Mobile App Testing Best Practices, Tools and Resources

Know More About Mobile App Testing Best Practices, Tools and Resources


Mobile application testing is considered as one of the important term or the part of software testing, as it is used to verify and validate the overall functioning of the mobile apps. Day by day, we see the drastic growth in mobile app development, as each day, so many mobile apps are developed, which could be for Android or iOS.

Mobile Apps Testing

Testing any mobile app is a demanding task. This is one process that requires a tester to go through a series of devices for testing the mobile app. The devices available in the market are the best ways to understand and perform the testing process for getting an ultimate app. In the process of mobile app testing, the tester needs to track the performance of the developed app across a number of handheld devices having a variety of operating systems and then they may also vary in their screen sizes. It is highly expected that the app should be safe and deliver the flawless performance throughout. This is the reason that the deployment team implements an app only when it has been certified and completely tested.

Well, before learn more about mobile app testing, you have to decide which tests you want because there is two different kinds of testing:

Bug Testing:

A company will test your code in order to find all the bugs in your app. Why do this type of testing ? You just want to be sure your app will work perfectly. If you need more information about it you can try Services | StarDust blog. They provide webinars, blog article and other resources.

UX Testing:

This is very different, because the company will test how your client will use your app. For example, I work for a startup called Fepection (Page on ferpection.com). Because we believe, no one can be better judge than real people who are possibly your client, that's why we do this kind of testing with our own community of testers. They give us feedback about your app, if it's seems slow to them or didn't understand how the purpose of a part of your app.

Both of this type of testing are really useful, Bug testing will give you an answer to the question " Is my app technically works". UX testing will give you an answer to the question "Does my app fit to the needs and habits of my clients". And when the time of launching your app comes, you better have answers to these two questions.

As software testing is moving towards automation, most of the software testers as well as QAs are switching themselves from Manual testing to Automated testing. Today, Automated software testing is considered as one of the most trending term in the field of software testing, as it is considered as one of the efficient as well as effective software methodology, making the overall software development/testing life cycle better and taking it to some different level.

Mobile test automation provides various test solutions, which help you to verify and validate the overall functioning of the mobile apps.

The best way to start mobile app testing


A beginners guide
If you are testing your app for the first time, the key thing to take into account is what you will be testing your application on. Depending on whether your app is built for Android or iOS there will be a huge range of devise/version combinations which will effect the functionality of your application. Try to get you hands on as many devices as possible, or rope friends in to test with you on their different devices.

After that, there are a few types of testing which would be most beneficial. Make sure you have a spread sheet, or tracking system to hand to log all your results. Be sure to always log the device, version and network connection which are relevant when you are testing, there are also other variables to watch out for such as battery life, other apps open in the background, what environment you’re in.

Top notch app testing is crucial. However, it is difficult since device fragmentation is a major issue with thousands of Android devices on the market. Even iOS is not entirely immune from this issue. Between all of the different “iDevices” currently supported, there are over 30 different iOS device models on the market today. Throw in multiple languages for different countries and you can see how the test matrix is daunting to say the least.

Taking a multi-pronged approach to testing helps to make the overall process more manageable, thorough, and successful. Take a look at three key steps to addressing the challenge of delivering high quality in a mobile world, as well as a new Pivotal Cloud Foundry microservice to help streamline the process of distributing test builds.

The best way to get your app our there is to literally get your app out there!

Get an app test going, then: 


1) Look for people with different demographics to help get an equal representation for your app testing phase.

2) Design questions catered towards enhancing product features. Are some of your app features necessary? Or are they simply an add-on? What makes your users want to refer your app to others?

3) Increase exposure for your app! Post these app testing on local classified and odd jobs apps like us, sending notifications to local people, while negotiating prices!

4) Test Driven Development; Testing early and often is critical for creating high quality apps. This helps catch bugs early in the development process, fixing minor issues before they turn into expensive problems and require tedious debugging later. A great way to achieve this is with Test Driven Development (TDD), one of the key concepts within the framework of agile development methodologies.

TDD is a reversal of the traditional approach to software development in which you write code, then write the automated tests for that code. TDD instead involves initially writing an automated test for a given feature, then coding the feature itself and ensuring that it passes the test.

This methodology has been shown to not only produce higher quality software but increase programmer productivity as well. It ensures that all code is covered by at least one test, which raises the baseline of quality. Beyond that, it encourages developers to focus on actual use cases throughout the development process and can reduce extraneous code. The net result is better quality software, delivered faster.

5) Automated Testing: With the myriad devices on the market today, you’ll want to automate as much as possible. This involves executing test scripts on devices, and it is particularly useful for regression testing and smoke tests (simple tests to ensure the app functions at a very basic level) because these are generally repetitive and time consuming to do manually.

There are many tools available for automated testing and several of them require the use of rooted or jail broken devices. We recommend avoiding those since rooting phones voids warranties, opens security holes, and even changes the behavior of the device being tested. Don’t waste time testing on devices that are not set up for their legally intended use.

Automated testing saves significant time and money by allowing you to run tests on many devices simultaneously and quickly. Since machines never miss a step, leveraging automation reduces risk of human error throughout the testing process. You can read more about requirements, goals, and solutions for automation testing on mobile in this white paper from Pivotal Labs.

6) User Testing and Automated Distribution:Despite the advantages of automation, it doesn’t address everything. User testing is still required in order to cover the unexpected aspects of human behavior that happen in real life. It is also critical to obtain valuable insights about how people actually use your app.

