Mobile App Performance Testing - Challenges

Software testing is of two categories: black-box testing- in which the internal design of the application needs not to be known to the tester; and white box testing- where the tester should have prior knowledge about the implementation of the program or software to be tested.

A performance test is a non-functional testing method that checks how well an application will run when subjected to a high degree of load. Performance parameters such as stability, speed, and scalability are estimated throughout the testing. The precise performance testing tools may carry out a wide range of trials on diverse systems.

In this article, we have demonstrated the various types of performance tools, why you require performance testing, the point to reckon, the challenges of performance testing, and useful performance testing tools available with their crucial features and protocols.

Performance Testing

Performance testing is a non-functional software testing method that examines how smoothly an application’s stability, speed, scalability, and responsiveness cling up under the workload threshold. It is correspondingly known as load testing.

Although it is a significant stage in assuring software quality, performance testing is treated as an afterthought and only performed after functional testing. And in most specimens, after the program is set to be released.

Performance testing analyzes application output, reprocessing speed, data transfer rapidity, network bandwidth consumption, paramount concurrent users, memory use, workload effectiveness, and command response times. It is a subset of performance engineering and is occasionally pertained to as perf testing.

Need for Performance Testing

Performance testing is run to offer facts to stakeholders about their app’s performance, scalability and stability. Performance testing, additionally, reveals what has to be addressed before a product is released to the market. Without performance testing, the software is likely to have challenges like slowness when several people are using it concurrently, inconsistencies across various operating systems, and skint usability.

Under prophesied workloads, performance testing will demonstrate whether their software satisfies speed, scalability, and stability criteria under prognosticate workloads. Applications that are released to the market with poor performance yardsticks due to inadequate or lacking performance testing are probable to earn a negative mark and fail to fulfil sales targets of the software.

Types of Performance Testing

  • Load testing: In this type of testing, the capacity of an operation to handle anticipated user loads are evaluated. Before the software program goes online, the aim is to identify performance backups.
  • Stress testing: In this type of testing, an application is put through its paces to analyze how it reacts to extravagant traffic or data processing. The aim is to determine where the breaking point of the app is.
  • Endurance testing: This type of testing ensures that the software application can resist the presaged load for a length of time.
  • Spike testing: It examines the response of an application to large harpoons in a user-generated workload.
  • Volume testing: Here, the data is entered into a database, and the general gist of the software is covered. The aim is to check the performance of a software operation with varied sizes of the database.
  • Scalability testing: The method investigates how readily a software scales up to nurture an increased user burden.

Points to consider for Mobile Performance Testing

Performance is a facet to hold the user. However, users will not use them if the application is lagging. Some of the points to consider for mobile app performance testing are as follows:

  • The launch time of a mobile application should be as low as possible.
  • Time to render the screen should be reduced.
  • Mobile applications should not downshift in for resource-heavy exertion such as downloading and uploading.

Challenges of Performance Testing

The critical challenges which are faced by the testers while carrying out mobile app performance testing involve:

  • Organizing diverse mobile platforms and their operating systems
  • Simulating connectivity such as Edge, 4G, 5G or Wi-Fi
  • Limitations of mobiles such as battery and resources consumption
  • Mobile phone usability
  • The varied sizes of mobile devices to run the identical app

Troubleshooting Mobile Applications Performance

After catching on to the challenges of performance testing for mobile apps, testers should trace and rectify faults.

Problem 1: Lag or languid response of the Mobile App

  • The reason for this holdup may be the RAM, cache.
  • You need to kill unwarranted courses or clear the cache. Troubleshooting the connectivity effect may unravel some of the problems that are creating lags

Problem 2: App restarting, freezing, locking up or unresponsiveness.

The following can fix the issue:

  • Optimizing the application codes
  • Software must be renovated and updated.
  • Automatic restores
  • Managing RAM or ROM (in some cases) while employing external devices
  • Wiping the cache partitioning
  • Substantiating the app function with different third-party apps and APIs
  • Mapping the mobile application conforming to the device

Some Mobile App Testing Tools

Mobile performance testing tools vary according to the devices or mobile Operating systems. Some familiar mobile app performance testing tools are

Robotium (Android)

This app functions just like Selenium for Mobile Apps. The tester can record and play in different ways needed to perform testing.

