it faster.
- Increased software success. A program or application that works smoothly has a better chance of success after release.
