Explain STLC with an Example

 


The Software Testing Life Cycle (STLC) is a series of phases that ensure software quality and functionality.

 


 

Let’s break it down with a healthcare example:

1. Requirement Analysis

Understand the requirements from a testing perspective. A hospital management system needs to track patient records, appointments, billing, and insurance claims. Testers review these requirements to identify what needs to be tested.

2. Test Planning

Define the strategy and plan for testing.  Plan the testing activities for the hospital management system, including resource allocation, tools, timelines, and risk management.

3. Test Case Development

Create detailed test cases and test scripts. Develop test cases for various scenarios, such as patient check-in, appointment scheduling, billing, and insurance claim processing. For instance, a test case might verify that a patient’s insurance details are correctly validated during check-in.

4. Test Environment Setup

Prepare the environment where testing will be conducted. Set up the hospital management system on test servers, ensuring it mimics the production environment. This includes configuring databases, network settings, and integrating with other systems like insurance databases.

5. Test Execution

Execute the test cases and report defects. Run the test cases on the hospital management system. For example, test the patient check-in process to ensure it correctly updates the patient’s status and sends notifications to the relevant departments.

6. Test Cycle Closure

Concludes testing activities, analyse results, and prepare test closure reports. Summarize the testing outcomes, including the number of defects found and fixed, and assess the overall quality of the hospital management system. Prepare a report detailing the testing process and results.

Example Scenario

Imagine a scenario where a patient checks in at a hospital. The system needs to:

  1. Validate the patient’s insurance details.
  2. Update the patient’s status in the system.
  3. Notify the relevant departments (e.g., billing, medical staff).

Testers would create test cases to ensure each of these steps works correctly. They would execute these tests in a controlled environment, report any issues, and work with developers to resolve them.

SUMMARY

The Software Testing Life Cycle (STLC) is an essential framework that guarantees the quality and reliability of software applications. By following a well-defined series of phases, from requirement analysis to test closure, STLC aids in identifying and fixing defects early in the development process. This not only improves the software's functionality and performance but also ensures it meets user requirements and industry standards.

In summary, following the STLC enables organizations to produce high-quality software products, minimize the risk of issues after release, and enhance customer satisfaction. By continually refining testing processes and methodologies, companies can maintain a competitive edge in the software market.

WHAT ARE THE BENEFITS IN FOLLOWING DEVOPS PRACTICES?

Image
  INTRO DevOps is a combination of the word’s "development" and "operations." In practice, it signifies a collaboration between development and operations teams. DevOps is a software development methodology that is frequently viewed as a process, a culture, or a framework of principles that enables organizations to deliver products quickly and on an ongoing basis.   KEY PURPOSE OF DEVOPS DevOps was developed to address the problems arising from the traditional practice of having isolated teams—where development, testing, and operations work separately on a single product. This separation often leads to inefficiencies, as each team has distinct priorities, tasks, and schedules that may not align with one another. The primary aim of DevOps is to establish a more unified development cycle. Additionally, embracing a DevOps culture can lead to greater team efficiency, quicker release cycles, and more effective feedback systems.   DEVOPS PRACTICES A few essential practice...

What are different types of non-functional tests

                                                                   Non-functional testing plays a vital role in software testing by examining the non-functional characteristics of a software application. In contrast to functional testing, which checks if the software executes its intended tasks accurately, non-functional testing evaluates the software's performance under different conditions. This encompasses aspects such as performance, scalability, reliability, usability, and security, among other factors. OBJECTIVES OF NON-FUNCTIONAL TEST §   The goals of non-functional testing include enhancing the usability, efficiency, maintainability, and portability of the product. §   It aims to minimize production risks and costs related to the non-functional features of the produc...

WHAT ARE THE DIFFERENT CEREMONIES IN AN AGILE SCRUM TEAM?

Image
       As we embark on our Agile journey, it’s essential to understand the key ceremonies that will guide our workflow and collaboration. These ceremonies are the backbone of our Scrum framework, ensuring that we stay aligned, transparent, and continuously improving.                                                      CEREMONIES IN AN AGILE SCRUM TEAM   In an Agile Scrum team, several key ceremonies play a crucial role in keeping the team aligned and productive. Here are the main ones: The Sprint: A sprint in Scrum is a fixed length of time (usually one month or less) where ideas are turned into value. Sprints occur consecutively until the product is complete (or without end). Often, teams measure their future in sprints. Backlog Refinement (Grooming): This ongoing process involves the team reviewing and prioritizing ...
