Businesses around the world succeed based on the quality of services they provide. The easier it is for customers to navigate and use the developed products & solutions, the happier they are with you as a service provider. Quality assurance plays a major role in making your products bug-free and intuitive. This means, once you deliver a pristine product to your customers, there would be a lesser number of do-overs or revisions, hence, saving time and resources for your business. 

Let me share an example of how a bad-quality product affects business, as well as, human lives:

NASA’s shuttle, Challenger, exploded just after minutes of taking off, resulting in the death of seven astronauts who were on board that space shuttle. The mechanical cause of this failure was the Solid Rocket Boosters ’O’ rings. An extensive report by Jeff Forest, from Metropolitan State College, points to a flawed Group Decision Support System which misinterpreted the risks and failed to communicate concerns surrounding Quality Assurance. The whole project was shut down at the time.

In light of this incident, we can say that Quality Assurance of hardware, software, or any product of any kind, plays a very important role in business growth. Lack of it causes a waste of effort, time, and money. Before knowing how Quality Assurance is profitable for any business, let’s first have a little background of the term ‘Quality Assurance Testing’, and explore the whats, whys, and hows of it.

What is quality assurance testing?

Quality Assurance is about making sure that your software conforms to the requirements set by the client, and it works without any defects and failures. QAs/testers should run the program by keeping in mind every possible scenario to detect any defects, ensuring a successful run of the program. Now, what do I mean when I say defect-free software? For that, we have to define the term “defect”.

Defect/Bug: A defect is an anomaly in the product, something that deviates from the expected behavior. For example, you want to log in to the website on your browser. The login button is supposed to direct you to the login page but instead, it takes you to the help page. This unexpected behavior is called a defect or a bug as it is not conforming to the requirement.

What does a tester do and why do you need them?

A tester is someone who assures the quality of the product by running the program for every possible scenario while testing.

Basically, this is what a QA tester does:

software quality assurance life cycle

To ensure the quality of software under development, there is a series of processes followed to deliver a product — It’s called Software Testing Life Cycle (STLC).

STLC includes the following stages:

  1. Gathering requirements
    Requirement gathering is the first and foremost step in the STLC. In large-scale projects, it is vital for the project team, i.e., project managers, developers, designers, and QAs, to know exactly what the client is expecting from them. The bigger the project, the more extensive the requirements. Requirements are gathered from the clients and their stakeholders in the form of a written document or prototype, generally. 

    Time is money. With poor quality requirements, projects either fail, are completed late, or go over-budget. This is a reason enough for any business to pull off their projects from a software company, hence costing you money.
  2. Test planning
    Test plans are written to define the testing strategy. Test planning is done by the Test Manager or the Test Lead. It tells us how and when the testing activities will be carried out. It is done to plan the time, effort, and cost consumption of testing for the entire project.

    Test planning not only gives us a strategy for testing activities but also helps us estimate the budget of the project. Poor test planning leads to failure in reaching the milestones. In a fixed-cost project, it can cost you your time, effort, and money.
  3. Test case development
    After test planning, test case development is the next step. In this phase, the testers create test cases that cover every possible scenario in a very detailed manner. Test cases are developed to ensure even the edge cases won’t cause problems in the workings of the software.

    Test case development, if done right, can save you money, because, in this particular step, you are making sure the software does not break at any step. Hence, this assures that no further effort of the developers is required and the product is credible. A credible delivery brings in business, which brings in money.
  4. Test environment setup
    Setting up the test environment is a vital part of the STLC. Basically, the test environment decides the conditions on which the software is tested. This is an independent activity and can be started parallel to the test case development. In the process of setting up the testing environment, the test team is not involved in it. Based on the company’s policy, it could be that a developer or customer creates the testing environment.
  5. Test execution
    In this phase, the testing team starts executing all the test cases in a particular test environment that was set up by the development team or the customers. Each test case is marked ‘passed’ or ‘failed’, depending on its failure or success. Some test cases can be blocked for execution due to some system constraints, and hence, marked ‘blocked’. If the test case is blocked, the relevant bug is reported.
  6. Bug reporting
    When a test case fails, the reason is that it is not working as expected. Thus, a bug/defect/issue is logged using a preferred tool and planned in the test plan.

After going through all the phases of the STLC, the final test execution summary report with exit criteria is prepared to show the stakeholders whether the software is ready to be launched or not. So, testing the software by following the STLC will save you money as it takes care of your estimates of the effort, time and money you are putting into it.

When to start testing?

It is always preferred to start testing alongside development. An early start to testing reduces the cost and time to rework and produce error-free software that is delivered to the client. However, in the SDLC, testing can be started from the requirements gathering phase and continued until the deployment of the software. 

SDLC and STLC go side by side in a project. The diagram below can better explain how they are being done simultaneously while the software is being developed.

What impact does SQA have on your business?

In Software Quality Assurance, a defect is the stitch which resolved on time saves you time, money and effort. Allocating some of your resources to QA Testing can actually reduce your total development costs while also stimulating more growth.

