Testing Types And Models

The document describes different types of software testing, including usability testing, functional testing, and non-functional testing. Usability testing includes user interface and manual support testing. Functional testing involves functionality, sanity, and smoke testing. Non-functional testing covers areas such as internationalization, recovery, compatibility, configuration, intersystem, installation, localization, performance, load, stress, data volume, parallel, and security testing. The document provides brief definitions and explanations of each type of testing.

This document provides an overview of software testing fundamentals and the software development lifecycle. It discusses different types of testing including static testing, dynamic testing, component testing, integration testing, and system testing. It also addresses test planning, management, and tools. The document emphasizes that early test design helps build quality and prevents faults by finding issues early when they are cheaper to fix. An experience report shows how early testing led to fewer faults and happier users compared to a previous phase without early 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.

Different types of software testing include installation testing, usability testing, regression testing, performance testing, and security testing. Installation testing checks that a system is correctly installed and functions properly on a variety of hardware configurations. Usability testing observes users interacting with a product to evaluate ease of use. Regression testing re-executes tests on software that has undergone changes to ensure no new bugs were introduced. Performance testing evaluates how fast a system performs under varying workloads through load and stress testing. Security testing verifies that a system protects against unauthorized access and vulnerabilities.

It also covers testing tools, test plans, test cases, and the software development life cycle.

The document discusses software testing, outlining key achievements in the field, dreams for the future of testing, and ongoing challenges. Some of the achievements mentioned include establishing testing as an essential software engineering activity, developing test process models, and advancing testing techniques for object-oriented and component-based systems. The dreams include developing a universal test theory, enabling fully automated testing, and maximizing the efficacy and cost-effectiveness of testing. Current challenges pertain to testing modern complex systems and evolving software.

The document discusses various aspects of software quality assurance (SQA) such as the role of the SQA group in preparing an SQA plan and reviewing software engineering activities to ensure compliance. It also covers SQA goals like requirements, design, and code quality. Statistical SQA involves collecting defect information to identify causes and fixes. Six Sigma methodology aims for high quality through defining, measuring, analyzing, and improving processes. Software reliability, availability, and safety are also addressed.

This document discusses test automation approaches and best practices. It defines test automation as using software to perform test activities like execution and checking results. The document outlines how test automation fits into the software development lifecycle and notes that reducing manual testing and redundant tasks is key to success. It also discusses factors to consider for test automation, types of tests that can be automated, and technologies used for test automation like object-based and image-based recognition.

The document discusses the definition and purposes of language testing. It defines a test as an activity meant to convey how well a test-taker knows or can perform something. Tests serve several functions, including reinforcing learning, assessing student performance, and providing diagnostic information. There are two main types of assessment: formative, to check student progress, and summative, used at the end to measure achievement. The document also outlines five common types of language tests: proficiency, achievement, diagnostic, placement, and direct/indirect. It discusses the advantages and disadvantages of different testing methods.

This document summarizes four types of language tests: proficiency tests, achievement tests, diagnostic tests, and placement tests. It provides details about each type of test, including their purposes, content, advantages, and disadvantages. Proficiency tests measure overall language ability regardless of training, while achievement tests measure success in achieving course objectives. Diagnostic tests identify strengths and weaknesses, and placement tests are used to assign students to appropriate class levels. The document also discusses additional topics in language testing such as direct vs indirect testing, and objective vs subjective scoring.

The document discusses different types of assessment including formal, informal, and self-assessment. It then describes various types of tests such as diagnostic tools, formal tests, informal tests, summative tests, formative tests, norm-referenced tests, and criterion-referenced tests. The final section outlines principles of test construction including validity, reliability, objectivity, discrimination, comprehensiveness, ease of administration, practicality and scoring, and usability.

This document discusses different ways to categorize tests, including by mode of response (oral, written, performance), ease of quantification of responses (objective vs. subjective), mode of administration (individual vs. group), test constructor (standardized vs. unstandardized), and mode of interpreting results (norm-referenced vs. criterion-referenced). Tests can be categorized based on whether responses are oral, written, or performance-based. Objective tests with quantifiable responses can be compared to yield scores, while subjective tests allow divergent answers like essays. Tests are also categorized by whether they are administered to individuals or groups, and whether they are standardized with established procedures or unstandardized for classroom use.

This document discusses different types of tests including true/false, short answer, essay, and matching tests. It provides details on each type, including guidelines for constructing them and advantages/disadvantages. True/false tests can assess basic knowledge but have high guessing rates. Short answer tests reduce guessing and assess lower-level thinking but are time-consuming to score. Essay tests measure higher-order skills but are difficult to score reliably. Matching tests are easy to construct and score but often assess trivial information. Proper construction and clear guidelines are important for all test types.

The document discusses different approaches to language testing including essay-translation, structuralist, integrative, and communicative approaches. It describes the characteristics and types of tests used in each approach, and highlights their strengths and weaknesses. Various language test techniques are also examined such as direct vs indirect testing, discrete point vs integrative testing, and objective vs subjective testing.

The document outlines different types of language tests: proficiency tests measure general language ability regardless of training; achievement tests relate to language courses and assess whether objectives were achieved; diagnostic tests identify strengths and weaknesses; placement tests determine what language level is appropriate. It also distinguishes between direct and indirect testing, discrete point and integrative testing, norm-referenced and criterion-referenced testing, and objective and subjective scoring. The document concludes by mentioning computer adaptive testing and communicative language testing.
