The main thing in the testing process, of course, is the developer. When writing a test, the developer begins to understand the product requirements better. By clarifying some points when writing tests, the developer makes his code more stable and eliminates the simplest errors that he might not have noticed before.
When the new module is "covered," a qualitative check is carried out to ensure that the main and new cases that appeared in the logic with the advent of new functionality work. This will confirm that the changes that appeared in the application did not break anything.
We often resort to the TDD approach in development. TDD (Test Driven Development) is a test-based development. Such tests are immediately implemented in the code; they are written by the developer.
Let's take a simple puzzle. We need to make a form in which we enter the age of the cat and its weight, and in return, we get how much food the cat should eat per day. How to approach this task using the TDD approach:
- We are writing a test in which we verify that the getCatFood () function returns the desired values in different situations.
- Check that the tests have fallen (no code yet)
- We write the function code very merely - so that the tests pass.
- Check that the tests passed.
- At this step, we can think about the quality of the code. We can safely change the code as you like because we have tests that will confidently say that we were mistaken somewhere.
- Repeat all the above steps.
In our team, test cases based on user experience are most often the project manager.
A test case is a set of steps that you need to follow to ensure that the product has no errors and that it works according to the requirements. This includes the functionality tested and the testing method. There are different methods for making the test, each of which reveals the disadvantages of a certain type.
In testing, we like to use Selenium - a software library with several products that simulate user actions. A separate plug-in of this product can even record actions in program code, which will then be convenient to work with already in the developer's environment.
There are a large number of tools that allow you to analyze and increase the coverage of product tests, add new tests for specific cases, and get rid of duplicate tests. Thus, we can ensure the stable operation of the entire system and satisfy the customers and clients.
