Software testing strategies

Software testing techniques along with object oriented testing techniques delivered to post-graduate students of Object Oriented Software Engineering.

The document discusses various software testing strategies and techniques including unit testing, integration testing, validation testing, and smoke testing. It also covers test team roles, documenting test cases, debugging approaches, and when testing is considered complete. The main goals of testing are to find defects, validate that requirements have been met, and ensure proper functionality and performance. A variety of testing tools and strategies can be used including simulators, monitors, analyzers, and test data generators.

The document discusses various topics related to software testing including the necessity of testing, goals of testing, different testing methods like static vs dynamic testing and white box vs black box testing, different testing levels from unit to system testing, testing approaches like bottom-up and top-down, different types of testing like alpha and beta testing, and functional vs non-functional testing. It provides examples of beta tests and concludes that complete testing is infeasible due to time and resource constraints.

The document discusses various aspects of software testing including definitions, principles, objectives, types and processes. It defines testing as "the process of executing a program with the intent of finding errors". The key principles discussed are that testing shows presence of bugs but not their absence, exhaustive testing is impossible, early testing is beneficial, and testing must be done by an independent party. The major types of testing covered are unit testing, integration testing and system testing.

Software testing is the process of evaluation a software item to detect differences between given input and expected output. Also to assess the feature of A software item. Testing assesses the quality of the product. Software testing is a process that should be done during the development process. In other words software testing is a verification and validation process. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but are not limited to the process of executing a program or application with the intent of finding software bugs (errors or other defects). Software testing can be stated as the process of validating and verifying that a computer program/application/product: • meets the requirements that guided its design and development, • works as expected, • can be implemented with the same characteristics, • and satisfies the needs of stakeholders. Software Development Process Cycle:-  PLAN (P): Device a plan. Define your objective and determine the strategy and supporting methods required to achieve that objective.  DO (D): Execute the plan. Create the conditions and perform the necessary training to execute the plan.  CHECK (C): Check the results. Check to determine whether work is progressing according to the plan and whether the results are obtained.  ACTION (A): Take the necessary and appropriate action if checkup reveals that the work is not being performed according to plan or not as anticipated.

The document discusses software testing terminology, principles, and phases. It defines errors, faults, failures, and their relationships. It also covers software quality metrics and attributes like correctness, reliability, and maintainability. Twelve principles of software testing are outlined around test planning, invalid/unexpected inputs, regression testing, and integrating testing into the development lifecycle. The phases of a software project are described as requirements gathering, planning, design, development, and testing.

This document provides an overview of software testing, including definitions, purposes, strategies, methods, levels, types, and tools. It defines software testing as evaluating a system to determine if it meets requirements and works as expected. Testing is necessary to find errors, improve reliability and quality, and satisfy users. Strategies include unit, integration, and validation testing. Methods are divided into black-box and white-box testing. Levels include unit, integration, system, and acceptance testing. Types incorporate installation, compatibility, smoke, regression, alpha, and beta testing. Tools aid in test management, functional testing, load testing, and debugging.

Fundamentals of software testing, testing levels and types, testing throughout the software life-cycle, bug report and bug severity. Automated tests via selenium web-driver with a demo.

1. The document discusses key concepts in software engineering including failure, error, fault, and defect. 2. A failure occurs when software fails to perform its required function, an error is a mistake by a programmer, a fault is a condition that causes software to fail, and a defect is a bug or flaw in software. 3. The differences are that a defect is a programming mistake, an error causes a defect, a fault is a condition from an error that causes failure when the software does not function as required.

The document discusses various software development life cycle models and testing methodologies. It introduces the waterfall model, prototyping model, rapid application development model, spiral model, and component assembly model. It then covers testing fundamentals, test case design, white box and black box testing techniques, and the relationships between quality assurance, quality control, verification and validation.

The document discusses various aspects of software testing such as the definitions of testing, different testing methodologies like black box and white box testing, testing levels from unit to acceptance testing, and performance testing types including stress, recovery, and compatibility testing. It also covers testing tools, test plans, test cases, and the software development life cycle.

Functional testing types include: - Testing functionality according to requirements - Testing web services interfaces and compliance with standards - Conducting testing for software version changes and data migration Non-functional testing types include: - Performance testing to ensure systems meet specified performance levels - Load testing to identify bottlenecks and determine behavior under heavy loads - Stress testing to detect errors under excessive operational capacity - Compatibility testing to ensure applications work in different environments - Security testing to adopt security procedures and probe for vulnerabilities - Usability testing to evaluate from an end-user perspective
