roceImagine constructing a house but skipping the inspection for half the foundation. Would you feel confident living in it? That’s exactly the gamble you take when your software lacks a thorough QA process.
In this article, we’ll dive deep into the QA process, its importance, and the steps and techniques that make it effective.
Quality Assurance (QA) is a systematic process to ensure that software meets defined standards of quality. It focuses on preventing defects in the development process by implementing and refining workflows, practices, and testing strategies.
QA ensures processes lead to quality, while QC verifies the product meets quality standards. Both are essential for delivering reliable software.
Here’s a simple comparison table for you:
Aspect |
Quality Assurance (QA) |
Quality Control (QC) |
Definition |
A proactive process to prevent defects by refining workflows and ensuring compliance with standards. |
A reactive process focused on identifying and fixing defects in the product. |
Objective |
Ensure quality throughout the development lifecycle. |
Verify that the final product meets quality expectations. |
Focus |
Processes, methodologies, and prevention. |
Product testing and defect detection. |
Timing |
Begins early in the development cycle. |
Conducted after development, during testing. |
Responsibility |
Owned by the entire team to build quality into the process. |
Primarily the testing team’s responsibility. |
Examples |
Developing test plans, defining standards, conducting audits. |
Executing tests, logging defects, retesting fixes. |
The QA process, at its core, is the software testing life cycle, which consists of 6 crucial steps:
In this phase, testers collaborate with stakeholders to gather and document requirements in a Requirement Traceability Matrix (RTM). This document forms the foundation for a robust testing strategy.
Key Roles Involved:
Clear communication is critical. Using approaches like Behavior-Driven Development (BDD) can simplify requirements and reduce ambiguities. Feasibility assessments also occur here; if constraints exist, they’re addressed through discussions with stakeholders to adjust expectations or find solutions.
Once requirements are clear, the Test Planning phase begins to formalize the testing strategy.
Key Elements:
A contingency plan is essential to handle unexpected challenges.

Testers create detailed test cases based on requirements and plans.

Effective test cases are clear, actionable, and focused on expected outcomes. Tools like Katalon Studio or Selenium simplify test case creation and tracking.
The test environment simulates real-world conditions for accurate testing.
Example Setup for Mobile Testing:
Ensuring the environment closely mirrors user scenarios is crucial for reliable results.
For example, these are the test environments you can use to run your tests with in Katalon Studio:
There are 2 approaches to test executions:
Manual Testing: testers execute test cases manually without using automation tools. It's best for exploratory testing, usability testing, or scenarios where human intuition is crucial.
Automated Testing: test cases are executed using automation tools/automation scripts. These tools/scripts command the system to perform the action on behalf of the human testers. It's Ideal for regression testing, performance testing, and repetitive tasks.
Both approaches are often combined in a hybrid strategy to maximize efficiency and coverage.
A test case has 5 different statuses as it goes through execution:

After all test cases have been executed, the focus shifts to analyzing the outcomes and creating the Test Report.
