Combinatorial testing is a method that can reduce cost and improve test effectiveness significantly for many applications. This finding has important implications for testing because it suggests that testing combinations of parameters can provide highly effective fault detection.

Then, what is meant by exploratory testing?

Exploratory testing is an approach to software testing that is concisely described as simultaneous learning, test design and test execution. While the software is being tested, the tester learns things that together with experience and creativity generates new good tests to run.

Similarly, what is decision table testing with example?

Decision table testing is black box test design technique to determine the test scenarios for complex business logic. We can apply Equivalence Partitioning and Boundary Value Analysis techniques to only specific conditions or inputs.

What is black box testing in manual testing?

BLACK BOX TESTING is defined as a testing technique in which functionality of the Application Under Test (AUT) is tested without looking at the internal code structure, implementation details and knowledge of internal paths of the software.

What are the types of black box testing?

Black Box Testing Techniques
  • Equivalence Partitioning.
  • Boundary Value Analysis.
  • Decision Table Testing.
  • State Transition Testing.
  • Error Guessing.
  • Graph-Based Testing Methods.
  • Comparison Testing.


What are equivalence classes in testing?

Equivalence partitioning or equivalence class partitioning (ECP) is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In principle, test cases are designed to cover each partition at least once.

What is state based testing?

State-based testing is a new method for testing object-oriented programs. The information stored in the state of an object is of two kinds: control-information and data-storage. The control-information transitions are modelled as a finite state automaton.

What is clean room testing?

Cleanroom testing and certification involves checking that the cleanroom is functioning to the specific parameters and ISO classification. The standards which cleanrooms are tested to are ISO14644-1, ISO 144644-2 and ISO 14644-3.

What is meant by regression testing?

Regression testing (rarely non-regression testing) is re-running functional and non-functional tests to ensure that previously developed and tested software still performs after a change. If not, that would be called a regression.

What is cause/effect graphing technique?

Cause Effect Graph is a black box testing technique that graphically illustrates the relationship between a given outcome and all the factors that influence the outcome. It is also known as Ishikawa diagram as it was invented by Kaoru Ishikawa or fish bone diagram because of the way it looks.

What is tree testing UX?

Tree testing is a usability technique for evaluating the findability of topics in a website. It is also known as reverse card sorting or card-based classification. A large website is typically organized into a hierarchy (a "tree") of topics and subtopics.

What is white box testing in software engineering with example?

WHITE BOX TESTING is testing of a software solution's internal structure, design, and coding. In this type of testing, the code is visible to the tester. It focuses primarily on verifying the flow of inputs and outputs through the application, improving design and usability, strengthening security.

How do you write a test case for white box testing?

Step-by-Step White Box Testing Example
  1. Step 1: Identify the feature, component, program to be tested.
  2. Step 2: Plot all possible paths in a flowgraph.
  3. Step 3: Identify all possible paths from the flowgraph.
  4. Step 4: Write Test Cases to cover every single path on the flowgraph.
  5. Step 5: Execute, rinse, repeat.

What is combinatorial test design?

Combinatorial Test Design. CTD takes a systematic approach to modelling the things that need to be tested, then uses advanced mathematics to dramatically reduce the number of test cases while ensuring coverage of conditions and interactions.

What is functional testing in software testing?

Functional Testing. FUNCTIONAL TESTING is a type of software testing whereby the system is tested against the functional requirements/specifications. Functions (or features) are tested by feeding them input and examining the output. Identify functions that the software is expected to perform.

What are the black box testing techniques?

Typical black-box test design techniques include:
  • Decision table testing.
  • All-pairs testing.
  • Equivalence partitioning.
  • Boundary value analysis.
  • Cause–effect graph.
  • Error guessing.
  • State transition testing.
  • Use case testing.

What are different types of testing?

Different Types Of Software Testing
  • Unit Testing.
  • Integration Testing.
  • System Testing.
  • Sanity Testing.
  • Smoke Testing.
  • Interface Testing.
  • Regression Testing.
  • Beta/Acceptance Testing.

What is system testing and its types?

SYSTEM TESTING is a level of testing that validates the complete and fully integrated software product. Ultimately, the software is interfaced with other software/hardware systems. System Testing is actually a series of different tests whose sole purpose is to exercise the full computer-based system.