Monkey Runner (Android)

Monkey Runner can perform tests on real devices interlinked to a PC or emulators. The implement has an API, which allows controlling a smartphone, a tablet or an emulator from outside of Android code.

Automator (Mac or iOS)

Automator was developed by Apple for OS X. The app implements drag-and-drop workflows for automating reiterative tasks into arrays for quicker revision. This saves time and trouble over human intervention to manually alter each file mutually.

Conclusion

It is indispensable to carry out performance testing in software engineering before releasing any application on the market. Performance testing ensures consumer pleasure and preserves the investment of an investor. Additionally, performance testing enhances the sale of the application or software with increased customer loyalty, happiness and retention.

Deep Learning

If you are a fan of science fiction movies, then you must already be familiar with humanoids. It is fascinating to see the battle between humans and machines and take your imaginations to the world where humans and robots coexist. Well, today you can watch humanoids for real, thanks to artificial intelligence. The best example of a device powered by Artificial Intelligence or AI is voice assistants like Siri, Alexa, or Cortona. The device can hear what humans speak, perform the desired task, and respond back in the natural language used by humans.

When you start exploring artificial intelligence, you will particularly come across its subfields machine learning and deep learning. The reason why deep learning has gained so much traction is that it powers many present-day applications like fraud detection, visual recognition, driverless cars, computer vision, natural language processing, and emotional intelligence. Deep learning is something that works based on the structure and function of the human brain. Simulating the biological neural network, deep learning involves the use of artificial neural networks. Such networks basically refer to a series of algorithms that finds hidden relationships in a given set of data.

This article gives you more information on the types of deep learning networks and why you should enroll in a free deep learning course to know more about them.

Exploring the Types of Deep Learning Networks

Artificial Neural Networks or ANN is a biologically inspired computational network that facilitates the recognition of patterns and solutions to common problems in the field of deep learning. Here are some of the common deep learning networks or types of ANNs.

Multi-layer Perceptron

It is one of the basic ANNs you will come across. Multi-layer perceptron is a feed-forward network made up of input layer, hidden layers, and output layer. The input layer receives the signal, the hidden layer acts as a computational engine, and the output layer finally performs the desired action like prediction or classification. Training such a network involves adjusting the parameters like weights and bias so as to minimize the error. MLPs are used for applications like recognition, approximation, pattern classification, and prediction.

Convolutional Neural Network

Convolutional Neural Network or CNN is an algorithm that takes an image as input, assigns parameters to several aspects in the image, and allows the network to differentiate one from the other. Utilized mostly for classification and computer vision applications, CNNs or ConvNets offer superior performance when the inputs are in the form of image, audio, or speech. In contrast to MLP, CNNs have three major layers, namely convolutional layer, pooling layer, and fully-connected layer. A linear operation where we multiply a set of weights with the input is called convolution.

Recurrent Neural Network

In common feed-forward neural networks, the inputs given are independent of each other. A recurrent Neural Network or RNN comes into the picture when we have inputs that involve sequences. It is used when a given data point in a sequence depends upon the previous data point. The neural network is modified accordingly to incorporate the dependencies between the data points in the sequence. In other words, RNNs have ‘memory’ as they temporarily store information from previous inputs to influence the present input and output. Voice assistants like Alexa and Siri use RNNs to store a sequence of words spoken by a human and perform speech recognition.

Radial Basis Function Networks

One of the most useful neural networks, Radial Basis Function or RBF is applicable for function approximation problems. Universal approximation and quick learning speed are the two features that make RBFN unique from other neural networks. This is also a feed-forward network consisting of three layers – input, hidden, and output layer. The activation function used in the hidden layer of RBFN is usually a Gaussian Function. It has been observed that RBF networks typically require less time to reach the end of the training in comparison to multi-layer perceptrons. RBF networks are being used in a number of applications like anomaly detection in data, stock price prediction, fraud detection in financial transactions, and others involving interpolation, classification, and time series prediction.

