What You Will Grasp:
Complex Manual Testing Interview Questions
Outlined below are several vital concepts that you should be familiar with before any manual testing interview.
Let’s dive deeper into each concept, with simple examples for clarity.
- Boundary Value Analysis
- Equivalence Testing
- Error Guessing
- Desk Checking
- Control Flow Analysis
Boundary Value Analysis
This is a method of selecting test cases/data based on the boundaries separating valid and invalid conditions. Tests are designed to examine both within and outside of these borders.
Test data is chosen, which lies along the “edges” of the input domain [or output range] classes, information frameworks, procedural specifications, and so forth, in addition to the actual boundary points or any range factors.
Options often include maximal, minimal, and trivial parameters or values.
For instance, input data from 1 to 10 (boundary value)
Testing input data at 0, 1, 2 to 9, 10, and 11.
Equivalence Testing
The system’s input space is divided into representative classes so that the total number of necessary test cases can be reduced to one-per-class. This reflects the minimum number of tests that must be executed.
For instance, valid data range is 1-10
Test sets: 2; 5; 14

Error Guessing
This is a test data selection technique where the selection criteria are values that look likely to cause errors. Error guessing mainly relies on experience, with aid from other methods like boundary value analysis.
The test designer predicts potential errors in a certain software type based on their experience and designs test cases to unearth them.
For instance, if any form of resource is allocated dynamically, then an ideal place to look for faults would be the de-allocation of resources.
Are all resources appropriately unallocated, or are some lost during the software’s operation?
Desk Checking
Desk checking is done by the developer of the system or program. The process involves thoroughly reviewing the product to ensure its structural integrity and whether it meets standards and requirements.
This is the most traditional way of inspecting a program or system.
Control Flow Analysis
It uses a graphical representation of the process of the program. In control flow analysis, the program graphs have nodes that denote a statement or section potentially leading to an unresolved branch.
The diagram displays program control flow from one section to another, as indicated by branches.
The purpose of control flow analysis is to identify potential issues in logic branches that could result in a loop condition or incorrect processing.
We hope this guide will help you excel in any Manual Testing interview.
