ISTQB Interview Questions

Q. What is the International Society for Testing and Quality Assurance (ISTQB)?
The International Software Testing Qualification Board (ISTQB) is a globally recognized software testing certification body. It is a non-profit testing organization created in November 2002 in Edinburgh. ISTQB is a testing organization based in Belgium operated by numerous volunteer test specialists from across the world.

Q. What are the different sorts of test techniques?
Defects are identified using test methodologies, which help minimize the number of test cases. The sorts of test methodologies are as follows:

  • Partitioning by equivalence
  • Analysis of boundary values
  • Cause-and-effect graphing/decision table testing
  • Tables of state transitions
  • All orthogonal testing/all pair testing Testing arrays
  • The method that does not need classification
  • Make use of case testing.

Q. In web testing, what kind of testing is considered?
Web testing may be divided into two categories: performance testing and security testing. Web testing ensures that your application is available through the internet. Web testing might check for different response codes and error messages depending on the online application.

Q. What is the significance of software testing?
The following are the most important factors:

  • To discover, fault, and fix flaws in software as it is being developed.
  • To guarantee that an application’s users or clients are satisfied and reliable.
  • Improve the software’s dependability and quality.
  • Ensure that your software applications are of excellent quality.

Q. What are the various black-box testing methods?
In black-box testing, the tester does not know the internal architecture or implementation of the capability. The following are examples of black-box testing techniques:

  • Techniques for equivalence partitioning tests
  • BVA (Boundary Value Analysis) is a test method.
  • Testing using a decision table
  • Testing of state transitions
  • Make use of case testing.

Q. What are the various test planning techniques?
There are four main test planning methods to choose from:

  • Acceptance testing
  • System testing
  • Integration testing
  • Unit testing.

Q. What are the many kinds of software testing techniques?
The many software testing approaches are as follows:

  • Testing by hand
  • Testing by robots
  • Performance evaluations
  • Testing for security
  • Testing in the dark
  • Testing in a white box

Q. What are the advantages of the ISTQB?
The key benefits of employing ISTQB methodologies are as follows:

The software testing tool has a straightforward design that is simple to operate.
Small software can benefit from software testing.
Early participation in testing is available.
The obvious link between the test and development stages.
Uncertainty and risk are controlled.

Q. What is acceptance testing, and how does it work?
The customer creates acceptance tests to see if the system performs as expected. Acceptance tests represent the interests of the consumer. The acceptance test assures the client that the application properly contains all of the essential features and functions.

Q. What is the definition of agile testing?
Agile testing is a sort of software testing that conforms to agile software development concepts. These testing activities are subject to agile testing:

Providing specific examples to guide growth
The inquiry is being asked to put ideas and assumptions to the test.
Exploratory testing and automated testing
Quality factors such as performance, dependability, and security are tested.

Q. What are the different Test Levels?
-Component Testing

-Integration Testing

-System Testing

-Acceptance Testing

Q. What are the different black box testing techniques?

-Equivalence Partitioning

-Boundary Value Analysis

-Decision Table Testing

-State Transition Testing

-Use Case Testing

Q. What are the different Test Planning activities?
-Determining the scope and objectives of testing

-Defining the overall approach of testing, defining entry and exit criteria

-Making decisions about what to test and who will test which part of the application

-Scheduling test design sessions

-Assigning resources for different testing activities

-Deciding which tools to use for testing

-Reporting on the progress of testing

-Producing exit reports

Q. What information should you include on a defect or bug report?

-Brief summary of the defect

-Full description of the defect including steps to reproduce

-Screenshot attachments if required

-Date the defect was found and raised

-Who reported the defect

-Severity and/or Priority of the defect

-Which component is the defect assigned

Q. Types of Software Testing?
Software Testing can be divided into two parts:

-Black box testing which is high level and does not take into account the internal workings of the software, i.e. the tester doesn’t need to know how each individual component interacts with each other.

-White box testing which tests at very low levels, e.g. functions within a class or component integration. System Testing is an example of a Black Box Testing, and Unit Testing is an example of white-box testing.

Q. What is Software Testing Techniques?
the main purpose of a Test Technique is to help identify defects and reduce a large number of combinations. Testing everything is not possible, because there is a large number of test cases that can be executed against a given application. Test techniques such as equivalence partitioning and pairwise testing reduce permutations, while boundary value analysis help to identify defects at boundaries.
