Day 1: Introduction to Software Testing

             

   CLASS                                                                                                                                 INTERVIEW  

1. What is Software Testing?

• Definition: Software testing is the process of evaluating and verifying that a software application or system meets the specified requirements and functions correctly.
• Purpose: The main purpose of software testing is to identify defects, ensure the product is free of bugs, and verify that it meets the user's needs and expectations.

2. Why is Software Testing Important?

• Quality Assurance: Ensures the software is of high quality.
• Cost-Effectiveness: Identifies defects early in the development cycle, reducing the cost of fixing them.
• Customer Satisfaction: Ensures the final product meets user requirements and provides a good user experience.
• Security: Identifies vulnerabilities and ensures the software is secure.
• Compliance: Ensures the software complies with regulatory standards.

3. Basic Terminology in Software Testing

• Defect/Bug: An error, flaw, or fault in a software application that causes it to produce incorrect or unexpected results.
• Test Case: A set of conditions and steps used to determine whether a software feature works correctly.
• Test Plan: A document outlining the scope, approach, resources, and schedule for testing activities.
• Test Script: A set of instructions used to execute a test case.
• Test Suite: A collection of test cases intended to test a specific functionality or feature.

4. Types of Software Testing

Manual Testing:

• Definition: Testing software manually without the use of automated tools.
• When to Use: Suitable for exploratory testing, usability testing, and ad-hoc testing.
• Pros: Easy to learn, no programming knowledge required, immediate feedback.
• Cons: Time-consuming, prone to human error, not suitable for repetitive tasks.

Automated Testing:

• Definition: Using automated tools to execute test cases and compare the actual outcomes with expected results.
• When to Use: Suitable for regression testing, performance testing, and repeated execution of test cases.
• Pros: Faster, more accurate, suitable for large projects.
• Cons: Requires programming knowledge, higher initial setup cost, maintenance of test scripts.

5. Levels of Software Testing

Unit Testing:

• Definition: Testing individual components or modules of a software application.
• Performed By: Developers.
• Purpose: Ensures each component functions correctly in isolation.

Integration Testing:

• Definition: Testing the interactions between integrated units or modules.
• Performed By: Testers or developers.
• Purpose: Ensures combined units work together correctly.

System Testing:

• Definition: Testing the complete system as a whole.
• Performed By: Testers.
• Purpose: Validates the end-to-end functionality of the system.

Acceptance Testing:

• Definition: Testing the system to ensure it meets the business requirements.
• Performed By: End-users or clients.
• Purpose: Ensures the software is ready for deployment.

6. Software Development Life Cycle (SDLC) and Testing Phases

Requirement Analysis:

• Understanding and analyzing the testing requirements.
• Identifying what needs to be tested.

Test Planning:

• Creating a test plan document outlining the strategy, scope, resources, and schedule for testing.

Test Design:

• Designing test cases and test scripts.
• Preparing test data.

Test Environment Setup:

• Preparing the test environment.
• Ensuring all necessary tools and resources are available.

Test Execution:

• Executing test cases.
• Logging and reporting any defects found.

Test Closure:

• Ensuring all test cases have been executed.
• Preparing a test summary report.

7. Introduction to Test Management Tools

Manual Testing Tools:

• JIRA: A popular tool for bug tracking and project management.
• Bugzilla: An open-source bug tracking tool.
• TestLink: A test case management tool.

Automated Testing Tools:

• Selenium: An open-source tool for automating web applications.
• QTP/UFT: A commercial tool for functional and regression testing.
• JMeter: An open-source tool for performance testing.
• Appium: An open-source tool for automating mobile applications.

8. Best Practices for Beginners in Software Testing

• Understand Requirements: Thoroughly understand the software requirements before starting testing.
• Write Clear Test Cases: Ensure test cases are clear, concise, and comprehensive.
• Prioritize Testing: Focus on critical functionalities first.
• Communicate Effectively: Keep clear communication with the development team and stakeholders.
• Learn Continuously: Stay updated with the latest testing tools and techniques.
