Chapter 1: Test Analyst Tasks in the Test Process

Test Analysis

Test analysis identifies what to test by analyzing the test basis:

Activities:

• Identifying test conditions from requirements
• Evaluating test basis for testability
• Identifying required test data
• Designing test environment requirements

Test Conditions: A test condition is an item or event that can be verified by one or more test cases. Test analysts derive conditions from:

• Requirements specifications
• User stories and acceptance criteria
• Design documents
• Risk analysis results

Test Design

Test design determines how to test by creating:

High-Level Test Cases:

• Logical test cases without concrete data
• Focus on test steps and expected outcomes
• Support traceability to requirements

Low-Level Test Cases:

• Concrete test cases with specific data
• Exact input values and expected results
• Ready for execution

Test Implementation

Preparing for test execution:

Activities:

• Creating test procedures and scripts
• Prioritizing test cases
• Preparing test data
• Setting up test environment
• Creating test execution schedule

Test Execution

Running tests and recording results:

Test Analyst Responsibilities:

• Execute tests according to plan
• Log test results accurately
• Report defects with sufficient detail
• Participate in defect triage
• Perform confirmation and regression testing

Test Completion

Wrapping up test activities:

• Verifying all planned tests executed
• Ensuring defects properly logged
• Archiving testware for future use
• Creating test completion reports
• Identifying lessons learned

Chapter 2: Test Analyst Tasks in Risk-Based Testing

Product Risk Identification

Test analysts contribute domain expertise to identify product risks:

Risk Areas:

• Functional failures
• Non-functional quality issues
• Usability problems
• Data quality issues
• Integration failures

Identification Techniques:

• Expert interviews
• Brainstorming sessions
• Checklist analysis
• Historical defect analysis

Product Risk Assessment

Evaluating identified risks:

Likelihood Factors:

• Technical complexity
• Team experience
• Historical defect rates
• Degree of change

Impact Factors:

• Business criticality
• User visibility
• Financial consequences
• Safety implications

Risk-Based Test Prioritization

Using risk levels to guide testing:

Risk Level	Testing Approach
High	Test first, test thoroughly, test often
Medium	Test with standard coverage
Low	Test if time permits, basic coverage

Chapter 3: Test Techniques

This is the largest and most heavily weighted chapter. Master these techniques thoroughly.

Black-Box Test Techniques

Equivalence Partitioning (Advanced)

Beyond Foundation Level, understand:

• Multi-dimensional partitioning (multiple inputs)
• Combining partitions systematically
• Identifying non-obvious partitions

Boundary Value Analysis (Advanced)

Extended techniques:

• Three-value boundary analysis
• Boundaries in complex data types
• Boundaries in stateful systems

Decision Table Testing (Advanced)

Complex decision tables:

• Handling large numbers of conditions
• Collapsing rules with "don't care" conditions
• Limited-entry vs extended-entry tables

State Transition Testing (Advanced)

Beyond basic state machines:

• Creating state tables from diagrams
• N-switch coverage (sequences of transitions)
• Transition pairs and invalid transitions

Classification Tree Method

A systematic technique for test case derivation:

• Creating classification trees from requirements
• Combining classifications for test cases
• Ensuring coverage of relevant combinations

Using Checklists in Reviews

Develop review checklists for:

• Requirements completeness
• Requirements testability
• Design consistency
• Implementation correctness

Review Techniques for Test Analysts

Perspective-Based Reading: Apply the test analyst perspective - read requirements as if designing tests.

Questions to Ask:

• Can I write test cases from this?
• Are acceptance criteria clear and measurable?
• Are boundaries and edge cases defined?
• What test data will I need?

Chapter 6: Test Tools and Automation

• Test case management tools
• Requirements management tools
• Test data generation tools
• Model-based testing tools

Test Data Tools

Managing test data effectively:

• Data masking for privacy

• Data generation for coverage

Keyword-Driven Testing

Using keywords to separate test design from automation:

• Keywords represent actions
• Test analysts create keyword tests
• Automation engineers implement keywords

Benefits:

• Analysts design without coding
• Improved maintainability
• Reusable keywords across tests
