It's 2021, where everything has a smartphone app. Be it social networking, retail, productivity, or health, mobile applications and their users have increased significantly. Developers can guarantee that their consumers get the optimum experience possible by doing quality testing with an automated mobile app testing platform.
The world is firmly partitioned between Android and iOS users; according to Statcounter's study, 72.48 percent of the world's population uses Android, while 26.91 percent uses iOS. To develop mobile applications that are compatible with various devices, extensive mobile testing is required, as people consume applications on a range of devices running different Android versions. That's where mobile application automation testing comes into play.
Types of Tests That Should Be Automated
Unit testing is critical for an application since it verifies the application's smallest pieces or components. During unit testing, we test an individual module in isolation. These are short tests in which the input is passed to the app's little unit, and the output is compared to the expected values.
Since they are simple tests, they can be run fast and efficiently. However, unit tests are sometimes overlooked when it comes to application testing. When used appropriately, they significantly reduce errors by catching issues at the unit level.
As a result, unit tests are excellent for automation due to their rapid execution and large quantity. Typically, unit tests are used to verify that a class meets a specified requirement so that the class is self-contained and irrespective of other classes. Unit tests describe the testing at the unit level so that when we make code changes, we already know which code may cause difficulties.
User interface testing is critical to the success of any mobile application, whether it be Android or iOS. In UI testing, we examine the application's visual behavior during user interaction. On the iOS app, all iOS-based motions, interactive features, screen rotation, textual input, and buttons should operate as expected. Unlike unit tests, which are done independently, UI testing examines the integration of various classes.
We should automate user interface testing for the following reasons:
1. Saves a lot of time –
Manual testing is time-consuming, but we want to spend that time productively, such as exploratory testing, ad-hoc testing, and so on.
2. Documented testing –
With automated testing tools/frameworks, it is much simpler to detail the whole testing process with images, reports, test results, and test run time, among other things. These published statistics can be used to optimize testing and application performance.
3. Testing on actual devices –
These automated testing technologies enable the execution of test cases on thousands of real devices. Especially in the case of mobile application development, we'd want to see test cases executed and the program evaluated on actual real-world devices.
4. Parallel testing –
Automated testing technologies enable the simultaneous testing of a mobile application on numerous devices. This allows us to complete testing activities more rapidly.
It verifies an application's interoperability with various devices, hardware, OS versions, networks, operating systems, and browsers, among others. It will verify that the application version is compatible with previous hardware during backward compatibility testing.
Similarly, it guarantees that the existing application version is compatible with any new patches or upgrades to the mobile app during forwarding compatibility testing.
Today's software industry adheres rigidly to Agile and DevOps practices. Without these, we cannot consider software development, and it is critical that mobile app testing follows suit. Continuous Integration enables early feedback, rapid delivery, and improved quality without the need for manual intervention.
Continuous testing involves the assistance of automated technologies such as GitHub as a repository, Jenkins as a continuous integration tool, and XCTest for unit testing. By utilizing powerful automation across the application development cycle, CI/CD enables the delivery of applications more often.
Unit tests are designed to execute automatically whenever a computer program is uploaded to the repository. Without automation tools, we cannot consider CI/CD. For instance, automation may simply take care of the security of an application by certifying the entire application with the appropriate certificates and rights.
Historically, regression testing has been the ideal choice for automation throughout software development. We don't want our program to fail to function properly as a result of fresh additions and feature development. According to Marketing Charts, customers have spent 28 billion USD on mobile applications by the third quarter of 2020. Thus, how can we assure that the app remains intact and in excellent condition? By automating regression testing following each modification.
By automating the regression tests, we can execute them without human involvement throughout the overnight cycle when everyone is off work. This assists in lowering the testing time and enables the product to be delivered more quickly.
Developers may utilize a variety of automated testing frameworks and tools for smartphones to accelerate the testing process and provide a high-quality product to end customers.
