Automation testing is pretty obvious if considered to be anything in terms of software. The software can be considered as a Web App, Mobile app, fully-fledged desktop software and others. However, not everything requires automated testing. As it can waste the time and resources when not required.
To understand what Automation Testing is, it is the test that is done to check the expected result and outcome of the test. Also, we use this kind of testing so that we need not to do manual testing on a repetitive bases.
Now the question is Where to do – Web or Mobile.
For testing, we need a setup which returns results, both expected and the current result. For this, we need to have data, Since UI/UX can be changed without even testing the content. Although there are some cases when UI also needs to be tested.
This is the case with the UI/UX which has data-driven UI, we need testing there.
Data-Driven UI/UX testing returns UI with the data from the database or some other sources.
In the case of Web Development, the backend is returning the data and the data renders the UI. So the test is written here to check if we getting the UI that we expected or any different result.
Now in the case of Mobile App Development, the approach is quite the same here. Since an app is a complete software for mobile phones, we need to test the apps thoroughly before deploying it to the Play Store or App Store.
It also has UI testing, which are generally data-driven UI and is rendered when data is present.
For testing a Web/Mobile Development project, We follow the following methods:
- Positive testing
This type of testing checks the basic functionality of the product. This checks whether the app is functioning properly or not. For example, if the app has two different modules, but during the test, the module M1 fails to run due to some dependency error in M2, the test fails. So your test comes to an end here, and you need not to re-run the test to check the faults again. You can easily check out the bugs at the initial stage.
- End-End testing
This type of testing is done when the product has to connect with the backend service and has to return some data.
When doing this test, we consider all of the scenarios what can happen at what page.
For Example, you can consider a shopping website with pages like Login, Signup, etc. sends some data and get data in return. In this test layer, we can confirm that everything including the backend access is working fine.
- Functionality Testing
Functionality testing make sure your software/website/app is working fine and all of its features are working as required.
We can consider the example of selection of file size, file types etc.
- UI Testing
As explained above, the UI testing is important in many cases. For example, we can consider several UI components which has variable data requirements, like Calendar UI, need to be testing.
This test will make sure if the components are working as required or are failing indefinitely.
- Load Testing
Load testing, as the name suggests, is used to test the load handling capability of a database or a file server. For example, if we load around 100s of 1000s of data on a database, it might fail at some point, thus failing in the test of consistency here. So we have to reprogram the database to be fault-tolerant and more consistent in handling of large amount of data.
And now, to the end of the question. Automation testing is important in both Web Development and Mobile development, sometimes being heavily required, and sometimes it doesn’t.
