We have already learned about the differences in quality assurance, how to carry out quality assurance, and its key principles. Let us know about the primary quality assurance process.

Main Stages in the QA Process

A QA process is a way to check if a product meets what is expected. Performing software testing might differ based on the organization and its needs, but the steps below are crucial to follow.

  • Requirement Analysis
  • Before starting any work, it's crucial to understand what's needed. The QA team carefully looks at all the software requirements, ensuring they are clear, complete, and ready for testing. It helps prevent problems down the road and guides the upcoming testing plans.

  • Test Planning
  • Building on the requirements, the QA team makes a plan for testing. This plan includes the scope of testing, budget, and deadlines. It also outlines the types of tests needed, reporting procedures, and how to track and handle any issues found during testing.

  • Test Design
  • With the plan in place, the QA professionals create detailed test cases covering all the requirements. These test cases outline the conditions, data, and steps needed to check specific functions of the software. Test engineers may experiment to find the best ways to design tests. They also prepare a testing environment that closely resembles the actual production setup.

  • Test Execution and Defect Reporting
  • The testing begins with unit tests. Manual testers follow the designed test cases, reporting any issues they discover. Automation engineers use scripts to run automated tests. Defects found are documented in a tracking system.

  • Retesting and Regression Testing
  • After fixing any identified issues, the team retests the affected areas to ensure the problems are solved without causing new ones. They also perform regression testing to check that the changes haven't negatively impacted existing functionality.

  • Release Testing
  • When the development team announces a new release, the QA team checks for changes that might affect the software's performance. They conduct smoke testing to ensure the release is stable. If everything looks good, they run specific test suites, and the results are documented and shared.

Now that you know what QA is all about and its process, let us look into the benefits of implementing the QA process below.

Why Should QA Processes Be Implemented?

Implementing a robust quality assurance process is essential for various compelling reasons. Let's explore the advantages of implementing a QA process and the risks of neglecting it.

Risks of Not Implementing a Quality Assurance Process

The quality assurance process is a systematic undertaking by software testers to evaluate whether a product aligns with defined quality standards. Overlooking this essential quality assurance process can impact product quality.

  • Dissatisfied Users: Software defects can drive away users, decreasing customer loyalty and dissatisfaction.
  • Reputation Damage: Negative reviews due to poor quality can harm your reputation and impact your brand image adversely.
  • Trust Issues: Subpar product quality erodes trust among users and potential investors, posing challenges for the business.
  • Sales Impact: Insufficient product quality undermines sales efforts, causing new customers to leave when unmet needs are met.
  • Compatibility Problems: Introducing updates without proper quality assurance may cause existing features to malfunction.
  • Distraction and Delays: Quality issues divert the team's focus, resulting in developers spending time fixing bugs instead of implementing new features.
  • Deployment Challenges: Quality issues can hinder the smooth deployment of new features, as the development team must address existing defects first.

Prioritizing the QA process is crucial to mitigate these risks, ensuring a high-quality product that meets user expectations and drives customer satisfaction.

Benefits of Implementing a QA Process

Conversely, a well-organized quality assurance process substantially benefits your business, enhancing product quality and customer satisfaction. These benefits include:

  • Time Dedication: Your team can dedicate more time to enhancing the product and introducing new features.
  • Reduced User Complaints: Satisfied users are less likely to raise complaints, reducing the workload on the customer support team.

  • Cost Minimization: Proper quality assurance helps minimize project costs, as preventing defects is more cost-effective than fixing them later.

In summary, implementing an effective quality assurance process is a strategic investment that safeguards against risks and elevates your product's overall quality and success.

Types of Quality Assurance Testing (Manual & Automation)

Quality assurance testing involves using different methods to check if software and apps work well. These testing techniques find problems, ensure the software follows the rules, and improve its quality. Now, let's explore the two main types of quality assurance testing.

Manual Testing

Manual testing involves human interaction with the software to validate its functionality and assess its usability. This approach enables testers to mimic real-world scenarios and analyze software from an end-user’s perspective.

Manual testing comes in various forms, each with its unique approach for different purposes and types of software. Here are some of the most frequently used testing types.

Functional testing

This testing focuses on the functional requirements of an application, testing various actions and system functions. It involves giving input to the system and comparing the actual output with the expected one. Test cases are created based on the software and customer

Functional testing typically performs the following checks:

  • Testers must understand how the application functions.
  • Always use the appropriate set of data for testing
  • The application's functional requirements should match the test data used for output.
  • Ensure that all test scenarios are covered.
  • Record and review the results against the expected output.

Regression testing

This testing is a part of functional testing performed to check if the software still works as intended after developers make changes or fixes. When developers enhance the software, it could unintentionally affect other application parts. Regression testing ensures new changes don't harm existing features or introduce new bugs. This type of testing can be done using automation tools like Selenium. It involves re-running a set of test cases that have previously passed to ensure everything still works correctly.


Usability testing

In simple terms, the tester checks how easy it is for users to use the application. It falls under black box testing, where the application is tested to ensure users can easily interact with its interface. Testing has three main aspects: convenience, usability, and learning ability.

Usability testing aims to ensure the quality and user-friendliness of the application. To explain, let's take the example of a gaming app. Usability testing for this app checks if it can be operated with both hands, examines the background color, looks at the vertical scroll, and more.

