On the other hand, automated testing excels in repetitive, high-volume test scenarios, ensuring efficiency, consistency, and quicker feedback. Combining both approaches optimally addresses the dynamic testing needs, leveraging the strengths of manual testing for qualitative assessment and automated testing for repetitive, time-intensive tasks.

Ultimately, the decision hinges on the project’s nature, timeline, and the balance between human insight and the efficiency of automation.

Step #2: Stages of Mobile application testing

Let us now learn about the various stages of the mobile application. Here is the list:

1. Documentation Testing

The beginning of mobile testing takes place during documentation testing, the preparatory stage.
Even before the development of the app starts, the testers are handed over screen layouts, navigational charts, and other requirements that are obscure in the design.
In this phase, you need to analyze the requirements for wholeness and discrepancy. All the discrepancies found in this stage are required to be resolved before the development begins
The documentation phase marks the creation and analysis of requirements (specification, PRD), Test Cases, a test plan, and a traceability matrix.

2. Functional testing

It helps you test whether your mobile application works as expected and in accordance to the requirement specifications. While you are performing functional testing for your app, keep the following factors in mind:

  • Business functionality of your app like banking, social networks, ordering and delivery of food, education, tickets, the game industry, etc.
  • Target audiences like companies, students, entrepreneurs, etc.
  • Distribution channels like Google Play, direct delivery, App Store, etc.

The basic validations that you need to test in functional testing are:

  • Installing and running the application
  • Fields testing
  • Business functionalities testing
  • Interruptions testing
  • Constant user feedback testing
  • Update testing
  • Device resources testing

3. Usability Testing

Usability testing ensures that your application offers convenient browsing to your customers and creates an intuitive interface that abides by industry standards. It promises fast and easy-to-use applications. The usability of your application is judged based on these three basic criteria:

  • Satisfaction

Why Appium is Impeccable in iOS and Android App Testing

Since mobile testing involves testing the applications across different devices and platforms such as Android and iOS, the task can become quite hectic. Thankfully, there is way out of this, and that is to use the mobile automation tools. Though there are many mobile automation tools available at present, Appium proves to be the most effective and accessible.

app testing

Appium is flexible, feature-rich, scalable, and hugely helpful. And learning it would ease the job of every mobile tester. Well, if you are curious to know about Appium and its features, we can help you with that by providing necessary details.

Appium – The Open Source Mobile Application

Appium is just an open source mobile application for mobile automation. Appium supports native, hybrid, and web application automation test across physical devices including both an emulator and stimulator. It even enables cross-platform app testing where its real beauty lies.

Appium let the user write tests for multiple platforms including iOS, Android, and Windows Phone using the same API. It means that you could write a test for iOS and use the same test for Windows Phone and Android.  It saves time and aids the software tester to reuse a large number of codes between different test suites.

Another great feature of Appium is that it has no dependency on Mobile device OS. It is because Appium has a framework or wrapper that could translate Selenium Webdriver commands to UIAutomation or UIAutomator commands based on the type of device. Furthermore, Appium supports almost all languages which have Selenium client libraries.

Appium even showcases a neat feature that can automate without recompiling the app. It means that the user doesn’t need to have access to the application code to work with Appium. Whereas, other mobile automation tools like Frank and Calabash demands the user to be aware of the app code to be able to work with it. Thus, you could test the same app which you will be going to submit to the app store.

A bonus comes along with the philosophy on which Appium is built. The theory follows four tenets which will be discussed below.

Appium Philosophy and the Four Tenets

No automation or recompiling your app – As we have read earlier, Appium doesn’t require an extra agent or an app code to work. Therefore, the user doesn’t have to recompile or modify the app to automate it.

No requirement of a specific language or framework – Appium supports all languages when it comes to writing tests. Ruby, Python, Java, Node.js, Objective, PHP and you name it. Users wouldn’t have to learn a new language to work with the tool.

No reinventing the wheel – A better tool for mobile application shouldn’t reinvent the wheel when it comes to automation APIs. Appium uses WebDriver API, and so there is no hassle of reinventing the wheel by introducing an entirely new API.

A framework should be open source and practical – Appium is freely available to all the users and can be easily modified as per the user’s requirements. Furthermore, Appium is completely practical and real in spirit.

