The manual testing interview questions can be further divided into three categories:

• Basic
• Advanced
• Real-world Based

Let’s begin with the Basic Manual Testing Interview Questions

1. Define ‘Software Testing’

Software Testing is the process of determining the accuracy, completeness, and quality of created software. It consists of a set of actions designed to detect software flaws so that they may be addressed before the product’s release.

2. Why are Software Tests Necessary?

Software testing is required to ensure that the software application is safe and of sufficient quality to be published on the market. Here are some strong arguments to demonstrate the necessity for testing:

• It highlights the faults and mistakes that occurred throughout the stages of development.
• Reduces the number of code cycles by discovering problems at the earliest stage of development.
• Ensures that software programmes have cheaper maintenance costs and provide more accurate, consistent, and trustworthy outcomes.
• Testing guarantees that the consumer continues to find the business trustworthy and that their satisfaction with the software is maintained.
• Ensures that code is bug-free that the product’s quality satisfies market standards.
• Helps to ensure that the software does not produce any errors.

3. Which are the two primary types of software testing?

Software analysis is a vast field, however it may be roughly divided into two categories:

• Manual Testing – This is the traditional kind of software testing, in which test cases are executed manually without the use of test automation technologies. It indicates that the software programme is manually tested by QA testers.
• Automation Testing — This is the process of performing test cases with the help of devices, scripts, and software by repeating predefined operations. The objective of test automation is to replace manual human work with more efficient technology or equipment.

4. What are the various manual testing types?

Different manual testing types include:

• Unit Testing
• System Testing
• White Box Testing
• Black Box Testing
• Integration Testing
• Acceptance Testing

5. What benefits can manual testing offer?

Listed below are the benefits of manual testing:

• It costs less.
• You get precise and immediate visual input.
• Perfect for testing small modifications.
• Ideal for ad-hoc testing.
• Testers are not required to have any knowledge of automation tools.
• It is great for UI testing.

6. What disadvantages does manual testing have?

The disadvantages of manual testing:

• Highly prone to human mistake and hazardous.
• Manually doing tests such as load and performance testing is difficult.
• When performed manually, regression tests are very time-consuming.
• Manual testing has a fairly restricted scope in comparison to automated testing.
• Not appropriate for very big companies and time-bound initiatives.
• In the long term, testing manually is more costly due to the accumulation of costs.

Let us now discuss Advanced Level Testing Interview Questions for Experienced

1. When should manual testing be chosen over automated testing?

There are several instances where manual testing is preferable than automated testing, such as:

• Automated tests are intended to save time and resources, yet their design and maintenance require time and resources. For instance, if you are developing a modest promotional website, manual testing may be more effective.
• In ad-hoc analysis, there is no predetermined methodology. Ad-hoc testing is an unplanned type of testing in which the tester’s knowledge and intuition are the only factors that matter. This is possible via manual testing.
• Exploratory Testing demands knowledge, experience, analytical, logical, creative, and intuitive abilities from the tester. Therefore, human participation is essential for exploratory testing.
•  During usability testing, the analyst must determine how consumer friendly, efficient, or easy the programme or product is for end users. The most significant component is human observation, hence it appears more acceptable to manually test.

2. How are a bug, a defect, and an error different?

• A bug is a software flaw that is discovered during testing. It is caused by a coding fault that causes a software to malfunction. They may also result in a malfunctioning product. These are fatal mistakes that may prevent a feature from functioning, lead to a system breakdown, or create performance bottlenecks.
• A defect is a discrepancy between intended and actual outcomes, discovered by the programmer after the release of the product. The problem was discovered after the programme went into production. In basic words, it refers to a variety of issues with the software products’ outward behaviour or internal characteristics.
• Errors are mistakes, misunderstandings, or misconceptions made by software developers. Developers are engineers, coders, analysts, and testers. For instance, a developer may misinterpret a design language, or a programmer may erroneously enter the name of a variable — resulting in an error. Typically, when a software error occurs, the program’s functionality is altered.

3. What does the testing phrase “quality” mean?

Generally speaking, quality software is mostly bug-free, released on time and under budget, fulfils needs or expectations, and is maintainable. However, ‘quality’ remains a subjective notion. It depends on who the ‘client’ is and how influential they are in the grand scheme of things. For instance, each sort of ‘client’ will have a unique perspective on ‘quality’; for instance, the accounting department can describe quality in terms of profits, whilst an end-user might describe it as consumer friendly and bug-free.

4. Explain what a “critical bug” is.

We call a bug “critical” if it has the potential to disrupt the bulk of the app’s features. It indicates that a substantial amount of functioning or a critical system component is fully broken, with no solution available. The application cannot be delivered to end users until the critical problem has been fixed.

5. What are the characteristics of an effective test engineer?

In the software business, a software tester is a specialist who identifies the optimal way to test a certain product.

• A competent software tester should have a “test to break” mentality and the ability to see things from the customer’s perspective.
• A strong commitment to quality and preciseness
• To establish a productive relationship with developers, one must use tact and diplomacy.
• Capability to interact with technical and non-technical individuals
• Prior software development industry expertise is usually an advantage.
• Capacity to evaluate high-risk sections of an application in a constrained amount of time based on situational analysis and sound judgement.

Manual Testing Interview Questions for Experienced (Real-World Based)

1. How will you decide the end of the testing phase?

Choosing when to discontinue testing might be challenging. Numerous contemporary software programmes are so sophisticated and operate in such an interconnected context that exhaustive testing is impossible. Common considerations in determining whether to end testing include:

• Deadlines (testing deadlines, release deadlines, etc.)
• Test cases performed with a specified pass rate
• When the test funding runs out
• The extent of coding or function or requirements coverage reaches a certain level.
• The bug rate drops below a specified limit
• The end of the alpha or beta testing phase

2. How can a product be tested if the specifications have not yet been finalised?

A requirement stack for a product may not be accessible. 

• It may need substantial effort to establish whether a programme has significant unanticipated functionality, which would signal deeper flaws with the process of software development.
• If the capability is unnecessary for the application’s intended purpose, it should be eliminated. Alternatively, develop a test strategy based on the product-related assumptions. However, ensure that all assumptions are well documented inside the test plan.

3. How do you know when to use automated testing instead of manual testing?

In the following circumstances, automated testing should be preferred over manual testing:

• When tests demand frequent execution
• Tests consist of repeated procedures
• The tests must be performed in a regular runtime environment.
• When less time is available to finish the testing phase
• When a large amount of code must be periodically tested
• Every operation requires a report

4. Can automated testing substitute for manual testing?

Manual testing cannot be replaced by automation testing. No matter how effective automated tests are, it is impossible to automate everything.

• Manual testing plays a significant part in software design and is useful in situations when automation cannot be used.
• Manual and automated testing both have their own advantages and drawbacks. Manual testing can help us comprehend the overall issue and more freely explore various perspectives of tests.
•  Automated testing, on the other hand, helps save time in the long term by performing a huge number of surface-level testing rapidly.

5. How is exploratory testing defined?

Exploratory testing is the process of software testing in which testers learn about the testing process and test execution concurrently. This method is more of a hands-on approach, with testers actively participating in the testing process rather than just preparing it.