Different types of usability testing include:

  • Cross Browser Testing: This involves testing the application on other browsers, operating systems, and mobile devices to ensure it works well everywhere.
  • Accessibility Testing: This type of testing checks how accessible the software is for people with impairments. For instance, it looks at font size and color to accommodate visually impaired users and those with color blindness.
  • Exploratory Testing: This more informal type of testing aims to identify and address existing defects. It relies on the tester's business domain knowledge to validate the application.

Acceptance testing

After finishing unit, integration, and system testing in software application testing, the next stage guarantees the application's quality. The quality assurance team conducts tests based on predefined cases and scenarios to assess the quality. The quality assurance team examines the entire system's design and internal functions during acceptance testing. This step is essential in testing software apps because it considers the contractual and legal requirements set by the clients.

Manual testing becomes challenging as software complexity increases, which leads to a growing number of testing scenarios, and human errors in developing and testing also rise. Additionally, conducting manual tests across various browsers and platforms can be time consuming and requires more human resources to manage the testing process.

Automation testing can be beneficial in overcoming these manual testing challenges.

Automation testing

Automated testing uses automation testing tools and frameworks to test cases, compare expected and actual results, and detect defects. It provides efficiency, repeatability, and quick feedback on software quality. Various types of automated testing include

Unit testing

This type of testing is performed on specific components of the software applications' parts to ensure they work correctly. It is done by testing individual units or sections of the source code. Unit testing happens early in the software development, and developers carry it out.

There are two main types of unit testing:

  • White Box Testing: You check the internal structure of the code. It helps find any mistakes in how the application is designed. Data flow testing, path testing, decision coverage, and control flow testing are used here.
  • Gorilla Testing: In this type of testing, inputs are repeatedly applied to the module to ensure it works well and the application doesn't crash. It tests every part of the code using random inputs. It checks how robust the application is, and because it involves every module, it's also called fault tolerance or torture testing.

Integration testing

This testing type brings units or software application modules together to check how the system works. In simple terms, it involves combining and testing two or more modules of an application together.

Integration testing aims to discover bugs in how modules connect, how data moves, and how they interact. Testers explore how different units work together and produce results in various situations.

It helps identify errors related to performance, requirements, and functionality. While unit testing checks individual units to ensure they perform as expected, integration testing assesses how well these units work when combined.

There are three main types of integration testing:

  • Big Bang: This method combines all application modules to form a complete system, followed by bug testing.
  • Top-Down Approach: Initially, the top-level module is tested, then sub-modules are added and tested.
  • Bottom-Up Approach: Unlike the top-down approach, this testing starts by testing the lowermost modules. Then, a stepwise approach is used to add and test higher-level modules.

Performance testing

This type of testing checks if a software application meets its performance goals, like how fast it responds and how much work it can handle. This type of testing uses tools like LoadRunner, JMeter, Loader, and others.

There are different types of performance testing:

  • Load Testing: This checks if the software stays stable when it handles the expected number of users. For example, if your app handles 250 users at once with a response time of three seconds, load testing checks if it still works well with 250 or fewer users.
  • Stress Testing: This checks how the application holds up under more stress than designed. For instance, if the app is made for 5000 users with a response time of five seconds, stress testing checks how it performs with 5000 or more users.
  • Scalability Testing: This checks if the application can handle more load than it's designed for and finds out where it might crash. For example, suppose an app handles 3000 users with a response time of five seconds. In that case, scalability testing checks how the application handles more than 3000 users, gradually increasing the load to find the breaking point.
  • Flood Testing: This tests a database's stability and response time by transferring a large set of data. It checks how well the database can manage the data.
  • Endurance Testing: This ensures the application can handle a continuous load over time. It checks if the application works properly for an extended period.

Security testing

Software testing looks into security to uncover an application's risks, threats, and vulnerabilities. The goal is to prevent attacks and find weaknesses in the software system. It focuses on two essential aspects: authentication and authorization, making the application secure for handling confidential information.

Security testing also examines how the software behaves during hacker attacks and how it can maintain data security in such situations.

Different types of security testing exist

  • Penetration Testing: This evaluates the system for vulnerabilities against external hacking attempts. Authorized cyberattacks are conducted to understand the system's limits in terms of security. It involves SQL injection, Privilege Elevation, session expiry, and URL manipulation.
  • Vulnerability Scanning: Automated software scans the system for vulnerability signatures.
  • Security Auditing: This involves an internal inspection of applications and the operating system for security limitations. It also includes a line-by-line code inspection.
  • Security Scanning: This is done to find weaknesses in the system and network and provide solutions to reduce associated risks.
  • Ethical Hacking: This involves hacking. In that case, an organization's software system with the primary intention of uncovering security flaws.
  • Portability Testing: This type of testing checks how changes in the environment affect the software's performance. For instance, it assesses how the software works in different versions of operating systems or web browsers.

Automated testing provides benefits such as faster test execution, managing large test suites, and the ability to repeat test cases. It is especially advantageous for tasks like regression testing and situations that demand comprehensive test coverage.

By combining manual and automated testing methods, quality assurance teams can thoroughly check the software, find problems, and ensure its quality and reliability. Choosing the right testing tools and methods depends on project needs, deadlines, and available resources. Using a balanced approach to testing makes quality assurance efforts more effective and efficient, leading to top-notch software that meets user expectations.

Now that we are aware of the types of testing, let us look into the tools that can help us maintain the quality when performing testing and that makes the tester's life easy.