SQA brings the following benefits to the business:

  1. Quality product
    Quality is everything for a customer. It is achieved through proper testing of a product. If you want your product to survive in the industry, that will be possible when it has gone through testing.
  2. Reduce developmental cost
    Finding defects in the earlier stages of development can save you a lot of effort. In that way, you do not continue building upon faulty code. A faulty piece of code can be longer than the one written upon fixing a defect. Reducing lines of code reduces the developmental cost.
  3. Save time & cost in fixed budget projects
    In a fixed cost project, finding bugs and fixing them in the early stage of the project proves to be beneficial because when the deadline is here, there is no room for defects and efforts to be made. There will be a spill-over.
  4. Customer satisfaction
    A happy customer is not a myth when a quality product is delivered. It helps you gain a larger number of customers. If you are a product-based company, when you deliver the software and customers use it, it will bring more customers and more customers to bring more money and business. When clients receive defect-free software, there will be positive feedback and positive feedback will bring a large number of projects to the business.
  5. Less promotion, more recommendations
    A customer would love to use a good quality product. A product won’t need much promotion if a happy customer starts recommending it. So, the cost of marketing is saved as word of mouth will be the source of it.
  6. Profitable
    Surely, the idea of hiring QAs does not seem profitable. It makes you think that you are spending more money. However, testing a product before selling it in the market will only increase the number of buyers. Nothing throws a software company out of business than an unsatisfied customer who regrets buying a product that does not work. It’s a long-term gain.
  7. Client confidence
    Retaining your client-base so they bring in more projects is only achieved if the very first software you deliver is defect-free. The quality of the product leaves your client satisfied and they will always confide in your ability to deliver a quality product every time.
  8. Saves corporate-level data hazards
    If you are deploying your software in an enterprise-level company that involves high-level security of data, without proper QA of the software, it may result in a defect that results in leakage of sensitive data. It is a hazard that’s difficult to overcome on this level of deployment. All of this could be avoided by testing the software beforehand.

All in all, the benefits of quality assurance are significant. Your software and your services gain customers, recognition and market value.

Debunking the myths

Over time you might have heard some myths about Quality Assurance and how it is not necessary or how it adds to the cost and time of the project. However, as of now, these myths have no meaning because almost every software development company hires not only developers but QAs for the projects too. QA reduces costs instead of adding to them. It is surveyed that a product delivered without testing costs a business more than hiring a team for it. A non-tested product is usually buggy, and may not cover the initially set requirements or direction.

Another myth is that QA is only done by the Testers. This is a big no. It is not only the responsibility of the QA but the developer as well. Developers have to give a working code to QA for testing and it cannot happen unless the developer tests it first.

Quality assurance is vital throughout a project’s life cycle. It always adds value to your business and saves you money by making sure that after a product is delivered, it is defect-free and doesn’t cause any problems to the client. Quality assurance and quality control, both fall under quality management and are essential to the STLC process. Testing and development should be done in parallel to avoid the defects found there. Quality delivery builds consumer-client trust, enhances customer satisfaction, and reduces developmental costs, which, in turn, adds money to your business.

After weeks of hard work, countless meetings, and a successful project delivery later, we’ve decided to pull back the curtains on exactly what it takes to assure the quality of a high-availability healthcare app.

Back in April 2020, when the first wave of the novel Coronavirus was at its peak, VentureDive reached out to the Government of Pakistan to help the country combat the virus through technology. As part of the ‘Digital Pakistan’ initiative, spearheaded by Tania Aidrus, an ex-Google executive, we collaborated with her team to build and launch the COVID-19 telehealth portal. It is a website specially designed to combat the crisis of the pandemic. It allows Pakistani doctors and all healthcare professionals to register on it and volunteer to remotely help the patients who might have COVID-19 symptoms.

“VentureDive team, I cannot thank you enough on behalf of the entire team for leaning in to help! There has been SO much interest in the platform and what’s interesting is how much interest we are seeing in other verticals. For example, today we had a call with the Law Ministry who are very eager to do something similar to sign up volunteer lawyers to provide free guidance to victims of domestic abuse. I hope this is just the beginning of our working relationship – excited to have started off on doing something that I hope can help thousands of Pakistanis during this time.” — Chief Digital Officer, Digital Pakistan

Healthcare is a very sensitive subject and it was a technology to be used by millions of people across Pakistan. Therefore, it demanded the highest quality, with zero downtime, zero bugs, and intuitive user journeys.  In this blog, we’ve highlighted our experience of testing a portal that was to be used by healthcare professionals to reach out to patients via our technology.

What follows is a tale that tells the challenges we faced during the three-week-long project, and how we resolved them to successfully deliver a web and a mobile application.

The functional, security & scalability challenges of testing the telehealth portal

Before the project kicked off, the quality assurance team at VentureDive gathered the application requirements and shared them with the experts dedicated to working on this. A thorough documentation and sample mockups helped the QA team to begin working on the test plan, test design, and test cases during the development phase. We conducted daily stand-ups so the development & testing teams could stay synced and brainstorm on maneuvering through this project smoothly and in time.  We faced six major challenges during our course:

Time management

The main challenge was racing against time to meet the client’s expectations while ensuring the security of the sensitive healthcare data, and zero glitches within the app. This meant that the QA team had to keep track of every requirement and reporting templates for testing updates that helped the development team fix defects and bugs timely, prior to delivering any milestone to the client.

