What is Software Testing?

The software test evaluates the correct functioning of a computer program.

Digital applications and tools have multiplied with the rise of the internet to the general public and the arrival of smartphones. The market is considerable and growing. Brands compete with each other to attract as many users as possible.

So the major challenge for brands is to retain and convert visitors. And for that, you need smooth interfaces and a great user experience. But most of all you need a bug-free app! Software testing, including mobile application or website testing, is the solution to chase bugs.

Definition of software testing

Software testing is therefore an integral part of the development and design phase of the digital product. In IT jargon, software testing consists of testing an interface or a product delivered by developers and tracking down any errors found in order to correct them. It therefore allows the bugs in the product to be reported. The main goal is to identify bugs within a set time frame before the product goes into production.

The 4 levels of software testing :

Unit Test

  • Unit test: this is a piece of code without logic implemented by the developer. It allows to validate the correct functioning of a component (and not a functionality). Moreover, it is also called component test.
  • Integration test: this is a test that verifies the proper integration of components between themselves to check if the whole works properly.
  • System test: A step that verifies whether the system conforms to the required specifications. At this stage, it is possible to run end-to-end tests. The test campaigns can bring up inconsistencies in the product.
  • Acceptance test: Final stage of the test. The product is delivered and ready to be deployed in production. The business must verify that the developments meet business challenges. The product must meet the needs of the users.

What is manual testing?

Manual testing is a process of manually searching for bugs in a website or mobile app. The test plan is executed by testers. With this method, the testers put themselves in the users’ shoes. The tests are executed on different configurations (desktop, mobile, tablet). The execution of the tests calls upon the curiosity and experience of the tester to try to find capricious bugs.

What is the advantage of automating tests?

Any feature tested twice manually is already one too many! Indeed if it works, asking a tester to replay tests on it at each new delivery is time-consuming. And it is also counter-productive.

Automating non-regression testing does:

  • save time.
  • improves productivity
  • Ultimately saves money

So test automation consists in performing non-regression tests following the delivery of a new version of a tool or application. The testers are thus focused on testing new functionalities.

In agile projects, and particularly for e-commerce sites, the implementation of automated tests can be a prerequisite to meet development objectives.

Saving time and money through testing

Today’s brands must be present and existing through digital tools. The fear is not to succeed in this passage which seems unavoidable to survive in the competitive market. The term bug is the challenge of the test, but also the threat of brands. The slightest malfunction can have serious consequences with a direct impact on turnover. Omitting the test phase during product development is a serious mistake that can be very costly. And unfortunately, many companies do not have the reflex to integrate or use it.


Today, thanks to an awareness of its necessity, the testing business has developed strongly. The integration of testing in the development cycle ensures the release of a quality product and maintains it during updates.