Modular Neural Network

In simple terms, different models of neural networks combined into a single system make a modular neural network. Every single NN is made into a module that can be intermixed with modules of other types in the system. These neural networks are used for strongly separated architecture, and each of the networks works independently on its own domain. This network is known for its efficiency, independent training, and robustness. The target recognition, high-level input data compression, and character recognition with adaptive MNN are some of the popular applications of this neural network.

In Conclusion

The neural network is an interesting topic to study when you start with deep learning and AI. If you are serious about a career in this domain, then enroll in a free deep learning course online. You would be better prepared to gain the right skills and become job-ready when you learn from industry experts and cover all the topics step-by-step through a deep learning course. So, enroll now and reap the benefits associated with it.

The Responsibilities of a Managed Service Provider

Published

Managed Service Provider

No business can afford to have their IT systems go down, but many businesses can’t afford the time or the money to dedicate a full IT team, or even a single person, to look after their networks, upgrade software, look after cyber security, and do all the other tasks needed to keep things up and running smoothly.

You’re either left with crossing your fingers and hoping nothing goes wrong or getting the most IT savvy person in your business to do their best and look after things, taking time away from what they should be doing.

Neither is an appealing option if you don’t have the budget to hire a professional, but there is an alternative.

What is a managed service provider (MSP)?

A managed service provider is an outside service provider that offers IT services, such as network management, leased lines, VoIP, cyber security, and more, giving businesses the IT support they need, without having to pay one or more full-time salaries.

Your MSP might source and install hardware on your behalf, help you migrate to the Cloud, or install your new VoIP phone system with a leased line to give you fast and reliable, no contention ratio broadband.

You might hire them to simply cover evenings and weekends or holiday cover when your own IT people aren’t available, or your MSP may be your entire IT team.

Security and safeguarding

From the UK government’s Cyber Security Breaches Survey 2021, “Four in ten businesses (39%) and a quarter of charities (26%) report having cyber security breaches or attacks in the last 12 months.” https://www.gov.uk/government/statistics/cyber-security-breaches-survey-2021/cyber-security-breaches-survey-2021

Added to what’s become a regular onslaught of cyber-attacks against businesses is the increase in remote working due to the pandemic. While that’s a good thing, in that it brings added flexibility for employees and employers alike, it does increase the demand on IT departments and increase the risks of a cyber-attack. Home networks and laptops aren’t as secure as a proper in-house business IT system, or as easily managed.

With so much happening on the cyber security side of things, it’s unreasonable to expect any business to manage their systems without IT support of some sort, and that’s where an MSP can be an excellent solution.

Your MSP will have the resources to constantly monitor and upgrade your systems, check for malware and viruses, and provide the secure, regular backups you need if something goes wrong and you need a quick restore to get your business back up and running again quickly.

Cost-effective IT support and services

When you hire a full-time IT person to work in your business, you’re not only paying a salary, but you also have to pay National Insurance, provide a pension, and maternity/paternity benefits, among other things. You need to spend time on recruiting the right person and on training them, and all of these things cost money and time.

Then they want holidays and evenings and weekends off and your system isn’t covered when they aren’t there.

With an MSP, on the other hand, you only pay for what you use. You’ll have a Service Level Agreement (SLA) that sets out their responsibilities and what you can expect from them. You don’t need to pay for a full-time salary plus benefits, and you can get cover for outside hours, holidays, and sickness whenever you need to.

That leaves your systems covered and protected by IT professionals for far less than you’d pay for a full-time employee.

Identify ways to improve processes

A professional MSP will have different employees who are experts in their field so you don’t have to be.

They’ll be able to look at your current systems and recommend upgrades and improvements that make a big difference to how efficiently your network, and therefore your business, runs.

With the right MSP, you can also rely on them to work with you to improve your IT processes. You’ll be able to rely on someone who knows exactly how to get the most out of your systems and processes, and what to put in place to improve them.

Instead of ad hoc processes that don’t refer to each other or create a complete set of smooth-running processes, you can have full IT systems processes that cover everything from how to update your software, when it should be done and who by, to what happens if your business is hacked. With a full suite of procedures and processes set up, there’s no need to scramble and try to figure out what to do. You already know. All you have to do is look up the right process and follow it. Job done.

That’s the difference a good MSP can make to your business.
