Be sure that your application will work fine on the cloud with testing

The bigger our application gets, the more difficult it becomes to manually test it. This is why it's necessary to automate tests on applications – to speed up the time dedicated to this task and thus increase the speed of delivering value and new functionalities.

There are different types of test, but in this section, we will focus on the following:

• Unit testing: Tests that are performed on a particular component that performs a single action, to verify that the task is successful.
• Integration testing: Tests that are carried out between two components to verify that the connection between both components works correctly.
• Load testing: Tests that are performed on one or more components to determine the maximum call capacity that the application can support.

Each of these tests is important to ensure that our application functions properly, but some tests require greater implementation...