Appium and the Way It Works

Appium is an HTTP server written using a Node.js platform. It drives iOS and Android session using WebDriver JSON wire protocol. Once Appium is downloaded and installed on your device, a server is set up on the machine that gives REST API the required exposure. Later, it receives connection and command request from clients and takes necessary actions to execute the command.

Appium responds back using HTTP responses and uses mobile test automation frameworks to execute the request.

Prerequisites When Using Appium

Before you get started with Appium, you are required to install a few of the below-listed applications to work efficiently with Appium.

  • Android SDK
  • Java Development Kit
  • Eclipse
  • TestNG for Eclipse
  • Selenium Server
  • Appium Client Library
  • APK App Info on Google Play
  • Appium Desktop

Limitations of Using Appium

The most significant limiting factor of using Appium would be its inability to synchronise with AUT accurately. To put it simple words, while the automation tests are running, it may take some time for the action to complete. It may be waiting for some element to load or get ready so that the user can move forward to the next step. However, Appium doesn’t handle this situation diligently. One could put a “wait command” to overcome this delay. Nonetheless, this cannot act as a permanent solution and can turn your automation test to run slowly. Tools like Espresso and EarlyGrey could efficiently take care of situations like this.

Again, Appium is quite a tough tool to handle when you are a complete beginner in the process. You will also require a Mac system to run iOS tests, and iOS apps cannot be automated on Windows or Linux systems. This is due to the reason that Appium requires Xcode for iOS automation which is Mac-only at present.

Appium can again be a tough nut to crack when users look at it from the scalability perspective. Due to the technical limitations, users can only execute one test at a time Mac. This can be a great set back when buying Mac and buying multiple Macs to solve the situation can prove to be costly. Nonetheless, the only way to address this issue is to take aid from mobile cloud services such as SauceLabs.

