App testing course

Lesson 1 • What App Testing Is

Defines app testing, its objectives, and its place in the software development lifecycle. Establishes shared vocabulary used throughout the course.

Lesson 2 • Types of Applications to Test

Surveys native, hybrid, and web app architectures and their distinct testing challenges. Prepares learners to select appropriate strategies per app type.

Lesson 3 • Core Testing Terminology

Introduces essential terms: test case, test suite, defect, severity, and priority. Consistent terminology enables precise communication with development teams.

Lesson 4 • The Software Development Lifecycle

Maps testing activities to SDLC phases including planning, development, and release. Shows how early testing reduces cost and rework.

Lesson 1 • Selecting Testing Types and Levels

Matches testing types—unit, integration, system, acceptance—to project needs. Choosing the right level avoids redundant effort and coverage gaps.

Lesson 2 • Test Estimation Techniques

Introduces effort estimation methods including analogy, three-point, and work breakdown. Accurate estimates support realistic sprint and release planning.

Lesson 3 • Risk-Based Test Prioritization

Applies risk analysis to rank features by likelihood and impact of failure. High-risk areas receive deeper test coverage first.

Lesson 4 • Writing a Test Plan Document

Structures a formal test plan covering objectives, resources, schedule, and exit criteria. A complete plan aligns stakeholders before testing begins.

Lesson 1 • White-Box Design Techniques

Uses code structure—branches, paths, and conditions—to design targeted test cases. Complements black-box techniques for deeper defect detection.

Lesson 2 • Test Case Design Principles

Covers clarity, atomicity, and independence as core test case qualities. Well-designed cases reduce ambiguity and enable consistent execution.

Lesson 3 • Organising and Maintaining Test Suites

Groups test cases into logical suites and establishes maintenance practices for evolving apps. Organised suites speed up regression cycles.

Lesson 4 • Black-Box Design Techniques

Applies equivalence partitioning, boundary value analysis, and decision tables to derive test cases from requirements. Maximises coverage without exhaustive testing.

Lesson 1 • Executing Test Cases Systematically

Walks through structured test execution including logging results and capturing evidence. Systematic execution ensures reproducibility and audit trails.

Lesson 2 • Setting Up a Test Environment

Configures devices, emulators, and test data needed before execution begins. A stable environment prevents false failures and unreliable results.

Lesson 3 • Smoke and Sanity Testing

Distinguishes smoke tests from sanity tests and explains their role in build verification. Quick checks gate further testing and save team time.

Lesson 4 • Regression Testing Fundamentals

Defines regression testing and explains when and how to run regression suites after changes. Prevents previously fixed defects from reappearing in production.

Lesson 1 • Reporting UI and Usability Findings

Structures usability reports with screenshots, severity ratings, and improvement suggestions. Clear reports enable designers and developers to act quickly.

Lesson 2 • Cross-Device and Cross-Platform Testing

Validates consistent UI behaviour across different devices, OS versions, and screen resolutions. Inconsistencies caught here prevent negative user experiences at scale.

Lesson 3 • UI Testing Fundamentals

Covers what UI testing validates: layout, typography, colour, and interactive element behaviour. Establishes the difference between functional and visual correctness.

Lesson 4 • Accessibility Testing Basics

Tests apps against accessibility standards for users with visual, motor, and cognitive needs. Accessible apps meet broader user needs and compliance requirements.

Lesson 1 • API Testing Concepts

Explains REST and GraphQL API structures, HTTP methods, and response codes. Understanding API mechanics is prerequisite to writing effective API tests.

Lesson 2 • Executing API Tests with Tools

Uses API testing tools to send requests, inspect responses, and automate assertions. Hands-on tool use builds speed and repeatability in API validation.

Lesson 3 • Contract Testing Fundamentals

Introduces consumer-driven contract testing to verify API agreements between services. Contract tests prevent breaking changes from propagating across microservices.

Lesson 4 • Integration Testing Strategies

Tests interactions between app components, third-party services, and databases. Integration tests catch contract mismatches and data transformation errors.

Lesson 1 • Designing Performance Test Scenarios

Builds realistic user scenarios and load profiles based on expected usage patterns. Realistic scenarios produce actionable and credible performance data.

Lesson 2 • Security Testing Fundamentals

Introduces common app vulnerabilities including injection, broken auth, and data exposure. Understanding attack vectors enables testers to design targeted security checks.

Lesson 3 • Performance Testing Concepts

Defines load, stress, spike, and endurance testing and their distinct objectives. Selecting the right test type targets the most critical performance risks.

Lesson 4 • Analysing Performance Test Results

Interprets response time, throughput, and error rate data to identify bottlenecks. Data-driven analysis guides developers to the root cause efficiently.

Lesson 1 • Choosing an Automation Framework

Compares framework types—keyword-driven, data-driven, and behaviour-driven—against project needs. The right framework reduces maintenance and increases team adoption.

Lesson 2 • When and Why to Automate

Evaluates automation ROI by comparing setup cost against long-term execution savings. Knowing when not to automate is as important as knowing when to do so.

Lesson 3 • Writing Your First Automated Tests

Implements basic automated test scripts targeting UI and API layers of a sample app. Hands-on scripting builds confidence and reveals real automation challenges.

Lesson 4 • Integrating Automation into CI/CD

Connects automated test suites to continuous integration pipelines for automatic execution. Pipeline integration provides fast feedback on every code change.
