Q22. What are the key challenges of software testing?
Ans. This is one of the commonly asked Test Lead interview questions. Some of the key challenges of software testing are:
- Testing the entire application: It is difficult to test the entire application as there are many test combinations. It will lead to a delay in shipping the product if you test all the combinations.
- Communication with developers: Developers or testers may not always agree with each other on some points.
- Regression testing: Managing the changes in current functionality and previous working functionality checks could be difficult.
- Time constraint: You may have multiple tasks related to quality that need to be completed within a specified time.
- Priority: With time constraints, it sometimes becomes difficult for the testers to decide which test to execute first.
Some other challenges include deciding on the right process and identifying the non-testable requirements.
Q23. What steps are followed to create a test script?
Ans. Below are the steps to create a test script:
- Understand the Application under test by reading the requirements related documents other references, such as the previous version of the application.
- Make a list of the areas to test for the AUT. In this step, you will identify ‘What’ to test.
- Determine ‘How’ to test them. Write various steps on how to test a particular feature, determine the data that will be entered, and the expected outcome.
Q24. Why testing is necessary?
Ans. Testing is an important step in the software cycle as it helps to identify defects, mistakes, and bugs before the delivery to the client. Testing ensures the quality of the software and produces a more cost-efficient end-product.
Q25. What is PDCA Cycle?
Ans. This is one of the frequently asked test lead interview questions. PDCA stands for Plan Do Check Act. The PDCA Cycle is a 4-stage problem-solving technique for conducting a quality check. It focuses on the continuous improvement of processes and products. In simple terms, it is a continuous loop of planning, doing, checking, and acting that is useful for testing improvement measures.
Q26. What is a bug?

Q39. What is the difference between Assert and Verify commands in test automation?
Ans. Both Assert and Verify commands are used to check if the code conditions are true. The difference is what happens next. There are some differences between Assert and Verify:
- If the Assert condition is true then the program control will execute the next test step. If the command fails, the execution will stop and further test steps will not be executed. There are two types of assets, namely Hard and Soft Asserts.
- When a Verify command fails, the test will continue executing the rest of the code and logging the failure. The Verify command is used to check non-critical things.
Q40. What is the difference between functional and non-functional testing?
Ans. Functional Testing
Functional testing tests the system against the functional requirements and specifications. It is concerned with the result of processing. Each functionality is tested by providing a test input, expecting the output, and comparing the actual output with the expected output.
Non-functional testing verifies the non-functional requirements of the application (all the aspects which are not tested in functional testing). It tests whether the behavior of the system is as per the requirement or not. It tests various aspects of the software such as load times, stress, and overall performance.
The table below lists some of the major differences between Functional and Non-functional testing:
|Functional Testing||Non-functional Testing|
|Tests the operations and actions of an application||Verifies the behavior of an application|
|Based on customer’s requirement.||Based on customer’s expectations.|
|Easy to execute manually.||Difficult to execute by manual testing.|
|Carried out using the functional specification.||Carried out by performance specifications.|
|Examples: Unit Testing, Smoke Testing, Regression Testing||Examples: Load Testing, Performance Testing, Stress Testing|
Q41. What is the difference between Beta and Pilot Testing?
Ans. The differences between Beta and Pilot testing are:
Beta testing is done when the project is about to release. The application is given to the end-users to check whether the application meets the user’s requirements or not. It is done before the final release when the development and testing are essentially completed. The Beta version is released to a limited number of end-users to obtain feedback on the product quality. The purpose of Beta testing is to identify defects and improve the quality of the application.
It is the real-world testing that is performed by a group of end-users before an application’s full deployment. A group of users uses the application in totality before the final launch. The purpose of Pilot testing is to evaluate the feasibility, time, cost, risk, and performance of the project.
The following are some of the differences between Beta and Pilot Testing
|Beta Testing||Pilot Testing|
|Performed to minimize failure risks.||Performed to verify the entire system.|
|Done after Pilot testing.||Performed before Beta testing.|
|Done in a development environment.||Done in a real environment.|
|Performed by end-users.||Performed by selected users.|
Q42. Explain bug leakage and bug release.
Ans. Bug leakage is when the bug is discovered by the end-users and not detected by the testing team while testing the software.
Bug release is when the software or application is released with a set of known bug(s). These bugs usually have low priority and severity. It is done when the company can afford the existence of a bug in the released software rather than the time or cost for fixing it in that particular version. Typically, these bugs are mentioned in the release notes.
Q43. What are the different states in a Defect/Bug Life Cycle?
Ans. Below are the different states in a defect/bug life cycle:
|New||It is the first state of the Bug Life Cycle. Any new defect identified by the tester will fall in the ‘New’ state.|
|Assigned||When the defect in the ‘New’ state is assigned to the development team for resolution, the status of the bug changes to the ‘Assigned’ state.|
|Open||In this state, the developer team works towards fixing the bug.|
|Fixed||After fixing the identified bug, the developer team marks the state as ‘Fixed’.|
|Pending Retest||After fixing the defect, the developer team passes new code to the testing team for Retest. The new state becomes ‘Pending Retest’.|
|Retest||The tester checks if the defect is fixed by the developer or not.|
|Reopen||After Retesting, if the defect is identified again, then the status of the bug is changed to Reopened. It will go back to the Open state and go through the life cycle again. Once again bug goes to the ‘Open’ state and goes through the life cycle again.|
|Verified||If the tester does not find any kind of defect, it is assigned the ‘Verified’ status.|
|Closed||If the bug has been resolved and it does not persist, the state is changed to ‘Closed’.|
Q44. What is Bug triage?
Ans. Bug triage refers to the process of prioritizing each bug based on its severity, frequency, and risk. The QA team validates the severities of the bug, makes the required changes, finalizes the resolution of the bugs, and assigns resources.
Defect/Bug Triage Process:
- Defect Review
Q45. What is the difference between Verification and Validation?
Ans. Verification involves checking if the software achieves its goal without any bugs. On the other hand, Validation checks if the software product is up to the mark. Below are some of the major differences between Verification and Validation.
|Verification evaluates the steps during the development phase and determines if they meet the user requirements.||Validation evaluates the product after the development process to determine if it meets the specified requirements.|
|Verification is performed before validation.||Validation is performed after verification.|
|It includes checking documents, design, code, and program.||It tests and validates the actual product|
|Verification does not involve executing the code.||Validation involves executing the code.|
|Verification used methods, such as reviews, walkthroughs, inspections, and desk checking.||Validation includes methods such as black-box testing, white box testing, and non-functional testing.|
|It finds the bugs before the development cycle.||It finds the bugs after the development cycle – the bugs that the verification process could not detect.|
|Verification conforms to the requirements specified in the SRS document.||Validation checks whether it meets the specified requirements or not.|
|Its focus is on – Are we building the product right?||Its focus is on – Are we building the right product?|
