Positive testing A test aimed to show that the test object works correctly in normal situations. For example, a test to show that the process of registering a new customer functions correctly when using valid test data. Postconditions Environmental and state conditions that must be fulfilled after a test case or test run has been executed.
Preconditions Environmental and state conditions that must be fulfilled before the component or system can be tested. May relate to the technical environment or the status of the test object. Also known as prerequisites or preparations.
Quality assurance QA Systematic monitoring and evaluation of various aspects of a component or system to maximize the probability that minimum standards of quality are being attained. Record and playback tool Test execution tool for recording and playback of test cases often used to support automation of regression testing. Regression testing A test activity generally conducted in conjunction with each new release of the system, in order to detect defects that were introduced or discovered when prior defects were fixed.
Compare to Re-testing. Release A new version of the system under test. The release can be either an internal release from developers to testers, or release of the system to the client.
See also release management. Release management A set of activities geared to create new versions of the complete system. Each release is identified by a distinct version number. See also versioning and release. Release testing A type of non-exhaustive test performed when the system is installed in a new target environment, using a small set of test cases to validate critical functions without going into depth on any one of them. Also called smoke testing — a funny way to say that, as long as the system does not actually catch on fire and start smoking, it has passed the test.
Requirements management A set of activities covering gathering, elicitation, documentation, prioritization, quality assurance and management of requirements for an IT system. Requirements manager The person responsible for requirements management Also known as Requirements Lead or Business Analyst. Re-testing A test to verify that a previously-reported defect has been corrected.
Review A static test technique in which the reviewer reads a text in a structured way in order to find defects and suggest improvements. Reviews may cover requirements documents, test documents, code, and other materials, and can range from informal to formal. Reviewer A person involved in the review process that identifies and documents discrepancies in the item being reviewed. Reviewers are selected in order to represent different areas of expertise, stakeholder groups and types of analysis.
Risk A factor that could result in future negative consequences. Is usually expressed in terms of impact and likelihood. Risk-based testing A structured approach in which test cases are chosen based on risks. Test design techniques like boundary value analysis and equivalence partitioning are risk-based.
All testing ought to be risk-based. Sandwich integration An integration testing strategy in which the system is integrated both top-down and bottom-up simultaneously. Can save time, but is complex. Scalability testing A component of non-functional testing, used to measure the capability of software to scale up or down in terms of its non-functional characteristics. Scenario A sequence of activities performed in a system, such as logging in, signing up a customer, ordering products, and printing an invoice.
You can combine test cases to form a scenario especially at higher test levels. Scrum An iterative, incremental framework for project management commonly used with agile software development. Session-based testing An approach to testing in which test activities are planned as uninterrupted, quite short, sessions of test design and execution, often used in conjunction with exploratory testing. Severity The degree of impact that a defect has on the development or operation of a component or system.
State transition testing A test design technique in which a system is viewed as a series of states, valid and invalid transitions between those states, and inputs and events that cause changes in state. Static testing Testing performed without running the system. Document review is an example of a static test.
Stress testing shows which system resource e. Supplier The organization that supplies an IT system to a client. Can be internal or external. Also called vendor.
Contrast with Client. System The integrated combination of hardware, software, and documentation. System integration testing A test level designed to evaluate whether a system can be successfully integrated with other systems e. May be included as part of system-level testing, or be conducted as its own test level in between system testing and acceptance testing.
System testing Test level aimed at testing the complete integrated system. Both functional and non-functional tests are conducted. Test automation The process of writing programs that perform test steps and verify the result. Test case A structured test script that describes how a function or feature should be tested, including test steps, expected results preconditions and postconditions.
Test data Information that completes the test steps in a test case with e. In a test case where you add a customer to the system the test data might be customer name and address. Test data might exist in a separate test data file or in a database. Test driven development A development approach in which developers writes test cases before writing any code.
Test driver A software component driver used during integration testing in order to emulate i. For example, a test driver can emulate the user interface during tests. Test environment The technical environment in which the tests are conducted, including hardware, software, and test tools. Test level A group of test activities organized and carried out together in order to meet stated goals. Examples of levels of testing are component, integration, system, and acceptance test.
Test log A document that describes testing activities in chronological order. Test manager The person responsible for planning the test activities at a specific test level. Usually responsible for writing the test plan and test report. Often involved in writing test cases. Test object The part or aspects of the system to be tested.
Might be a component, subsystem, or the system as a whole. Test plan A document describing what should be tested by whom, when, how, and why. The test plan is bounded in time, describing system testing for a particular version of a system, for example. The test plan is to the test leader what the project plan is to the project manager.
Test policy A document that describes how an organization runs its testing processes at a high level. Test process The complete set of testing activities, from planning through to completion. The test process is usually described in the test policy. Test report A document that summarizes the process and outcome of testing activities at the conclusion of a test period. Also called test summary report. Test run A group of test cases e. Tests on one test level are often grouped into a series of tests, i.
Each series can be a test run. Test script Automated test case that the team creates with the help of a test automation tool. Sometimes also used to refer to a manual test case, or to a series of interlinked test cases. Test specification A document containing a number of test cases that include steps for preparing and resetting the system.
In a larger system you might have one test specification for each subsystem. Test stub A test program used during integration testing in order to emulate lower-level components. For example, you can replace a database with a test stub that provides a hard-coded answer when it is called. Test suite A group of test cases e.
Testing A set of activities intended to evaluate software and other deliverables to determine if that they meet requirements, to demonstrate that they are fit for purpose and to find defects. Top-down integration An integration test strategy, in which the team starts to integrate components at the top level of the system architecture. Traceability Analysis of a prior chain of events, as well as the ability to follow an object such as a document or a program through various versions.
Traceability enables you to determine the impact of a change in requirements, assuming you also develop a traceability matrix. Traceability matrix A table showing the relationship between two or more baselined documents, such as requirements and test cases, or test cases and defect reports. Used to assess what impact a change will have across the documentation and software, for example, which test cases will need to be run when given requirements change.
It is a evergreen sector in the IT sector. Here are the benefits of software testing: Software testing ensures that you deliver a quality product to the customer. Testing helps in removing risks and problems earlier. Testing any IT project on time helps you to save your money for the long term. The main aim of any product is to give satisfaction to their customers. Here are the reasons to choose software testing as a career : You can get a good salary and growth as a software testing professional.
Solving and tracking bugs is a fun activity You contribute to the quality of the software product, which is a very rewarding experience. People should choose software testing if they like to work in a challenging environment.
Report a Bug. Next Continue. A doorstop is a piece of non-functioning or outdated equipment inexplicably kept on premises — and perhaps its best use is as a doorstop. Not as a piece of IT equipment. When something is bug-for-bug-compatible, it was actually reproduced with the bugs intact. Therefore, retaining these bugs is sometimes important. Software rot is a hypothetical affliction that causes programs to run more poorly over time.
Brute force , in this case, has nothing to do with physical strength. If your hardware or software contains a bug that makes it unusable — i. The glossary of tech terms could fill several blog posts.