3rd party integrations

The application was to be integrated with third-party software such as WhatsApp chatbot for doctor-patient communication & telecom operators to enable anonymous calling mechanism and receiving SMS OTP. These were essential for fetching data from official sources and making sure both our applications remained in sync with the whole system we were creating.

Mobile responsiveness

The telehealth portal was supposed to be a hybrid mobile application, which meant that the testing team had to test it across various mobile devices and operating systems to make sure that it was responsive and compatible.


Cyber attacks and threats are a real-world problem today with thousands of networks and websites being compromised each day. To help identify, classify, and address security risks, we performed vulnerability assessment and penetration testing activity including server VA, API penetration testing, and web application penetration testing to identify possible routes an attacker could use to break the system.

System performance

Monitoring the performance of the application was an integral part of building the portal, since we anticipated a large number of users, including doctors and patients. The QA team planned to automate the scripts on JMeter to determine how the system performs in terms of responsiveness and stability under heavy load and a huge volume of data.


A big challenge for the QA team was to keep the testing practices as standardized as possible even with a short time to spare. VentureDive believes in maintaining the quality of the deliverables as our utmost priority, regardless of the length, complexity, or intent of the project.

Adopting a smart testing strategy for successful project delivery

The process of Alpha testing was done remotely. The QA team collaborated and focused all their efforts towards detect any major defects in data security. We carried out usability, performance and security testing for private and sensitive information in a healthcare setup.

It was pertinent for the QA team to also analyze business criticality, plan around testing efforts in minimum time, make the application usable for thousands of users and ensure that testing was compliant with the Open Web Application Security Project (OWASP) standards.

The test strategy called for having separate environments for development, staging, and production. We performed the following steps in the given order:

Functional testing

Keeping in mind the criticality & nature of health-related projects, requirements had to be precise and the validation had to be perfect. We performed static analysis on requirements followed by actual test execution to meet the requirements and clients’ expectations. Data flow integrity and business rules were repeatedly tested via automated suites in our regression cycles


  • Postman for API automation & integration testing
  • TestRail for test cases and test cycle reporting
  • PostgreSQL for data validations

Cross browser testing

Browser compatibility was mainly focused on Google Chrome version 80+ on windows. Extended smoke and regression cycle was performed on Firefox and Safari for Windows and Mac respectively.

Understanding the market trends of portable devices, we analyzed the data of the target audience and performed UI/UX testing on mobile & other portable devices. The application was tested on 6 different Android and iOS devices with different screen sizes and resolutions having different OS versions.

Security testing

Thorough security testing was performed on infrastructure, API, and application level, keeping the top 10 OWASP standards in mind. 


  • Burpsuite
  • ZAP 
  • KALI Linux operating system

The QA team identified the following vulnerabilities during the security testing activity:

  • Broken access control
  • Broken session management
  • Disclosure of internal directories
  • Unrestricted file upload
  • Missing server validation
  • Sensitive data exposure
  • Brute Force 
  • No rate limit
  • WAF & ACL implementation

Our goal was to immediately address these issues and recommend further best practices that should be followed as pre-emptive measures against any potential cyber-attacks.

Performance testing

The system undergoing the test was required to have a load-balanced infrastructure supporting thousands of interactions between the patients and the doctors. The flow includes the signup process including uploading of images, populating, and fetching patient data lists and assignments of users one to one. 


  • Jmeter
  • Blazemeter

We analysed all the results, and generated an extensive report using SmartMeter, which was later shared with the stakeholders. The primary issues identified were load balancing, CPU utilisation, and WAF configurations. These were addressed and recommended configurations were made for resolution.

Project delivery

A standard process was put in place to validate the requirements and meet the client’s expectations. After complete and thorough testing, we demonstrated and delivered the project to the client successfully.

Wrap up

Working on the telehealth portal as part of the ‘Digital Pakistan’ initiative was a short, knowledge-packed, and completely amazing journey that helped us learn and implement advanced quality assurance methodologies for a secure application. We adopted agile software quality practices to align software quality with product requirements and accelerate the software lifecycle. In addition, the continuous feedback we received from the project managers helped minimize retesting for verification and validation. Our iterative approach and short sprints enabled us to deliver quality products within a set deadline, successfully.

Thanks, team for all the amazing support. As I mentioned on slack, thanks to your hard work, we have 3000 doctors signed up and 1000 who submitted their documents. I had an amazing experience working with you all and truly admire your work ethic and efficiency. We couldn’t have done it without you. We will keep you updated on the stats and the launch event! — Project Coordinator, Digital Pakistan

Here’s where having a process-driven, and designed around ‘best-in-class’ software technologies delivery model helped us greatly.  It enabled robust scalability while maintaining cost-efficiency within strict quality control measures.

Thanks for stepping up to swiftly contribute towards our nation in these challenging times. It’s been a privilege to watch such a well-oiled team in action. — CEO, Digital Pakistan
