What is ISTQB foundation-level certification? The ISTQB Foundation-level Certification is highly sought-after in the world of software testing. It is recognized by the International Software Testing Qualifications Board (ISTQB) and is designed to provide individuals with the knowledge and skills needed for a career in software testing. The ISTQB certification exam is divided into […]
Read MoreExperience-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 […]
Read MoreStructure 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 […]
Read MoreUse Case Testing: The ISTQB syllabus expects the Software Tester at the 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 – […]
Read MoreState 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 […]
Read MoreDecision 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 […]
Read MoreWhat is Boundary Value Analysis? Boundary value analysis is one of the best testing techniques in the software industry for testing software functions. It tests and detects if the software functions perfectly with the boundary values. The above technique tests values on, inside and outside particular boundaries. Testers detect major issues by analyzing the boundary […]
Read MoreEquivalence 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 […]
Read MoreBlack 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 […]
Read MoreISTQB Test Analysis and Design: In the ISTQB syllabus, the Test Process consists of a five phases Plan, Design, Implement/Execute, Report, Closure. (Our blog titled “Software Test Life Cycle” has more details .) The second phase of the Software Test Life Cycle is Test Analysis and Design, where specifications are analysed and test cases designed. This […]