Once you’ve completed the automated tests, it’s time to put your app in the hands of real people, starting with the QA team and continuing with test user groups. You’ll want to stick to this “order of operations” in order to catch and fix the most basic issues before bringing your app in front of your most valuable testing audience.

Getting a pre-release mobile app in the hands (or pockets, as it were) of users can be a painful process. It often involves emailing a file, dragging/dropping it into a desktop application, and syncing it via cable to the device. This can especially be a nuisance for typical non-tech savvy users who don’t do it every day.

The challenges with user testing process don’t stop there. Keeping tabs on test user groups for different apps and making sure everyone has the correct versions of the correct apps is another burden for mobile development and QA teams. Using a platform to manage the distribution and version management of test builds will streamline this process and reduce frustration. Ultimately, an effective process is necessary to scale your user testing practice for the multiple apps and frequent app updates that define a best-in-class mobile strategy.

The best Mobile App Testing Tools: 


It depends on your requirement what kind of tool you are looking for.

Like If you need a detailed feedback, Usertesting is a tool with a unique feature that you can get videos of real people speaking their thoughts as they use your mobile app.

Tunnel Trading: Can This Simple Strategy Earn Profits on Any Future Market?

Tunnel Trading: Can This Simple Strategy Earn Profits on Any Future Market?


Tunnel Trading

 What is  Tunnel trading 


Tunnel trading is a type of algorithmic trading strategy that uses artificial intelligence and machine learning to analyze market data and execute trades. This type of trading aims to identify and exploit market inefficiencies by automating the trade decision-making process based on a set of predefined rules. It can be used to trade a variety of financial instruments, including stocks, currencies, and commodities, and can be applied to different time frames, from short-term scalping to long-term trend following.

There are several types of tunnel trading strategies, including:


Mean Reversion: 

This strategy assumes that financial prices will tend to move towards their average over time and trades are executed when prices deviate from the mean.

Breakout Trading: 

This strategy involves identifying key levels of support and resistance and entering trades when prices break through these levels.

Trend Following:

 This strategy assumes that trends in financial markets persist over time and trades are executed in the direction of the trend.

Statistical Arbitrage:

 This strategy involves taking advantage of temporary price differences between two highly correlated financial instruments.

High-Frequency Trading: 

This strategy involves executing trades at high speeds based on small, short-term price movements.

Swing Trading: 

This strategy involves holding positions for several days to take advantage of intermediate-term price movements.

Position Trading: 

This strategy involves holding positions for an extended period of time to take advantage of long-term price movements.

These are some of the common types of tunnel trading strategies, and the choice of strategy will depend on the individual trader's goals, risk tolerance, and market outlook.

Variation in the Tunnel Trading Strategy

Tunnel Trading

The tunnel trading strategy has its way around the trading market and ensures serious earning for numerous online traders worldwide. You can start winning today by using it. What you must keep in mind is to place online trading orders on both sides of the trading tunnel. The trick here is to constantly analyze the odds and when one side of the tunnel is triggered simply delete the other one. 

This is how online binary traders managed to always be certain not to miss an entry no matter whether it might be a short or long one. The tunnel trading strategy has proven to be highly effective when used properly. It is a simple strategy to consider using but with a high–end possibility of achieving great financial results.

Advantages and Disadvantages of tunnel trading

Tunnel Trading

What you must also know as an online trader basing his activity on the tunnel strategy is that pending orders must always be placed at certain clear distances from the boundaries featured by the tunnel. Why? Because this way you can successfully avoid any false breaks that might mess up your results thus gain a bigger rate of success for your trading activity.

Pros of Tunnel Trading Strategies:

Another great advantage features by tunnel trading is the amazing risk to reward ratio. You have access to a relatively small stop loss order which enables you to reach a great break-out on the market without a lot of effort. This way, the tunnel strategy ensures you access to winning trades that can cover more losses depending on the average R: R. As a result, you can earn more even when you have less successful trades than unsuccessful ones.

Increased Efficiency: Tunnel trading strategies use automated algorithms to analyze market data and execute trades, which can reduce the time and effort required to make trades.

Improved Accuracy: Tunnel trading strategies use complex algorithms and historical market data to make trading decisions, which can lead to improved accuracy compared to manual trading.

Objectivity: Tunnel trading strategies remove the emotional element from trading, as all trades are executed based on predefined rules, rather than on gut instincts.

Ability to Trade 24/7: Tunnel trading strategies can operate continuously, allowing traders to take advantage of market opportunities around the clock.

Cons of Tunnel Trading Strategies:


The greatest disadvanatge in the case of tunnel trading as in the case of any other available strategy is that it is difficult to pinpoint the exact right moment when traders should enter the market. In the end, this is what online trading is really all about: learning to make smart decision based on smart intuition and real facts at the same time. If you make an adequate market research you leave less to chance thus ensuring the success of your online binary trading activity and increase your chances of winning the jackpot at any moment.

High Cost: Tunnel trading strategies often require significant investments in software, data, and infrastructure, which can be cost-prohibitive for many traders.

Over-reliance on Technology: Tunnel trading strategies can be vulnerable to technological failures, such as software bugs or power outages.

Lack of Flexibility: Tunnel trading strategies are based on predefined rules, which can limit their ability to adapt to changing market conditions.

Black Box Concerns: Tunnel trading strategies can be difficult to understand and interpret, leading to concerns about the "black box" nature of the algorithms used.

Market Impact: Tunnel trading strategies can potentially have a significant impact on financial markets, particularly if they are used by large traders with significant trading volumes.

All in all, no online trading strategy is the perfect one for everyone. However, when used properly and at the right moment, the tunnel strategy can bring a lot of profits to all online traders.
