Know about CMMI

What is CMMI? CMMI (Capability Maturity Model Integration) is a training and appraisal program aimed at process improvement. It is a collection of very effective and reliable best practices which will help an organization improve its standard and quality. The model assesses current set of practices implemented by a system or an organization and identifies […]

ISTQB – Types of Experience Based Techniques – Software Testing

Experience-based techniques Black Box techniques are used to derive test cases from the specification available. White Box techniques supplement the Black Box techniques and use the code to derive test cases and increase the test coverage. How do we test when there is insufficient/no documentation and also a limited time frame? What do we use to […]

ISTQB – White Box Testing Techniques in Software Testing

Structure Based or White Box techniques White-box test design techniques (also called structural or structure- based techniques) are used to derive test cases from an analysis of the program(code). This article is devoted to understanding how to derive test cases from a program and also derive coverage metrics for tests undertake. Deriving test case after analysis […]

ISTQB – What is Use Case Testing in Software Testing

Use Case Testing The ISTQB syllabus expects the Software Tester at Foundation level to understand and explain Use Case testing (K2 level).  In contrast, the Software Tester has to apply the knowledge in selecting the test cases for the other Black Box techniques (Equivalence Partitioning, Boundary Value Analysis, Decision Table and State Transition – K3 […]

ISTQB – What is State Transition Testing in Software Testing

State Transition Testing Technique This technique falls under the Black Box testing techniques and the ISTQB syllabus excepts the tester to 1.  understand State Transition diagrams and State tables 2.  derive test cases from the State Transition diagrams and State Tables 3.  Sequences – shortest, longest sequences 4.  Null or Invalid transitions 5.  Chow’s switch coverage State-transition […]

ISTQB – What is Decision Table Testing in Software Testing

Decision Table Testing: Consider this  from an vehicle insurance Functional Spec: If the age of the driver is greater than 25 and the driver is female, offer a discount of 10%. In Equivalence Partitioning and Boundary Value Analysis, the focus was on single or specific inputs and probably more focused on UI. And the techniques […]

ISTQB – What is Boundary Value Analysis

Boundary Value Analysis: Boundary Value Analysis(BVA) comes from the  understanding that programmers  tend to make errors  around the boundaries eg. when using  equal to(=), greater than, less than, greater than-equal to, less than-equal to or the number of times a loop should be run. Boundaries are quite common in any program. For example, consider the driving […]

ISTQB – Equivalence Partitioning with Examples

Equivalence Partitioning: The word Equivalence means the condition of being equal or equivalent in value, worth, function, etc.    The synonyms for the word are equal, same, identical etc. Equivalence Partitioning is a black box technique to identify test cases systematically and is often the first technique to be applied when designing test cases. Equivalence Partitioning  […]

ISTQB Foundation: Black Box Techniques

Black Box Techniques These are test design techniques primarily used during System/Functional testing by the Testing team to design test cases. The word ‘BlackBox’ is key- the application under test(AUT) is treated as a Black Box or an opaque box, the tester is unconcerned about the internal working of the application. What the tester is […]
