Software Testing Lecture Notes

Introduction

• Test Planning and Test Control are fundamental parts of the test process
• Test Planning: Initial phase involving preparation and strategy
• Test Control: Ongoing activity to measure and control test progress

Test Control

Definition

• Ongoing measurement and control of test progress
• Conducted daily to track defects and test case execution status

Key Activities

1. Monitoring Defects
   • Track defect status daily (raised, in progress, fixed, verified)
2. Tracking Test Cases
   • Monitor execution status (completed, pending, remaining)
3. Reporting
   • Daily reports provided to stakeholders on status and deviations from plan
4. Corrective Actions
   • Actions to align progress with plan (e.g., extra time, additional resources)
5. Release Decisions
   • Based on defect and test case status, decide on software release

Test Analysis and Design

Key Activities

1. Reviewing Test Basis
   • Analysis of documents (SRS, design docs)
   • Identify gaps and ambiguities early
2. Identifying Test Conditions
   • Define items/conditions to be tested
3. Designing Tests
   • Use design techniques (e.g., Equivalence partitioning, Boundary value analysis)
4. Evaluating Testability
   • Ensure requirements/system are clear and testable
5. Designing Test Environment
   • Determine hardware, software, and tools needed

Test Implementation and Execution

Key Activities in Implementation

1. Develop and Prioritize Test Cases
   • Convert test conditions into test cases
   • Prioritize based on risk
2. Create Test Suites
   • Logical collections of test cases
3. Prepare Test Environment
   • Set up required hardware/software

Key Activities in Execution

1. Executing Test Cases
   • Perform steps, check actual vs. expected results
2. Recording Outcomes
   • Log environment details, software version
3. Reporting Defects
   • If actual results don't match expected, log defects
4. Re-testing
   • After defect fixes, re-test to ensure correctness
