Cloud testing of mobile applications

Cloud-based mobile application testing is a testing strategy based on which test scenarios are executed in virtual environments located in the cloud. 

The strategy allows developers and testers around the world to communicate and connect to mobile devices using the Internet. In cloud environments, testers can access almost the entire spectrum of devices with different platforms, OS versions, network operators, etc. Applications can be downloaded through APIs or web clients. 

Testing involving real devices is expensive, so cloud testing is preferred. Simulators and emulators available in the cloud allow testers to do everything a real user would do (e.g., swipe, double-tap, zoom, rotate, etc.). With the help of cloud testing, it is also possible to identify performance issues.

Advantages of cloud-based mobile app testing

• Scalability.

Allows simultaneous testing on different devices and platforms.

• Efficiency.

Used to simulate real scenarios with real traffic. For this, shared resources are used, which are dynamically allocated in a flexible environment that allows performing tests quickly.

• Cost reduction.  

Allows for avoiding the need to purchase a large number of physical devices and infrastructure.

• Flexibility. 

Enables to quickly change configurations to test different scenarios.

• Availability.

The cloud environment provides the ability to test in a real network environment, making tools available from anywhere for both developers and QA. It also enables users to run automated test scripts on location-based machines with different time zones. This means there is 24-hour availability for running tests.

• Perfect for the Agile methodology.

Agile works with cross-functional teams that work in parallel, unlike traditional Waterfall teams that work in stages. By using cloud testing, every tester has the same resources at the same time, regardless of location. Therefore, resources are allocated in parallel, not in stages.

• Continuous integration.

Cloud testing makes it easier and more cost-effective to check the stability and functionality of an application. You can immediately understand whether the test passes or fails by looking at the results. Thus, cloud testing is the best solution for continuous integration.

Disadvantages of cloud testing of mobile apps

• Dependence on the Internet.

Testing cannot be performed if there is no connection.

• Not suitable for all applications. 

Some apps may require specific conditions for testing.

•  High bandwidth.

Cloud testing resources are available to everyone who has access to the cloud. So to increase the efficiency of the tool being used, high bandwidth is required. 

• Lack of backup and redundant tests.

Most cloud-based tools are not able to back up and save test plans, so it can be costly to re-run them.

• Lack of security.

When you upload your app to any cloud-based testing tool, you are exposing data, information, the app, and sometimes even the code. Although these tools are safe and secure, there is still no 100% guarantee that they will not be hacked.

• Frequent functionality changes.

If the app is not stable and if the customer changes the functionality very often, it is not recommended to invest in cloud testing.

• Tester remoteness.

An app can be tested by anyone who has access to the cloud where it is uploaded. But sometimes testers need to be physically present in the same place to team up and fix/verify major bugs. Developers may find it difficult to get more information about serious failures if the testing was done by an anonymous person and major bugs are reported in a cloud test report.

Testing types that can be performed in the cloud

The cloud can be used for almost all types of testing, from functionality testing to load and performance testing.

There are also specific tests that cannot be performed in some cloud-based automation tools. By choosing a cloud-based testing tool, you can cut your efforts in half as all the basic and important tests are run in the tool with interactive and informative test reports.

Common tests that can be performed in the cloud testing

What applications should be tested in the cloud?

1. Games and graphics applications.

Cloud-based tests for applications that require a lot of power and resources provide an accurate performance assessment. Also, the cloud environment allows us to use different configurations and extensions for better coverage. 

2. Apps with a large user base.

Perfect for applications with a large number of users, as it helps to see how well the product works under heavy load.

3. Global applications.

Cloud testing will help analyze how well the application adapts to different regional settings.

And what applications shouldn't be tested in the cloud?

1. Hardware dependent

Cloud testing may not cover all the specifics if the application is highly dependent on particular hardware.

2. Specific applications.

Some applications that have unique requirements or have specific functionality might require testing on certain devices.

3. Local-dependent applications.

If the application is highly dependent on local settings or functionality, testing in the cloud might fail to provide sufficient representation of different local conditions.

Cloud testing of mobile applications is gaining popularity in the software development industry. This testing provides the versatility and realism that are so important for high-quality mobile applications.

It is important to consider the unique needs and features of an application when deciding whether to test it in the cloud. In some cases, a combination of cloud and local testing might be the best solution. It all depends on the specific requirements and development goals.
