Why Software Testing is very important?

Some people may think coding is the most important phase in the software development life cycle (SDLC), but this is completely a myth that we should tear down. Testing is particularly important because it determines the quality of the software after the Designing and Building phase. Software testing strives for the goal of a free-bug application before it’s delivered to the customers. In the fast-paced and competitive business world, the quality should be the big motto in the IT outsourcing industry.
Savvycom team deeply understands that our clients have invested their money and time into our projects, so our mission is to provide them with stunning high-quality applications. We, therefore, give prominence to implementing software testing procedure. Several following reasons may clearly tell you why software testing plays an important role in our SDLC.

An effective software testing can bring happy clients, customer retention and company reputation.

Software Testing terms could be mixed up

Before going into detail about the software testing procedures, it’s important to make clear some following definitions:

  • Error/Mistake: Errors or mistakes are committed by software developers, which should be software engineers, software programmers, or analysts. In the coding process, a mistyped variable name might lead to an error. When errors arise, they could make the program malfunction.
  • Bug/Defect/Fault: A bug or a defect is a flaw that appears when the programmer makes mistakes while he designs or builds the software or the program. A bug leads to the malfunction of the software.
  • Failure: When a program containing bugs or defects get executed, its system will malfunction, which calls failure.

Save time and money

Important as testing is, this phase is still being underestimated and undervalued, commonly by some of the project owners who don’t know the role of testing teams in the project’s success. Consequently, some businesses cut expenses spending on software testing. In the long term, a program that has not been carefully tested before delivered to the customers could cost them a much larger amount of money than the total they paid for the whole project.
Let’s remember, it would be more cost-effective and time-efficient to make sure things work well in the beginning. The thorough and stringent testing is a budget-wise investment because it can generate great results above expectations.
Software development consists of many phases and the earlier phase bugs are caught in, the lower costs to fix them it costs. Inspecting and curing bugs is similar to detecting and treating cancer. The first stage treatment costs are always much lower than the third stage ones. When a programmer continues coding without testing, his mistakes might betray him during the software development. The further the project’s carried out, the harder it is to correct the mistakes and cure the bugs. This may lead to the misunderstandings your client’s business objectives of the software. Therefore, it’s crucial to get software testing done as soon as possible.

Enhance customer satisfaction and company reputation

Products represent the face of a company. Customers don’t see a company based on the process but on the result. A good product will help you build trust and intrigue the consumers, which, in return, improve your competitive advantage on the market. In contrast, a substandard program will disappoint the customer, demotivate them from buying another product from your company. Therefore, it will likely decrease the retention rate and your company competency towards competitors.
At Savvycom, we have Jio Health, an online healthcare product that collaborated with the Jio tech team. Jio Health is a smart system running on both Ios and Android, which helps Doctors and their Patients connect easier through devices, which also saves a lot of time and gap among patients and doctors. In the beginning, we also had to deal with crashing and bugs, but partly thanks to the meticulous software testing phase which reinforces the quality of the product, we have gained 75000 registrations and 25000 visits, beating a lot of competitors and becoming a breakthrough in the healthcare industry. This cannot be such a boom without the help of our testers, who, with a customer-centric mindset, have spent nights and days to bring the best version to the customers, gaining for us thousands of registration and the trust of the customers.

Ensure security

Security is one of the most sensitive and vulnerable parts of coding. There have been many situations where the user’s personal information has been stolen or being used for shabby purposes by hackers. Especially some information may cause huge damage or danger to users if it gets leaked, for example, banking information, phone number or address. Therefore, many customers nowadays are not willing to fill in the profile sheet lest their information being stolen.
Some might argue that the rate is too small to doubt the security of technological devices or applications. However, chances are it’s not. Even Yahoo, one of the biggest guy on the Internet, had been the victim of a data breach in 2014. According to CSO Online, the attack compromised the real names, email addresses, dates of birth and telephone numbers of 500 million users. In October 2017, Yahoo announced the full face of the scandal to the public, admitting that almost all 3 billion user accounts registering in their system had been compromised. As a result, in the end, they have to sell the company to Verizon, ending an era on which marked their name.

