To begin configuring the Sauce Labs Mobile App in Provar, start by adding a new Browser Provider.

Navigate to the Test Settings view and click the Browser Providers tab. Then click the Add New button:

On the Add new Browser Provider screen, add a Provider Name and select the Sauce Labs Mobile radio button:

Add your Sauce Labs mobile server details to connect to Sauce Labs:

Once added, use the Test Connection button to verify the server details.

Testing Scope And Features

Both vendors offer cloud-hosted testing. Sauce Labs’ Continuous Testing cloud is designed to support all aspects of testing, using both simulated browsers and mobile devices and real mobile devices. BrowserStack supports functional testing, real-world condition testing and regression testing. Sauce Labs has more elements in its testing repertoire than BrowserStack, including analytics and performance, and users say its UX testing capability is more complete.

Both products require users to define how the test data maps to the GUIs involved, and users are generally comfortable with this process in each toolset. Users with specific interest in browser or mobile apps appreciate BrowserStack’s approach of different modules for different missions, but those who require both view the segmentation somewhat negatively, so it’s smart to know just what UI type the app uses.

BrowserStack has strong organizational features. Users can define teams, allocate resources by team, and — depending on the purchased plan — do parallel testing. With provided analytics, development managers can review how many tests are run and the pattern of testing, and whether the tests cover the full functionality of the UIs. Sauce Labs also has good team support and team metrics such as data on the rate of changes made, the number of changes and tests run.

What Is Mobile Application Testing

Posted Aug 11th, 2016

The number of consumer and enterprise mobile apps have grown exponentially over the last few years, leaving the end user with an humongous number of apps to choose from. But how does the user choose the app that will take up the precious space on their device? App quality is the key to any apps success and it can only be achieved through mobile application testing.

What Is Mobile Application Testing And Why Is It Important

7 Top Device Clouds for Mobile App Testing

App success can be measured by the number of downloads and the positive comments, as well as a rapid implementation of new features and bug fixes. Above all, not be underestimated, word of mouth. But how can you ensure any app success?

With mobile application testing.

This practice allows you to deliver better software and helps your app to be successful by testing its functionality, usability and consistency, growing your user base.

Testing is in fact an important part of every software development process and with mobile apps it has become even more important. The growing number of mobile devices is leading to a massive fragmentation of OS, screen sizes, variations of standard OS and more. With agile processes, software testing is performed every so often to assure the best possible quality. New features and bug fixes need to be released with short intervals, so users dont loose interest and new features should not bring new bugs. Testing becomes vital for an apps survival.

Real Device Automated Test Time Limits

By default, automated tests that are running on real devices in the Sauce Labs data centers can run for up to 60 minutes. However, that duration can be affected by other factors:

  • If the test is idle for more than 60 seconds, the test will timeout and end the session, so consider writing tests that do not include waits that may trigger this timeout. For Appium tests, you have the option to increase the idle timeout value to a maximum of 90 seconds using the newCommandTimeout capability.
  • If you are running multiple Appium tests concurrently on the same device, consider setting the cache ID to bypass the default device cleaning process and session exit between tests.

Using Automated Mobile App Testing

Sauce Labs empowers you to run automation tests using the test instrumentation you prefer, so you can achieve total digital confidence in your app’s behavior and performance on any mobile device.


While “mobile testing” can also refer to testing web apps within a browser on a mobile device, the Sauce Labs mobile automated testing documentation is predominantly addressing concepts and practices related to testing a mobile app designed to be installed on a mobile device.

Standard Requirements That Need To Be Tested

  • Usability
  • Performance
  • Edge Cases

Other important elements when testing mobile apps are the target devices which should be chosen wisely, usually between 10 – 30 devices and relevant for your target market. Those devices should include, based on territorial coverage, the most used screen sizes and OSs platforms and versions. All the information needed can be found online, starting from screen sizes and OS.

So, as you can see, there is a lot of work to do before actually start testing. We put together regularly the top 10 devices of different countries based on their territorial coverage.

An example of top devices used worldwide would include devices with screen size between 4.0 – 5.2 with resolution between 640 x 1136px – 1080 x 1920px . Next step is to look for the market shares based on OS and manufacturer. Android , followed by Apple share the market with a majority, with the majority of the Android devices running Marshmallow and Lollipop . The majority of Apple device run iOS 10x.

For easier selection, it would also be a good idea to find the different Android market shares based on manufacturer.

With these information you can go ahead and use websites like to filter out devices with the above mentioned characteristics.

Add Apple Sandbox Test Cards

Apple test cards can be found on Appleâs Sandbox Testing page.

  • On your device, go to Wallet. If you didnât set a passcode, Apple will show a notification.
  • In Wallet, tap the plus sign to add a new card. Use the card information on Appleâs Sandbox Testing page.
  • Prepare Sauce Labs. As mentioned before, Sauce Labs uses an enterprise certificate to install an app on public and private devices. But Apple Pay canât work with the enterprise certificate, so the app needs to be signed with the developer certificate. You need to instruct Sauce Labs to not re-sign the app when it is installed.