17 Different Approaches to Comprehensive Mobile Testing for iOS and Android Apps

People are not so positive on QA even if they know how important it is for a software nourishment. A step of testing is avoided more often than not to save on budget.
app testing
Remember, branded products always come with standard price; but, why….? Because of the quality they assure.
We all have heard the proverb “all that glitters is not gold.” Likewise, no matter how beautiful, trendy and charming your application design looks, it is not going to bring anything good
if it doesn’t provide the expected quality.
As a user, you would definitely go for a better option if the expected application goes on loading for more than 5 seconds. Believe me, some of the users won’t even wait for 2 seconds. A book series can be written about the customer dissatisfaction experiences on the applications. Remember, a user once lost is lost forever.
The purpose of testing is not always about finding the errors, but, it is also to make sure the application works properly.
Does it functions well?
Is the user satisfied?
Does the application work as developer expected?
The best stairway to perfection is always questioning the possibilities. Testing is a mixture of techniques and methods; there is no simpler way to make sure the working status of an application. For every execution process, we need a plan.
Here, we are going to discuss about 17 different approaches that can be applied for testing iOS and Android apps.
General strategies
1. Let the QA tester belong to the core developing team.
Generally, companies have a waterfall way of processing an application. In that case, testers will get busy with in a week of starting the project. But, in the agile method of working, QA is an important part, which the team considers as an essential ingredient for the success of the project. When a tester gets involved, he/she will be well aware of the development taking place and be sure about the part in which improvements are needed.
Also, approach it, considering the design and user expectation.
2. Ensure the test scripts
There are people who think, ‘QA is not that important, let’s just ensure performance’
Can you believe that people actually think like that even at this time of hectic competition? Also, it’s not as simple as testing everything casually. A pure, complete knowledge on function should be there and the required data should be provided to the tester for a complete logical testing.
The product team has to make sure that the scripts provided are understandable by the tester.
It should be made simple for any programmer to understand.
3. Functional testing
· Do the features work?
· Can user complete the task?
These are the two main questions we need to find the answer for explaining functional testing. The tester will work along with the procedures of the application so that he will understand the performance and the flow of to and fro pages.
4. Unit testing
Unit testing works in relation with codes. Usually, developers do this. Codes are mantled, separated into different parts called units and tested thoroughly. The unit referred here can be a code module or a function.
5. Performance testing
Testing is all about improvisation. So, performance testing is done to make sure that no delay in performance of application happens as the result of improvisation.
Here, the testers monitor the speed and how well the application responds to features. Time consideration is also a factor involved in performance testing along with
· Data consumption
· Battery duration
· Space consumption
· Navigation
· Network coverage etc.
6. User acceptance testing
The term ‘User acceptance testing’ is a wrong term because we don’t have an actual user. Instead, we select a group to conduct the test.
We can’t just go on and ask people to take part in this session since it takes time. So, we seek the help of our colleagues. A group from inside the company, who may or may not be a part of this application development, will take part in this testing.
Usability testing is usually considered as a final step in the case of websites or applications,
Steps followed in usability testing are:-
1. Planning
2. Selection of group
3. Explaining what is expected and what is not
4. Introducing main scenario
5. Testing specification, bugs
6. Sign off
7.Manual Testing  vs Automated Testing
Machines are faster; that’s why it is better to make QA tests automated. It is because computers can find anything that does not work, faster than the human brain can.
It simply saves money, time and provides more accuracy.
Yet, not every QA task cannot be completed by computer. Sometimes issues occur, that are too awful for software to complete.
8. Load Testing
Load testing is a lot of work. It is checking the user capacity that an application can hold to make sure that the application loading will not be exhausted in an expected number of user logins.
automation testing
Basics of load testing
1. Record the traffic
2. Replay the request
3. Analysis
9.Regression Testing
Regression testing is like marvel movies. Interesting, huh?
The hero gets unusual power, use it stupidly, but, at the end, he realizes that he can make big changes.
Even a small change in code can error the whole application. So, regression testing helps in ensuring that the changes made doesn’t affect the flow of the application.
10. Device Testing
Mac and Windows are usually considered for device testing,
That’s something cool about device testing. There are over 24,000 models that exist in Android itself.
bird eye view of android screens
This is a bird eye view of android screens that presently exist.  (source)
Deciding which screen size application is optimized is more important here. Having a clear company policy will help testers to ensure that the rules and test selected rather than all supported devices.
11. Testing Interruption
Interrupt conditions are mainly the interruptions that occur while the applications are running.
It includes incoming/outgoing calls, text messages, notifications etc. In the cycle of applications when disturbances happen, interruption testing tells applications how to behave properly.
In short, interruption testing is just like teaching good manners to a child, “behave boy” 🙂
12. Crowd source Testing
Crowd sourcing is simply recruiting a specific group through a third party. When a developer wants to test a product, he contacts any agency that provides a collective group which is suitable for testing product. This agency will collect the record and give the developer a result.
In mobile application, crowd sourcing is becoming a latest trend.
The agency and the group get paid according to the bugs they find.
13. Connectivity Testing (Network)
Since digitization is taking over the world, we are provided with plenty of connectivity carriers.
We may run out of daily supplies, but data connection! Never.
So, what the tester has to make sure here is, how applications respond to various data carriers, especially, 3G 4G, LTE.
Testing on popular data providers would help to ensure the performance of applications since they will be the widely used networks. Also, testing how applications work when data loss or weak connection happens may help.
14.Emulator Testing policy.
There are many emulators now that developers use effectively to test any application. is the most popular among them.
In a tester’s perspective, you would want experts to test in one or more devices, on most popular versions of Android and iOS but testing in different devices, screen sizes, and OS versions can be done through emulators in order to save money and time.
15. OS version: Testing and Support
iOS and Android have significant OS versions in existing markets. Also, we have to agree that iOS is better than Android. It is the main reason why many companies are advised to develop applications in iOS initially.
Android doesn’t have complete power on the available versions provided for the users. But, apple has complete power on the users and provided versions since they manufacture both software and i Phones.
16.UXA Testing
UXA stands for user experience assessment which takes an account of skills, methods and tools used to identify how much aware the user is about the application.
UXA is categorized into three:
1. Implict
2. Explict
3. Emotional/Creative assessment
Various reasons can be pointed out for why developers always fail to replace the functionality as designers outline it. The variations that occur between UXA and software may be too small but noticeable. But, the eye of a good tester should be like a hawk, catch prey at instant.
17.Security Testing
‘According to 2017 application security report published by cyber security ventures, 111 billion new software code lines are being developed every year
Hope you all understood what we are going to discuss now.
One of the main reasons that security testing should be done is to secure user data. Whatever data user provides should be encrypted and should never reach in bad hands.
That’s a duty, moreover a responsibility. Data leakage is an issue that happens commonly. Therefore, make sure that the data transfer is done through proper channel.
‘It’s a wild world out there’.

