Software Testing for Developers

Why do we Test

How secure would you feel using a system that has not been tested?

Let’s say that you intend to buy a car, but no testing was done the engineers worked on the car solely based on their experience.

How would you feel about using the car?

That’s why we test software to give a better sense of quality to the end-user of the software.

Integration Tests

Unit tests are great as they test a unit of the application, however you cannot be sure your system works if you rely on unit tests. Integration testing helps validate how components work in integration with external systems. The purpose is to detect faults in the interaction between integrated units.

End-to-end tests

In end-to-end testing, the whole application is tested in a real-world scenario such with interaction with the database, front-end, network, hardware, and other applications. This can involve several components of the system working together, such as the database, user interface, network, and APIs.
