Software Testing Techniques and Tools

Nowadays, software projects are more complex than ever before. The software industry is growing at a very high speed and software developers must be up to date with new developments and opportunities in the software world to use the latest technology in the best way. So this time, I decided to talk a bit more about the testing part, which plays a crucial role in the construction of scalable platforms of great performance.

There are many types of business, but in software development, quality is essential for success. To guarantee this success, the testing function is vital. The software tests help the teams to evaluate the software with the requirements and information collected from the users and the product owner, simplifying the lives of the developers. We are big fans of the agile methodology and we believe that in order to correctly apply this methodology you need to do TDD (Test Driven Development) and CI (Continuous integration). The agile tests form one of the most important roles of the agile methodology. We believe that tests should not be separated from the development process, as is done with more traditional models. Software testing is a part of the software development process. And the tests must be written before writing the code to be able to identify the errors more quickly and correct them in the shortest possible time. The software test helps reduce the risks of development, time and costs.

There are still people, who prefer to save money in the testing process. And this is a big mistake!

Even though the initial investment may be higher, in the long term the maintenance of the platform and the development process is much cheaper. The software tests give quick feedback, so all lovers of the agile methodology use it.

We speak with our software development team and although there are dozens of different tests on the internet, we have underlined 4 that we believe to be the most important and essential to build software that works. You will also find a list of the best tools we use in our projects.

4 essential software testing techniques to build software that works.

  1. Unit test

Let’s start with the first and smallest of all – unit test. The unit test is applied to the smallest element of a system; each component is tested to ensure that it works correctly. It usually develops a single cohesive function. The function of the unit test is to analyze each small part and test that it works correctly.

The unit test is mostly used by agile developers, especially in extreme programmers, TDD lovers. However, unit tests are more popular today and other developers are starting to use it.

  1. Integration tests

The integration test is a logical extension of the unit tests. Two units that have already been tested and combined in one component and its interface are tested among them. A component, in this example, refers to an aggregate that is integrated in more than one unit; these are combined into components, which are added in order in larger parts of the program. The reason for the integration tests is to verify the functionality and safety of the components that have been integrated. Identify the problems that occur when the units are combined. This is particularly beneficial because it determines how efficient the tests are working together. Remember that it does not matter how efficient each test works, if they are not properly integrated. It affects the functionality of the software program. Further,

  1. Functional tests

The functional tests are based on making sure that all the features work from start to finish. For example, a test that the characteristics of a user are updated when the user clicks on the save button. Functional tests test a small part of the functionality of the entire system. It is applied to verify that the applications and functionalities of the software act correctly according to a specific design.

Functional tests are crucial elements to ensure the quality of the software product and confirm that it acts according to its functions as expected by the user. The tests are used to verify that the application, web page executes its functionality through an adequate response to user controls, a consistent user interface, integration with other systems and business processes, and proper management of information and search.

Before starting a project, we always make sure that we start working to create the best user stories; short, simple, desired characteristics and descriptive from a user perspective. The best user stories are the simplest and usually have a very understandable form:

  1. Performance tests

And the last one is the performance test. In software development, the performance test is a test practice that determines the performance of a system in terms of response and stability in a particular workload. It can also serve to investigate measure, validate or verify other quality attributes of the system, such as scalability, security, and use of resources.

Performance tests build standards of performance in the implementation, design, and architecture of a system.

It can be used to verify that a software platform presents the product owner’s specifications. This test shows how efficient software is. Check how well the software works under a maximum workload. There are several variations or subtypes of performance tests such as load tests, stress test, volume test and many others. These test methods ensure that what has been done has been done correctly; taking into account the different circumstances that may appear in the future.
