Every enterprise is dedicated to maintaining and upgrading their product quality. Be it a consumer, a final user, or just an ordinary individual, each one anticipates quality in whatever they purchase.
The primary goal of each enterprise is to foster impeccable quality through their business operations.
How do we maintain quality? The solution is rooted in testing. The critical element to maintain quality is through extensive testing.
Testing’s success traverses various stages of the Software Test Life Cycle (STLC). However, the most impactful element is how effectively are test cases devised for applications or software?
The artistry of writing effective test cases lies in a tester’s ability to articulate cases that are not only easily understood by others but also warrant maximum test coverage.
Test cases provide a medium for testers to interact with applications or software for testing goals. Broadly defining, test cases serve as the principal method for testing applications or software. High-quality test cases are pivotal in pinpointing defects embedded in the system or software. As a result, crafting well-constructed and high-quality test cases is a vital component in testing.
This write-up majorly focuses on a pivotal test design technique for verifying fields in an application, aiding in crafting test cases for common situations across all applications.
The core principle of this technique is to present its utility in formulating optimal test cases offering maximum test coverage.
Introduction to FVT
In today’s world, yielding superior software presents a significant challenge that can’t be overlooked. Reliance on software is progressively growing. Simultaneously, the quality, functionality correctness, and software reliability are emerging as concerns.
Can the quality of software be quantified?
Indeed, testing is a crucial part in preserving the quality of a project or application.
How can we assure that test cases offer 100% test coverage?
Before testing an application, testers must create comprehensive test cases that others can easily comprehend and read. Test cases lay the foundation for testing and serve as tools for identifying defects in the application or system.
This article places emphasis on the effective creation of test cases via the field validation test design technique, quickly delivering maximum test coverage. This technique not only identifies potential problems during testing but also adds value to the project.
A technique is a process utilized to achieve a specific activity or task. This article sheds light on the field validation test design technique, which assists in capturing test cases effectively with minimal documentation.
The Field Validation Table (FVT)
- A Field Validation Table (FVT) is a model of a test design technique used for validating applications’ fields.
- This method is universally applicable to all kinds of applications that necessitate field validation.
Every field in an application should be meticulously validated to track potential defects that might otherwise go undetected. This method proves beneficial in recognizing underlying shortcomings in the application’s fields.
At times, testers might overlook the full validation of some fields in the application due to a lack of focus or awareness.
Typically, testers just verify the most frequently used combinations while examining fields in an application. Employing FVT, testers can swiftly discover defects inherent in the fields.
The field validation table technique further aids in guaranteeing that no defects exist in any field of the application.
For a tester, it’s vital to examine every facet of an application. From a developer’s viewpoint, defects recognized during field validation may have a lower severity and priority. However, it’s the prime duty of a tester to report them irrespective of their significance. For a tester, a defect, irrespective of its level, is a matter of concern.
Field validations directly influence an application’s usability. If any defect remains unidentified during System Testing and comes to light during User Acceptance Testing (UAT), the tester who validated and signed off takes the blame.
End users and customers have expectations from an application to be user-friendly in addition to having an efficient functionality. Even minor usability issues or trivial aesthetic flaws in the application or software might lead to a dissatisfied and annoyed user.
Therefore, testing every field in an application is of paramount importance for testers. Testers can use the Field Validation Table to thoroughly examine every field in an application.
#1) First and foremost, a generic or standard table for different data types must be created as shown below. This is a one-time activity that includes both valid and invalid entries.
Table 1: Standard or generic field validation table
During the testing of application fields, testers should refer to this Field Validation Table or the list of items mentioned in the table.
When an application or page contains multiple fields, referring to this table is quite useful. As human memory is limited, it’s recommended to have this table or checklist readily available and within reach before validating fields in applications.
#2) A table tailored to the application, comprising specific fields and other columns, must also be fabricated. This table allows every field in an application to be validated and expressly indicates the location and the test data causing the defect.

- Enhances productivity.
- Makes automation simpler using this table.
- Limits or eradicates defect leakage by fabricating this table early in a project.
- Easy to comprehend.
- Beneficial to both manual and automation testers.
- Ensures maximum test coverage using an input or reference table.
- Allows the creation of test cases for field validation in applications.
The Field Validation Table (FVT) is a test design technique beneficial for validating fields in applications. By providing comprehensive test coverage for field validation and tracking defects in the system or application, this method adds considerable value to the application.
Employing this field validation table empowers testers to contribute to delivering superior quality software by identifying even the minutest defects in any field of an application.
