Testing is one of the most critical stages of software development. It allows you to identify all possible errors, fix them, and provide your customers with a top-quality product. For this to be as effective as possible, you need to choose the right way of software testing. The choice depends on many factors that can be divided into 2 categories: internal and external. Let’s look at the most important of them in more detail.
Why is testing necessary?
Testing is a reliable way to find possible bugs in software or prevent new ones. No matter how experienced your programmers are, they can make mistakes. This can be compared to the work of a journalist; no matter how good he or she is with the pen, the help of an editor is always needed.
There are 2 main types of testing – manual and automatic. In the first case, the tester proofreads the code, analyzes the user interface, and checks how convenient it will be to use your product. Automated testing is used for deeper code analysis, and experts use special tools. The primary purpose of automatic testing is to check module compatibility, protection level, and load, but the UE cannot consider this.
There is a relatively extensive list of internal factors; among the most important are:
- The development model was used.
- Regardless of which development model you use, the tester must choose the best strategy for this. For instance, if a software requirements specification (SRS) consists of a series of state transition representations, then the good practice would be to use state transition testing.
- Need for documentation.
- When developing software, specialists create special project documentation. It specifies the main functions that the product should use and what tools are used to achieve the goal. Also, experts consider the testing methods that should be used in advance.
- Set of testing skills.
- There are a considerable number of testing types, but when choosing, you must take into account the real requirements of your project. Following TestFort official testing website offers a large selection of experienced professionals specializing in manual and automated testing. They will help you choose the type of testing you need, as well as provide detailed advice on how to monitor your project in the future.
- Purpose of testing.
- You need to understand what goals you are pursuing during testing immediately: check the compatibility of modules, performance, user interface, and much more. The more accurately you can build goals and objectives, the better your result.
- The software testing life cycle model was used.
- Two main models are considered here, called iterative and sequential. Waterfall model as well as V-model are good references of sequences. The flexible model is an example of an iterative model. Such testing has short milestones, and fast delivery, so exploratory testing is required. In contrast, sequential testing provides a product at the end of the entire cycle, so more formal testing methods are used here.
As you can see, KPI in testing strongly depends on the main parameters of the software itself: program, website, mobile application, and much more. When compiling software documentation, specialists should consider which testing methods are best, depending on the selected functions and tools.
In addition to internal factors that directly relate to the project’s technical features, there are also external factors. These include:
- Before you start testing, you need to assess all possible risks. The more of them, the more documentation you need to draw up, and the more formal the testing will be.
- End users.
- When testing software, consider the end user’s needs, especially if it is developed specifically for banks, hospitals, and other vital institutions.
- Project deadline.
- If you’ve announced a product release for a specific date but don’t have time to complete full testing, then you need to develop a new strategy. Today, some techniques allow you to run tests faster, but you need to be prepared because they will not be able to identify all errors.
- Automated testing is more efficient when checking functionality or load; however, it is expensive. You can get by with manual testing if you are creating a startup with limited financial capabilities. It allows you to read the code and find apparent errors, understand how convenient your product will be for ordinary users, and much more.
Because there are many different x types of testing, you can choose the most suitable option, depending on your terms and budget. It is also necessary to take into account the real needs of users. For example, programs for the financial industry must have impeccable protection, so when testing QA processes and procedures, it is necessary to place maximum emphasis on security checks.
If you are creating your software, you need to think in advance about the testing methods we will use. It should depend on the features of the product itself, your budget, and time constraints. You need to seek help from experienced professionals who will develop a strategy and conduct complete testing in the shortest possible time.
