1.2.3. Errors, Defects, Failures, and Root Causes Human beings make errors (mistakes), which produce defects (faults, bugs), which in turn may result in failures. Humans make errors for various reasons,…
1.2.2. Testing and Quality Assurance (QA) While people often use the terms “testing” and “quality assurance” (QA) interchangeably, testing and QA are not the same. Testing is a form of…
1.2.1. Testing’s Contributions to Success Testing provides a cost-effective means of detecting defects. These defects can then be removed (by debugging – a non-testing activity), so testing indirectly contributes to…
1.2.Why is Testing Necessary? Testing, as a form of quality control, helps in achieving the agreed upon goals within the set scope, time, quality, and budget constraints. Testing’s contribution to…
1.1.2. Testing and Debugging Testing and debugging are separate activities. Testing can trigger failures that are caused by defects in the software (dynamic testing) or can directly find defects in…
1.1.1. Test Objectives The typical test objectives are: • Evaluating work products such as requirements, user stories, designs, and code • Triggering failures and finding defects • Ensuring required coverage…
Coverage - The degree to which specified coverage items are exercised by a test suite, expressed as percentage, synonyms - test coverage. Debugging - ”The process of finding, analyzing and…
6.1.Tool Support for Testing Test tools support and facilitate many test activities. Examples include, but are not limited to: • Management tools – increase the test process efficiency by facilitating…
5.1.Test Planning 5.1.1. Purpose and Content of a Test Plan A test plan describes the objectives, resources and processes for a test project. A test plan: • Documents the means…
4.1.Test Techniques Overview Test techniques support the tester in test analysis (what to test) and in test design (how to test). Test techniques help to develop a relatively small, but…
