It covers Software Testing foundation – Fundamentals of testing

  Software Testing Foundation – ISTQB-ISEB Topics

1. Fundamentals of Testing

Why is Testing Necessary?Human -> Error (mistake) -> Defect (fault, bug) which when executed may cause -> Failure
Measures the quality of the software
Gives confidence in the quality
Reduces the overall level of risk
How much testing? Depends on risk, safety & project constraints
 Testing ObjectivesFinding Defects
Providing information for decision-making
Preventing defects
Gaining confidence about the level of quality
 Seven Testing PrinciplesTesting shows the presence of defects
Exhaustive testing is impossible
Early testing
Defect clustering
Pesticide paradox
Testing is context-dependent
Absence-of-error fallacy
 Fundamental Test ProcessPlanning & Control
Analysis & Design
Implementation & Execution
Evaluating Exit Criteria & Reporting
Test Closure
 The Psychology of TestingThe mindset of Developer & Tester
Communication in a constructive manner
Test Independence
 Code of EthicsCode is necessary, among other reasons, to ensure information accessed by testers are not put to inappropriate use.

    Which of the following statements is true?

    a) Testing can show failures that are caused by defects
    b) Developers use debugging instead of testing
    c) Regression testing checks that the defect has been fixed
    d) Negative testing is not to be recommended

    for the following question, your answer is A. I feel that B can be considered a correct answer too

    • Hi @deepsisphere,

      I see your point and kind of agree with you. However, The focus here is on testing instead of dev, the answer is throwing just to trick the test.

      Usually, on the questions in ISTQB, one answer is absurdly wrong, one is wrong but not so obvious and the last two potential answers are to mix your feelings and trick your answer.

      I found that there are others that I challenge the answer in real life, but since this is so we can tick the box of passing the exam and gain the certification, I just make sure get the right answer and move on.

      Good spot and thanks for commenting.

    • Answer: C
      Regression test, If the code is changed tester need to test the application are working fine
      a) Yes, testing shows the bug but we rectify before caused failures
      b) Instead mean alternative, Developer just debugged teh application

    Which of the following statements are true?

    i. A defect is produced as a result of system failure
    ii. Failures can be caused by environmental conditions such as radiation
    iii. Defects, bugs and faults are the same thing
    iv. Failures can cause bugs
    v. Faults always cause system failures

    a) i, ii, v are true; iii and iv are false
    b) ii. iii. iv are true; i and v are false
    c) ii, iii, are true; i, iv, and v are false
    d) iv, v are true; i, ii and iii are false

    your answer is : c) ii, iii, are true; i, iv, and v are false
    but answer should be : a
    since Defects, bugs and faults are NOT same thing

    • Yeah. I thought so too. and on that topic, there is a lot of debate with different opinions about that specifically. But with the context of the ISTQB certificate, for the version of this exam, this is true. Thanks for commenting.

    • A defect, bug or a fault is a mistake that a programmer makes while developing a product. These mistakes basically turn out to be faults or errors in the software and are generally known as defects.

  3. If we check the definitions and Synonymous for the concepts we can see better the answer.
    Error, mistake, blunder
    Defect, Bug, Fault, Flaw
    Failure, Malfunction, Breakdown

  4. Hi! Why is it that the unlikely test objective is to assess regulatory compliance than proving that there are zero defects?

    In the 2023 CTFL syllabus, it says one objective is “Verifying that a test object complies with contractual, legal, and regulatory requirements”. Additionally, isn’t proving that there are zero defects kind of go against the testing principle i.e. “Testing shows the presence, not the absence of defects”? Thansk!
