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…
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…
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…
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…
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…
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…
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…
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,…
ISTQB 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…
When we log defects there are two fields that we need to fill in - Severity and Priority. In this blog, we look at the differences between these and some typical scenarios. Defect Severity: This stands for the degree of…
