Different Types of Software Testing – Part 2

Different Types of Software Testing – Part 2

Introduction

In the first part, we explained several types of software testing. In this part, we will continue to briefly explain what other types of software testing exist and what they do.

9. Performance testing

As the name suggests, this is a type of software application testing that focuses on testing speed, stability, reliability, and scalability under a specific load.

The goal of this test is to estimate what the output of the application will be. What will be the data transfer speed, network bandwidth usage, how many application users will be able to serve without breaking, how much memory will be used, or how long will be the response time to commands.

10. Regression testing

Regression testing is a type of testing that checks to see if new code changes will break an application and if the application will use too many resources. Regression testing is nothing more than repeating tests that have already been run, either all or specially selected to make sure that the current functionalities are working properly.

11. Sanity testing

This type of testing is usually performed after bug fixes. Checks if all bugs are fixed and if there are any other problems. If the sanity test fails, the build is rejected to save time. Sanity testing is a subset of regression testing.

12. Security testing

Tests for software or application vulnerabilities. The goal of this type of testing is to find potential omissions and weaknesses that could lead to data loss or leaks of sensitive data outside the company.

Security testing not only helps to check system or application vulnerabilities but also helps developers find certain problems and fix them through code.

13. Single user performance testing

Also called client-side performance testing. Evaluates Key Performance Indicators (KPIs) on the client-side such as response time. It takes into account all factors that may affect the end-user experience at all levels including client devices.

14. Smoke testing

This type of testing focuses on the stability of the software application. Checks that all critical program functions are working properly.

Smoke testing is performed post software build, before any functional or regression tests. The goal of smoke testing is to reject software applications with malfunctions so that the QA team would not waste time testing faulty software applications.

15. Stress testing

The operation of the application is tested under conditions that are significantly more difficult compared to the normal operating conditions of the application. The goal of this type of testing is to measure the robustness and error handling capabilities of the software. It is also called endurance testing.

16. Unit testing

This type of testing checks smaller pieces of code to determine if parts of the program are working properly.

Unit tests are usually automated tests written and run by software developers to make sure that a certain part of the application (unit) meets expectations. A unit can be a complete module, but it is usually an individual function or procedure. In object-oriented programming (OOP), the unit is usually the entire interface.

17. White-box testing

It is also called clear box testing, open box testing, transparent box testing, code-based testing, and glass box testing because the code is visible to testers. Internal structure and design are tested to check the flow of input-output data and improve design, security, and usability.

Software testing allows you to identify bugs and errors on time, before the delivery of the software product, which is why it is very important. Properly tested software product ensures reliability, security, and high performance as well as customer satisfaction.

Different Types of Software Testing – Part 1

Different Types of Software Testing – Part 1

Introduction

As applications become more complex, there is a growing need for better software testing. Software testing is a method where it is determined whether the product (software, application) meets all the expected requirements of the client without any errors. The goal of testing is to identify and eliminate bugs in time and correct omissions before the application is officially launched.

Below we will briefly explain the different types of software testing.

1. Accessibility testing

This type of testing is extremely important and is used to test mobile and web applications to determine whether these applications are useful for users without and with disabilities.

Persons with disabilities in this situation are considered to be persons who have:

  • Visual impairment or color blind
  • Hearing damage
  • Cognitive disability
  • Literacy disability
  • Physical disability

2. Acceptance testing

Acceptance testing or as it is also called User Acceptance Testing (UAT) is a type of testing performed by the end-user or client to verify that the application is fully ready and that all requirements are met.

3. Black box testing

Black box or behavioral testing is a type of testing that primarily focuses on application inputs and outputs. Testing is performed without knowledge of internal code implementation. Black box testing refers to any type of software test that tests an application without knowing the internal design, structure, or implementation of the software project.

4. End to end testing

This type of testing tests application workflow from start to finish. The goal is to check if the application works as expected. The real user scenario is simulated and tested by the end-user or client. Because today’s software systems are complex and interconnected with various other subsystems, if one subsystem does not work, the complete system will not work. For this reason, end-to-end testing is performed.

5. Functional testing

This type of testing refers to checking an application, website, or system to see if they are doing what they are supposed to do. QA determines whether a particular piece of software behaves according to predefined requirements. Functional testing uses black-box testing techniques.

6. Interactive testing

Also called manual testing. This type of testing allows testers to create and facilitate manual tests for those who do not use automation and collect external test results.

7. Integration testing

This type of testing ensures that the complete integrated system meets all requirements. It is maintained in an integrated hardware and software environment to ensure that the complete system works properly.

8. Non functional testing

This type of testing refers to checking non-functional aspects, such as performance, usability, and reliability of software applications.

We have divided this post into two parts and in the next post, we will explain what other types of software testing exist. Stay tunned.

Code Review Tools for Developers

Code Review Tools for Developers

Code review is a part of the software development process which involves testing the source code to identify bugs at an early stage. A code review process is typically conducted before merging with the codebase.

