Study Notes

Expected Outcomes in Testing

Expected outcomes are determined by requirements specification, use cases, and user expectations.
Standard testing definitions are outlined by industry standards such as IEEE 829 and ISO/IEC 25010.

Cost of Fixing Faults

Cost to fix faults increases over time, particularly after software release, due to complexity and integration with other components.

Test Plan Document Exclusions

Test Plan document typically excludes detailed test cases, specific test data, and results of testing activities.

Reviews and Inspections in Testing

Reviews and inspections can be considered part of the broader testing process, emphasizing quality assurance.

Non-Performance Testing Aspects

Non-performance testing excludes aspects such as functionality and usability which do not assess system speed or resource usage.

Purpose of Unusual Scenarios in Design

Exercising obscure scenarios aids in identifying edge cases and ensures robustness of the application.

Primary Goal of Load Testing Tools

Load testing tools are primarily aimed at assessing system behavior under expected and peak user loads.

Test Coverage Analysis

Test coverage analysis is utilized to identify untested parts of the application and ensure comprehensive test suite effectiveness.

Importance of Web Testing

Critical aspects of web testing include cross-browser compatibility, security vulnerabilities, and performance under varying load conditions.

Class Testing Characteristics

A characteristic of class testing involves focusing on the behavior of classes and their interactions based on specific input data.

Purpose of Defect Tracking

Defect tracking serves to monitor and manage faults in software, ensuring they are addressed and resolved throughout the development lifecycle.

Identifying Areas for Testing

The best approach for identifying areas needing testing includes risk assessment, reviewing requirements, and analyzing previous defect reports.

Regression Testing Case Selection

Factors in regression test case selection include changes in code, impacted areas of functionality, and history of defects.

Benefits of Test Automation

Major benefits of test automation encompass increased testing speed, repeatability, and accuracy, enabling frequent regression testing.

Common Test Automation Problems

Challenges in test automation include maintenance of scripts, compatibility issues, and high initial setup costs.

Typical Testing Project Metrics

Metrics collected in testing projects often include defect density, test case execution rates, and percentage of test cases passed.

Baseline in Testing

A baseline refers to an established reference point that is used for comparison in future test evaluations.

Tax Rates for Salaries

Tax rate for the next £1500 of an employee’s salary is typically at the standard rate, while any income exceeding £1500 plus £28000 is taxed at a higher rate.

Boundary Value Examples

Boundary values are specific cases that lie at the limits of input ranges, crucial for effective boundary testing.

Test Coverage Criteria Misconceptions

A statement that is NOT true regarding test coverage criteria may include an unrealistic assumption of complete coverage equating to defect-free software.

Minimum Test Requirement for Comprehension

The minimum number of tests needed to ensure complete scenario coverage in a procedure involves exhaustive combinations and inquiries.

Test Objectives Exclusions

An example of an objective that should NOT normally be part of a test could be to achieve perfect coverage without context to risk and requirements.

Primary Purpose of Software Testing

The primary purpose of software testing is to ensure software quality by verifying that it meets specified requirements and is free of defects.

When is Enough Testing Performed?

Enough testing is considered performed when risk is mitigated to an acceptable level, and critical areas have been validated.

Best Source for Expected Outcomes in UAT

The best source of expected outcomes for User Acceptance Test (UAT) scripts is derived from user stories and actual end-user expectations.

Disadvantages of Recorded Tests

A disadvantage of capturing tests by recording manual actions includes potential inefficiencies and lack of flexibility in adapting to changes.

Characteristics of Good Testing

Characteristic of good testing across any lifecycle model includes thoroughness, traceability, and alignment with project goals.

Designing Test Cases

Designing test cases involves defining clear objectives, identifying inputs and expected outcomes, and ensuring traceability to requirements.
