Interview Questions on manual testing
19. What is Software Testing?
A: This is a basic software tester interview question you could answer by saying; Software testing is a method of analysing whether a software product or an application matches the requirements it is made for. It is free of any issues like bugs. It ensures that the software application is working fine, complete, and superior, which helps smooth running. The errors are found using this method before the software reaches the end-users. It also makes sure that less maintenance cost is required in the future and gives more accurate and reliable results.
20. What is the difference between alpha testing and beta testing?
A: Alpha testing is a type of software testing carried out before making the software available for the end-users or market. It uses both white box and black-box testing. The internal employees of the company do it. It is the first stage of testing before moving forward to beta testing.
On the other hand, beta testing is carried out by the end-users of the software application. It uses only black-box testing and is performed by the customers who are not employees of the company.
21. What is the procedure for manual testing?
A: There are six stages involved in the procedure for manual testing:
- Check for the requirements- Go through the software requirement specification document, which will clearly understand the software to be tested and the end user’s expectations.
- Planning- plan the types of testing to be carried out, the scope of testing and the time in hand.
- Writing test cases- This document consists of high-level test scenarios and details entailing the scope of testing. There must be a clear overview of what is to be tested, how it is to be tested, the data to be used, and the output it will give.
- Review the test cases- The QA lead must review the test cases for any feedback or recommendation.
- Execution- This is the most crucial stage where the theoretical documents are brought into practicality. The plan is then executed and detected for any bugs.
- Report bugs- Bugs found, if any, have to be fixed, and the test has to be carried out again to verify it.
22. What is verified in white box testing?
A: The following is verified in white box testing:
- To ensure that the paths inside a module have been exercised.
- To ensure that the loops made on the boundaries are valid.
- To check if there are any security bugs in the code.
- Check all the loops in the code and the functionality of the application or software.
- Ensure that there are no typographical errors
- This can be due to the difference between the logical flow of the program and the actual implementation to discover the design errors.
23. Which are the different types of testing?
A: This is one of the most asked software tester interview questions; There is a total of three types of testing:
- Black Box Testing: Black Box testing is carried out with a person who has no idea about the internal workings or history of that application. In this, an input is provided, and it is observed to check the output generated by the system by putting it in a test. It shows the user actions, response time, usability and reliability issues.
- White Box Testing: White Box Testing is a method that analyses the internal structures or the working of an application. It shows not only internal design but also the code structures as well as the data structures.
- Grey Box Testing: Grey Box Testing is a combination of White Box Testing and Black Box Testing. It aims to search for any issues due to faults in the structure and usage of applications.
24. Explain the difference between a bug, a defect and an error.
A: A bug is a fault in the application which is detected in the testing process. They usually occur due to errors in the coding and lead to a functional issue.
A defect is seen after the product is released to the market. It is the difference between the output that was expected and the output that is seen.
An error is made by the software developer if there is any mistake or misconception in the product by software engineers, programmers, analysts and testers.
25. Explain the difference between test cases, test scenarios, and test scripts.
A: This is another most asked software tester interview question; A Test Scenario is a method that uses actual scenarios for testing the software applications to understand the complex problem in the software.
A Test Case is a method that contains the steps that should be taken. It is a document that is pre-planned after analysing the issues.
A Test Script is a programming language that helps the tester perform the testing of the systems as expected.
26. What is positive testing and negative testing?
A: Positive Testing: It shows what the system was supposed to do and checks the problem because it is failing to do the task. It helps to justify the outputs.
Negative testing: It is done to determine what the system was not supposed to do. Usually, if the system is performing differently than it has to, this testing is carried out.
27. Who prepares the contents of a test plan?
A: A test plan is prepared by the test lead or the test manager.
28. What are test deliverables?
A: Test deliverables are a set of documents that have to be developed and given to the stakeholder of a software project. These are handed over to the client along with the final delivery of the product.
