1. Authentication and authorization?
- Authentication (Auth): Verifies the user's identity.
- Authorization: Determines the user's permissions.Defines what actions the user can perform.
2. Retesting and Regression testing? - Retesting involves testing a specific bug or issue after it has been fixed by the developer.
- Regression testing involves testing the fixed bug and the surrounding areas that may have been affected by the fix. verify that the software works as expected after changes?
Retesting - Testing only the affected area.
Regression Testing - Testing the affected as well as the unaffected areas.
3. Black Box, White Box, Gray Box Testing:
- Black box: Focuses on external behaviour and user interactions. No knowledge of internal code or structure required. Typically performed by testers, QA engineers, or end-users. Examples: Functional testing, User Acceptance Testing (UAT), Exploratory testing.
- White Box: Focuses on internal code structure and logic. Requires knowledge of programming languages and code. Typically performed by developers. Examples: Unit testing, Integration testing, Code reviews.
- Gray Box: Combines elements of black box and white box testing. Requires some knowledge of programming and code. Typically performed by testers with programming skills or developers. Examples: API testing, Database testing, Security testing.
4. Severity: Refers to the impact or effect of a defect on the application's functionality. Measures the defect's damage or risk
Priority: How soon will the defect be fixed?
5. Test scenarios focus on what to test, while test cases focus on how to test. Test scenarios define end-to-end functions to be tested, while test cases provide instructions on how to test specific features.
6. Alpha, Beta, Gamma Testing:
Alpha: Conducted by the in-house testing team. Focus on functionality.
Beta: Conducted by external customers, end-users, or a select group. Focus on real-world usage.
Gamma: Conducted by end-users and customers. For the final validation, focus on business requirements and user expectations.
7. Equivalence Partitioning:
- Equivalence partitioning is a black-box testing technique that divides input data into partitions.
- Test cases that cover all possible input scenarios reduce the number of test cases.
Example: Age (1-100)
Valid ages: 1-100
Invalid Ages:
Below 1 (e.g., 0, -1)
Above 100 (e.g., 101, 150)
Non-numeric input (e.g., "abc")
8. Smoke and Sanity testing
- Smoke testing - Focusing on Major functionalities in the software through positive test cases.
- Sanity testing - Focusing on Major functionalities in the software through positive and negative test cases.
9. Usability testing - Easy to use.
10. BUG - Caused by a programming error.
ERROR - Mismatch between expected and actual output.
DEFECT - When the actual output differs from customer expectations, it is considered a defect.
MISTAKE - An error made by the user.
11. Adhoc/Monkey testing - testing an application randomly without following the requirements. Here we check negative scenarios.
12. Compatibility testing - testing an application with different hardware and software.
13. Globalisation testing - testing an application which is developed for different languages.
14. Reliability testing - testing the functionality of an application for a long duration of time.
15. Accessibility testing - testing the application which is developed for physically challenged people.
16. Acceptance testing - testing the business scenarios of an application, which is done by the customer.
17. Aesthetic testing - Testing the beauty of the application. checking colour combination, font style, font size and attractiveness of an application.
18. Functional, integration and system testing are mandatory for every testing application.
19. Smoke, sanity, exploratory and ad-hoc testing are situation-based testing.
20. Recovery testing - Later, close the application and open it again, and see whether all the previous data is still available or not.
21. SDLC - It is the Software Development Life Cycle
It has different stages:
- Requirement Analysis
- Designing
- Coding
- Testing
- Deployment
- Maintenance
22. Agile Model - When a customer wants an application very fast, with less time, we go for this model.
23. STLC - Software Testing Life Cycle
It has different stages:
- Requirement Analysis
- Test Planing
- Test Designing
- Test Environment Setup
- Test execution
- Test Cycle Closure
24. Scrum terminology
Scrum is a version of agile.
- Epic - It is a complete set of requirements given by the customer.
- Sprint - It is the duration of time taken to work on 1 or more user stories. Each sprint can be either 2/3/4 weeks, depending on the customer's decision.
- Sprint planning meeting - It is a meeting which is conducted before the sprint starts.
- Sprint backlog - It is a user story which is not completed in that particular sprint and is carried into the next sprint.
- Sprint review meeting - In this meeting, the scrum master will check whether all the user stories are completely developed and tested, and it is ready to be released to the customer or not.
25. Requirement Traceability Matrix:
- It is a document which is prepared to check whether every requirement has at least one test case or not. RTM maps all the requirements with the test cases.