In this blog, we’ll explain what code review is and explore popular code review tools that help organizations with the code review process.

What Is the Code Review Process?

The primary goal of the code review process is to assess any new code for bugs, errors, and quality standards set by the organization. An intangible benefit of the code review process is the collective team’s improved coding skills.

If you would like to initiate a code review process in your organization, you should first decide who would review the code. If you belong to a small team, you may assign team leads to review all code. In a larger team size with multiple reviewers, you could enable a process in which every code review is assigned to an experienced developer based on their workload.

The next consideration for you is to decide on timelines, rounds, and minimal requirements for submitting code review requests.

The final consideration is about how feedback should be given in the code review process. Make sure you highlight the positive aspects of the code while suggesting alternatives for drawbacks.

Your feedback should be constructive enough to encourage the developer to understand your perspective and initiate a conversation when necessary.

Why Is Code Review Critical?

Code review is critical for the following reasons:

· Ensure that you have no bugs in code.

· Minimize your chances of having issues.

· Confirm new code adheres to guidelines.

· Increase the efficiency of new code.

How to Perform a Code Review?

There are four ways to conduct code reviews.

1. Over-the-Shoulder Code Reviews

Over-the-shoulder code reviews are done on the developer’s workstation, where an experienced team member walks through the new code, providing suggestions through a conversation. It is the easiest approach to code reviews and does not require a pre-defined structure.

Over-the-shoulder code reviews were traditionally done in person, while distributed teams can follow this method through collaborative tools as well.

2. Email Pass-Around

In this code review process, a developer emails a diff of changes to the whole development team, usually through version control systems that automate notifications. This email initiates a conversation on the changes, where team members may request further changes, point out errors, or ask for clarifications.

3. Pair programming

Pair programming is a continuous code review process. Two developers sit at a workstation, but only one of them actively codes whereas the other provides real-time feedback.

While it may serve as a great tool to inspect new code and train developers, it could potentially prove to be inefficient due to its time-consuming nature. This process locks down the reviewer from doing any other productive work during the period.

4. Tool-Assisted

A tool-assisted code review process involves the use of a specialized tool to facilitate the process of code review. A tool generally helps you with the following tasks:

· Organize and display the updated files in a change.

· Facilitate a conversation between reviewers and developers.

· Assess the efficacy of the code review process with metrics.

How CIOs can achieve work-life balance and avoid burnout

How CIOs can achieve work-life balance and avoid burnout 

CIOs are struggling for work-life balance now more than ever, but it’s harder than it sounds. 

Work-life balance, the loose principle through which you evenly split your time and focus between work and personal activities, benefits individuals and corporations in equal measure. 

A healthy work-life balance can improve health, productivity, job retention and turnover, and in-turn stave off emotional burnout, say experienced CIOs. And yet, attaining a healthy equilibrium between personal life and career work has seemed further out of reach than ever. 

The economic and social fallout from the COVID-19 pandemic has afforded CIOs more opportunity and accountability in the boardroom, and put additional pressure on project delivery teams to expedite multiyear digital transformation programs. Business expectations for IT teams have subsequently blossomed, but this in itself represents something of a double-edged sword. 

Working in isolation while leading teams 

Other CIOs expressed difficulties in working in isolation, pointing to the lack of human contact, the transactional nature of videoconferencing and yet the same pressure to lead, motivate and support teams as well as an ecosystem of partners. For some, fighting the itch to do more has been difficult, even during downtime.  

To achieve work-life balance, set priorities 

Work-life balance can be achieved through delegation and prioritization, as well as setting clear boundaries and taking breaks, CIOs say. But it is also about having a clear idea of what you want to achieve. 

The balance has been about setting an end time in the evening, blocking out time in the day to get away from the desk and making time for informal conversations with team members. 

How to create work-life balance for your team 

These conversations can be part of something bigger. Building trust, transparency and empowerment within teams can help all parties. Somebody goes one step further by suggesting that rewards for a job well done can bring about a healthy work-life balance for all staff. 

NextHealth’s James, who recently became the first male employee at the company to take paid parental leave, says this goes back to the “softer” skills required by CIOs today, such as empathy and flexibility, which can in turn lead to improved talent retention. 

“People are more than just their jobs and the pandemic is forcing many companies to come to grips with that,” James says. “Many workers are pushing for roles that allow them to have greater flexibility in their careers and the companies that embrace that will retain and attract the greatest talent.” 

The work-life balance is ultimately about being smart. “A more balanced life is not just helpful — it’s essential to reaching your full potential. Not only is being happier just as important as being successful, being happier and more balanced actually leads to greater levels of success.”

The Best Soft Skills You Should Have as a Developer

The Best Soft Skills You Should Have as a Developer

Introduction

Usually at a job interview for the position of developer in IT companies HR asks you to present your soft and hard skills. It is clear that hard tech skills are more necessary and have priority because without them the job of a developer cannot be done. However, if you want to work as a developer in the IT sector, the job involves more than just hard tech skills.