    Browserstack: Easy To Use But Integrations Lag

    BrowserStack offers comparable main features to Sauce Labs but focuses more on ease of use. BrowserStack also makes its integration with on-site hosting, testing and network resources crystal clear, which users find easy to set up. Development teams can combine local testing and cloud/remote testing and run it repetitively.

    The Live products from BrowserStack offer an opportunity to work with a browser or mobile device in real time, useful for developer and early-stage unit testing. The Automate offerings use Selenium for test automation, to suit all aspects of testing. The testing features are good, but users think that BrowserStack is slow to add features and tool integrations.

    BrowserStack users generally have a more favorable view of the platform’s documentation than Sauce Labs customers. Interestingly, as users build experience with the package, the advantage BrowserStack offers in documentation diminishes experienced users sometimes find the documentation to be superficial.

    Effective Mobile App Testing Using Appium

    Web Application Testing: Step by Step Process to make it Right

    Learn the essential concepts you need in order to understand in order to use Appium.

    Whenever I think about mobile testing my head hurts. You have a kabillion devices out there, in a variety of shapes and forms. Some are Android, some iOS. You have phones, you have small tablets, you have big tablets. Some use Wifi, others communicate directly to a telecom company on a network supporting 3G, 4G, 5G? Thats only the device we havent even gotten to the application running on the device. Thats another layer of complexity. How do you test? Do you put test code directly in your app, hidden behind some backdoor and then run test results to a log? If so, thats another of headache. Now you are supporting not only the app code, but the apps test code as well. As I said, it makes your head hurt.

    But, there I found a way to circumvent the pain. Use Appium.

    Appium is an open source testing framework that you can use to test iOS and Android mobile applications that contain browser based UI components, native user components or a hybrid combination of both. Not only does Appium allow native or web testing, under the covers the tool uses the Selenium driver technology. Thus, you dont need to reinvent the wheel in order get productive. If you’re familiar with using Selenium, once you understand some basic concepts, youll get up and running with Appium in short order. I know, I did.

    So allow me to share my experience with Appium at a high level. Heres the game plan:

    Lets begin.

    One Of The Biggest Shortfalls: Translation

    With almost 1,000 apps being added to app stores every day, there are many reasons why a user might choose one over another. Lack of language translation is one of the simplest issues, but lack of adequate testing of translation when its implemented is another. Having a good translation of your app for international markets , but dont forget other important aspects as well, such as:

    • Translating app store description text
    • Accounting for fonts and word lengths that vary by country and language
    • Improper font size for device sizes that are popular in each country
    • Color themes that have subtle meanings per country
    • Knowing UI standards per country

    With this level of competition, a testing strategy that includes expertise in each of these areas, for each region you plan to target, is crucial to success.

    Test Queuing And Concurrency

    What are concurrent test runs?â

    The number of concurrent test sessions in your plan tells you:

    • On how many devices your test scripts can be executed at the same time, in the case of automated testing
    • How many devices you can remote control at the same time, in the case of manual testing.

    If I run a test and all the devices of the selected model are “Unavailable,” how long will the test be queued?â

    15 minutes by default. You can increase it up to 30 minutes using a timeout capability. See See Test Configuration Options.

    You can also shorten it, but putting it to less than two minutes is probably a bad idea. At less than two minutes, you may see tests not starting because the session may not have time to be initialized.

    If I have a concurrency of five and I start 10 tests, will the Real Device Cloud queue five of the tests to run later?â

    Yes. The five other tests will try to get the requested devices for the next 15 minutes. Thatâs the default time — it can be increased to 30 minutes through a timeout command. See Test Configuration Options.

    Many Different Testing Tools

    Another obstacle for developers and testers is the choice of the right tools for mobile app testing. There are so many tools out there that it is impossible to choose from, unless you have a mobile testing strategy and you know exactly what you need to make your testing plan happen.

    Supporting Mobile Application Testing And Continuous Integration Using Appium In The Cloud

    Setting up an Appium Server in a continuous integration environment can be challenging. You need to make sure all the dependencies Appium needs are in place. You need to make sure that the emulators for the devices you want your application to support are wired into Appium properly. Also, when it comes to time to run a test session, you need to start a server instance that is dedicated to the device emulator against which your test is to run. Should a new device come into the mix, youll need to upgrade accordingly. As I said, its a lot of work.

    The easier way to go about facilitating Appium test support for variety of devices is to use a service such as SauceLabs. Using an Appium Service in conjunction with a CI a tool such as Jenkins is a pretty straight forward undertaking. Figure 7 below shows the concept behind the process.

    Figure 7: Jenkins works well with an Appium Service to test application code in a Continuous Integration environment.

    Listing 3 below is a Java test that shows the modification required to have a cloud based application artifact tested against an Appium instance running on SauceLabs.


    Listing 3: A Java test that uses a cloud based application artifact and a SauceLabss Appium server instance

    As you can see from the diagram above in Figure 7, using Appium as a service for CI is a pretty straight forward undertaking once you get the parts configured correctly.
