Besides, an insecure mobile app can be a loophole for cyber hackers that intrude into a user's system and hack a smartphone overall.

Almost all apps refer to servers that are vulnerable to the same types of cyberattacks as desktop and web apps.

However, mobile apps have better security measures and a smaller attack surface.

But there are principal security issues we should pay attention to: Local data storage.

Improper usage of APIs system by an app can cause data breaches and other security issues.

Smartphones connect with various networks regularly.

Agile methods and CI/CD added a tendency to fast and frequent delivery of a code.

One of the ways to improve the development process is software testing.The robust testing strategy facilitates an arduous development process and increases the chances to stand out among thousands of applications in stores.

The strategy depends on the type, size, and goals of a project.Functional testingFunctional testing ensures that all main app functions and features are workable and give correct responses.

If it's a social app, the main functions will be adding photos, sending messages, sharing posts, etc.

For booking apps, it is searching tickets and places, ordering, safe payment methods.

Besides core features, there are crucial test cases to consider: app launches and works correctly every timefields and buttons respond correctly app behavior when something interrupts its work (turning off, incoming call other issues) users get notifications and alerts about incorrect app workafter system crashes and errors app can resume at the last operation Usability testingStudies show that 79% of users reject using a mobile app with bad usability and pick an app with a better user experience.

Besides the various benefits of automation testing, engineers can't automate all test cases in a project.

Automation is a tool that can improve performance and speed up the development process, but not a panacea.

Enginers should be very selective when deciding what to automate.

Thoughtless usage of automation brings more material and physical expenses.

Some examples when automation testing undesirable:when we pay attention to user experience and usability one-time run testsexploratory testing when engineers check the system on the fly to discover and learn the system before testingtests without predictive results.

An automation test must have definite results to be successful.Read more in the article.

Many product owners invest money in app development to increase profit and get more clients.

Nowadays, it's a great idea because most people use smartphones almost for everything - making photos, ordering, communicating, sharing files, etc.

According to Statista, half of the worldwide web traffic from mobile devices.

But app development is a complex process that requires a lot of effort and expense.

Eventually, there aren't guarantees that an application will become popular and bring high profits to its owner.

The market is full of various types of apps, and competition is very high.

In the last few years, Agile methodology is getting more popular among development companies.

Development teams are replacing the classic waterfall framework on Agile as it is more flexible and focused on high-quality results.

According to StackOverflow Insights 2018, 85,4% of 101,5 of international companies use Agile methodology.

Agile facilitates faster product delivery and can be implemented in any activity during the development process.

Thus software testing is provided during the whole long development process and is a simultaneous and continuous activity with the writing of code.

Such an approach allows teams to get quick feedback and tightly cooperates with the development team that increases the quality of workflow.

A web app is a great tool for interactions between clients and a company product.

But because web apps store and process a lot of sensitive and private clients' information, they frequently occur under scammers' spotlight.

SQL injectionSQL is a query language that can be used for access, changing, and deleting data in databases.

According to Edgescan 2020 Vulnerability Stats Report, 42% of web app vulnerabilities were caused by SQL injections.

It is one of the most popular cyberattacks as it is easy enough to perform.

The main danger is that a large part of the web is built on SQL.

Repetitive and big data test cases are the best candidates for automation.

But automation is expensive and unnecessary for small and short-term projects with small codebases.

Sometimes automation regression testing is impossible due to the low ROI of it.

In this case, manual testing is the best choice for regression testing.

So the first lesson of automation regression testing is automation isn't a panacea for regression.

Automation regression testing should be based on manual test cases that repeatedly reveal failures.Automation testing is extremely useful for big and mid-sized projects with increasing codebases.

Combining several types of software testing enhances results accuracy and increases performance.

Stress testing allows testers to create difficult conditions that can happen during real use, determine bottlenecks, and prevent performance issues.

It's better to conduct stress testing on real devices but not on emulators.

Another combination is functional and load type of testings, which is similar to the previous one.

With this combination, you can observe the behavior of app functions under high web traffic.

Manual testing helps to identify bugs from users' perspectives and improve user experience.