What are soft skills and why are they so important?

Soft skills are non-technical skills that help you do your job better. Soft skills are important because they make you a better employee, even if you are a great programmer and have the right hard skills you may not be employed if you do not have the right soft skills.

Imagine a great developer who is too closed and has communication difficulties, it just won’t work. As much as programming was an isolated profession and seemed remote from people, on the other hand, it must be as close to people as possible, because when creating complex applications, communication is crucial, especially communication with the client.

Soft skills are also important because they help developers improve and develop their hard skills. Senior developers will transfer their knowledge to a middle or junior developer only on the condition that they have soft skills. Soft skills affect how well you will fit in with others and since the job is most often done in teams that are constantly changing, having such skills is very important.

Just imagine being a freelancer and doing development, soft skills can help you retain clients. If you have good communication skills you have a better chance of gaining new clients and retaining old ones.

These are some of the most important soft skills when it comes to development:

1. Communication

Technology illustrations by Storyset

Communication is important and is one of the most underrated soft skills for developers, especially if we are talking about written communication. Communication is of great importance because usually the work is done in a team or teams that are on the same project and there must be quality communication and cooperation between different teams or colleagues who are in different positions. Developers usually have a lot of meetings that are also important, especially if the meetings are directly with clients. Written communication is perhaps even more important since, in addition to programming, developers receive and send emails, write documentation for applications and submit various types of reports.

2. Teaching

Online illustrations by Storyset

Teaching is a skill that needs to be learned, it is one thing to tell something and another to transfer knowledge or a complicated area of consciousness to an understandable level. Whether you are a beginner or a developer with years of experience there is certainly something that could be useful to share or something that you know and others do not. Teaching can take many forms, imagine a situation where a developer needs to explain why something the client has imagined cannot be done the way the client asks, you understand the point. Usually, senior developers are in charge of training junior developers through mentoring.

3. Productivity

Work illustrations by Storyset

In a world where we have Twitter, Facebook, Instagram, TikTok, or Reddit, it is difficult to stay focused because these social networks are created to constantly distract. The job of a developer is demanding and can be very exhausting. Developers need some time to start working effectively, we can compare that to warming up before some physical training. Once they start working they are faced with the challenge of maintaining that time of effective work, any minor interruption affects focus and productivity unless it is some planned break with a specific goal. If the developer is tired, under pressure, something else distracts him and because of that he loses focus, he will hardly be productive that day and will most likely not meet even the minimum requirements.

4. Thinking Outside the Box

People illustrations by Storyset

The job of a developer involves many more factors than just programming. If it is an application that represents a project or product for the client, the developer should approach in such a way in terms of helping develop and suggest some ideas if he estimates that they would be useful or that the project is going in the wrong direction.

It is also important that the developer takes care of writing the code so that the next developer can continue the same project if necessary. Usually, developers first write code according to their capabilities but when they gather a lot of experience they want to rewrite the code they used to write before.

It is of great importance that the company recognizes the advantages and disadvantages of its developers. One group of developers may be better at communicating, while another group of developers may be better at some other things. Developers who see the bigger picture and where the company discovers their advantages can contribute a lot to the company. Developers who have a broader picture and who discover the benefits can contribute a lot to the company.

5. Teamwork

People illustrations by Storyset

With more experienced developers, at some point, most come to the same level of programming knowledge and the only thing that remains is the ability to communicate and collaborate on projects. Developers who have problems with the approach, with communication, with teamwork, simply spoil and slow down, both the team and the project. For this reason, social skills such as healthy communication, cooperation, and teamwork are really important. It is these soft skills with developers that are key to achieving a good atmosphere within teams.

6. Problem Solving

People illustrations by Storyset

Programming is not just writing code where we adhere to certain rules, programming is also a way of solving problems that requires a special way of thinking. Before solving the problem, it is necessary to first identify what the problem is. If it is a big problem, it is usually divided into several smaller problems that are solved separately to solve that big problem. To solve a problem, it is necessary to know how to approach that problem, and then devise a strategy on how to reach a solution.

7. Patience and Persistence

Business illustrations by Storyset

In programming, code can rarely work from the first, so a lot of time is spent on debugging. It is often necessary to learn something new along the way and apply it in the current project. All this creates additional effort and stress for the developer, especially if the deadline is approaching. Patience and persistence are great soft skills that make a developer’s job easier.

8. Passion

People illustrations by Storyset

Also, an important soft skill is passion. If a developer has a passion for a certain area and gets a project from that area, he will certainly try and do better in relation to another developer who is not interested in that area at all. On the other hand, passion also pushes the developer to learn more and work on things he likes if he already has to work on projects that are not interesting to him.

Conclusion

After the above items, we can agree that soft skills are very important for a developer. Developers who work on soft skills while learning to program will have an advantage over others when it comes to a job interview or a real job.
