There are various types of testing that may be used by software testing companies in Dubai, to ensure that the changes in the code are working as expected.  No two testing methods are the same, hence let us examine each one of them in detail.

Unit Tests

Unit tests are considerably basic, closer to the root of your application. They comprise of testing individual methods and functions of the classes, components or modules used by your application. 

Integration Tests

Integration tests focuses on verifying that the various modules or services used by your software function seamlessly. For example, it can be testing communication with the database or ensure that the microservices work seamlessly together. These types of tests cost dearly to run as they require multiple parts of the application to be working.

Functional Tests

Functional tests centers on the functional requirements of the software application developed by the software application company in Dubai. They only check for the final output of an action and do not check for the interim states of the system while the action is being performed.

There is much confusion centered around integration and functional tests as they both require many components to interact with each other.  The disparity between the two is that an integration test may simply check if the query to a database can be carried out whereas a functional test would require a specific value to be returned that meets the expected requirements.

End-to-End Tests

End-to-End tests mirrors a user behavior with the software in a comprehensive application environment. It reviews the various user workflow as intended. It can be as simple and plain as loading a web page or logging in or much more complex situations like checking for email notifications, online payments etc.

End-to End tests are highly effective, but they are high priced to perform and can be easy to maintain when they are manually done. It is suggested to have a few vital ends to end tests and depend more on basic type of testing (unit and integration tests) to be able to swiftly identify breaking alterations.

Acceptance Testing

Acceptance tests are formal tests performed to check if a system satisfies the expected specifications. They require the complete application to be functioning and concentrate on user behaviors. But they can also do more than that and can measure system performance and discard alterations if the specifications are not met. 

Performance Testing

Performance tests verify system behaviors when it comes under serious pressure. These tests are non-operational and can have the different forms to grasp reliability, stability, and availability of the platform. For example, it can be watchful of response times while executing large number of requests or examine how the system behaves with a considerable amount of data.

Performance tests are inherently quite expensive to implement and execute, but they can make you realize if the new changes are going to downgrade your system.

Smoke Testing

Smoke tests are elementary software tests conducted in Dubai that check the basic functionality of the application. There meant for swift execution and their goal is to ensure that the major features of your system work smoothly as expected.