It’s not just a lesson for any businessman before the ultimate power of cyber-attacks, but also a wake-up call to any technology developer. Customers sure have a reason to be afraid of information leaking and other relevant breaches. Therefore, the job of an IT manufacturer is to provide top-notch quality and reliable services so that customers don’t hesitate to give full trust to not only the product but also the company. The moment users refuse to hand in their information is the moment they refuse to trust you, therefore, the moment you lose. Thus, having a strongly protected program is not only safe for your users but also for your business system.
However, truth be told there is no perfectly perfect product that has 0% of defects, we can only minimise the number of errors and maximise the operational productivity and continuously reinforce the security wall. That is to say, one of the most effective ways is to test the product before representing it to the market. By testing, bugs are detected, defects are fixed, security walls will be rebuilt right away if there is any crack in the system. Weak points in the code consequences are found and strengthen, so that not any fault is allowed to be in customers’ sight, therefore, the products on their hand will be of the best condition. Users are no longer need to worry about anything, especially the confidential level of their information stored in the platform.

Differences between QA and QC in Software Testing

In software testing, perhaps two of the most seemingly similar terms that confuse us are quality assurance (QA) and quality control (QC).

Understand the differences between QA and QC in software testing

Yes, the two terms share many similarities and not just the word “quality” (sometimes they are even used interchangeably). But the differences between them are not too difficult to notice.

Software testing, QA definition, QC definition

Differences between QA and QC in Software Testing

So what are the differences between QA and QC in software testing? Savvycom breaks it down in the categories below:

1. By definition

First it is important to note that both QA and QC are part of quality management. The difference in definition, however, lies in the official description of each term by the International Organization for Standardization (ISO):

  • Quality Assurance (QA): Part of quality management. It focuses on providing confidence that quality requirements will be fulfilled.
  • Quality Control (QC): Part of quality management focused on fulfilling quality requirements.

2. By purpose

While the above definitions may sound confusing at first, we can explain in what QA and QC try to achieve to better understand the differences between QA and QC in software testing:

  • QA deals a lot more with the “process”. It ensures quality and develops defect preventionmeasures during the development phase of software. The act of “providing confidence” – as part of QA – often begins very early into software development phase. QA then fulfill software qualities in the future.
  • On the other hand, QC focuses a lot more on the software itself after producing it. This means that QC heavily leans towards defect identification post-production. QC does not focus on prevention at an earlier stage of development. Therefore, QC requires constant inspection and examination of the software. It aims to identify issues to ensure post-production quality before releasing to customers.

We can also draw from the above understanding: QA is a proactive process, in which it anticipates defects before they occur; QC is a reactive process which respond to defects only after completion of software.

3. By capabilities

Another way to understand the differences between QA and QC in software testing is looking at what they do.

  • QA is pretty much a prevention system that predicts everything that can possibly go wrong with software (bugs, malwares, etc.) before and during development and sets up criteria for the software to determine its status before letting it reach the other stages of the development phase.
  • QC is similar to a policeman; a detection system that searches for software flaws after successful development, primarily by the means of testing it to ensure that it meets the criteria before reaching the hands of customers.

4. By responsibility

The group of people who carry out assurance and control activities are also one of the key differences between QA and QC in software testing. Most of the time, QA and QC have specific people assigned to them as following:

  • QA is normally conducted by project managers, the software development team, customers themselves, and sometimes by third-party examiners. Or simply put, QA involves the efforts of everyone assigned to developing the software.
  • QC is mostly executed by a special team of people whose primary duty is to test the finished software. The QC department holds critical importance in that they test the software to identify and correct defects, in the process helping to polish and perfect it to deliver a satisfying customer experience later on, as it is very important to not let customers suffer from unchecked bugs after launching the software.

Regardless of the above differences between QA and QC in software testing, it is suffice to say that they hold equal importance to quality management of software. A QA/QC program usually serves as a Quality Management System (QMS), which software development companies utilize to save costs, time, and mitigate risks that may occur with their products.

5. Benefits of QA/QC

QA/QC, once performed together in software development, brings out many benefits for the development company, including:

  • Satisfying clients with the final results of software, which increases a company’s reputation on the market. This also means the company will potentially have long-term strategic partners.
  • Removing the excess time and costs for continually checking and fixing the software to deliver solutions. A carefully planned QA/QC strategy means that companies can always be confident of quality, avoiding unnecessary defects that occur when rushing the development to meet deadlines without proper evaluation.
  • Monetary rewards for the company, since QA/QC helps to deliver the best quality of software, it also means customers are more likely to engage in future projects and refer to new potential partners, especially in the IT outsourcing world.
  • The adoption of strict QA/QC strategies and plans when developing software gives a company’s software development team a sense of professionalism, perfectionism and more motivations to work more efficiently.