5 Conditions to be Added in Your Mobile App Testing Checklist

We can see developers setting new trends with exciting mobile applications every minute. But, this large number of apps leaves the consumers or the users in doubt, in terms of choice and their working.Therefore, app developers have mobile app testing or QA kept in top of their priority list so that their mobile applications are the best and defect free.
mobile app
We all know what mobile application bugs can do to mobile devices. An average mobile user will not prefer bugged applications in his/her device Therefore, in order to make it perfect, the mobile applications are tested.
Before you start testing, here are some key points to add to your checklist:

How will the Mobile Application Testing Service Market Fare in the Next 10 Years? [2016-2026]

1. Performance

The performance of app focuses on mainly two things:
working speed of the app and the responsiveness of the application, the CPU of the device, memory usage in SD card and in device and the battery drainage.
Even a minor or major weakness in the network connection can affect the performance strength of the application. This is a kind of device versus application. So testing focused on the Wi-Fi connection or network availability can help to improve these areas of crashes.
This also covers the amount of data used by the application. This is one of users favourite too. Performance is merited on the basis of how well applications behave on the device.

2. Interruption

Bugs are well known to interrupt working of devices. While the app is running, normal interaction is interrupted by different kind of external events.
This includes pop up alert like alarms, calendar, notifications, incoming /outgoing voice calls and text messages. Among these the incoming/outgoing calls are the most important kind of interruption caused.
Sometimes, this can affect the working of other apps in the device too. This is almost common for every application. Clearing this defect before launching the app in the market can add to its efficiency.

3. Device Integration

Integration of the mobile application with the device is significant.
Here the applications have to merge with all the settings, configuration, alignment and in built applications of the mobile device such as screen resolution, screen orientation, OS, camera, audio, GPS service etc., It is very important to know how an app works on specifications like your location, video and camera.
Expected results may vary according to the specifications of the mobile.
Response of device to the gestures can also be included and how the device responds should also be counted.

4. Installation

Installation is the part where the tester should look for the process of installing and uninstalling and the properties of updating.
Sometimes, testing of installation in the application is not done completely.
There are a lot of things to consider while testing the installation of a mobile application. Initially, we have to categorize the end users. The target audience have a relationship with the process of installing and uninstalling the application.
app testing
Also, the experience can vary for the first time users of the application. The process of updating the installed application has to be taken care of. The main question that arises here is whether the updated version of a mobile application is supported by the device?

5. Network

Testing on network deals with the poor or weak signal, quality loss and data transition.
Applications that don’t need network traffic after the installation wouldn’t be much affected. The main course problem with the application that requires network data for further working is that, they have a tendency to consume a large amount of data. MB. Messenger applications are one among these.
Battery drain can also happen while in-app use. Gaming apps having multi-player specifications and applications like sound cloud where user can listen to music online can cause huge battery drainage.

Limited Testing Begins for Android’s new ‘Instant Apps’

Last year at the I/O Conference conducted by Google in San Francisco, a new concept was introduced – ‘Instant Apps’. These applications can be used with a single click on the respective URL links. Users are not required to install the applications from the app store.

Temporary loading will be made rather than downloading the whole app from the store and installing. After one or two trials has been made, if the needs the app for further use, he can download it. This way, uses need not install apps to test if they actually finds it useful.

mobile app

About half an year after Google has announced Instant Apps, few selected apps are now ready to be tested. Fully functional Instant apps will not be available to the users yet. They will get a limited version to test out the functionality and provide feedback as mentioned in Android developer blog

Instant apps of BuzzFeed, Wish, Periscope and Viki would be the first ones to be tested. An Instant app gives the speed of a web page and works like a native app. According to the android team, other developers won’t be able to join in the initial stage. But can can be part of the wider SDK release if they apply here

Instant apps are expected to put an end to the massive consumption of data and storage in users’ smart devices as google themselves were claiming at the Instant App announcement event.