 In Agile development, companies deploy code fast and often.

However, this approach may affect the quality of a product as sometimes companies sacrifice quality due to lack of time.

For many years a qa company measures software quality.

Their goal is to estimate the product for compliance with quality requirements.It helps release the product at a high-level quality, stand out among competitors and increase company revenue.However, many companies failed to achieve software testing quality metrics.

It happens due to poorly developed metrics that can't prevent risks.What is software quality?Software quality focuses and provides meeting quality standards and requirements.

Software quality metrics are a reliable tool to measure how close to established requirements you are or prove a theory.

Let's consider the main kind of testing that you need for seamless e-commerce website work.Performance testing.

There is research that shows that high load site speed leads to a higher conversion rate.

Slow load speed can be caused by many factors as the amount of traffic or quality of hosting.

Performance testing services identify a set of parameters as speed, scalability, stability, resource usage under the particular load.

With these standards, owners can be sure that their website can cope with a high amount of traffic, expands in the long run easily, gets better optimization, and so on.

But the truth is that 58% of businesses with less than 1000 employees experienced cyberattacks.

To avoid risks, let's consider moments to pay attention to before hiring a QA outsourcing team(https://u-tor.com/services/qa-outsourcing).

Experience and a full scope of services Even if you hire a QA team for one kind of testing, bear in mind that you may need a broader range of services later.

Ensure that the vendor is able to cover a wide scope of testing and have sufficient numbers of testers to provide them.

Competent teams have their techniques, approaches, and frameworks in software testing.

You can ask a vendor about methods that a team has used and is implemented in a testing process.

Level of trust Reliable and professional teams arrange a full pack of documentation and can provide it to you at any moment of a workflow.

A working principle of black-box testing is similar to its name.

Testers are interested in data input and output, excluding internal program structure.

For engineers, a program code, design, and internal structures are a black box in which testing is not conducted.

Also, black-box testing covers performance and usability issues, functionality from the user's perspective, the system's interaction with the inputs, etc.

Among other advantages are independence between developers and testers, test cases can be designed as soon as software functional specifications are complete, acceptance for a large system.

On the other hand, a beginner's lack of technical knowledge can lead to an omission of possible test cases to be tested.

The market offers a huge number of QA teams for outsourcing.

Therefore, to facilitate the search for a team, answer the questions below.What type of outsourcing do you prefer?QA testing services can be onshore and offshore.

Today, there are thousands of companies on the market that offer both types of services.

But there is one significant difference between domestic and foreign companies: the services of offshore companies are cheaper.Offshore companies’ benefits:Highly qualified staff and high-quality work at a low priceConstant support of the projectMinuses:Different time zones, which can be inconvenient for communication and discussion of the projectDifferences in the judicial and legal systems, which may complicate the process of resolving troublesIf it is not possible to transfer the project to an offshore company, contact an onshore company.

The services of such a company will cost much more, but the risk of problems associated with resolving troubles is reduced since this company is nearby.2.

What are your QA needs and priorities?If you don’t know anything about software testing, it will be difficult for you to prioritize and your QA needs.

Manual testing is performed by a testing engineer.

The tester manually prepares data sets, conducts software testing, identifies bugs, and writes reports without using any tools and scripts.

Manual testing may not be accurate due to human factors, take more time and resources, but some tests as usability testing you can't conduct automatically.

Automated testing requires scripts and code for automation to verify test cases.

Testing engineers write code and based on this code run automation testing.

This type of testing enables you to simulate complex scenarios and increase the productivity of your team.

Automation testing is a popular and fast-growing direction in testing.

It has many miss issues and myths and misinterpretations.For robust work, automation testing services should know what test cases to automate.Which test cases can be automated?

When you decide to start test automation in your project, you may ask: " What I can automate, and what can't?"

It's a good question because from one side test automation increases test quality, reduces time spent on tests, and saves resources.

Another side of test automation is too expensive to apply it to all cases, and sometimes there is no need to do it.

There's one good advice — use test automation where humans won't cope or one mistake can lead to fatal consequences.
